VGA

VGA

(OP)
I want to make a cool little screensaver using assembly language and its VGA graphics mode....

i would like to make something like that microsoft butterlfly...

nothing too fancy, just allowing it to fly straight until it hits an edge of the screen, then just "bounce" off and fly straight ahead again...

and of course like a regular screensaver, it will exit the screensaver when i press a key..

can anyone give me some hints on how to start??

thanks in advance...

RE: VGA

Buy a book on graphics programming.  A rather oldish book on VGA programming preferable.

Most books will be on graphics programming in C, but you can probably hand-compile it yourself with some optimizations.

Learn how to use cmp.

Learn to figure out how to do delays.

RE: VGA

It used to be on Doctor Dobb's Journal (www.ddj.com) but it no longer appears to be there... 404 file not found...  You COULD try maybe it's just temporary...
