So I do not know what I am doing wrong but I set the collision group of “Player” off but nothing works.

Here is the code:

local PS = game:GetService("PhysicsService")
game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		for i, object in ipairs(char:GetDescendants()) do
			if object:IsA('BasePart') then
				print("works")
				PS:SetPartCollisionGroup(object, "Player")
			end
		end
	end)
end)
