So I just made http://www.greenfoot.org/scenarios/4074 but it only magnifies the world's background image, and if you go over any actor's it'll act like they're not there. That's because I don't know how to get an image of the world as a whole, including actor's currently in the world, and I'm looking for a (hopefully nice and simple) method of getting that.
Actually, I've just had an idea, but while I try that (and its looking complicated >.<) please post away
