removing multiple objects

Hello,

I cannot figure out how to remove or delete multiple objects that have been created this way:

Code:

        def balls():

                ball = ballOriginal.copy()

                ball.scale(.5,.5,.5)

                ball.collideSphere()

                ball.setPosition([0,20,0])

        vizact.ontimer2(0,200,balls)

How can I remove all 200 of those balls?

Thanks

You should save each object you create into a global list. Then you can periodically go through the list and remove the objects.

Is there a good example of this to follow?

I'm not sure there is an example that does exactly what you want, but the Duck Court example script that comes with Vizard shows how to save objects into a global list so they can be referenced later.

Code:

        

ballList = []         



def balls():

     ball = ballOriginal.copy()

     ball.scale(.5,.5,.5)

     ball.collideSphere()

     ball.setPosition([0,20,0])

     ballList.append(ball)

vizact.ontimer2(0,200,balls)

So I added a global list... how do you "periodically go through the list and remove the objects"? I tried ballList.remove() and that didn't work.

I'm not sure if I understand exactly what you want to do, but if you first make the global list and then want to take all the balls out of it, you could:

Code:

for row in range(len(ballList)):

                ballList[row].remove()

which will cycle through your list and remove each item.

Or, you could just erase your list by re-initializing it (I think):

Code:

ballList = []

Ok I will give that a try later... thanks for the feedback

Great I think it worked.
