local debounce = false 

function onTouch(part)

local human = part.Parent:findFirstChild("Humanoid")
if (human ~= nil) and debounce == false then
debounce = true

local id = 7549271

game:GetService("MarketplaceService").PromptGamePassPurchaseFinished:Connect(function(plr,ido,purchased)
    if purchased and ido == id then
        plr.Character.Humanoid.WalkSpeed = 40
    end
end)

game.Players.PlayerAdded:Connect(function(plr)
    plr.CharacterAdded:connect(function(char)
        if game:GetService("MarketplaceService"):UserOwnsGamePassAsync(game.Players[char.Name].UserId, id) then
            char.Humanoid.WalkSpeed = 40
human.WalkSpeed = 40
