Issue taking away stamina

[V0RTEXwhoEditz]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I’m currently making a system with running, dashing and double jumping.

2. What is the issue? Include screenshots / videos if possible!
   For some reason, there are no errors in the output, but it doesn’t take away any stamina when I slide. (I haven’t added the stamina part to the other movements yet.)

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I have tried the devforum.

My slide script.

local UIS = game:GetService("UserInputService")
local char = script.Parent
local humanoid = char:FindFirstChildOfClass("Humanoid")
local rootPart = char:FindFirstChild("HumanoidRootPart")
local canslide = true
local keybind = Enum.KeyCode.V -- Key to activate slide
local Stamina = game.Players.LocalPlayer:GetAttribute("Stamina")

local slideAnim = Instance.new("Animation")
slideAnim.AnimationId = "rbxassetid://77407259532005" -- Enter your Animation ID

-- Function to check if the player is moving downhill
local function isGoingDownhill()
	local rayOrigin = rootPart.Position
	local rayDirection = Vector3.new(0, -5, 0) -- Cast downward
	local raycastParams = RaycastParams.new()
	raycastParams.FilterDescendantsInstances = {char}
	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist

	local result = workspace:Raycast(rayOrigin, rayDirection, raycastParams)

	if result then
		local normal = result.Normal
		local slopeAngle = math.deg(math.acos(normal:Dot(Vector3.new(0, 1, 0))))

		return slopeAngle > 10 -- Returns true if the slope is steep enough
	end

	return false
end

UIS.InputBegan:Connect(function(input, gameProcessed)
	if gameProcessed or not canslide then return end

	if input.KeyCode == keybind then
		canslide = false

		local playAnim = humanoid:LoadAnimation(slideAnim)
		playAnim:Play()

		local slide = Instance.new("BodyVelocity")
		slide.MaxForce = Vector3.new(1, 0, 1) * 30000
		slide.Velocity = rootPart.CFrame.lookVector * 85
		slide.Parent = rootPart

		-- Minimum slide time for flat surfaces
		local slideTime = 0.8 
		local elapsedTime = 0

		while elapsedTime < slideTime or isGoingDownhill() do
			wait(0.1)
			slide.Velocity *= 0.985 -- Reduced friction for longer sliding
			elapsedTime += 0.1
		end

		playAnim:Stop()
		slide:Destroy()
		canslide = true
		Stamina -= 10
	end
end)

You need to use :SetAttribute() when modifying an attribute.

-- this just gets the value of the attribute
local Stamina = game.Players.LocalPlayer:GetAttribute("Stamina")
...
...
    --Stamina -= 10
    local CurrentStamina = game.Players.LocalPlayer:GetAttribute("Stamina")
    game.Players.LocalPlayer:SetAttribute("Stamina", CurrentStamina - 10)

Rightt! My brain wasn’t turned on when I was scripting that
