Resumo

TLDRIn this Unreal Engine 5 tutorial, Mizo Frizzo demonstrates how to create a basic stamina system. The system allows players to sprint by holding the left shift key, consuming stamina in the process. Two types of progress bars (horizontal and radial) are utilized to visually represent stamina levels on the UI. Players can run until their stamina reaches zero, at which point they cannot sprint for 2.5 seconds while stamina replenishes. The tutorial details the blueprints required for setting up the character movement, sprint mechanics, consumption of stamina, and the UI elements that display stamina levels. Additionally, it covers how to incorporate radial progress bars into the system for better visual representation.

    Mizo Frizzo from Pitchfork Academy introduces a tutorial on creating a stamina system in Unreal Engine 5. The tutorial features two types of progress bars and covers how stamina is consumed while running and replenished afterwards. Key mechanics include a pause before replenishment, the ability to sprint only when stamina is available, and specific timings for depletion and recovery.

  • 00:05:00 - 00:10:00

    The video continues with character setup in Unreal Engine, where Mizo establishes sprint functionality. Variables for running status and stamina consumption are created, alongside a mechanism for clamping stamina levels. The player’s ability to sprint is tied to stamina levels, ensuring that when stamina is depleted, the sprint function disables, halting movement and initiating the replenishment phase.

    In the final segment, he incorporates a user interface featuring a progress bar to visually display stamina. He adds a radial progress bar and integrates it into the stamina management system. The tutorial concludes with a demonstration of the fully operational stamina system, encouraging viewers to like and follow for more tutorials.

  • 00:00:00
    what's up guys mizo frizzo from
  • 00:00:01
    Pitchfork Academy here and in this
  • 00:00:03
    Unreal Engine 5 tutorial I'm going to
  • 00:00:06
    show you how to set up a basic stamina
  • 00:00:10
    system with a progress bar so as you can
  • 00:00:13
    see here I am walking and if I hold the
  • 00:00:16
    left shift I can run and it will use up
  • 00:00:18
    my stamina and just to demonstrate I've
  • 00:00:22
    got two kinds of progress bars here I've
  • 00:00:24
    got the standard horizontal one and I've
  • 00:00:27
    got the radial one which you can can
  • 00:00:30
    make in another one of my tutorials so
  • 00:00:32
    I'll be showing you how to set that one
  • 00:00:34
    up as well but basically my stamina will
  • 00:00:37
    replenish if I'm not sprinting if I
  • 00:00:39
    Sprint it will use it up and if I stop
  • 00:00:42
    sprinting it will pause for 1 second
  • 00:00:44
    before it starts replenishing and if it
  • 00:00:46
    runs out all the way to zero it will be
  • 00:00:49
    empty for 2.5 seconds before it starts
  • 00:00:52
    replenishing and I will not be able to
  • 00:00:55
    sprint in that time until I get some
  • 00:00:57
    stamina back so without further ado guys
  • 00:01:00
    let me show you how to do this all
  • 00:01:02
    righty guys now all I've done is create
  • 00:01:04
    a new project using the third person
  • 00:01:06
    template and the first thing I'm going
  • 00:01:08
    to do is just set up my character's
  • 00:01:11
    ability to Sprint so I'm going to open
  • 00:01:13
    my BP third person character find some
  • 00:01:15
    empty space and I'm going to right click
  • 00:01:17
    and find left shift and on pressing of
  • 00:01:21
    the left shift the first thing I'm going
  • 00:01:23
    to do is set a Boolean uh to know if I'm
  • 00:01:26
    running I'm going to call it is running
  • 00:01:29
    question mark
  • 00:01:30
    and I am going to set this as true on
  • 00:01:35
    pressed and as false on released like so
  • 00:01:41
    uh the next thing I'm going to do is
  • 00:01:43
    change the walk speed of my character
  • 00:01:45
    inside of the character movement but as
  • 00:01:47
    you can see if you select the character
  • 00:01:49
    movement the default Max walk speed is
  • 00:01:51
    500 and just to accentuate this I'm
  • 00:01:54
    going to change this to
  • 00:01:56
    250 and then I'm going to set it to
  • 00:01:59
    something like 800 so I'm going to find
  • 00:02:02
    set max walk speed I'm going to
  • 00:02:05
    duplicate this I'm going to set it to
  • 00:02:07
