How do i build a stamina bar?

Asked 5,734 views1 answers

I'm trying to build a stamina bar GUI for my game. I already built a Health Gui from AlvinBlox's youtube channel. Don't worry i tried to understand about the guis. I started thinking how to start scripting. I tried setting an IntValue to stamina. Such as 100. And then i told the script: if the player's walkspeed is above 16 then substract 1 from the so-called 'STAMINA POINTS' each second. Here's what my code sort of looked like. Am I going the right way? I used a local script. What else could I use?


local player = game.Players.LocalPlayer 
local humanoid = player.Character.Humanoid --------------------- HUMANOID?
local staminabar = script.Parent -------------------------THE ACTUAL STAMINA BAR
local staminaframe = script.Parent.Parent ---------------------FRAME THAT HOLD THE BAR
local staminamax = 100 ----------------------------MAXIMUM STAMINA

humanoid.Changed:connect(function()

local stamina = Instance.new('IntValue', player)
stamina.Name = 'StaminaVal'
stamina.Value = 100

	while true do
		if humanoid.WalkSpeed > 16 then ------------if walkspeed > 16 then waste stamina
			stamina.Value = stamina.Value - 1
			wait(1)
		end
	end

	script.Parent.Size = UDim2.new(stamina.Value/staminamax,0,1,0)

end)

Well, it'll only work if the player's WalkSpeed value is greater than 16, and not when running/ walking/ etc.; if that's your intention, then I recommend using the Magnitude value of Velocity from the player's torso, which is a bit complicated & may be overdoing things. :P

I forgot to mention this, but i really only want to waste stamina when WalkSpeed is faster than 16. So long as its above 16 stamina decreases. Which is really boring. If you have any other suggestions on how i should use the stamina bar please let me know.

You're almost there. Just need to make a couple of changes:

  • 1) Create the Stamina value on the server. Reference it on the client. This can be done using a PlayerAdded event with a Script in ServerScriptStorage.

  • 2) Add the walkspeed condition to your while loop, so it doesn't run forever.

  • 3) Add a debounce to prevent multiple firings of the event subtracting your value.

local player = game.Players.LocalPlayer

repeat wait() until player.Character --Wait for the character

local humanoid = player.Character.Humanoid
local staminaframe = script.Parent.Parent
local staminabar = script.Parent
local staminamax = 100
local db = false --Step 3

local stamina = player:WaitForChild("StaminaVal") --Step 1

humanoid.Changed:connect(function()
	if not db then
		db = true
		while humanoid.WalkSpeed > 16 and wait(1) do --Step 2
			stamina.Value = stamina.Value - 1
			staminabar.Size = UDim2.new(stamina.Value/staminamax,0,1,0)
		end
		db = false
	end
end)
