Hi, I've tried to let it snow in my game, but then I get java heap space errors, because Greenfoot isn't able to display all the snow I want to add to the world. So now, I'd like to add a gif file as background so that it can snow. Here's the link to the file: http://www.archiv.allkaemper.de/bilder/in_foren/Schnee.gif In Greenfoot, there is a Helper Class I've used now. But when I set the file as background there is nothing else than this picture. So my question now is: How can I use the gif file as backgrund like the one I had made on my own?
