I know, I post a lot of discussions. :/ But this problem I'm having just doesn't make sense. I'm using the GifActor (from this scenario: http://www.greenfoot.org/scenarios/260) to play the gif images, but they arn't playing unless I set the image inside the addedToWorld method. I really hope it doesn't have to be in the addedToWorld method for the image to work, because that would really bite! Does anyone know why it doesn't work?