    800 on pressed and on released I'm going
  • 00:02:10
    to set it back to
  • 00:02:13
    250 make sure that you connect the
  • 00:02:16
    character movement component to the
  • 00:02:18
    Target
  • 00:02:20
    here nice and that should be working so
  • 00:02:25
    I'll just double check that if I walk
  • 00:02:28
    I've got 250 and if I hold left shift
  • 00:02:31
    I've got that 80000 Max walk speed so I
  • 00:02:33
    can Sprint very nice okay uh now the
  • 00:02:38
    next thing I'm going to add before we
  • 00:02:40
    add in the stamina is just to check uh
  • 00:02:44
    if we can run uh because we will want to
  • 00:02:47
    set this to false to stop our player
  • 00:02:49
    from running when for example the
  • 00:02:52
    stamina reaches zero and it takes a
  • 00:02:54
    couple of seconds to replenish so I'm
  • 00:02:56
    going to add a variable I'm going to
  • 00:02:58
    call it can run question
  • 00:03:01
    mark and I'm going to compile and I'm
  • 00:03:04
    going to set the default value of can
  • 00:03:06
    run to True and then I'm going to get
  • 00:03:08
    can run hold B and click to get a branch
  • 00:03:12
    put this on a branch right here and now
  • 00:03:14
    we will only run if we indeed can run
  • 00:03:18
    the next thing I want to do is start
  • 00:03:20
    setting up our stamina consumption so
  • 00:03:23
    I'm going to right click down here add a
  • 00:03:25
    custom event and call it
  • 00:03:28
    consume stem
  • 00:03:31
    and I'm going to call this custom event
  • 00:03:33
    right here every time we run uh we are
  • 00:03:35
    going to call consume
  • 00:03:39
    stamina and all I'm going to do uh to
  • 00:03:42
    get this started is create a new
  • 00:03:45
    variable and call it stamina it's going
  • 00:03:48
    to be a float and I'm going to compile
  • 00:03:51
    and I'm going to set the default value
  • 00:03:53
    of stamina 2 1 now you may want to set
  • 00:03:58
    this as 100
  • 00:04:00
    but uh progress bars typically use a
  • 00:04:03
    value between 0 and 1 Z being empty and
  • 00:04:06
    one being full so I'm actually just
  • 00:04:09
    going to make uh my full amount of
  • 00:04:12
    stamina equal 1 so I'm basically going
  • 00:04:15
    to divide everything by 100 uh so that I
  • 00:04:18
    don't have to actually do that uh you
  • 00:04:21
    know with nodes I don't have to divide
  • 00:04:23
    everything by 100 to set the progress
  • 00:04:25
    bar so I'm going to set stamina here and
  • 00:04:29
    I'm going to set stamina as the
  • 00:04:33
    stamina
  • 00:04:34
    minus something like
  • 00:04:37
    0.025 so 22% of my stamina every time
  • 00:04:41
    this is called and then I am going to
  • 00:04:44
    check if I am running so I am going to
  • 00:04:49
    grab my is running Boolean hold B and
  • 00:04:52
    click to get a branch and if we are
  • 00:04:55
    running we are essentially going to uh
  • 00:04:58
    continue cons assuming stamina um and I
  • 00:05:03
    will put a print string here actually I
  • 00:05:05
    will just put it before the branch just
  • 00:05:08
    put a print string
  • 00:05:10
    here and plug in my
  • 00:05:13
    stamina and then if we are still running
  • 00:05:17
    what I'm going to do is get a
  • 00:05:19
    retriggerable delay and I'm going to set
  • 00:05:21
    this to
  • 00:05:24
    0.05 and then I am going to call assume
  • 00:05:28
    stamina
  • 00:05:30
    again so when we start running it's
  • 00:05:33
    going to call this event consume stamina
  • 00:05:36
    it's going to consume some stamina and
  • 00:05:39
    then it's going to check if we're still
  • 00:05:40
    running and if we are still running it
  • 00:05:42
    is going to delay and call itself again
  • 00:05:47
    so this will keep running over and over
  • 00:05:49
    again so if we press play now and I hold
  • 00:05:52
    shift to run you'll see uh that it is
  • 00:05:55
    consuming stamina and one of the things
  • 00:05:58
    you'll noticed is that it is going into
  • 00:06:00
    the negative there so we can very easily
  • 00:06:03
    fix that by putting a clamp right here
  • 00:06:07
    clamp float
  • 00:06:09
    whoops clamp float and very conveniently
  • 00:06:13
    the Min and Max is already zero and one
  • 00:06:17
    so we don't need to change anything
  • 00:06:18
    there nice um now we want to start
  • 00:06:24
    adding some other stuff to the
  • 00:06:26
