I'm going to have to agree with everyone so far that you've done a good job on collecing information on how to program for the Atari 2600. Keep this up and you can release a "Dummies Book". For me, this information is invaluable. With my degree in Comp. Science, I just love picking apart programs and understanding how and (more importantly) why they work. Now to put my piece of paper to work here, using my knowledge of assembly and micro coding (IE: One step below assembly): > Is the usual way of doing this something along the > lines of: > (in Pseucode) > > IF SCANLINE == VERT POSITION OF MISSILE > TURN ON MISSILE > SET REGISTER OR COUNTER TO MISSILE HEIGHT > END IF > IF MISSILE REGISTER/COUNTER IS ZERO > TURN OFF MISSILE > END IF > DECREMENT MISSILE REGISTER/COUNTER > > Or is there a cleverer (yet not too devious and hard > to understand) > method of doing this? The safest way to go about this is to do the long way. Shorten it down, if possible. It's always better to overcode then undercode. The last thing you want is to miss a crucial step. __________________________________________________ Do You Yahoo!?
