Another Joystick Question

[farshizzo]

Hi,

The upcoming version of Vizard will allow you to create callbacks for joystick buttons, but for now you'll have to manually check when a button is first pressed. Here's a simple example:

import viz
import sid

viz.go()

laststate = sid.buttons()

def mytimer(num):
	global laststate
	state = sid.buttons()
	if state & 1 and not laststate & 1:
		print 'button pressed down'
	laststate = state

viz.callback(viz.TIMER_EVENT,mytimer)
viz.starttimer(0,0.001,viz.FOREVER)