    consumption of this stamina such as as
  • 00:06:30
    uh if the stamina reaches zero uh we
  • 00:06:32
    want to stop our player from sprinting
  • 00:06:36
    so what we can do is uh just disconnect
  • 00:06:41
    this right here and move this out a
  • 00:06:43
    little bit and we are going to check if
  • 00:06:46
    our stamina is
  • 00:06:49
    equal to zero and put another Branch
  • 00:06:56
    here and if the stamina is equal to zero
  • 00:07:00
    the first thing that we want to do is
  • 00:07:03
    set this is running uh so we can just
  • 00:07:07
    grab these nodes right here that is
  • 00:07:09
    running and the set back to the walk
  • 00:07:11
    speed right here so if it equals zero
  • 00:07:14
    it's going to set is running to false
  • 00:07:16
    and it's going to stop us from running
  • 00:07:19
    like so and
  • 00:07:22
    um we will create our stamina
  • 00:07:27
    replenishment in a moment um but what
  • 00:07:30
    we'll do is just grab these two nodes
  • 00:07:32
    here and plug these into the false so if
  • 00:07:34
    our stamina is not equal to zero it will
  • 00:07:38
    delay and continue consuming stamina so
  • 00:07:43
    we can see this at work now if I run and
  • 00:07:47
    I let go before it's zero I should still
  • 00:07:49
    be able to run and when it gets to zero
  • 00:07:52
    it is stopping me from running nice and
  • 00:07:54
    if I try to run now it just says my
  • 00:07:56
    stamina is zero so that's all working
  • 00:07:58
    correctly but we just need the ability
  • 00:08:00
    to replenish our stamina so what we can
  • 00:08:04
    do is we can create another custom event
  • 00:08:06
    and we'll call it
  • 00:08:08
    replenish
  • 00:08:11
    stamina let double check that I spelled
  • 00:08:13
    that correctly and I have not replenish
  • 00:08:16
    stamina and uh what we're going to do
  • 00:08:20
    with this is we're going to call it on a
  • 00:08:24
    timer by event and this will allow us to
  • 00:08:27
    sort of um have a bit more control over
  • 00:08:32
    when this is called and for example when
  • 00:08:35
    we run out of stamina or we stop
  • 00:08:39
    sprinting uh we can add a little pause
  • 00:08:41
    in there so that's kind of why I have
  • 00:08:44
    this is running Branch right here
  • 00:08:47
    because this will keep calling itself
  • 00:08:49
    over and over again but if we release
  • 00:08:52
    the left shift button and we are no
  • 00:08:56
    longer running what we can do is set
  • 00:08:59
    timer by
  • 00:09:01
    event the event is going to be this
  • 00:09:04
    replenish stamina right here and this
  • 00:09:06
    will be the uh amount of time it will
  • 00:09:10
    pause for before replenishing your
  • 00:09:13
    stamina if you stop running so I'm going
  • 00:09:16
    to put this as 1 second and the first
  • 00:09:19
    thing I'm going to do when we call this
  • 00:09:21
    replenish stamina is check if we are
  • 00:09:25
    totally out of stamina so I can grab
  • 00:09:27
    this stamina equals z and Branch right
  • 00:09:30
    here and duplicate it down here and if
  • 00:09:34
    we are indeed out of stamina what we're
  • 00:09:37
    going to do is set can run to
  • 00:09:40
    false and then we are going to put in a
  • 00:09:46
    delay and I'm going to make the
  • 00:09:50
    delay 2.5 seconds decent delay um and
  • 00:09:55
    then what we will do is reduce our
  • 00:09:58
    stamina so so we can get our stamina and
  • 00:10:02
    we can sorry we can replenish our
  • 00:10:04
    stamina increase our stamina not reduce
  • 00:10:07
    so I'm going to make this 0.01 cuz I
  • 00:10:10
    want it to replenish quite slowly and we
  • 00:10:13
    can grab a clamp float duplicate this
  • 00:10:17
    down
  • 00:10:18
    here and set our stamina as the output
  • 00:10:23
    of that clamp so after we've stopped our
  • 00:10:27
    player from sprinting we are delaying by
  • 00:10:29
    2.5 seconds before we start to replenish
  • 00:10:32
    our stamina and then we can give them
  • 00:10:35
    the ability to Sprint back so we can
  • 00:10:39
    change can run to True and then what we
  • 00:10:43
    want is a retriggerable delay
  • 00:10:47
    retriggerable delay and this is going to
  • 00:10:51
    be our very small number
  • 00:10:53
    0.05 and we're going to call replenish
  • 00:10:57
    stamina again
  • 00:11:00
    so if this is called and we are out of
  • 00:11:04
