  • 00:00:00
    okay so today I'm going to do something
  • 00:00:01
    different we are uh going to look at
  • 00:00:05
    some questions that the Discord folks
  • 00:00:08
    have been asking about and I figured I
  • 00:00:10
    might as well just do this on stream in
  • 00:00:12
    case somebody else wants to hear the
  • 00:00:15
    answer to those questions uh so I'm
  • 00:00:16
    going to go through a couple things in
  • 00:00:18
    my Discord and there are about 15
  • 00:00:23
    comments on YouTube I got to get through
  • 00:00:25
    so let's just do it together today and
  • 00:00:27
    see how it goes and if you have any
  • 00:00:28
    questions if you're on uh let me know
  • 00:00:32
    and I will do my best to at least
  • 00:00:34
    investigate them or try to try to get
  • 00:00:37
    you pointed in the right direction if I
  • 00:00:39
    can so Nova Leaf uh you've been looking
  • 00:00:42
    at you've been making something custom
  • 00:00:44
    and it looks like you're doing some kind
  • 00:00:45
    of Destruction uh mechanisms you've been
  • 00:00:48
    building it yourself I've been watching
  • 00:00:50
    your updates over the last few weeks um
  • 00:00:52
    looks like you are making progress I did
  • 00:00:54
    check this out the other day
  • 00:00:57
    um I just wanted to check in on this
  • 00:00:59
    again and see
  • 00:01:04
    that pretty cool I don't I don't know
  • 00:01:08
    where you're going with this or where
  • 00:01:09
    he's going with this but it it looks
  • 00:01:11
    cool um I'm excited to see what what
  • 00:01:14
    what ends up coming of this so anyways
  • 00:01:16
    Nova if you end up stopping by let me
  • 00:01:18
    know um we got a couple more followers
  • 00:01:21
    it looks like since the last stream
  • 00:01:23
    looks like I got three three to four
  • 00:01:25
    more so we're almost at that 20 Mark
  • 00:01:27
    goal so if you guys are in the channel
  • 00:01:29
    and you want to support us uh please
  • 00:01:32
    give us a follow so we got ebi um wanted
  • 00:01:35
    to purchase a virtual private server is
  • 00:01:39
    that what that means I usually I'm
  • 00:01:41
    usually refer to that VPC uh virtual
  • 00:01:44
    private Cloud but I guess virtual
  • 00:01:46
    private server um they want to run a
  • 00:01:48
    build for multiplayer
  • 00:01:50
    game so that's something
  • 00:01:53
    like what kind of server configuration I
  • 00:01:56
    need all right well that is like Nova
  • 00:01:59
    said that's
  • 00:02:00
    that's really hard
  • 00:02:02
    to narrow down exactly what type of
  • 00:02:05
    server you would need I would say that
  • 00:02:07
    you could probably get away with
  • 00:02:10
    starting out because because it sounds
  • 00:02:13
    like you're starting out just start with
  • 00:02:15
    a bare minimum server pick any cloud
  • 00:02:18
    service that allows you to host Linux um
  • 00:02:22
    so I guess maybe I could I'm going to
  • 00:02:24
    reply to this person in real time um so
  • 00:02:27
    I you know I would say use any cloud
  • 00:02:31
    provider like AWS that's what I'm
  • 00:02:34
    familiar with um or whatever and spin up
  • 00:02:39
    the smallest uh Linux Linux server um
  • 00:02:45
    build your game as a dedicated server
  • 00:02:51
    and run it there uh this is great for
  • 00:02:55
    testing I've done I've launched probably
  • 00:02:58
    a million instances
  • 00:03:00
    in my career and they are very handy you
  • 00:03:04
    can SSH to them you can run commands to
  • 00:03:06
    them you can monitor them uh with a with
  • 00:03:08
    the cloud infrastructure like AWS AWS is
  • 00:03:11
    a behemoth it's this massive product but
  • 00:03:16
    there are some cheap ways with it like
  • 00:03:18
    if you sign up you you can have you get
  • 00:03:21
    like what was it um was it 500 hours I
  • 00:03:23
    think it was like 500 hours a month of
  • 00:03:25
    runtime so if you're new Game Dev and
  • 00:03:28
    you just want to spin up a VPC for free
  • 00:03:30
    uh yeah you got to have a credit card
  • 00:03:32
    but consider consider looking at uh you
  • 00:03:36
    know that kind of thing I I'm not
  • 00:03:38
    plugging for AWS by any means but it's
  • 00:03:40
    just what I know so I'm going to just
  • 00:03:42
    transfer some knowledge but if you like
  • 00:03:44
    a better cloud provider please check
  • 00:03:46
    that out there are other services so I
  • 00:03:50
    have an internal document of resources
  • 00:03:54
    that I'm I'm just jotting down and I I
  • 00:03:58
    guess I can share some of this
  • 00:04:00
    but there are several different Services
  • 00:04:05
    out there like I have AWS just kind of
  • 00:04:07
    commented in the middle um from W4 which
  • 00:04:10
    is a gdau specific product that is in
  • 00:04:14
    very early beta and it is invite only or
  • 00:04:18
    on request only and as a side note I
  • 00:04:20
    actually just got access to it so I'm
  • 00:04:22
    super excited to get into that um
  • 00:04:26
    looking forward to see what comes at and
  • 00:04:27
    I'll probably do some videos covering
  • 00:04:29
    the W4 for folks cuz that those are made
  • 00:04:31
    by like gdau senior gdau members and
  • 00:04:33
    Silent wolf was something I just
  • 00:04:35
    discovered the other day uh you could
  • 00:04:37
    probably host it looks like a back-end
  • 00:04:39
    service there they
  • 00:04:41
    are doing this out of their own dime so
  • 00:04:45
    they're going to do it until they can't
  • 00:04:46
    do it anymore so if you're making a game
  • 00:04:48
    that isn't going to be a big deal on the
  • 00:04:50
    back end you can probably get away with
  • 00:04:51
    using these guys for a little bit uh I
  • 00:04:53
    actually like that idea I was thinking
  • 00:04:55
    about running my own backend service
  • 00:04:57
    like this where you just throw up a you
  • 00:04:58
    know dedicated Linux server you have a
  • 00:05:00
    nice interface um if you want me to make
  • 00:05:02
    that for you guys for maybe like low
  • 00:05:04
    cost or something let me know um cuz I
  • 00:05:07
    was considering doing that as a side
  • 00:05:09
    project uh GD sync is another one but
  • 00:05:11
    they're PD P2P only so that that really
  • 00:05:14
    doesn't uh work here in that situation I
  • 00:05:17
    don't believe this question was P2P
  • 00:05:20
    related digital ocean of course heroic
  • 00:05:22
    Labs but hero glavs is really expensive
  • 00:05:26
    I don't know how good their free tier is
  • 00:05:29
    play Cloud flow so you get a oneclick
  • 00:05:31
    server a 1 hour session for free
  • 00:05:36
    hostinger and uh Microsoft of course
  • 00:05:40
    yeah so I I really I really think that
  • 00:05:43
    this is the best way to do it though
  • 00:05:44
    just start small um run a couple tests
  • 00:05:47
    with whatever I don't know what type of
  • 00:05:48
    game like some people run multiple
  • 00:05:51
    instances of their backend server on a
  • 00:05:53
    single instance and there's nothing
  • 00:05:55
    wrong with that as long as it can handle
  • 00:05:57
    it as long as whatever instance you have
  • 00:05:58
    and some of these Services I've been
  • 00:06:01
    covering will probably vary in the
  • 00:06:05
    resources like your compute you know how
  • 00:06:07
    much uh the processor right so like
  • 00:06:10
    compute and uh RAM and memory and that
  • 00:06:12
    kind of thing how much hard drive or
  • 00:06:15
    virtual storage do you have how much
  • 00:06:18
    input and output can you transfer right
  • 00:06:20
    so there's gigabyte limits likely for
  • 00:06:23
    each one of these servers so consider
  • 00:06:25
    that when you're weighing in the costs
  • 00:06:28
    and look at each one of these services
  • 00:06:30
    to make sure that it's it's going to
  • 00:06:32
    make sense for your uh for whatever your
  • 00:06:35
    game is so if you are
  • 00:06:37
    running five instances of your backend
  • 00:06:40
    server because you want to have five
  • 00:06:42
    instances of your game or five maybe
  • 00:06:44
    matches maybe you have like a match
  • 00:06:46
    maker Style game uh that that could work
  • 00:06:49
    too and you know start with that run
  • 00:06:52
    some performance tests and just see how
  • 00:06:55
    much you know run a I can't remember on
  • 00:06:58
    top of my head if I remember I'll say it
  • 00:06:59
    but anyways you can manage or uh capture
  • 00:07:02
    like a performance snapshot of your
  • 00:07:04
    instances some of those Services may not
  • 00:07:06
    give you access to that some of them
  • 00:07:09
    might I know AWS does you can see like
  • 00:07:11
    your maximum CPU usage and if it looks
  • 00:07:14
    like you're never hitting that on those
  • 00:07:16
    small T2 instances right when you start
  • 00:07:17
    out with AWS they give you that the free
  • 00:07:21
    instances are like T2 micros and you
  • 00:07:24
    might never hit the max memories or
  • 00:07:26
    anything like that for whatever your
  • 00:07:28
    game is so um and like I said it it
  • 00:07:31
    really depends on the how you're running
  • 00:07:33
    your game are you running a static world
  • 00:07:34
    or a persistent world where it's going
  • 00:07:37
    to be running all the time or is it
  • 00:07:39
    going to be match based where maybe you
  • 00:07:41
    don't want to have a server running all
  • 00:07:42
    the time and you spin it up because you
  • 00:07:44
    have this Matchmaker process um I was
  • 00:07:47
    thinking about building an
  • 00:07:49
    architecture kind of an example for the
  • 00:07:52
    game I'm working on uh the that I
  • 00:07:54
    started during the game Jam where you
  • 00:07:56
    have like a
  • 00:07:58
    Matchmaker that
  • 00:08:00
    spins up ec2 instances which are under
  • 00:08:03
    AWS right if somebody joins and they a
  • 00:08:07
    match is made so they find somebody else
  • 00:08:09
    wants to play then at that point we spin
  • 00:08:11
    up an ec2 server on demand because if if
  • 00:08:15
    you just have an ec2 server running
  • 00:08:17
    you're going to blow through your free
  • 00:08:18
    tier and if you don't have a free tier
  • 00:08:19
    well either way you're going to have
  • 00:08:22
    charges that will accumulate because
  • 00:08:24
    you're just going to have that ec2
  • 00:08:26
    instance waiting for people to play
  • 00:08:28
    games on even though you're not even
  • 00:08:30
    using it so that's if you just want to
  • 00:08:33
    have a really quick access like if you
  • 00:08:35
    have funding or something maybe I can
  • 00:08:36
    consider doing that but if you don't
  • 00:08:38
    have funding and you're doing this out
  • 00:08:39
    of your own dime you know consider
  • 00:08:40
    making an architecture like that where
  • 00:08:42
    you spin up an instance and I think we
  • 00:08:45
    can get away with it now
  • 00:08:47
    because those ec2 instances spin up
  • 00:08:50
    really fast now like before it would
  • 00:08:52
    take like five minutes but those T2
  • 00:08:54
    micros spin up super fast and there
  • 00:08:56
    might even be more like um
  • 00:09:00
    what's it like serverless style AWS
  • 00:09:03
    resources I think they're going to be
  • 00:09:04
    more expensive they're a newer
  • 00:09:06
    technology and I haven't had a chance to
  • 00:09:08
    play around with it so I do want to look
  • 00:09:09
    into those one day and see if uh that's
  • 00:09:13
    something that is realistic or as
  • 00:09:15
    affordable because then you just tell it
  • 00:09:17
    you can hone in on exact on the exact
  • 00:09:21
    resources that you want like I need you
  • 00:09:22
    know three c v virtual CPUs and this
  • 00:09:26
    much RAM to handle this my resources so
  • 00:09:28
    you can really dial it in and I I think
  • 00:09:31
    I mean you can kind of do that with the
  • 00:09:32
    Standalone instances but I think they
  • 00:09:34
    have these more resource based models
  • 00:09:38
    with some of their stuff um I think ECS
  • 00:09:40
    is like a scalable product that they
  • 00:09:42
    offer that might off might have that but
  • 00:09:45
    I don't know if they offer that
  • 00:09:45
    Standalone I'd have to look that up it's
  • 00:09:47
    been a couple years since I've seen that
  • 00:09:50
    so yeah so a small VPS this guy's this
  • 00:09:53
    guy uh this person is correct um you're
  • 00:09:56
    out five bucks and the thing that's nice
  • 00:09:58
    about these so AWS is nice and you have
  • 00:10:01
    a limited amount of hours that you get
