How can I make a brick that when you step on it it gives you a tool, but if you already have that tool in your inventory, it doesn't give it. Also a brick that removes just that tool.
if player.Backpack:FindFirstChild("ToolName") then player.Backpack.Tool:Destroy() else new = Tool:Clone() new.Parent = player.Backpack end
That is what you may use, just fit it in your script. (If you don't know how, follow zMatrix65831 suggestion and learn it before using it)