    stamina we're stopping the player from
  • 00:11:06
    sprinting for 2.5 seconds and then we're
  • 00:11:10
    starting to increase the stamina give
  • 00:11:12
    them the ability to run again and
  • 00:11:14
    calling itself again so the second time
  • 00:11:18
    this will call it will not be zero
  • 00:11:21
    anymore because we've added 0.1 to it oh
  • 00:11:24
    sorry this should be 01 uh my mistake
  • 00:11:28
    and uh and so here we can basically grab
  • 00:11:32
    these nodes right here and duplicate
  • 00:11:35
    them so if we do have some stamina we're
  • 00:11:39
    going to continue increasing it and we
  • 00:11:42
    can grab this retriggerable delay right
  • 00:11:47
    here and then we want to check um if
  • 00:11:50
    it's full and if we're running basically
  • 00:11:53
    so what we can do is drag off of this
  • 00:11:55
    pin right here and get a less node and
  • 00:11:59
    and check that it is less than one so
  • 00:12:02
    less than full if it's full we don't
  • 00:12:04
    want to continue replenishing it and I'm
  • 00:12:08
    going to also get an and Boolean here
  • 00:12:12
    and I'm going to also get a not
  • 00:12:16
    Boolean and check that we are not
  • 00:12:19
    running so plug is running into here
  • 00:12:24
    so if the stamina is not full and we're
  • 00:12:27
    not running then we will will continue
  • 00:12:30
    to replenish our stamina so put a branch
  • 00:12:33
    on this and we already have our delay
  • 00:12:37
    here and we can get our call to our
  • 00:12:41
    replenish stamina like
  • 00:12:44
    so nice and if I get this print string
  • 00:12:48
    and I put it down here uh in front
  • 00:12:54
    of wherever we set the stamina
  • 00:13:00
    like
  • 00:13:01
    so just before we set up our progress
  • 00:13:03
    bar we can see this at
  • 00:13:06
    work and this should all be working
  • 00:13:09
    correctly now so if I compile and hit
  • 00:13:11
    play and I start running see we've got
  • 00:13:14
    our
  • 00:13:15
    stamina it is pausing for 1 second if I
  • 00:13:20
    stop running and filling back up
  • 00:13:23
    again and if I use it all the way to
  • 00:13:26
    zero I am unable to Sprint until it
  • 00:13:30
    starts increasing
  • 00:13:32
    again which it is not it is not
  • 00:13:36
    increasing again so something is up here
  • 00:13:38
    ah I uh I didn't plug this execution pin
  • 00:13:42
    back in when I put the print string in
  • 00:13:44
    there I forgot to put a call to the uh
  • 00:13:47
    replenish stamina on the end of my
  • 00:13:50
    consume stamina here so when we run out
  • 00:13:52
    of stamina completely um I've just
  • 00:13:55
    forgot to put in a call to our replenish
  • 00:13:59
    stamina that's all that was there sorry
  • 00:14:02
    about that guys so now when it gets to
  • 00:14:05
    zero it should pause for 2.5 seconds and
  • 00:14:08
    then start increasing again and then I
  • 00:14:10
    can indeed run again and if I try to run
  • 00:14:14
    well it's at zero it won't let me until
  • 00:14:17
    it replenishes and I actually have some
  • 00:14:20
    stamina to run nice so uh this uh looks
  • 00:14:25
    a bit crappy with the print string so
  • 00:14:28
    let's set up a progress bar very very
  • 00:14:30
    quickly so I'm going to delete these
  • 00:14:33
    print strings
  • 00:14:35
    here and I'm going to create a widget
  • 00:14:38
    very very quickly to display this
  • 00:14:41
    stamina on screen so let's just in our
  • 00:14:46
    third person blueprints folder right
  • 00:14:47
    click and go to user interface widget
  • 00:14:49
    blueprint user widget and I'm going to
  • 00:14:51
    call this wbp
  • 00:14:53
    uncore stamina and open this up I am
  • 00:14:58
    going to add a a canvas
  • 00:15:01
    panel and I'm also going to add a
  • 00:15:04
    progress bar to that canvas panel I'm
  • 00:15:07
    going to leave it anchored to the top
  • 00:15:08
    left here but because I'm a Dark Souls
  • 00:15:11
    fan I'm going to make this long and
  • 00:15:13
    skinny like so I'm going to change the
  • 00:15:17
    color to
  • 00:15:20
    green and I'm going to change the
  • 00:15:23
    default percentage to one so it is full
  • 00:15:27
    by default and then I can click bind
  • 00:15:29
    create binding and in here I am going to
  • 00:15:33
    cast to my third person
  • 00:15:37
    character and get player
  • 00:15:42
    porn and
