I was doing a sprinting system that uses a new animation, but idk how to make it to just plays when hes running and not when the player jumps. help

#

local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")

local MaxStamina = script.Parent:GetAttribute("MaxStamina")
local CurrentStamina = script.Parent:GetAttribute("CurrentStamina")

local RunSpeed = script.Parent:GetAttribute("RunSpeed")
local WalkSpeed = script.Parent:GetAttribute("WalkSpeed")

local Exhausted = false
local Running = false

local CanRunValue = 25
local RecoverRate = 2.5
local DrainRate = 6

local Player = game.Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Humanoid = Character:WaitForChild("Humanoid")

local AnimationsFolder = script.Parent.Animations
local Animator = Humanoid.Animator

local RunAnimation = Humanoid.Animator:LoadAnimation(AnimationsFolder.Run)

RunAnimation.Looped = true

local UI = script.Parent
local SprintBackground = UI.HolderFrame.SprintBackground
local Bar = SprintBackground.Bar

local function InputBegan(Input, GameProcess)
    if Exhausted then return end
    if Input.KeyCode == Enum.KeyCode.LeftControl and not GameProcess then
        Humanoid.WalkSpeed = RunSpeed
        Running = true
        if Humanoid.MoveDirection.Magnitude > 0 then
            RunAnimation:Play()
        end
    end
end

local function InputEnded(Input, GameProcess)
    if Input.KeyCode == Enum.KeyCode.LeftControl and not GameProcess then
        Humanoid.WalkSpeed = WalkSpeed
        Running = false
    end
end

local function UpdateStaminaUI()
    Bar.Size = UDim2.new(math.clamp(CurrentStamina/MaxStamina, 0, 0.991), 0, 0.614,0)
end

#

    if Running and Humanoid.MoveDirection.Magnitude > 0 then
        CurrentStamina = math.max(0, CurrentStamina - DrainRate * DeltaTime)
        UpdateStaminaUI()
        
        if CurrentStamina <= CanRunValue or CurrentStamina <= 0 then
            Exhausted = true
        end
        if CurrentStamina <= 0 then
            Humanoid.WalkSpeed = WalkSpeed
            RunAnimation:Stop()
            Running = false
        end
    else 
        CurrentStamina = math.min(100, CurrentStamina + RecoverRate * DeltaTime)
        UpdateStaminaUI()
        if CurrentStamina >= CanRunValue then
            Exhausted = false
            RunAnimation:Stop()
        end
    end
end)

UserInputService.InputBegan:Connect(InputBegan)
UserInputService.InputEnded:Connect(InputEnded)```

silk briar

Once input detected, check if its the right keybind then play the looping animation, One input is done being held, then Stop and Destroy the Track.

silk briar Dec 31, 2025, 5:31 PM

#

no

vapid ridge Dec 31, 2025, 5:31 PM

#

Make sure the Track is Global

#

And not inside the function

#

✌️

silk briar Dec 31, 2025, 5:31 PM

silk briar Dec 31, 2025, 5:32 PM

#

the problem is that when the player jumps, climb, freefall and etc the animation doesnt stop

vapid ridge Dec 31, 2025, 5:33 PM

#

Then check the states

silk briar Dec 31, 2025, 5:33 PM

vapid ridge Dec 31, 2025, 5:33 PM

#
