Roblox Script Generated by ScripterAI

"make it so players load in with a custom front walk when pressing W and a custom back walk when pressing S where do i put it"

You should put this script in a LocalScript inside the StarterPlayerScripts folder. Here's the script:

```lua
-- LocalScript inside StarterPlayerScripts

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

local customFrontWalkAnimation = Instance.new("Animation")
customFrontWalkAnimation.AnimationId = "rbxassetid://YourFrontWalkAnimationIDHere"
local customBackWalkAnimation = Instance.new("Animation")
customBackWalkAnimation.AnimationId = "rbxassetid://YourBackWalkAnimationIDHere"

local frontWalkTrack = humanoid:LoadAnimation(customFrontWalkAnimation)
local backWalkTrack = humanoid:LoadAnimation(customBackWalkAnimation)

local function onMove(input, processed)
    if input.KeyCode == Enum.KeyCode.W then
        frontWalkTrack:Play()
        backWalkTrack:Stop()
    elseif input.KeyCode == Enum.KeyCode.S then
        backWalkTrack:Play()
        frontWalkTrack:Stop()
    end
end

local function onStop(input, processed)
    if input.KeyCode == Enum.KeyCode.W or input.KeyCode == Enum.KeyCode.S then
        frontWalkTrack:Stop()
        backWalkTrack:Stop()
    end
end

game:GetService("UserInputService").InputBegan:Connect(onMove)
game:GetService("UserInputService").InputEnded:Connect(onStop)
```

Replace "YourFrontWalkAnimationIDHere" and "YourBackWalkAnimationIDHere" with your custom animation IDs.