  • 00:10:02
    for free I think I said it was 500 free
  • 00:10:05
    tier and I think that'll give us right
  • 00:10:08
    into right into what we want let's
  • 00:10:12
    see
  • 00:10:16
    free oh I was way I was lowballing it
  • 00:10:19
    it's 750 hours for the first 12 months
  • 00:10:23
    per month so you get 750 hours of
  • 00:10:25
    runtime
  • 00:10:27
    so um if you're if you're testing 40
  • 00:10:31
    hours a
  • 00:10:32
    week uh 4 8 12 I mean you're not even
  • 00:10:35
    going to hit that if you tested if you
  • 00:10:38
    ran that server if you had like a day
  • 00:10:40
    job or something you were running it 40
  • 00:10:41
    hours a week you wouldn't you wouldn't
  • 00:10:42
    even get near that so um yeah so
  • 00:10:44
    consider I think my math is right on
  • 00:10:46
    that 40 hours a week yeah so anyways
  • 00:10:49
    consider whatever AWS or not I don't
  • 00:10:51
    care or if you want pay for a you know
  • 00:10:54
    you can and you can buy like like this
  • 00:10:56
    person saying you can buy one of these
  • 00:10:58
    vpcs from one of these providers and get
  • 00:10:59
    it for like a flat $5 fee there the good
  • 00:11:03
    thing about that is there's not going to
  • 00:11:04
    be any surprises you're not going to be
  • 00:11:07
    hit with a big Bill at the end of the
  • 00:11:08
    month because those other companies like
  • 00:11:11
    these ones down here are probably going
  • 00:11:12
    to cap you at that whatever they're
  • 00:11:15
    offering for that $5 amount whereas AWS
  • 00:11:17
    if you exceed that you will be built for
  • 00:11:20
    it um so what I always like to say is if
  • 00:11:23
    you are using any of these big cloud
  • 00:11:25
    providers like Google Red Hat Amazon uh
  • 00:11:28
    Microsoft
  • 00:11:29
    the first thing you need to do after
  • 00:11:30
    your create account is figure out how to
  • 00:11:32
    create a an alert that's going to email
  • 00:11:36
    you on a threshold of a certain budget
  • 00:11:40
    and I actually have a video for how to
  • 00:11:41
    do that on AWS so if you want to look at
  • 00:11:43
    how to do that just go back into my
  • 00:11:45
    video history and find that video I
  • 00:11:47
    really recommend doing that and they'll
  • 00:11:48
    even and you can even set up
  • 00:11:49
    notifications like you've hit 50% of
  • 00:11:52
    your budget and if your budget's $1 well
  • 00:11:55
    then you've you've hit 50 cents and if
  • 00:11:56
    you don't want to spend a dollar then
  • 00:11:58
    you need to
  • 00:12:00
    um you know you need to make sure that
  • 00:12:01
    you go in and cancel those uh or spin
  • 00:12:04
    down those servers before you hit that
  • 00:12:05
    so uh I think I've talked a lot to that
  • 00:12:08
    and I don't I think whoever's on don't
  • 00:12:10
    have any questions so I'm just going to
  • 00:12:11
    move on but uh yeah in tribe yep you can
  • 00:12:15
    definitely dockerize your uh you can
  • 00:12:20
    definitely dockerize your your services
  • 00:12:23
    so um there are the thing about Docker
  • 00:12:26
    is most of these big
  • 00:12:30
    providers these big cloud providers are
  • 00:12:32
    going to support a
  • 00:12:33
    Docker
  • 00:12:35
    container so if you container eyes using
  • 00:12:38
    Docker or whatever else the bigger
  • 00:12:39
    competitor is you'll definitely be able
  • 00:12:42
    to take whatever you've built and then
  • 00:12:45
    move it to any cloud provider and
  • 00:12:48
    they're like kubernetes the you know
  • 00:12:50
    orchestration the scaling uh
  • 00:12:53
    infrastructure and like AWS has one
  • 00:12:55
    that's kind of proprietary I think it's
  • 00:12:58
    ECS and and ECS is both for they support
  • 00:13:01
    a kuber kubernetes
  • 00:13:03
    u uh framework or just their own
  • 00:13:06
    whatever ECS is and they support Docker
  • 00:13:10
    so you can spin up different in scale
  • 00:13:14
    using dockerized containers and that
  • 00:13:16
    scalability that functionality there you
  • 00:13:19
    can use on probably any of these big
  • 00:13:22
    Services Red Hat Microsoft Amazon Google
  • 00:13:25
    they're all going to allow you to uh use
  • 00:13:27
    Docker so if you spend energy and put in
  • 00:13:32
    the uh the effort to dockerize your
  • 00:13:35
    Linux builds for uh your gdau back in
  • 00:13:38
    then you've opened up really quick and
  • 00:13:41
    easy way to deploy your Docker container
  • 00:13:43
    anywhere you can do your Docker testing
  • 00:13:46
    locally and you might even be able to
  • 00:13:48
    simulate resources locally now I haven't
  • 00:13:52
    used Docker in probably four or five
  • 00:13:54
    years uh but I was using it pretty
  • 00:13:57
    heavily before that so I have a lot of
  • 00:13:59
    experience with Docker and I don't know
  • 00:14:02
    if they had it back then but I have a
  • 00:14:04
    feeling that you you can tailor local
  • 00:14:06
    your local container uh to handle a
  • 00:14:10
    specific set of resources so you know
  • 00:14:12
    ebi that's another thing that I would
  • 00:14:14
    consider uh so good good point there on
  • 00:14:18
    tribe for that suggestion let's go to
  • 00:14:20
    AWS um which I don't have any comments I
  • 00:14:23
    guess somebody might have uploaded
  • 00:14:25
    something so I don't know why it's
  • 00:14:26
    showing a comment uh don't have anything
  • 00:14:28
    on Unity this week not really doing much
  • 00:14:32
    Unity at all lately maybe just answering
  • 00:14:33
    some
  • 00:14:35
    questions uh and uh we'll come back to
  • 00:14:37
    gdau let's go to Game Dev and just see
  • 00:14:40
    uh what what we've got here um so this
  • 00:14:43
    person's been using uh been running into
  • 00:14:46
    some problems with synchronization we we
  • 00:14:48
    we had a look at that last week um or
  • 00:14:50
    earlier this week I guess and we're I
  • 00:14:53
    think we were able to get them unstuck
  • 00:14:55
    for the most part I think they're having
  • 00:14:57
    problems with capturing the mouse not
  • 00:14:59
    exactly sure um so I'm going to just
  • 00:15:02
    gloss over that looking to make zate
  • 00:15:05
    it's been around for a while I'm going
  • 00:15:06
    to look at making customize customizable
  • 00:15:09
    characters and blender containing shape
  • 00:15:11
    Keys among other things I'm not too
  • 00:15:13
    familiar with you guys have any videos
  • 00:15:14
    recommended uh separate head and model
  • 00:15:15
    attaches the body certain IM not work
  • 00:15:18
    together separate meshes and
  • 00:15:20
    Gough um you know I don't have a ton of
  • 00:15:23
    experience with this stuff this is like
  • 00:15:24
    a different skill set the modeling side
  • 00:15:27
    of things
  • 00:15:29
    um you know in materials that's not my
  • 00:15:31
    expertise hopefully somebody hopefully
  • 00:15:33
    somebody's able to weigh in if you guys
  • 00:15:35
    know of any you know any answers to this
  • 00:15:38
    uh clothing yeah I I'm not I don't have
  • 00:15:41
    any experience with this stuff so I'm
  • 00:15:44
    not going to I'm not really going to
  • 00:15:46
    comment um I have a little bit of
  • 00:15:49
    experience
  • 00:15:52
    separating animations uh not actually
  • 00:15:55
    having a like the models the same like
  • 00:15:58
    the the you know obviously we have this
  • 00:16:00
    character model that I've been working
  • 00:16:02
    with or character models over the last
  • 00:16:03
    whatever year and you I I I have a uh a
  • 00:16:08
    video or something I did where I
  • 00:16:11
    separated the animations uh using an
  • 00:16:13
    animation tree where you could have an
  • 00:16:16
    animation State machine and separate out
  • 00:16:19
    like your running animation so if it was
  • 00:16:20
    pure running you would be running you
  • 00:16:22
    know you would see his arms move around
  • 00:16:24
    and that kind of thing but if he was
  • 00:16:25
    running with a gun then I have a state
  • 00:16:27
    that turns off like the top of the body
  • 00:16:30
    and it follows the mouse so he can like
  • 00:16:32
    aim up and down with that arm and it
  • 00:16:34
    tracks like with the mouse and so you
  • 00:16:37
    can run and do that at the same time so
  • 00:16:39
    you can actually see their like head
  • 00:16:40
    rotate Up and Down based on where they
  • 00:16:42
    were looking now that's one way you can
  • 00:16:44
    handle that but I think inverse
  • 00:16:46
    kinematics might be a
  • 00:16:50
    more better I want to say a better
  • 00:16:52
    approach in the long run but their stuff
  • 00:16:54
    uh gdau stuff was deprecated the time I
  • 00:16:56
    made those videos so I didn't want to
  • 00:16:57
    use a I wanted to find a different
  • 00:16:59
    solution for that so that's the only
  • 00:17:00
    thing I would say about that multiplayer
  • 00:17:02
    synchronizer emits on a button pressed
  • 00:17:04
    if that's your if that's your
  • 00:17:09
    flow I'm I'm not exactly sure I would do
  • 00:17:12
    it that way I would have to know a lot
  • 00:17:14
    more information and I think an RPC is a
  • 00:17:19
    better solution for that right because
  • 00:17:21
    rpcs are your event based rpcs are your
  • 00:17:24
    event-based
  • 00:17:26
    mechanisms um and your synchron is where
  • 00:17:29
    you want to synchronize and keep
  • 00:17:31
    something in sync at all times like
  • 00:17:32
    player health and and maybe positions
  • 00:17:35
    and that kind of thing so I'm not I'm
  • 00:17:37
    not sure if that's a good way to
  • 00:17:38
    approach that so consider using rpc's
  • 00:17:41
    Legion
  • 00:17:43
    um I I don't know what this enumeration
  • 00:17:47
    means I do not understand what they're
  • 00:17:49
    saying with
  • 00:17:50
    enumeration
  • 00:17:52
    um and yeah Scott scota doesn't really
  • 00:17:56
    do private messaging um
  • 00:18:01
    and I don't know what this video mean
  • 00:18:03
    rendering on dedicated server render
  • 00:18:05
    different players in different scenes so
  • 00:18:08
    that problem trying to
  • 00:18:10
    render different players in different
  • 00:18:14
    scenes
  • 00:18:16
    is uh I don't know how trivial that is I
  • 00:18:19
    talked about this the other day on at
  • 00:18:22
    some point or I I wrote about it in here
  • 00:18:24
    I can't exactly remember
  • 00:18:26
    but you can turn turn
  • 00:18:30
    off what you want to synchronize with
  • 00:18:32
    your synchronization or your multiplayer
  • 00:18:34
    synchronizer you can actually in I think
  • 00:18:37
    it's called visibility and you can
  • 00:18:40
    maybe so if you have a single server
  • 00:18:44
    that all your players are connecting to
  • 00:18:47
    and you're going to spawn a
  • 00:18:49
    scene you can probably do either a
  • 00:18:52
    custom spawn and only spawn it on a
  • 00:18:54
    specific node I think you might be able
  • 00:18:56
    to do that or you can spawn it and then
  • 00:19:00
    turn off visibility for X players or
  • 00:19:03
    turn it on for X players which however
  • 00:19:06
    way you want to handle that so I think I
  • 00:19:07
    think you can accomplish that it just it
  • 00:19:10
    might not be a super trivial thing I do
  • 00:19:12
    want to cover that I think I have a to
  • 00:19:15
    do in my uh list of videos future videos
  • 00:19:18
    where I want to cover this exact
  • 00:19:20
    scenario uh but it would be helpful to
  • 00:19:22
    know if you're if this is a persistent
  • 00:19:24
    world like a single world if it's a
  • 00:19:27
    Matchmaker world
  • 00:19:29
    where or if it's like a maybe like I I
  • 00:19:33
    know that someone was talking about this
  • 00:19:34
    the other day there was a game uh there
  • 00:19:37
    was a game
  • 00:19:38
    where um all the players would still be
  • 00:19:41
    there but you would be experiencing a
  • 00:19:42
    different scene and that's to me just
  • 00:19:45
    like a uh if it's even if it's a
  • 00:19:47
    temporary world it's still a persistent
  • 00:19:50
    world so I think that's uh something
  • 00:19:52
    that I'm I'm going to look into
  • 00:19:53
    eventually guys if you want uh there's a
  • 00:19:55
    making the
  • 00:19:57
    MMO um looks like they're using maybe a
  • 00:19:59
    python back end uh and connecting goob
  • 00:20:02
    to it I don't know I haven't seen it but
  • 00:20:03
    if you're interested join the Discord
  • 00:20:06
    and uh we've got some gurus and experts
  • 00:20:09
