Making an object flash on and off constantly

[farshizzo]

The following sample shows how to use the viztask module to toggle the visibility of an object at a specified rate:

import viz
import viztask
viz.go()

model = viz.add('logo.ive',pos=(0,1,5))

def FlashTask(object,period):
	while True:
		yield viztask.waitTime(period)
		object.visible(viz.TOGGLE)
viztask.schedule( FlashTask(model,0.5) )
