Calling vizard functions in a loop

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) :

Code:

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

You should be using the viztask module. There are many examples of it in the docs and on the forum.

Code:

import viztask



def callVizFunctionsInALoop():

        for i in range(0, 10):

                moveAvatar(i)

                takeSnapshot()

                yield viztask.waitTime(someDelay) #Pause function for some time



viztask.schedule( callVizFunctionsInALoop() )