    in there and I try to get in there as
  • 00:20:11
    much as possible um a lot of times I get
  • 00:20:13
    really busy with work and other things
  • 00:20:15
    so I can't always get to it but let's
  • 00:20:17
    move on um okay so Annie's got a
  • 00:20:19
    question about a recent video I
  • 00:20:23
    did there's a moment where the player
  • 00:20:25
    name uh is set when a new player is
  • 00:20:28
    added to the game my issue is that the
  • 00:20:29
    player name solely depends on the new
  • 00:20:31
    network ID yep uh which is given by the
  • 00:20:33
    Callback uh what if I want to allow
  • 00:20:35
    players to decide their names I already
  • 00:20:37
    have a UI well then just make a
  • 00:20:40
    different field have a different name
  • 00:20:42
    field I mean that's uh that that's how I
  • 00:20:44
    would do that you wouldn't you keep the
  • 00:20:46
    name for your infrastructure I think
  • 00:20:48
    right now you you could use a different
  • 00:20:51
    field um if you watch go watch all of my
  • 00:20:55
    videos and you'll see that uh some of
  • 00:20:58
    them I use name some of them I use uh
  • 00:21:00
    player ID to represent network ID for
  • 00:21:04
    the checks that you need to do for
  • 00:21:06
    managing your multiplayer sessions and
  • 00:21:09
    and tracking you know where which pier
  • 00:21:11
    is where and should this pier uh have
  • 00:21:13
    access to certain things kind of like an
  • 00:21:15
    authority problem there so if if you're
  • 00:21:18
    confused about that uh I I think this is
  • 00:21:22
    how he would I think you can set name
  • 00:21:24
    here like that um if if let's see wrong
  • 00:21:27
    place set players name but how do I do
  • 00:21:29
    it probably found this U I don't know
  • 00:21:30
    why you wouldn't set it there
  • 00:21:35
    umie using synchronizer plays no play
  • 00:21:38
    you want to add a synct property such as
  • 00:21:39
    name and have it update only once yeah
  • 00:21:41
    so that's that's a pretty good answer I
  • 00:21:43
    think uh e Mario I think that's a pretty
  • 00:21:47
    good answer uh I don't see why you
  • 00:21:49
    wouldn't be able to set it there um I
  • 00:21:52
    don't see
  • 00:21:53
    why yeah just use a different field
  • 00:21:59
    um like in your
  • 00:22:04
    code you you can set it there or after
  • 00:22:09
    your player enters the
  • 00:22:13
    name or maybe uh have your
  • 00:22:17
    server send an RPC after they join or
  • 00:22:24
    connect that tells that uh that
  • 00:22:29
    informs or that sets the name sets the
  • 00:22:32
    name in all clients I like the idea of
  • 00:22:37
    syncing once when the player
  • 00:22:40
    spawns which is using your multiplayer
  • 00:22:44
    synchronizer uh Set Set uh check the
  • 00:22:50
    spawn
  • 00:22:51
    checkbox set sync to
  • 00:22:54
    never and that should do it so this is
  • 00:22:57
    good I like this answer spoiler it's got
  • 00:23:01
    annoying case uh you're using sockets I
  • 00:23:04
    haven't used sockets yet with good do
  • 00:23:07
    that is a little bit lower level um
  • 00:23:09
    haven't reached to that point I'm
  • 00:23:11
    covering everything high level right now
  • 00:23:13
    so as to allow for all the newer
  • 00:23:17
    developers to come in and not have to
  • 00:23:20
    worry about managing the messages
  • 00:23:21
    themselves and let's just rely on the
  • 00:23:23
    higher level apis for now uh eventually
  • 00:23:26
    if I can still do this channel for a
  • 00:23:29
    considerable amount of time I will go
  • 00:23:32
    and do more low lower level things uh
  • 00:23:34
    but we'll see everything's okay the code
  • 00:23:37
    is working except one case when the
  • 00:23:38
    server reloads and closes all
  • 00:23:40
    connections the D pulling proceeds to
  • 00:23:42
    show up and connection State
  • 00:23:43
    everything's okay well if you if the
  • 00:23:45
    server reloads and closes
  • 00:23:48
    connections I don't know what this is
  • 00:23:50
    this like a web socket you may have to
  • 00:23:54
    you may have to run through your reset
  • 00:23:58
    uh con
  • 00:23:59
    connection logic I I I'm not really
  • 00:24:02
    following this not sure let's see
  • 00:24:05
    uh Co working somewhere when server
  • 00:24:08
    reloads close all connections good
  • 00:24:09
    polling proceeds to show open connection
  • 00:24:11
    State as everything is okay I can't find
  • 00:24:13
    um yeah there should be I don't think I
  • 00:24:16
    don't know if anybody's replied to them
  • 00:24:18
    doesn't look like it I don't like to
  • 00:24:21
    double dip there has to be a call back I
  • 00:24:26
    I'm not sure if there's any
  • 00:24:30
    I would I would it would be very
  • 00:24:32
    unlikely if there wasn't a on disconnect
  • 00:24:34
    call back or some kind of mechanism
  • 00:24:37
    where you can hook into hey this
  • 00:24:39
    connection dropped uh that would be very
  • 00:24:41
    unlikely I I can't imagine there not
  • 00:24:43
    being that so I would I would think that
  • 00:24:45
    that's how they have to do that
  • 00:24:48
    um so I'm just going to respond to that
  • 00:24:50
    like that so let's see what Andy's got
  • 00:24:52
    thanks for the reply list of players
  • 00:24:55
    being shared across all peers sure um
  • 00:24:59
    you can send it that way or you can have
  • 00:25:03
    a dictionary that you
  • 00:25:05
    synchronize uh which will update a
  • 00:25:07
    players dictionary con all the players
  • 00:25:09
    yep which is to make it work in Steam
  • 00:25:12
    well I mean if if you're using the high
  • 00:25:15
    level apis in Steam it would work the
  • 00:25:18
    same way if you're going to use the
  • 00:25:19
    lower level apis and send messages
  • 00:25:21
    yourself then sure you'll have to uh you
  • 00:25:26
    know manage those things accordingly um
  • 00:25:29
    and you you if you're if you're like if
  • 00:25:32
    you're not using rpcs which is the high
  • 00:25:34
    level by the way if you didn't connect
  • 00:25:36
    those two
  • 00:25:37
    things if you're manually sending
  • 00:25:39
    messages in Steam using their other uh
  • 00:25:43
    gdau steam apis uh that are provided
  • 00:25:45
    then yeah you're going to have to
  • 00:25:47
    manually manage those synchronizations
  • 00:25:49
    um that way yeah so I'm just saying I'm
  • 00:25:53
    just going to repeat what I said that
  • 00:25:54
    you can synchronize a dictionary of the
  • 00:25:56
    players with some basic data uh don't
  • 00:25:59
    sync complex
  • 00:26:09
    objects like nodes or anything like that
  • 00:26:12
    just what you
  • 00:26:14
    need uh so you could do it that way or
  • 00:26:17
    you can sync uh you can send
  • 00:26:19
    rpcs um to keep a list of the the
  • 00:26:22
    players you can
  • 00:26:24
    also I I guess I guess I wouldn't do it
  • 00:26:27
    that way either but your clients can
  • 00:26:29
    also ask um every so often but then
  • 00:26:31
    that's why would you do that just when a
  • 00:26:34
    player joins or leaves you can always
  • 00:26:35
    just um send an RPC to everybody hey a
  • 00:26:39
    player left or hey a player joined and
  • 00:26:41
    you can always update everybody um
  • 00:26:44
    that's there that uh you know that needs
  • 00:26:47
    that information um and maybe not
  • 00:26:49
    everybody needs that information so yeah
  • 00:26:51
    using rpcs could work um it's probably
  • 00:26:54
    easier to do a sync but if you need to
  • 00:26:57
    have some
  • 00:26:58
    separations like team one or team two
  • 00:27:00
    kind of thing then yeah you can you can
  • 00:27:02
    definitely manage that manually more
  • 00:27:03
    with some
  • 00:27:05
    rpcs uh croy's got a question um I think
  • 00:27:09
    I said that right I don't know um if I'm
  • 00:27:10
    using multiplayer spawner for a player
  • 00:27:12
    character on the server multiplayer
  • 00:27:13
    author is being set however the client
  • 00:27:15
    multipay authority of the player is set
  • 00:27:17
    to one uh no um I I think the player
  • 00:27:21
    itself is the the player it if you're
  • 00:27:27
    let me just say hello first let me type
  • 00:27:29
    it out and then I'll review it just to
  • 00:27:32
    review let me find it really quick again
  • 00:27:35
    uh so on a server multiplayer Authority
  • 00:27:38
    is being set correctly um okay I'm not
  • 00:27:41
    exactly sure what that means I'm
  • 00:27:43
    guessing they are setting client
  • 00:27:45
    authority to that Pier however on the
  • 00:27:48
    client the multiplayer authority of the
  • 00:27:49
    player set to one that is correct so if
  • 00:27:51
    you are giving so I need a little bit
  • 00:27:53
    more information so if if you read my
  • 00:27:56
    reply
  • 00:27:58
    uh I'm I'm saying that if you set the
  • 00:28:02
    authority what you're going to set on
  • 00:28:03
    the server uh if you set that
  • 00:28:06
    Authority technically I'm not sure if it
  • 00:28:09
    is set in the server but whenever you
  • 00:28:11
    set it like on the enter tree function
  • 00:28:14
    or if you use the on ready uh approaches
  • 00:28:17
    I have a couple different approaches so
  • 00:28:18
    go watch my whole video series so you
  • 00:28:20
    can see the couple different ways I do
  • 00:28:21
    it but if you're setting the authority
  • 00:28:24
    to the local client which is going to be
  • 00:28:27
    the network ID right so some string of
  • 00:28:30
    eight numbers eight or nine characters
  • 00:28:31
    whatever it is
  • 00:28:33
    numbers if you just set the input so
  • 00:28:36
    that the players inputs keyboard and
  • 00:28:39
    mouse movements are client driven or
  • 00:28:42
    client the client has a sole source of
  • 00:28:44
    Truth so the client is telling the
  • 00:28:45
    server that so you're setting client
  • 00:28:46
    authority to input that's that case the
  • 00:28:49
    player object itself itself will still
  • 00:28:52
    be set to server Authority because what
  • 00:28:55
    that means is your setting the authority
  • 00:28:59
    over the inputs but it's your server who
  • 00:29:02
    determines where it should actually be
  • 00:29:05
    so if I teleport across the world
  • 00:29:09
    because I was able to input something
  • 00:29:12
    that was extraneous like in a racing
  • 00:29:14
    game somehow if I was able to send an
  • 00:29:17
    input that didn't make sense or
  • 00:29:20
    something and I was able to move across
  • 00:29:22
    the screen for example uh to the other
  • 00:29:24
    side of the world your server will still
  • 00:29:26
    have authority over that player be like
  • 00:29:28
    uhuh you can't teleport you can't do
  • 00:29:30
    that you can't cheat like that uh so
  • 00:29:32
    that's kind of a rough example of that
  • 00:29:35
    um so yeah I don't think that's a bug I
  • 00:29:37
    think that's correct your input should
  • 00:29:39
    not say one though your input should say
  • 00:29:42
    the the network ID of the of the player
  • 00:29:44
    so that's a good question uh can someone
  • 00:29:46
    help me tutorial for dedicate server for
  • 00:29:48
    Brack's game uh the dedicate Server
  • 00:29:50
    doesn't even start doesn't start even if
  • 00:29:52
    I add a ready function in the game man
  • 00:29:53
    scripts anybody know it could
  • 00:29:55
    be oh that's really vague um yeah I
  • 00:29:59
    think you're going to have to thanks
  • 00:30:01
    tribe I really think you're going to
  • 00:30:02
    have to post some stuff um he said
  • 00:30:05
    posting copy pasta and you posted it
  • 00:30:06
    here that's cool whatever it's not a big
  • 00:30:08
    deal
  • 00:30:10
    um let's see what we got here uh
  • 00:30:13
    dedicated server if OS feature are you
  • 00:30:16
    building it are are you building a
  • 00:30:17
    dedicated server
  • 00:30:20
    um did you select
  • 00:30:24
    the the dedicated
  • 00:30:29
    server option when building I have
  • 00:30:33
    definitely I that's not I'm not that's
  • 00:30:36
    not a dumb thing just to ask because
  • 00:30:39
    I've definitely done that I've I've
  • 00:30:41
    built a game before and I went to deploy
  • 00:30:45
    it and it just puked it didn't know I it
  • 00:30:47
    just didn't make any sense and then I
  • 00:30:49
    went back and realized that I actually
  • 00:30:51
    just made a build of the game and not
  • 00:30:52
    dedicated server uh so of course the
  • 00:30:55
    feature would not be there and I I see
  • 00:30:58
