it works fine. but i am trying to use the following lines to see the score

data = viz.Data()
yield viztask.waitEvent( viz.COLLISION_EVENT, data )

but this does not work with the following event detection

def onCollideBegin(e):
	if e.obj1 == rHandBox:
		if e.obj2 == box:
			box.color(colors.next())
viz.callback(viz.COLLIDE_BEGIN_EVENT,onCollideBegin)

any idea would be appreciated
