using i900 joystick in a taskFunction

[krimble]

Hi,

What I'm trying to do is, using the buttons on the joystick to scale my virtual world. I'm using a task know, but it seems that the event doesn't get triggered when using "viz.SENSOR_UP_EVENT". If I use "viztask.waitSensorDown" then I don't know what to put in it as a button. I've tried the state things from the manual "joystickSensor.get()[7]" but it doesn't give me the actual pressed button wich I have to put in, right?

def scaleOnSensorEvent() :
	dataObject = viz.Data
	sensorData = joystickSensor.get()

	while True :
		yield viztask.waitEvent(viz.SENSOR_UP_EVENT, dataObject) 
#		yield viztask.waitSensorDown(joystickSensor, button??, dataObject)
		print "something"

if viz.get(viz.TRACKER):

	headSensor = viz.add('intersense.dls')
	viz.tracker()
	headSensor.reset()

	joystickSensor = viz.add('intersense.dls')
	viz.tracker()
	joystickSensor.reset()

viztask.schedule(scaleOnSensorEvent)

thanks for your help