    what they're saying so what's happening
  • 00:30:59
    is they're they're the game they're
  • 00:31:03
    trying to do a dedicated server build
  • 00:31:05
    and they're saying it's not starting um
  • 00:31:07
    it's likely that they just built a
  • 00:31:08
    client build and not a dedicated server
  • 00:31:10
    build so that that does happen um I'm
  • 00:31:13
    going to need some more information uh
  • 00:31:16
    uh we'll do thanks um we'll do uh join
  • 00:31:21
    the tester
  • 00:31:23
    Squad under
  • 00:31:25
    roles I do test
  • 00:31:30
    uh from time to
  • 00:31:32
    time well that's for me I mean I don't
  • 00:31:35
    know other people can do that too
  • 00:31:36
    anyways so anyone familiar with
  • 00:31:38
    microphone nah no I am not uh trying to
  • 00:31:41
    get the volume output my code is
  • 00:31:42
    detecting the Spectrum analizer and
  • 00:31:44
    returns um I'm going to just do a h not
  • 00:31:47
    sure here uh and a thinky face because I
  • 00:31:51
    don't know but I'm still going to look
  • 00:31:54
    at their code because I'm curious so
  • 00:31:55
    they've got a ready function
  • 00:31:58
    trying to get the volume output my code
  • 00:31:59
    is techic Spectrum analer I think but
  • 00:32:01
    only return Zer Z when I attempt to get
  • 00:32:02
    the frequency this is a cool problem a
  • 00:32:05
    very cool problem I don't really know
  • 00:32:06
    much so um if analyzer if they have an
  • 00:32:10
    analyzer instance here uh they're
  • 00:32:13
    getting the magnitude for frequency so
  • 00:32:15
    they're getting the uh a magnitude for a
  • 00:32:17
    range of frequency and it's just not
  • 00:32:20
    printing uh return Z 0 so yeah it it you
  • 00:32:25
    know I'm not sure I this sounds like a
  • 00:32:27
    really cool problem though uh they have
  • 00:32:29
    their analyzer instance
  • 00:32:32
    um um yeah so not sure there all right
  • 00:32:35
    so I think we've got through this and uh
  • 00:32:37
    I'm gonna switch over to YouTube because
  • 00:32:40
    I think we've got everybody kind of
  • 00:32:43
    straightened out here Legion yeah man
  • 00:32:45
    we're g to need some more info to help
  • 00:32:46
    you out
  • 00:32:47
    there um let's start the old video so
  • 00:32:50
    six days ago so I haven't checked in on
  • 00:32:52
    things in a while I have a question some
  • 00:32:54
    have you ever tried W4 we were just
  • 00:32:55
    talking about W4 uh how do do you think
  • 00:32:58
    worth it to use is better option for
  • 00:32:59
    multi honestly confused multiplayer
  • 00:33:01
    theme I'm going to plumish my game on
  • 00:33:02
    Steam maybe there's better option uh
  • 00:33:04
    yeah so you can do that you can do all
  • 00:33:08
    that stuff
  • 00:33:09
    um I just checked on some stuff with W4
  • 00:33:15
    and I am really excited
  • 00:33:18
    because I come from a background with uh
  • 00:33:21
    using um you know AWS and and and
  • 00:33:24
    gamelift so I've used unity's multiplay
  • 00:33:28
    I didn't get terribly deep into it
  • 00:33:30
    because it was new and then the unity
  • 00:33:31
    thing happened and then I switched to
  • 00:33:32
    gdau but it's uh it looks like you can
  • 00:33:36
    get an $800 credit so if you're into
  • 00:33:39
    Unity check it out and I've used it it's
  • 00:33:42
    really cool they have matchmaking they
  • 00:33:44
    have
  • 00:33:45
    scalability the matchmaking rules seem
  • 00:33:48
    really customizable for whatever you're
  • 00:33:51
    trying to do they allow you to create
  • 00:33:54
    Unity builds and upload those builds and
  • 00:33:57
    have you know they they will store your
  • 00:33:59
    Builds on the server and then you can
  • 00:34:01
    scale up to support your your matches or
  • 00:34:04
    your game to you know host whatever
  • 00:34:07
    backend uh you need to do with
  • 00:34:09
    unity uh I believe they also offer some
  • 00:34:13
    they uh at the time they didn't have
  • 00:34:15
    certain things but I think they were
  • 00:34:17
    going to offer
  • 00:34:20
    additional like database
  • 00:34:23
    storing let's see what else did they
  • 00:34:27
    what what else they offer anyways I
  • 00:34:29
    whatever they offered a bunch of support
  • 00:34:31
    for things that you would need if you
  • 00:34:33
    were a game developer and I think they
  • 00:34:35
    were only going to grow and at the time
  • 00:34:37
    they were still working through some of
  • 00:34:39
    the stuff but the bottom line is you can
  • 00:34:41
    host your backend game server there and
  • 00:34:42
    you can scale it and you can create a
  • 00:34:45
    Matchmaker uh and leverage that and if
  • 00:34:49
    you don't want to get into building your
  • 00:34:51
    own cloud infrastructure it was it it's
  • 00:34:55
    a really cool thing like if you don't
  • 00:34:56
    care about learning aw us and you don't
  • 00:34:58
    want to deal with the permissions and
  • 00:35:00
    all that stuff because there's a lot
  • 00:35:01
    involved with it oh authentication and
  • 00:35:03
    user authentication and and I I think
  • 00:35:05
    they were offering that as well if you
  • 00:35:07
    don't want to get into all that yourself
  • 00:35:08
    and manage that which I totally get
  • 00:35:11
    because there's a lot involved it's
  • 00:35:12
    really hard for a beginner to come into
  • 00:35:14
    you know a
  • 00:35:16
    multiplayer game and that kind of thing
  • 00:35:18
    and then be able
  • 00:35:20
    to get into cloud and become and and
  • 00:35:23
    have all those like gut instincts about
  • 00:35:25
    where you need to watch out for security
  • 00:35:27
    thing and that sort of
  • 00:35:29
    thing there's just a lot to it and for a
  • 00:35:31
    beginner it's a little daunting to do an
  • 00:35:33
    AWS to do a Google red hat and that kind
  • 00:35:35
    of thing now they do have products that
  • 00:35:37
    are that really lower the barrier to
  • 00:35:38
    entry and I don't want to steer anybody
  • 00:35:41
    away from it because if you spend enough
  • 00:35:43
    time you will get it like if yeah it's
  • 00:35:45
    going to seem overwhelming and weird and
  • 00:35:48
    confusing at first uh I have a few
  • 00:35:50
    videos to hopefully make it a little bit
  • 00:35:53
    more approachable um and then some of my
  • 00:35:55
    videos aren't really for the beginning
  • 00:35:57
    it might be for somebody that does have
  • 00:35:59
    a AWS experience but just wants to learn
  • 00:36:01
    more and I think a lot of my older Unity
  • 00:36:04
    videos were based on cloud um Cloud
  • 00:36:08
    products like gamelift and uh and that
  • 00:36:10
    kind of thing we're more geared towards
  • 00:36:12
    the more advanc user but some of the
  • 00:36:15
    stuff I have on there like Lambda
  • 00:36:16
    functions and Dynamo DB which is you
  • 00:36:18
    know a really cool nosql database which
  • 00:36:21
    I'm I'm going to do more videos on
  • 00:36:23
    because I'm getting a lot of questions
  • 00:36:24
    about how to store stuff and dynamoe EV
  • 00:36:26
    is amazing and it's super cheap if not
  • 00:36:27
    just free like for a really long time so
  • 00:36:30
    I'm going to do some more on that and
  • 00:36:32
    now that this I've gone off on this
  • 00:36:34
    tangent about working with unity
  • 00:36:37
    W4 is going to do the same thing and
  • 00:36:40
    that's why I said all that is because I
  • 00:36:42
    have experienced I've worked with all
  • 00:36:44
    those products uh game lift and and and
  • 00:36:48
    whatever this and whatever unity's
  • 00:36:49
    version of
  • 00:36:51
    now W4 is going to be doing that they're
  • 00:36:55
    going to be offering cloudbased uh
  • 00:36:58
    database uh authentication and I don't
  • 00:37:00
    know exactly how they're going to do the
  • 00:37:02
    auth authentication I don't know if
  • 00:37:04
    they're just going to hook into generic
  • 00:37:05
    oo stuff or they're going to like manage
  • 00:37:07
    your users for you um like in AWS you
  • 00:37:12
    can have a a Cognito server or Cognito
  • 00:37:16
    instance and have all your you know your
  • 00:37:18
    users there and you can do your you can
  • 00:37:20
    add authentication through that um so I
  • 00:37:25
    don't exactly know how their apis are
  • 00:37:26
    going to be set up uh but but they're
  • 00:37:27
    going to do scaling uh deploying your
  • 00:37:29
    servers so to get back to this they're
  • 00:37:33
    still in beta so they're not ready to go
  • 00:37:36
    yet uh I think that yeah I I think that
  • 00:37:40
    gdau is still like going through the
  • 00:37:42
    growing paines now if you know anything
  • 00:37:43
    about Linux servers I mean you can just
  • 00:37:45
    start with any cloud service like I
  • 00:37:47
    talked about at the beginning of the
  • 00:37:48
    stream you can use AWS and just manage
  • 00:37:50
    your own cluster and scale your backend
  • 00:37:53
    accordingly as as you need to um if you
  • 00:37:56
    put your game on
  • 00:37:58
    Steam all that all steam is doing is
  • 00:38:03
    let's just separate this out for a
  • 00:38:04
    second so there's steam listing and then
  • 00:38:07
    steam multiplayer steam listing is
  • 00:38:10
    you're just listing your game to be
  • 00:38:12
    available on Steam so think single
  • 00:38:14
    player game you download the game you
  • 00:38:16
    play the game and it's it's
  • 00:38:18
    authenticated through your Steam account
  • 00:38:20
    so you have a a way to track legitimate
  • 00:38:23
    purchases that's your steam listing now
  • 00:38:26
    steam multiplayer is
  • 00:38:28
    P2P
  • 00:38:30
    so you may not want a P2P game now I
  • 00:38:33
    know that steam offers
  • 00:38:36
    dedicated server or Anonymous hosting
  • 00:38:39
    with their steam I have not played
  • 00:38:42
    around with that yet I not I do not have
  • 00:38:44
    experience with that yet but I know that
  • 00:38:45
    those things are available so in theory
  • 00:38:48
    you can use a dedicated server setup uh
  • 00:38:51
    with steam I haven't played around with
  • 00:38:53
    it so you can list your game on Steam
  • 00:38:57
    and then use AWS to host your games back
  • 00:39:00
    in because your game client can
  • 00:39:03
    authenticate in Steam and then you can
  • 00:39:06
    probably I I know you can authenticate
  • 00:39:08
    using uh steam through gdau Steam so if
  • 00:39:11
    you want to add gdau steam to your your
  • 00:39:14
    gdau game which you will if you're going
  • 00:39:16
    to list it on Steam uh your back end can
  • 00:39:18
    use that steam credentials and
  • 00:39:20
    authenticate to make sure that the calls
  • 00:39:23
    or the API calls or to establish those
  • 00:39:25
    connections are uh
  • 00:39:27
    authorized using that steam client and
  • 00:39:30
    those credentials uh back to your games
  • 00:39:32
    back in regardless of where it's hosted
  • 00:39:35
    so it can be hosted on AWS or anything
  • 00:39:37
    like that so that was quite a bit um so
  • 00:39:40
    I'm I'm gonna be like referred I'm going
  • 00:39:42
    to publish the stream and I'll be like
  • 00:39:43
    refer to this stream um W4 games I I
  • 00:39:48
    mean definitely check them out I'm going
  • 00:39:50
    to check them out soon uh I think we're
  • 00:39:52
    going to maybe do a little collab or
  • 00:39:53
    maybe I'll just do a tutorial on it and
  • 00:39:56
    see where they're at I got to talk to
  • 00:39:57
    them some more I'm in talks with them
  • 00:39:58
    now a little bit um and they seem like
  • 00:40:01
    it's promising I'm really excited about
  • 00:40:04
    it I I think they're still kind of
  • 00:40:05
    working through the pricing a little bit
  • 00:40:07
    uh hopefully we see a pretty generous
  • 00:40:09
    free tier um but yeah I um I think W4
  • 00:40:13
    can be really good but you may want to
  • 00:40:16
    start just hosting it somewhere else uh
  • 00:40:19
    like on one of those Cloud providers and
  • 00:40:21
    if you join our Discord I'm going to put
  • 00:40:23
    a list of servers I'm actually going to
  • 00:40:25
    write a note so I don't forget so drop
  • 00:40:27
    by the server if you uh Discord server
  • 00:40:29
    if you want to see a more comprehensive
  • 00:40:30
    list of of uh resources there so I
  • 00:40:32
    really like your tutorials wonder if you
  • 00:40:34
    can help me start ship bridge game not
  • 00:40:36
    sure what that means trying to figure
  • 00:40:38
    out how to have multiple players for
  • 00:40:40
