Insert 'if(avatar != null)' in line 21 in the Enemy class to check if the intersecting avatar exists. Only this one line is missing :)

5 MB LocalStorage: enough for saving the image ;) Feel free to look at the source code; doc: http://metropy.net/greenfoot3d/doc/

I tested it, its working in standalone jar, too ; Greenfoot3D is a non official Greenfoot 3.0, with a lot of cool stuff ;) A early beta version is available, somewhere in the discussion forum... I already implemented the 3d World, and the EndlessWorld stuff; I am currently working on 5MB scenario storage; Custom Controls; and 'Export to Android' When i am done, the final Greenfoot3D will be released :)

@Kartoffelbrot: - World.centerTo(Actor) <- center world to actor - World.setEndless(boolean) <-change endless state - World.boundActor(int) <- make sure actor is visible (ni) - Actor.isVisible() <- is Actor visible (ni) - Greenfoot.requestFullscreen() <- make world fullscreen and the 'FullScreen' button. (PS: The use of ubounded worlds is required for 'Export to Android APK'; - for fitting into every screen/device size) @pkramo: Look under the 'Open in Greenfoot' button; this is a Greenfoot3D scenario. It will only run using Greenfoot3D.
