Answer by Kiyaku

I tried it with a PS3 controller once. I had to:

• Find a driver so Windows can recognize the PS3 Controller
• Go to the GameController Settings in your Windows Systemsettings
• Calibrate your controller (it is useful to write down which button is assigned to which number)
• And use KeyCode.Joystick1Button0, KeyCode.Joystick1Button1, ... in Unity to get the Input.