    different for
  • 00:40:41
    each different PCS each yeah again this
  • 00:40:45
    goes back to that okay I have a multip
  • 00:40:48
    backend or I have an instance that I
  • 00:40:50
    want to spawn of different players into
  • 00:40:53
    different scenes I don't have a solution
  • 00:40:56
    off the top of my head head for that I'm
  • 00:40:58
    going to have to come back to this I I I
  • 00:41:01
    have I've had enough requests for this
  • 00:41:03
    to do a video so I'm I'm really I'm
  • 00:41:08
    going to refer back to what I said
  • 00:41:10
    before is I think you can use the
  • 00:41:11
    spawner and the visibility tools to to
  • 00:41:15
    tackle this but I plan on doing a video
  • 00:41:17
    on it I actually answered this question
  • 00:41:20
    somewhere and I provided a feedback for
  • 00:41:23
    it already um I will try to provide more
  • 00:41:27
    information for that later so hopefully
  • 00:41:30
    hopefully I can find something on that
  • 00:41:32
    um but again I think that's going to
  • 00:41:34
    require a little bit
  • 00:41:36
    of you know massage and and shimming
  • 00:41:39
    some things into place I I have I don't
  • 00:41:42
    know I'm definitely going to I'm that's
  • 00:41:44
    in the queue I'm going to do a video on
  • 00:41:46
    that so I just don't know when so I've
  • 00:41:48
    got a lot more right now to work through
  • 00:41:50
    so we'll see if I can get to that um uh
  • 00:41:53
    sooner than later now I hope to see your
  • 00:41:56
    paid content on sites like you did me a
  • 00:41:57
    I don't have any paid content I
  • 00:42:00
    everything is on YouTube uh the patreon
  • 00:42:03
    stuff I had listed some projects on
  • 00:42:06
    there but I haven't listed for a while I
  • 00:42:10
    I you need a machine translation
  • 00:42:12
    function that okay so this is cool this
  • 00:42:15
    is new I I'm not really familiar with
  • 00:42:17
    that and I didn't know that there was a
  • 00:42:19
    demand for that so I'm I I wonder if I
  • 00:42:23
    can still offer it for
  • 00:42:25
    free but then
  • 00:42:28
    like just sticking on patreon uh I'll
  • 00:42:30
    have to look into that yeah you know
  • 00:42:32
    help me out if you have any more
  • 00:42:33
    information because uh any kind of any
  • 00:42:36
    kind of help with like that that could
  • 00:42:38
    speed up my research would be greatly uh
  • 00:42:41
    would be greatly appreciated and thanks
  • 00:42:43
    for uh thanks for watching that this is
  • 00:42:44
    the best Kau tutor multipor I've ever
  • 00:42:47
    seen um thanks for the video uh when I
  • 00:42:50
    join as a host the camera is jittering
  • 00:42:51
    um cameras enabled position smoothing
  • 00:42:54
    five pictures per second is there a
  • 00:42:55
    solution cameras enabled of position
  • 00:42:58
    smoothing with five pixels per second
  • 00:43:00
    not really sure what he means
  • 00:43:03
    there camera is enabled of position
  • 00:43:06
    smoothing with five pixels a
  • 00:43:08
    second are are they
  • 00:43:11
    synchronizing yeah sometimes your camera
  • 00:43:14
    will Jitter if you have it set up and I
  • 00:43:17
    I've experienced this if you have it set
  • 00:43:19
    up in a certain way I don't know I can't
  • 00:43:21
    really detail that right now off the top
  • 00:43:23
    of my head but I know there's a like
  • 00:43:25
    especially in 3D worlds if your camera
  • 00:43:28
    is nested um and maybe you don't have
  • 00:43:30
    like a spring arm or something you could
  • 00:43:32
    end up with some Jitters I've I've been
  • 00:43:35
    able to get away with some of that I
  • 00:43:36
    think by moving the by um I still put
  • 00:43:40
    the camera underneath the player in my
  • 00:43:41
    latest videos like especially this one
  • 00:43:43
    this gdau 3D uh template that I've been
  • 00:43:45
    working on and some of my older gdau 3D
  • 00:43:48
    stuff but uh and yeah I have notic some
  • 00:43:51
    Jitters and over time I feel like I'm
  • 00:43:54
    getting better at it and I'm not really
  • 00:43:55
    sure exactly what I did to get better at
  • 00:43:57
    it maybe um you know I've added a spring
  • 00:44:00
    arm I've added a sphere around the
  • 00:44:03
    camera the Collision Sphere for the
  • 00:44:06
    camera um and I I don't really
  • 00:44:08
    experience it uh as much so um you know
  • 00:44:12
    synchronization if you're synchronizing
  • 00:44:14
    there another issue is Authority like
  • 00:44:17
    maybe you're synchronizing the camera
  • 00:44:19
    and you don't have it to set to client
  • 00:44:21
    Authority maybe your server is fighting
  • 00:44:22
    it that would be an extreme case I
  • 00:44:24
    probably I don't think it's that but
  • 00:44:26
    yeah again get back to me on that one
  • 00:44:29
    I'm not exactly sure what to what to say
  • 00:44:31
    with that um great tutorial wow well
  • 00:44:34
    okay so these making the this whole
  • 00:44:36
    making a gdau 3D uh so this playlist
  • 00:44:40
    that I'm going through right now with uh
  • 00:44:43
    making the video game I'm hesitating to
  • 00:44:46
    call it a tutorial because I'm not
  • 00:44:50
    really showing you guys how to do
  • 00:44:53
    anything I'm showing you how I develop
  • 00:44:56
    or how I struggle through these things
  • 00:44:58
    and uh I'm I'm trying new things I'm
  • 00:45:04
    experimenting going through the motions
  • 00:45:06
    of development and and banging my head
  • 00:45:07
    against it I I'm not able to work on it
  • 00:45:10
    every day so I I'm struggling a little
  • 00:45:12
    bit more like my last stream that I just
  • 00:45:15
    wrapped up last week to this week I
  • 00:45:19
    forgot that I had broke something and
  • 00:45:22
    and needed to fix it still so when I
  • 00:45:24
    jumped into the latest stream uh which
  • 00:45:26
    will probably be out next week uh I I
  • 00:45:29
    had some problems I think I'll cut it
  • 00:45:30
    down in editing so it won't be as
  • 00:45:32
    obvious but if you were on the stream
  • 00:45:34
    yeah it was it was a little difficult so
  • 00:45:36
    it's not really a tutorial it's just
  • 00:45:38
    kind of me going through it and banging
  • 00:45:40
    my head against it you can call it a
  • 00:45:42
    tutorial for better lack of word I guess
  • 00:45:44
    what maybe it's a a live Dev stream cool
  • 00:45:48
    uh thank you for appreciating it I
  • 00:45:52
    appreciate you watching it and um I'm
  • 00:45:54
    excited that there are people that are
  • 00:45:57
    interested in seeing that um I I'm kind
  • 00:46:00
    of in a mode where I'm super busy with
  • 00:46:02
    some stuff uh with some other
  • 00:46:03
    responsibilities outside of the channel
  • 00:46:05
    so I'm not able to do full tutorials
  • 00:46:07
    right now but like I mentioned before
  • 00:46:09
    there are some things I do have in the
  • 00:46:11
    queue like W4 and multiplayer scenes and
  • 00:46:14
    splitting those things up and that sort
  • 00:46:15
    of thing that I want and even GD sync I
  • 00:46:17
    want to get to um and uh I can only do
  • 00:46:20
    so much a day so thanks for watching uh
  • 00:46:23
    but you're saying you're interested in
  • 00:46:24
    creating a P2P multiplayer game over the
  • 00:46:25
    internet as as possible that one hosts
  • 00:46:27
    the game and the PC provides the IP port
  • 00:46:30
    of the Matchmaker like you showed your
  • 00:46:31
    ads or you need a dedicated server
  • 00:46:33
    always yes uh it is absolutely possible
  • 00:46:37
    steam will do this out of the box for
  • 00:46:40
    you so if you want to use steam they
  • 00:46:44
    will they will allow you to you can use
  • 00:46:47
    steam's P2P you can use the highle steam
  • 00:46:50
    P2P apis uh this video right here is one
  • 00:46:53
    I think this uses the Standalone Uh
  • 00:46:56
    custom build of gdau which I wouldn't
  • 00:46:58
    really recommend using I would stick
  • 00:47:00
    with the I'm just seeing if I have it up
  • 00:47:02
    already I would stick with the other
  • 00:47:05
    steam version where it using an
  • 00:47:07
    extension I think that's a little bit
  • 00:47:09
    more promising um and the developer is
  • 00:47:11
    actively developing that I think they're
  • 00:47:13
    both developers are maintaining them but
  • 00:47:15
    I just like the extension version rather
  • 00:47:17
    than using a custom gdau version that
  • 00:47:18
    just kind of smells a little funky with
  • 00:47:20
    in terms of long-term
  • 00:47:22
    management um but cool yeah I I think
  • 00:47:26
    you can definitely do that with P2P uh
  • 00:47:28
    there are ways to do it without steam so
  • 00:47:32
    what you can do here is you can create a
  • 00:47:35
    Matchmaker and you can have a relay that
  • 00:47:39
    you host in AWS you can probably do that
  • 00:47:42
    through like a Lambda function just like
  • 00:47:44
    what whatever you're referring to I
  • 00:47:45
    believe you're referring to my
  • 00:47:46
    matchmaker Series so yeah if you're
  • 00:47:48
    interested to go check that out um you
  • 00:47:50
    don't always need a dedicated server but
  • 00:47:52
    you need a relay server which like I
  • 00:47:54
    just said could be like a Lambda
  • 00:47:56
    function
  • 00:47:57
    W4 uh GD sync
  • 00:48:01
    and um some of the other services I
  • 00:48:04
    can't remember top of my head do provide
  • 00:48:05
    you PDP
  • 00:48:07
    matchmaking uh there's another big AAU
  • 00:48:09
    one I I keep forgetting it but um they
  • 00:48:12
    they will provide you those relay
  • 00:48:14
    services and they allow you to connect
  • 00:48:16
    P2P and run that kind of thing I'm going
  • 00:48:19
    to do a video on GD sync I believe in
  • 00:48:22
    the next couple months I hope hopefully
  • 00:48:24
    I can get to it uh once I get through
  • 00:48:27
    this multiplayer template and I get to a
  • 00:48:29
    stopping point then I'm going to try to
  • 00:48:31
    focus on some more tutorial based videos
  • 00:48:34
    um and at that point I will probably
  • 00:48:35
    give you a solution to this using GD
  • 00:48:37
    sync again you can use steam you can
  • 00:48:40
    also
  • 00:48:41
    use uh like a Nat punch through I think
  • 00:48:44
    is the name
  • 00:48:47
    netfox uh offers that through this
  • 00:48:51
    product called nor and he's actually
  • 00:48:54
    hosting a relay server for super cheap
  • 00:48:56
    so take advantage of it while you while
  • 00:48:58
    you can while it's out there for testing
  • 00:49:00
    uh he's done a fork of something and um
  • 00:49:04
    let's see nap punch through is not
  • 00:49:07
    always a viable option so if you want
  • 00:49:10
    read up about what nap punch through is
  • 00:49:12
    I I do have some resources on that that
  • 00:49:15
    I can also share and if you're
  • 00:49:17
    interested read up on that but uh
  • 00:49:19
    they're they're basically saying if you
  • 00:49:20
    can't do that um that he's he has a
  • 00:49:24
    different uh solution and I'm not
  • 00:49:26
    exactly sure what it's doing behind the
  • 00:49:28
    scenes uh you can read up on more there
  • 00:49:31
    nap punch through Alternatives um I can
  • 00:49:33
    try to post some followup answers for
  • 00:49:36
    this uh and with some links if I can
  • 00:49:38
    find it but yeah you can definitely do
  • 00:49:40
    it that way um and I believe what you'll
  • 00:49:42
    do is um there's two ways you can
  • 00:49:46
    approach it off the top of my head where
  • 00:49:50
    if you want a player connect directly to
  • 00:49:53
    your
  • 00:49:55
    computer I I know if I would recommend
  • 00:49:57
    doing this for like a
  • 00:49:59
    production like you're having strangers
  • 00:50:01
    connect to your computer I don't know
  • 00:50:04
    that just seems a little insecure uh I I
  • 00:50:08
    I guess you could do it if you if you
  • 00:50:10
    knew you were playing with your friends
  • 00:50:11
    or maybe that is common I'm not terribly
  • 00:50:15
    familiar with that setup because of that
  • 00:50:18
    like weird like I'm a little sked out by
  • 00:50:19
    having people to corre connect directly
  • 00:50:21
    my to my computer but if you were
  • 00:50:23
    playing with friends you didn't care or
  • 00:50:26
    you were planning on just playing with a
  • 00:50:28
    small group of friends or a small group
  • 00:50:30
    uh small set of people and in this you
  • 00:50:32
    know you didn't really care and you were
  • 00:50:34
    telling people hey we're going to
