From using momentum you've got to apply all sorts of stuff like Newtonian Physics, restitution and that. I'll finish off my conversion of my version of Spacewar first, then I'll get to work. Getting a little off topic, now so here's another little problem: Is there an easy way of patching the keyboard to register a number of different keys (say 6) being pressed at the same time? Of course there is, but how is it done? James Arthur jaa AT arfa DOT clara DOT net
