I've been working with Advan Basic for a few months and really enjoy it. The commands for player-missile graphics are much easier to use and faster than those in Atari Basic. One part I can't figure out is collision detection. The Advan Basic manual says the command T%=COLL(2%,16%) returns an integer whose value depends on whether or not player 2 has collided with other players. This sort of works for me, but I still stuck on getting it to work properly. What should the value of T% be if there is a collision? If I PEEK location 53260, which I think is the collision status of player 0, it returns 12. I want to do an IF statement where IF T% is the value of a collision, then do something. What number should I look for?
