I made a GUI that is both Xbox and PC compatible. When you play on the Xbox, Xbox buttons manage the GUI and when you are PC "MouseButton1Click" manages the GUI.
Is there a script where the game can detect if you are on PC or Xbox and make certain scripts work if you are PC or Xbox?
You can get the platform and then run the script using an If Then. Here's some more information on how you would do that http://wiki.roblox.com/index.php?title=API:Enum/Platform
