Help for my new game.

Batari Basic To avoid thinking too much what's the best way, for example, if we have player1 and two of his copies (NUSIZ1=$3), to hit the back copy with a missile, while the first two remain, or hit the middle one and the two on the sides remain, etc. How to do this mathematically and programmatically in the best way?

Secondly, is it possible to have multiple missiles without flicker? (DPC+)
In fact, what is the best way to have multiple missiles on the screen?

This chart will help a lot:

It shows all the values of NUSIZx.

There are only 2 missiles and they are weird when using DPC+.

This link with an example of shooting in copies is probably what I need; I hope it's easier than how I started doing it
 

The missile thing disappoints me; I don't like Flickr, but if there's no other way, then it will have to do however it can.

Thank you for the help.

Thank you for the help.

Remember you also have the ball, for 3 missiles as it can be programmed to collide with anything too. Don't use multi color kernels.

 

Remember there are only 9 combinations of 3 copies - 1 of them. You can just program the collision to redraw them as one of the appropriate remaining 8 combos, with proper x offset.
