The weird thing about Joystick.getPOV() is that it returns not booleans but an angle, in 45 degree increments. For example, if the user was pressing up on the DPAD, it would return zero. If the bottom and left buttons are being pressed, it would return 135. If no buttons are pressed, it would return -1.
I actually just wrote a
class today to handle this, though it might not be useful outside of our larger system.