  • 00:50:36
    connect directly to your computer you
  • 00:50:38
    would have to open the port on your
  • 00:50:40
    router so that those people can connect
  • 00:50:43
    to the game running on your local PC and
  • 00:50:46
    then you would probably have to forward
  • 00:50:48
    that Port I think back to your computer
  • 00:50:51
    I think maybe not maybe that can be
  • 00:50:54
    handled directly it depends uh on your
  • 00:50:56
    router and your computer's configuration
  • 00:50:58
    your firewalls configuration and that
  • 00:51:00
    kind of thing and your even your IP or
  • 00:51:02
    your um internet provider they they may
  • 00:51:05
    even have some weird restrictions on all
  • 00:51:06
    that hopefully you live in a re a region
  • 00:51:09
    where they don't do that but anyways
  • 00:51:11
    what other companies are doing is there
  • 00:51:13
    uh so I guess the way just to finish
  • 00:51:15
    that up is like the way that would work
  • 00:51:17
    is I think you could have like a relay
  • 00:51:18
    server where you connect to like refer
  • 00:51:21
    like like what I did with this AWS thing
  • 00:51:23
    where you have like a Matchmaker like
  • 00:51:25
    relay Server Like A that a Lambda
  • 00:51:27
    function that just spins up when you
  • 00:51:28
    need it super low cost of any cost at
  • 00:51:31
    all have your clients connect to that
  • 00:51:35
    and then once you have let's say you
  • 00:51:36
    have four people 2v2
  • 00:51:38
    match or um and then like one guy's a
  • 00:51:41
    host like one guy's marked as a host so
  • 00:51:43
    he's he created the match right so he
  • 00:51:46
    would make a call to that Lambda
  • 00:51:48
    function uh the Lambda would uh would
  • 00:51:50
    run and it would you you could do like a
  • 00:51:53
    websocket approach like what I did in
  • 00:51:55
    that video and he can be marked as the
  • 00:51:57
    host and then what you can do is once
  • 00:52:02
    you have everybody in the match
  • 00:52:04
    connected and ready to go and the game
  • 00:52:06
    is ready to start you could send them
  • 00:52:09
    your IP address and they you can just
  • 00:52:12
    send like a a request to okay everybody
  • 00:52:15
    connect to that person's IP address and
  • 00:52:17
    they would all connect to your IP
  • 00:52:18
    address now I I don't think it's as
  • 00:52:20
    simple as that I think there are
  • 00:52:22
    other technical things that I just
  • 00:52:25
    talked about that you may have to do to
  • 00:52:28
    allow people to connect back to your
  • 00:52:30
    server I don't want to talk to that off
  • 00:52:31
    the top of my head because I haven't
  • 00:52:34
    done a whole lot of work on that I have
  • 00:52:36
    done research in the past and like I
  • 00:52:37
    said there are some other ways to do
  • 00:52:38
    that but you can look into that so
  • 00:52:41
    that's like one column and then the
  • 00:52:43
    another solution that I know off the top
  • 00:52:45
    of my head is a relay server so I
  • 00:52:48
    believe that's what like norray is doing
  • 00:52:51
    uh for netfox and um there's this is
  • 00:52:54
    what a lot of the
  • 00:52:56
    cloud services are offering where you do
  • 00:52:59
    have like a Matchmaker just like you
  • 00:53:01
    know like I did with my AWS thing but
  • 00:53:05
    instead of you giving out your IP
  • 00:53:09
    address they just have a server with
  • 00:53:11
    your game backend running right so
  • 00:53:14
    there's like kind of two architecture
  • 00:53:17
    components here there's like your
  • 00:53:18
    Matchmaker thing and that lives in its
  • 00:53:19
    own thing and then I mean it can be on
  • 00:53:22
    the same server but it's cheaper to just
  • 00:53:24
    do it as a Lambda function uh or a
  • 00:53:26
    server Lambda is AWS product for like a
  • 00:53:29
    serverless server so it just like only
  • 00:53:31
    runs when you need it um and then you'll
  • 00:53:33
    have your game server hosted somewhere
  • 00:53:35
    else um it can be on a whole other cloud
  • 00:53:38
    service or it can be on AWS or wherever
  • 00:53:41
    and all it acts as is is a relay server
  • 00:53:44
    so all your clients are still playing
  • 00:53:47
    P2P but you have a relay server where
  • 00:53:50
    all the connections and commands and
  • 00:53:52
    data transfer relay are relayed through
  • 00:53:55
    so nobody knows knows anybody's IP
  • 00:53:57
    address you can probably do this
  • 00:54:00
    yourself and have a you know a
  • 00:54:02
    standalone or a relay that everybody
  • 00:54:04
    connects to and runs the game that way
  • 00:54:08
    and it's technically I guess PTP because
  • 00:54:11
    you're still you know connecting to
  • 00:54:14
    other people's uh maybe one player is
  • 00:54:18
    like the game server and you're just
  • 00:54:19
    using this as a relay so that you hide
  • 00:54:22
    those IP addresses and I think maybe
  • 00:54:25
    what I said was a little confus using
  • 00:54:26
    cuz it sounded like I I did say that
  • 00:54:29
    your game server would be hosted in
  • 00:54:31
    relay but that's not accurate I think
  • 00:54:33
    what would happen is the game itself
  • 00:54:36
    would assign one of the people as like
  • 00:54:38
    the host or uh this you know the true
  • 00:54:41
    Authority and then the relay is just
  • 00:54:43
    like a relay for the data that gets
  • 00:54:45
    passed back and forth now that's a
  • 00:54:47
    little technical uh I don't know off the
  • 00:54:49
    top of my head anybody that's doing that
  • 00:54:51
    I mean I mean I know GD sync and W4 I
  • 00:54:53
    think and several other people are going
  • 00:54:55
    to provide that service but if you want
  • 00:54:56
    to do it yourself I'm sure there's
  • 00:54:59
    probably 10 different implementations on
  • 00:55:00
    the internet on how to run relay servers
  • 00:55:03
    for P2P games and I don't think you need
  • 00:55:05
    to have to you're not g to you're not
  • 00:55:07
    going to be locked into gdau or anything
  • 00:55:09
    you could probably make a python server
  • 00:55:10
    or a node server and just have everybody
  • 00:55:12
    connect to that and you somehow have to
  • 00:55:15
    figure out how to Mark somebody as the
  • 00:55:17
    host and make them be the you know the
  • 00:55:20
    source of Truth for that so off the top
  • 00:55:22
    of my head I don't know exactly how to
  • 00:55:23
    do that but definitely look into that
  • 00:55:25
    and I'm probably going to link to the
  • 00:55:27
    stream to this person so they have an
  • 00:55:28
    idea of where to go instead of leaving a
  • 00:55:30
    lengthy comment uh great so let me go
  • 00:55:35
    here uh hey so I tried it out mostly
  • 00:55:37
    work okay so they done the problem is
  • 00:55:38
    when testing three more players second
  • 00:55:40
    player will not work for third player
  • 00:55:41
    basically players will not be able to
  • 00:55:42
    see the movements other players who join
  • 00:55:44
    how do you fix this
  • 00:55:47
    uh this sounds like an authority
  • 00:55:50
    problem um anytime that you don't have
  • 00:55:57
    X player seeing X thing from another
  • 00:56:00
    player is like an authority problem um
  • 00:56:04
    where your
  • 00:56:05
    synchronizer either isn't set up
  • 00:56:08
    correctly or your inputs aren't set up
  • 00:56:10
    correctly and you're not cor you're uh
  • 00:56:14
    you're not you know those POs the
  • 00:56:17
    positions of the movements are the the
  • 00:56:19
    the property the position properties and
  • 00:56:21
    getting synced uh
  • 00:56:23
    correctly yeah I'm going to need a
  • 00:56:25
    little bit more information
  • 00:56:26
    because this is a common problem I run
  • 00:56:29
    into this problem if you've watched my
  • 00:56:31
    stream on this making a gdo 3D
  • 00:56:34
    multiplayer template I've ran into that
  • 00:56:36
    problem and I fixed it and it's it's
  • 00:56:39
    always like you're synchronizing
  • 00:56:41
    something's wrong or you know there's a
  • 00:56:43
    conditional missing and you just got to
  • 00:56:46
    just got to take a step back think about
  • 00:56:49
    what am I doing here where is this data
  • 00:56:51
    going who has control of this data it's
  • 00:56:54
    probably you're just synchronizing it a
  • 00:56:55
    little in correctly but yeah uh hello
  • 00:56:57
    what's better system for what's a better
  • 00:56:59
    system for racing games I don't think
  • 00:57:01
    there is a better system I I if you're
  • 00:57:03
    referring to lag compensation with
  • 00:57:06
    netfox um I I I I I'm guessing that netf
  • 00:57:12
    fox will be able to handle that cuz
  • 00:57:15
    racing is just sinking position
  • 00:57:18
    so lag compensation is perfect for that
  • 00:57:23
    uh I think that netf fox may have some
  • 00:57:25
    impr improvements that will help but I I
  • 00:57:29
    think I think that um client side
  • 00:57:33
    prediction and server reconciliation
  • 00:57:34
    should work fine so the algorithm client
  • 00:57:37
    side prediction and server
  • 00:57:38
    reconciliation is just kind of a a term
  • 00:57:41
    we use for that algorithm where you
  • 00:57:45
    immediately apply your players
  • 00:57:47
    movements and at the same time you send
  • 00:57:50
    those movements those inputs not
  • 00:57:53
    movements but the inputs back to the
  • 00:57:54
    server so you show the player move
  • 00:57:56
    whether it's a car or a character and
  • 00:57:59
    your server makes sure that it's correct
  • 00:58:01
    and then it sends that data back to your
  • 00:58:03
    client and your client's
  • 00:58:06
    like or your server basically telling
  • 00:58:08
    your client hey this is what actually
  • 00:58:10
    happened and if that's what actually
  • 00:58:12
    happened then you don't need to correct
  • 00:58:14
    anything um if there was a correction
  • 00:58:17
    and like the player was like over here
  • 00:58:19
    like the two previous movement nodes
  • 00:58:21
    were like this like it was like one two
  • 00:58:24
    three right and these movement M were
  • 00:58:26
    actually over here well then you would
  • 00:58:27
    just reconcile that player to rerun
  • 00:58:31
    those results in like a frame and then
  • 00:58:33
    you would see the player kind of snap or
  • 00:58:35
    lurp or however you want to smooth it
  • 00:58:37
    out over to where they should be so
  • 00:58:38
    that's kind of like what re that's what
  • 00:58:40
    that does so when we say client side
  • 00:58:42
    prediction we're basically just taking
  • 00:58:44
    inputs so key mouse and keyboard inputs
  • 00:58:47
    running them through hopefully a
  • 00:58:49
    deterministic movement code meaning it
  • 00:58:51
    the same code on their server and client
  • 00:58:53
    should give the same movement output so
  • 00:58:55
    really you should never see a problem
  • 00:58:58
    unless you have a lag Spike and you lose
  • 00:59:00
    data uh and maybe some data never
  • 00:59:03
    reaches your server that's okay we can
  • 00:59:05
    still reconcile those things maybe
  • 00:59:07
    you're actually a little bit over to the
  • 00:59:09
    left further than you thought you
  • 00:59:11
    were whatever that's just you know the
  • 00:59:13
    nature of multiplayer games uh and our
  • 00:59:16
    internet our current internet technology
  • 00:59:18
    so I think this algorithm should work
  • 00:59:21
    fine I think netfox should be a good
  • 00:59:23
    start if you are um concerned about it
  • 00:59:27
    not working the only gotcha that I can
  • 00:59:31
    see the only Improvement off the top of
  • 00:59:32
    my head right now is as part of that
  • 00:59:36
    algorithm this this client side
  • 00:59:39
    prediction there are different aspects
  • 00:59:42
    to it that can
  • 00:59:44
    be exercised or implemented and it's not
  • 00:59:47
    like there's one way to do this right
  • 00:59:49
    there's several ways to do this there's
  • 00:59:51
    several like improvements on how you can
  • 00:59:53
    do this implementation of that and one
  • 00:59:56
    Improvement and if you there's several
  • 00:59:58
    videos on the internet about this with
  • 01:00:01
    like unity and even gdau I think the
  • 01:00:03
    Game Dev uh Channel I can't remember the
  • 01:00:05
    name of it but it's like one of the big
  • 01:00:07
    early gdau multiplayer channels he's got
  • 01:00:09
    a ton of videos out there Game Dev
  • 01:00:11
    Central game development Central I think
  • 01:00:13
