Using LibGdx's extension for gamepads made it easy to support xbox-controllers.
But some nice soul should put up Keycodes for the buttons (They have made it for Ouya-controllers).
So after a little detective work I have the buttons and bumpers and DPad but not the joysticks, triggers, start and back buttons...
I also refactored so the x and y is in the center of the object.
So hacking away!
