2. It is a relict out of old times, as I began to program this. I wanted to add a multiplayer, but I haven't worked on that yet.
It isn't as hard, as it seems. Look here, it's a tutorial from one of the greenfoot-programmers, whose name on this site is Mik:

There are two parts of it and it's very well made.
