state = JoyHat(port[, idx])
port. Joystick hats are also known as point-of-view
d-pads. The returned state will be -1 if the hat is in the center,
otherwise a value between 0 and 27000 will be returned. The optional
argument idx can be used to specify the index of the joystick hat to
use in case there are multiple hats on a controller. Indices start at 0.
port can range from 0 to the number of joysticks currently plugged in
minus 1. You can find out the number of joysticks currently available
using the CountJoysticks() function. Please note
that under AmigaOS, port 0 addresses the standard joystick port although
this is port 1 on classic Amiga hardware. Hollywood switches these ports
for cross-platform consistency where port 0 shall always refer to the
default joystick.
