In case anyone else stumbles across this thread in the future, the issue is that the Joystick initializer "stick (1, 3, 0) is specifying that the joystick has 3 axes. Then stick.GetTwist() is being called, which is axis 4.

The fix should be either changing the initializer to "stick (1, 4, 0)" or just "stick(1)"
