How to touch part upon gamepass purchase?

Basically I want to make a part that gives more speed when you buy a game pass. I want the player to be able to change speeds so how can I make it that when someone buys a game pass it let's them touch the part, if they don't but the game pass they can't touch.

Hey there! If I understand your question correctly, then I believe that this is all that you need to do:

script.Parent.Touched:Connect(function(e) -- Detects touch
	if e.Parent:FindFirstChild("Humanoid") then -- Checks to make sure a player touched it
		local gamepass = 12345678 --Change this to your gamepass ID
		local player = game.Players:FindFirstChild(e.Parent.Name)
		local service = game:GetService("MarketplaceService")
		if service:UserOwnsGamePassAsync(player.UserId,gamepass) then
			e.Parent.Humanoid.WalkSpeed = 100 -- Change this to the speed you want
		end
	end
end)

Hope this helps!
