[comp.sys.amiga.programmer] Double buffering, page flipping

dalbec@sakura.ucdavis.edu (Gabe Dalbec) (04/03/91)

What is the best wat to do page flipping for double buffering a game.
I would like to still have a Screen Structure that can be flipped back
and fourth with Amiga-M and N.  It does not have to be draggable, but
should be able to be seen when annother screen is dragged down.  I am
currently using ScrollVPort, but that flashes and jumps ocassionally.
What exactly is ScrollVPort doing, can I write a routine to do that?  I
know that it is updating the copperlist, but I need more specifics on
how to do this.

Thanks,
-gabe
