LocalScript doesnt change walkspeed of character

What do you want to achieve?

I’m trying to make a sprint system + stamina system

What is the issue?

If I stop holding LeftShift and the player still has stamina, it will force the player to sprint until the stamina reaches 0.

Local script:

local cs = game:GetService('ContextActionService')
local ts = game:GetService('TweenService')
local players = game:GetService('Players')
local localplayer = players.LocalPlayer
local character = localplayer.Character
local humanoid = character:WaitForChild('Humanoid')

local bar = script.Parent:FindFirstChild('bar')
local config = script.Parent:FindFirstChild('staminaConfig')

local tweenInfo = TweenInfo.new(
	config.tweenTime.Value,
	Enum.EasingStyle.Quint,
	Enum.EasingDirection.Out,
	0,
	false
)

local loopPlaying = false
local function staminaHandler(continuee:boolean)
	local cour = coroutine.create(function()
		while task.wait(config.time.Value) do
			if config.staminaCapacity.Value > 0 then
				print('Loop is playing')
				loopPlaying = true
				config.staminaCapacity.Value -= config.removePerSecond.Value
			else
				loopPlaying = false
				print('Loop stopped')
				break
			end
		end
	end)

	local regen = coroutine.create(function()
		while task.wait(config.regenDelay.Value) do
			if config.staminaCapacity.Value == 100 then
				print('stamina full')
				break
			else
				print('regenerating')
				loopPlaying = true
				config.staminaCapacity.Value += config.removePerSecond.Value
			end
		end
	end)

	if continuee then    
		coroutine.close(regen)
		coroutine.resume(cour)
	else
		coroutine.close(cour)
		coroutine.resume(regen)
		loopPlaying = false
	end
end

local ogWalkspeeed = humanoid.WalkSpeed

local function sprintOn()
	local runTween = ts:Create(humanoid,tweenInfo,{['WalkSpeed'] = humanoid.WalkSpeed + config.sprintSpeed.Value})
	runTween:Play()
end

local function sprintOff()
	local runTween = ts:Create(humanoid,tweenInfo,{['WalkSpeed'] = ogWalkspeeed})
	runTween:Play()
end


local function inputFunction(actionName, inputState, inputObject)
	if actionName == 'sprint' then
		if inputState == Enum.UserInputState.Begin then
			if config.staminaCapacity.Value >= 0 then
				sprintOn()
				staminaHandler(true)

				while task.wait() do
					if config.staminaCapacity.Value <= 0 or inputState == Enum.UserInputState.End then
						sprintOff()
						staminaHandler(false)
						break
					end
				end
			end
		end
	end
end

cs:BindAction('sprint',inputFunction,true,Enum.KeyCode.LeftShift)
cs:SetTitle('sprint','Sprint')

You can’t change a player’s walkspeed with a local script, you can only do it with a server script.

Server script overwritten old one
(While local can change)

#4

Make sure to add an InputEnded event to check when they release shift. Walkspeed can be changed by both the server and the client.
