As the next Greenfoot release nears, and I mentioned sound support in my last post, there’s now a short demo video available. It shows smooth animation, and sound support in Greenfoot (in an “Asteroids” scenario).
Watch it here.

And come the next Greenfoot release, do it yourself!

And the best thing about it (or at least one of the best): this whole program is written with only about 280 lines of code (in Java)! Not too bad, I reckon.
