The Graphics Magician disk has all the software needed for drawing on the dbl-hi-res screen and includes animation routines. The game "Black Cauldron" uses the graphics and animation routines from the Graphics Magician disk.
To try to understand graphics and animation in dbl-hi-res takes more than one session. Nibble magazine has a 10 part series including animation routines that explains it pretty good.
Nibble magazine also published and article called "Double Stuff" including software that uses normal hi-res shape tables for animation.
I wrote an applesoft program that allows you to plot on the dbl-hi-res screen. But animation is a little more complex.