  • 00:15:44
    then get my stamina from my
  • 00:15:50
    porn and I just need to add this widget
  • 00:15:53
    to the viewport so in my third person
  • 00:15:56
    character I'm just going to
  • 00:16:00
    do this on event begin play right here I
  • 00:16:02
    am going to create
  • 00:16:05
    Widget the widget I'm going to create is
  • 00:16:07
    wbp stamina and then I will add to
  • 00:16:16
    viewport and that's it that should all
  • 00:16:18
    be working so I'm going to compile and
  • 00:16:20
    save and hit play we see we've got this
  • 00:16:23
    stamina bar up the top left um I'm
  • 00:16:26
    losing a bit of FPS here
  • 00:16:29
    it's tanking um it'll probably just take
  • 00:16:31
    a moment to catch
  • 00:16:33
    up there we go but you can see my
  • 00:16:36
    stamina is filling when I stop
  • 00:16:38
    sprinting I can Sprint if I stop it's
  • 00:16:41
    going to pause for 1 second before it
  • 00:16:43
    starts to fill up and if it runs out to
  • 00:16:45
    zero it will pause for 2.5 seconds and
  • 00:16:49
    it will stop me from sprinting and then
  • 00:16:52
    refill
  • 00:16:54
    again nice just as a bonus guys I'm
  • 00:16:57
    going to set up my radial progress bar
  • 00:17:00
    and uh show you how to make this work
  • 00:17:03
    with my radial progress bar so that's it
  • 00:17:05
    for the stamina system and a basic
  • 00:17:08
    horizontal progress bar as you can see
  • 00:17:10
    here but uh if you'd like to follow
  • 00:17:13
    along with the next part you can check
  • 00:17:14
    out my how to create a radial progress
  • 00:17:17
    bar in Unreal Engine 5 tutorial um and
  • 00:17:21
    I'm going to set this up to work with
  • 00:17:23
    that progress bar now all righty guys so
  • 00:17:26
    I've added my radial progress bar to
  • 00:17:28
    this project
  • 00:17:29
    I have just deleted that other progress
  • 00:17:31
    bar from the widget and added my radial
  • 00:17:33
    progress bar and um you know this is set
  • 00:17:37
    up with everything from the tutorial
  • 00:17:39
    where we create it so in the graph it
  • 00:17:43
    has an uh update percentage function
  • 00:17:46
    just like we did in the other tutorial
  • 00:17:48
    so I've got this function where we
  • 00:17:49
    update the percentage of the radial
  • 00:17:51
    progress bar and to make this work all
  • 00:17:54
    I'm going to have to do is create a
  • 00:17:58
    reference to this widget that contains
  • 00:18:00
    the radial progress bar so I'm going to
  • 00:18:03
    promote this to a variable I'm going to
  • 00:18:05
    call it UI
  • 00:18:08
    Main and just connect this in here like
  • 00:18:13
    so and now that we have this UI main
  • 00:18:16
    anytime that we update the percentage
  • 00:18:19
    here we set the percentage we can just
  • 00:18:21
    get the UI main get the radial progress
  • 00:18:25
    bar inside of it and then call that
  • 00:18:29
    update percentage
  • 00:18:30
    function and pass
  • 00:18:33
    through the stamina like so and the
  • 00:18:36
    stamina just has to be a value of
  • 00:18:38
    between Zer and 1 so if for example you
  • 00:18:40
    set the stamina to 100 you would have to
  • 00:18:44
    uh divide it by 100 to get the correct
  • 00:18:46
    percentage for the progress bar I can
  • 00:18:48
    grab these three nodes here and I can
  • 00:18:51
    duplicate them and put them in front of
  • 00:18:54
    anywhere where we calculate the stamina
  • 00:18:58
    plug in the execution pins and plug the
  • 00:19:01
    stamina into the percentage like
  • 00:19:05
    so and that is literally all we have to
  • 00:19:08
    do to make this stamina system work with
  • 00:19:10
    my radial progress bar so if I hit play
  • 00:19:13
    you'll see we've got our radial progress
  • 00:19:15
    bar and once again my FPS is tanking I
  • 00:19:19
    don't really know why um I think it's
  • 00:19:21
    because I've got um multiple Unreal
  • 00:19:24
    Engine editors open right now uh there
  • 00:19:27
    we go it's caught up so you can see that
  • 00:19:30
    that is draining just like our other
  • 00:19:32
    progress bar if it runs out we are
  • 00:19:34
    unable to Sprint for 2.5 seconds nice
  • 00:19:38
    and then it is
  • 00:19:40
    replenishing and if we stop sprinting
  • 00:19:42
    it'll pause for 1 second and start to
  • 00:19:45
    replenish again nice that's it guys if
  • 00:19:49