    that's the name of the channel go watch
  • 01:00:15
    their series there's like 20 videos
  • 01:00:17
    they're not very long just go watch all
  • 01:00:19
    of them if you're really interested
  • 01:00:20
    because it's very helpful I think
  • 01:00:22
    everybody's watched them
  • 01:00:24
    um and uh I think I've even linked to
  • 01:00:27
    them at the in the description of this
  • 01:00:29
    video
  • 01:00:31
    but one of the things that he does that
  • 01:00:34
    netf fox doesn't is there's a uh this
  • 01:00:39
    capability where your player is rendered
  • 01:00:43
    in current time but everybody else has
  • 01:00:46
    rendered 100 milliseconds in the past
  • 01:00:49
    and they claim in that channel that
  • 01:00:52
    that's industry standard I've read in
  • 01:00:54
    multiple places that that's actually
  • 01:00:56
    true so your competitive first-person
  • 01:00:58
    games will render all the players 100
  • 01:01:01
    milliseconds behind and the idea is that
  • 01:01:03
    you don't really notice that as a human
  • 01:01:05
    like you're not going to really see that
  • 01:01:07
    currently net Fox I don't
  • 01:01:11
    believe renders all the other people 100
  • 01:01:14
    milliseconds they render them as fast as
  • 01:01:17
    possible um and I think what that 100
  • 01:01:20
    millisecond render in the past will do
  • 01:01:22
    is it gives you a buffer of 100
  • 01:01:24
    milliseconds no no matter what the lag
  • 01:01:27
    is you always have a 100 millisecond lag
  • 01:01:31
    that's baked in that won't be noticeable
  • 01:01:33
    so any So This Server reconciliation
  • 01:01:36
    part should be much smoother because
  • 01:01:39
    you're going to have less error
  • 01:01:40
    correction because you give yourself
  • 01:01:42
    that 100 millisecond buffer no matter
  • 01:01:45
    what for all the other players in your
  • 01:01:46
    game right so if you have a 10 V10 match
  • 01:01:49
    you are going to see yourself in current
  • 01:01:51
    time but everybody else is going to be
  • 01:01:53
    100 milliseconds behind and that's not
  • 01:01:55
    really enough time for you to miss those
  • 01:01:57
    like head shot calculations uh so and
  • 01:02:00
    again those are all going to be
  • 01:02:02
    calculated should be calculated on your
  • 01:02:03
    server and then corrected and reconciled
  • 01:02:06
    if if it was actually happening on the
  • 01:02:08
    client now there are some serious
  • 01:02:10
    improvements and optimizations to this
  • 01:02:13
    algorithm I believe valve or not valve
  • 01:02:15
    was it valve yeah whoever call
  • 01:02:17
    Counterstrike people uh I think it was
  • 01:02:19
    Val um I believe they have a even I I
  • 01:02:24
    don't know if it was Counter-Strike
  • 01:02:25
    there is some game out there that I just
  • 01:02:26
    saw an article on I have it linked
  • 01:02:28
    somewhere I might go dig it up but they
  • 01:02:31
    made additional improvements to this to
  • 01:02:34
    those twitch you know firstperson games
  • 01:02:37
    uh recently that are supposed to be
  • 01:02:40
    really even more accurate and it's it's
  • 01:02:43
    about when you take time stamps and how
  • 01:02:46
    accurate that time stamp is and how
  • 01:02:49
    accurate your lag compensation is
  • 01:02:51
    because it's not an exact science it it
  • 01:02:55
    is a
  • 01:02:56
    best case scenario you're making an
  • 01:02:58
    algorithm to handle the generic you know
  • 01:03:01
    the general Public's network connections
  • 01:03:03
    and how you reconcile those those lags
  • 01:03:06
    uh between uh or or the um the delay and
  • 01:03:09
    latency uh between all those connections
  • 01:03:12
    so anyways that's a mouthful for such a
  • 01:03:14
    simple question but I think this should
  • 01:03:16
    be fine I'm going to try to post some
  • 01:03:18
    more links to this later and let's get
  • 01:03:21
    going through
  • 01:03:23
    this um
  • 01:03:27
    chat GPT if I get uh is to check the
  • 01:03:31
    peers Authority and compare it with the
  • 01:03:33
    current peers network ID this makes it
  • 01:03:36
    possible for example to perform beh only
  • 01:03:38
    uh on or from the peer initiating action
  • 01:03:41
    what's the difference between RBC call
  • 01:03:42
    local because this is case we're making
  • 01:03:44
    sure that annotated method is called
  • 01:03:46
    we're also making sure that the
  • 01:03:48
    annotated method is called only on the
  • 01:03:50
    client that initiated the RPC call
  • 01:03:53
    asking chat GPT I've never asked chat
  • 01:03:55
    GPT I I can't imagine chat GPT is just a
  • 01:04:01
    language they don't the AI doesn't know
  • 01:04:04
    these answers it's just a language
  • 01:04:07
    whatever that is called processor that
  • 01:04:09
    just puts the next word in front uh if
  • 01:04:13
    get multiplayer Authority is equal to
  • 01:04:15
    yeah that's how you
  • 01:04:17
    get is this
  • 01:04:19
    client is
  • 01:04:21
    this instance of my player what if it's
  • 01:04:24
    on my machine or the server someone's
  • 01:04:26
    else machine you're
  • 01:04:28
    checking is the authority equal to that
  • 01:04:30
    Pier so this is good for if you're
  • 01:04:33
    checking to see is it client side
  • 01:04:35
    Authority or you know which this is a
  • 01:04:38
    good check to make sure that we don't do
  • 01:04:41
    things on the wrong Pier like this is
  • 01:04:45
    where if you want to make sure that
  • 01:04:47
    inputs are
  • 01:04:48
    only produced from my authority my
  • 01:04:52
    client Authority this is like a good
  • 01:04:53
    check for that um and that that's what
  • 01:04:56
    they're saying that's what they're
  • 01:04:57
    saying uh but for example uh to perform
  • 01:05:00
    only from the period initiate the action
  • 01:05:02
    right so what's difference between that
  • 01:05:05
    and call local call
  • 01:05:08
    local
  • 01:05:10
    is an an annotation uh or a parameter to
  • 01:05:14
    this annotation that means that you can
  • 01:05:18
    also call to the
  • 01:05:21
    local Pier that's that's initiating the
  • 01:05:24
    RPC call so if if you're on a
  • 01:05:27
    client and you make an RPC call by
  • 01:05:29
    default it should call to all other
  • 01:05:33
    clients by
  • 01:05:34
    default and if you add call except for
  • 01:05:38
    the one you're on right so your RPC is
  • 01:05:40
    just like send a message everybody
  • 01:05:42
    except myself like the default RPC
  • 01:05:44
    implementation um now if you add call
  • 01:05:47
    local it says call everybody else and
  • 01:05:50
    myself
  • 01:05:53
    so I'm not really sure
  • 01:05:56
    I mean other than we're making sure the
  • 01:05:58
    ant is call for only on the client that
  • 01:06:00
    initiated it I'm not exactly sure what
  • 01:06:04
    the use case is um these are really good
  • 01:06:07
    questions and I think this is just part
  • 01:06:09
    of multiplayer development is you know
  • 01:06:11
    you've it's really confusing and you the
  • 01:06:15
    tools that you use tend to differ
  • 01:06:17
    slightly they're very similar between
  • 01:06:19
    engines but um they do differ slightly
  • 01:06:22
    where like they don't translate exact
  • 01:06:24
    and like Unity has like much more
  • 01:06:26
    powerful uh tools for certain parts
  • 01:06:29
    about multiplayer and that gdau doesn't
  • 01:06:31
    have yet and uh but we'll get there and
  • 01:06:34
    uh yeah there's a whole there
  • 01:06:36
    aren't many Service uh many videos or
  • 01:06:40
    resources out there in multiplayer which
  • 01:06:41
    is why you know I'm I'm doing this netf
  • 01:06:44
    fox have oh we got a netfox question
  • 01:06:46
    about C well I have netf Fox
  • 01:06:49
    open uh GD script GD script so I don't
  • 01:06:54
    think they support C
  • 01:06:56
    yeah it's just a GD script extension I
  • 01:06:59
    don't think they have support for that
  • 01:07:01
    yet hey netfox you got to list your
  • 01:07:04
    Discord on here they've got a Discord
  • 01:07:06
    now um so here's
  • 01:07:10
    netfox uh Discord and uh Discord let's
  • 01:07:14
    do that I don't think they'll mind I'd
  • 01:07:18
    be curious how character date and items
  • 01:07:19
    inventory play I'm work go oh yeah yeah
  • 01:07:22
    so um I'm definitely planning on I'm
  • 01:07:25
    doing more I I'm yeah saving things to
  • 01:07:29
    the database player logins there are so
  • 01:07:32
    many different services to approach this
  • 01:07:34
    like where do I start well I'm probably
  • 01:07:36
    going to start with steam because
  • 01:07:38
    everybody lists their game on Steam
  • 01:07:40
    steam authentication should be pretty
  • 01:07:43
    straightforward I got a heart face so um
  • 01:07:48
    let's just leave a heart back and you
  • 01:07:50
    know I there's so many ways to do
  • 01:07:52
    databases I mean that's what you mean by
  • 01:07:54
    inventories you know synchronizing we're
  • 01:07:55
    going to get to that I do play to make
  • 01:07:57
    MPL game and I have a question if
  • 01:07:58
    someone's data M the code would they
  • 01:07:59
    find out secrets that that only the
  • 01:08:02
    server
  • 01:08:03
    executes for example when the secret
  • 01:08:05
    boss trigger is possible um yeah if you
  • 01:08:09
    if you deploy if you build your if your
  • 01:08:14
    server code is with your client code
  • 01:08:17
    which right now I've been doing just for
  • 01:08:20
    all my demos just because I think that's
  • 01:08:23
    a little bit more advanced um
  • 01:08:26
    and I just haven't had the time to do a
  • 01:08:28
    separate video on that but if you are
  • 01:08:31
    serious yeah you can structure your game
  • 01:08:34
    in a way that's slightly different where
  • 01:08:36
    you have your server code especially if
  • 01:08:39
    you're if you're using highle
  • 01:08:42
    apis it may be a little harder to get
  • 01:08:46
    away with this like the the built-in
  • 01:08:48
    gdau highle multiplayer apis and maybe
  • 01:08:51
    not but the idea is that you would have
  • 01:08:53
    your server code
  • 01:08:56
    separate from your client code meaning
  • 01:08:58
    you're not going to have shared server
  • 01:09:02
    code in the same file
  • 01:09:05
    so the better way to do it okay so
  • 01:09:08
    there's a couple different ways you can
  • 01:09:09
    have separate projects you can have a
  • 01:09:10
    client in a server but if you're using
  • 01:09:12
    highle apis that's going to be difficult
  • 01:09:14
    because you're what you're going to have
  • 01:09:15
    to do is make sure is that you manage
  • 01:09:18
    the paths that your project is
  • 01:09:21
    structured because your rpcs and your
  • 01:09:23
    synchronizations are going to look for
  • 01:09:25
    that node path and those must be
  • 01:09:26
    identical so if you have uh a player
  • 01:09:30
    object or some World object and in there
  • 01:09:33
    there's a synchronizer or an RPC
  • 01:09:35
    wherever that node and script that that
  • 01:09:38
    rpz exists on has to be identical path
  • 01:09:43
    on both client server or else it won't
  • 01:09:45
    work like player slash input slash
  • 01:09:49
    player synchronizer that same path must
  • 01:09:52
    be the same if you're going to if you're
  • 01:09:54
    going to have an RPC there even if you
  • 01:09:56
    don't use that RPC on your client I'm
  • 01:09:58
    pretty sure that if you read the gdau
  • 01:10:00
    documentation which I was looking at
  • 01:10:01
    yesterday or the day before uh that was
  • 01:10:03
    one of their big warnings that they had
  • 01:10:06
    maybe that will change in the future the
  • 01:10:08
    next thing to consider so that was like
  • 01:10:09
    separate projects the next thing to
  • 01:10:11
    consider is um you can do separate
  • 01:10:16
    projects but don't use the high level
  • 01:10:17
    multiplayer apis meaning you're using
  • 01:10:19
    the lower level maybe you have a UDP
  • 01:10:21
    connection maybe TCP um and you're just
  • 01:10:25
    going to be connecting to some server
  • 01:10:28
    then you're not using highle apis at
  • 01:10:30
    that point you're just sending data then
  • 01:10:33
    then you can manage it however you want
  • 01:10:35
    you don't have to worry about paths
  • 01:10:37
    being the same because you're just
  • 01:10:38
    sending data to some end point or some
  • 01:10:42
    through some socket through some
  • 01:10:43
    connection and then that you know server
