Heho,
I was just wondering why my joystick (XBox 360 controlller) was not sending any button input anymore even though I did not Change ANY code and to my great wonderment (does that word exist?) I found that GetKeyDown(JoystickButton0) was not sending true, while Joystick2Button0 was.
As I understand it, JoystickButton0 should be true if button 0 on ANY joystick is down?
I did not yet check if any other platforms are affected, I have that problem on my Win 8.1 RT device with an 8.0 build.
Best,
Thomas
