Calling vizard functions in a loop

[omidbrb]

Hi,

I noticed that if I call Vizard functions that have a visual effect in a loop, the commands wouldn't be run before the encapsulating function returns (even with delays in between) :

def callVizFunctionsInALoop():
	for i in range(0, 10):
		moveAvatar(i)
		takeSnapshot()
		#viz.waittime(someDelay)  #Won't help
		#time.sleep(someDelay)    #Won't help

Here, the snapshots will be taken as if the moveAvatar() function hasn't been run.

Is there any Vizard command that will get around this problem?

Thanks
Omid