  • 01:10:46
    or client whatever respectively just
  • 01:10:48
    knows how to process that data because
  • 01:10:49
    you have to build all that um that's
  • 01:10:52
    message sending and that's a whole other
  • 01:10:54
    thing I haven't gotten to that yet
  • 01:10:55
    eventually I plan on doing that and then
  • 01:10:57
    you can separate out your client server
  • 01:10:59
    and that's probably a lot easier you can
  • 01:11:01
    also have another option is to have a
  • 01:11:03
    shared project with your network code
  • 01:11:06
    that both projects use that way you
  • 01:11:08
    don't have to worry about the paths
  • 01:11:09
    lining up because you built a separate
  • 01:11:12
    like module or extension or something
  • 01:11:14
    for your game that both games inherit
  • 01:11:16
    from now there's complexities and those
  • 01:11:18
    things that I've named because now
  • 01:11:20
    you're managing separate projects you're
  • 01:11:22
    you got to make sure things are imported
  • 01:11:23
    correctly and you have to make sure that
  • 01:11:24
    if you a shared project that you
  • 01:11:27
    maintain the same version between the
  • 01:11:28
    client server because if you don't then
  • 01:11:30
    they're going to mismatch maybe you have
  • 01:11:31
    some logic in one that you didn't share
  • 01:11:33
    in the other okay so that's separate
  • 01:11:35
    projects another way to do it is to
  • 01:11:36
    handle it in different folders where you
  • 01:11:38
    have like a client folder or a client
  • 01:11:40
    folder section and you have a server
  • 01:11:42
    folder section and then when you do your
  • 01:11:43
    dedicated server build or you build your
  • 01:11:45
    clients uh for hosting on Steam for
  • 01:11:49
    example you just exclude the server
  • 01:11:52
    folders for your client builds and
  • 01:11:54
    that's what I would recommend recommend
  • 01:11:55
    doing or you can exclude specific files
  • 01:11:59
    um I don't think
  • 01:12:03
    that when I was talking about how RPC
  • 01:12:06
    paths have to uh be in the same path I
  • 01:12:08
    don't think you need to have the server
  • 01:12:11
    version of that like if you had um
  • 01:12:15
    trying to think what I'm trying to say
  • 01:12:16
    so if you call an RPC from a server file
  • 01:12:19
    that should only really be called from
  • 01:12:21
    the server I don't know if that same
  • 01:12:23
    file has to exist on your client as as
  • 01:12:25
    well um I I'm I'm guessing no the way
  • 01:12:30
    I'm thinking about it like so if you had
  • 01:12:31
    like all your server rpcs in one file um
  • 01:12:34
    for like your player I don't think that
  • 01:12:37
    you necessarily have to have those on
  • 01:12:39
    the client but if you do just don't put
  • 01:12:41
    any logic in those like let's say you do
  • 01:12:45
    have to have those rpcs um on both
  • 01:12:48
    client server you could have like a a
  • 01:12:50
    shared file that will have your RPC
  • 01:12:53
    stubbed out but just don't put your
  • 01:12:55
    server logic in there like for example
  • 01:12:58
    if a
  • 01:13:01
    player if you have a secret and you have
  • 01:13:06
    a client side um well technically what I
  • 01:13:09
    would do is I would so for this
  • 01:13:13
    example I think you would have like some
  • 01:13:16
    object that maybe only exists on your
  • 01:13:18
    server like maybe you can find a way to
  • 01:13:20
    not you know put like if you when you
  • 01:13:22
    ship your client don't put that object
  • 01:13:25
    there and that object would have a ont
  • 01:13:28
    trigger effect through you know on
  • 01:13:31
    bodybody collision or on body Ender or
  • 01:13:33
    something like that and your server I
  • 01:13:35
    mean you can have it on the client
  • 01:13:37
    that's fine whatever you just ignore it
  • 01:13:38
    but on the server side when that trigger
  • 01:13:41
    happens call to some function and then
  • 01:13:44
    have that function uh make an RPC call
  • 01:13:48
    to that or or do some action and that is
  • 01:13:52
    only on the server and because you you
  • 01:13:55
    excluded those files from your client
  • 01:13:56
    build um I'm going to I'm rambling a lot
  • 01:13:59
    about this but I think the best way to
  • 01:14:01
    do this is to experiment try something
  • 01:14:03
    really easy where you create a build for
  • 01:14:07
    your client and exclude your server uh
  • 01:14:10
    the server files or scripts that are
  • 01:14:13
    going to actually do the secrets and so
  • 01:14:16
    if they do data mind your client all
  • 01:14:19
    they're going to see is maybe a
  • 01:14:22
    collision that makes an RPC call to the
  • 01:14:24
    back end and or I wouldn't even do it
  • 01:14:27
    that way if you're trying to be super
  • 01:14:28
    secretive you could still have the
  • 01:14:30
    Collision but it just doesn't do
  • 01:14:31
    anything on the client maybe just
  • 01:14:32
    ignores it and then you you can manually
  • 01:14:35
    you can do a detect yeah I'm kind of
  • 01:14:37
    thinking out loud here um if you're if
  • 01:14:41
    you're I guess maybe I don't know how
  • 01:14:44
    you would not be able to not put that on
  • 01:14:46
    the client but you could have a check
  • 01:14:49
    that's
  • 01:14:51
    like if
  • 01:14:53
    server uh
  • 01:14:55
    only uh only add this uh signal only
  • 01:14:58
    connect the signal the on enter body
  • 01:15:00
    signal if it's on a server so like if
  • 01:15:03
    Authority you know only add this signal
  • 01:15:06
    so maybe that you wherever that signal
  • 01:15:10
    lives is in another script and nobody
  • 01:15:13
    knows what that signal does and you just
  • 01:15:15
    exclude that script from the server uh
  • 01:15:17
    from the client build and you only use
  • 01:15:19
    that uh script on the server so that
  • 01:15:22
    could totally so you can you still might
  • 01:15:24
    have to have like some of the initial
  • 01:15:26
    setup that could be exposed so people
  • 01:15:27
    maybe people would see that you know I
  • 01:15:30
    don't know you're going to have to work
  • 01:15:31
    through this and really figure that out
  • 01:15:32
    I like this problem and I think I would
  • 01:15:35
    like to do a video on this eventually um
  • 01:15:39
    so I'm gonna actually just write a note
  • 01:15:41
    so I don't forget to do it and the last
  • 01:15:44
    one I'm going to look at
  • 01:15:46
    today got stuck on the jump stuff yeah
  • 01:15:50
    so what's happening is jump jump can be
  • 01:15:54
    handled different ways like in various
  • 01:15:57
    approaches over the last year and maybe
  • 01:16:01
    I've used an RPC for some of my jumps
  • 01:16:03
    maybe I use a sync variable for some of
  • 01:16:05
    my jumps uh the input type has changed
  • 01:16:08
    from you know on pressed to get strength
  • 01:16:12
    get input strength uh it really depends
  • 01:16:14
    on what you're trying to do with jump
  • 01:16:16
    and I think in in this tutorial I the 3D
  • 01:16:21
    tutorial the jump mechanisms there I I
  • 01:16:23
    like a little bit better um and and I'm
  • 01:16:26
    actually doing State machine jump right
  • 01:16:29
    now with this and one of the things I'm
  • 01:16:31
    addressing in this stream and not part
  • 01:16:34
    four but I guess part five which will
  • 01:16:35
    come out next week is the actual
  • 01:16:37
    implementation of the jump Logic the
  • 01:16:40
    start of the jump logic so I don't have
  • 01:16:42
    it finished but I think what jump will
  • 01:16:44
    be split up into is jump up and then a
  • 01:16:48
    fall state so you know you're going to
  • 01:16:52
    move to the jump up state or jump state
  • 01:16:54
    by hitting space bar but then you have
  • 01:16:56
    to fall down and that should be like a
  • 01:16:59
    different state should be a different
  • 01:17:00
    animation because fall State can happen
  • 01:17:03
    if you just run off a ledge so if you
  • 01:17:04
    detect that you're falling down change
  • 01:17:07
    your player if not on ground oh you're
  • 01:17:10
    in Fall state or if you jump up then
  • 01:17:12
    transition to a fall State until you hit
  • 01:17:14
    the ground and then once you're on
  • 01:17:15
    ground again then you move back to idle
  • 01:17:17
    or moving or run or walk state or
  • 01:17:19
    whatever uh so I think that's kind of
  • 01:17:22
    covers what's going on with this but
  • 01:17:24
    yeah you're going to have to do some
  • 01:17:25
    stuff the the do jump thing that I did
  • 01:17:27
    in in this
  • 01:17:29
    example may not be the best you might
  • 01:17:32
    find some improvements I'm sure there's
  • 01:17:34
    an improvement on it I just need I
  • 01:17:35
    wanted to have something just really
  • 01:17:36
    basic working so yeah there's definitely
  • 01:17:38
    some more work to be done there all
  • 01:17:40
    right well I'm I'm going to wrap up with
  • 01:17:42
    these couple comments here and thanks
  • 01:17:44
    for coming by I'm just going to get
  • 01:17:45
    through these uh questions really quick
  • 01:17:48
    and then I'm going to bail uh and uh
  • 01:17:52
    yeah this was good um appreciate you
  • 01:17:54
    stopping by uh so this person was saying
  • 01:17:57
    uh they had a
  • 01:17:59
    typo uh when they were doing the what
  • 01:18:03
    was I saying did you select the dedicate
  • 01:18:05
    oh here we go today I tested Brack's
  • 01:18:07
    game with pgp over steam with the friend
  • 01:18:09
    Connection work perfectly I got
  • 01:18:10
    thousands of strange warnings yeah yeah
  • 01:18:13
    I opened that um so yeah thanks for that
  • 01:18:17
    guys uh and uh so I'm I'm I'm done with
  • 01:18:21
    Discord for today uh and this person was
  • 01:18:23
    asking about uh
  • 01:18:26
    uh they were saying the zooms were a
  • 01:18:27
    little Annoying and yeah I totally get
  • 01:18:29
    it uh can uh but I got something good
  • 01:18:32
    things I can spawn and hit kill
  • 01:18:33
    multiplayer enemies but anybody join
  • 01:18:34
    later he will see enemy ghosts enemy but
  • 01:18:36
    if anyone joins later he will see enemy
  • 01:18:38
    ghosts
  • 01:18:41
    um yeah I think I think you have to
  • 01:18:44
    despawn from the server um yeah I think
  • 01:18:48
    there's a way to despawn off the top of
  • 01:18:50
    my head I think you just uh I think you
  • 01:18:52
    can Q free on the server and that should
  • 01:18:55
    do it
  • 01:18:59
    um yeah you basically have to remove
  • 01:19:01
    them I think you have to do a despawn by
  • 01:19:03
    running a q free all right so let's see
  • 01:19:08
    what else kind of I think I had some
  • 01:19:13
    more yeah I'm I'm not going to do nakama
  • 01:19:17
    anytime soon I I
  • 01:19:19
    I I really it's really expensive uh and
  • 01:19:23
    it it looks really good and it looks
  • 01:19:25
    really feature like when I say good I
  • 01:19:28
    just mean it the feature sets seem
  • 01:19:30
    pretty strong and I think it's a a
  • 01:19:32
    really comprehensive uh multiplayer
  • 01:19:35
    solution I just don't I think it's going
  • 01:19:37
    to be a while before I get to them um
  • 01:19:40
    there was a multiplayer there's another
  • 01:19:43
    big gdau YouTuber um he just did a
  • 01:19:46
    nakama server I don't know if it's
  • 01:19:49
    public though so I would check I would
  • 01:19:53
    look around for that I don't have his
  • 01:19:56
    channel on the top of my head right now
  • 01:19:58
    but yeah I would I would just check to
  • 01:20:00
    see if um man I wish I could wish I
  • 01:20:04
    could post to that really quick um what
  • 01:20:08
    was his name oh oh fine point
  • 01:20:12
    CGI fine
  • 01:20:15
    point CGI yeah you know I'm not GNA be
  • 01:20:18
    able to get to everything but maybe
  • 01:20:19
    somebody else did um so yeah you guys
  • 01:20:22
    just uh bunch YouTubers out there doing
  • 01:20:25
    some good stuff so all right I think I
  • 01:20:27
    think I got through everything all right
  • 01:20:28
    well that was a good stream uh I'm glad
  • 01:20:31
    I got I got you some help today um I

    and I'm gonna start streaming I'm going
  • 01:20:42
    to try to stream more regularly

    template wrapped up
  • 01:20:49
    and uh move on to the next thing and I'm
  • 01:20:52
    going to try to just stream my
  • 01:20:53
    development process a little a little
  • 01:20:54
    bit more and uh try to get used to that
  • 01:20:57
    setup thank you so much for coming by
