Is it possible to make the world move instead of the actor; I'm trying to create a game which is in a world that is too large to fit on the screen. So I want the world to move under the actor.
There isn't any way to make the world move instead of an the actor, but what you can do instead is create the illusion of World movement by moving *all* actors in the opposite direction that you want the world to move in.
Yeah, that's what I was thinking, my problem is how to map it in a way that, if I return, it will show the same thing. I found the "city" project, I'm going to see if I can see how they did it.
For example, if I was playing a game, I would be able to go someplace, walk away from it, and when I walk back to it again, it will have the same stuff there.
As long as you make your Greenfoot world an open world (it's an option in the constructor) objects will be able to move anywhere (including off the screen) without a problem.
