do you also know how i can get a SpawnTimer. Or can you change the code so my SimpleTimer can be used?

i want to make getWorld a static variable but i dont know how. is it even possible?

Why would you want to do that? If for an actor to access a field or method in your world class, you can just typecast what world is returned from using getWorld. Like so: <Code Omitted>If the actor can be in more than one type of world, you can check its type before typecasting it: <Code Omitted>

I need a list of fonts that can be used in Greenfoot. And because some people here are a bit slow, what I mean is a list of fonts just like in word or openoffice which I can choose from. I just want the names, preferably one which looks like pixel graphics. The API of greenfoot is horrible so any help is welcome.

Download my TextImage Support Class scenario. Then open it in your Greenfoot application. Do not run the scenario. The TextImage class has a listFonts method in it that can be executed manual
