I need help making all players walk throughable?

This is what I have but no luck. It also worked if it was removing there arms.

game.Players.PlayerAdded:connect(function(player) player.CharacterAdded:connect(function(character) character:FindFirstChild("Head").CanCollide = false character:FindFirstChild("Left Arm").CanCollide = false character:FindFirstChild("Left Leg").CanCollide = false character:FindFirstChild("Right Arm").CanCollide = false character:FindFirstChild("Right Arm").CanCollide = false character:FindFirstChild("Torso").CanCollide = false end) end)

Like in this game. http://www.roblox.com/games/230362888/The-Normal-Elevator

Hi I'm on mobile so I can't test this but i have another solution for this. Simply make all the parts canCollide = false

for i,v in pairs -- this is making a for variable so we can make v our get children variable.
(game.Workspace:GetChildren()) do -- this is getting all parts in workspace
v.CanCollide = false -- this is making t false

Like I said I'm on mobile but it should work let me know if it did or didn't
