|  Programming Sprites like on the Vic-20-Souce Code included
The Vic-20 uses the same technique to move soft sprites(custom characters) as the c16- Plus 4(except bit map mode). I know some assembly(no expert though, can someone transfer this code so it works on the Plus/4-c-16.
Thank you 
How to display bitmapped graphics.
Bitmapping is a flexible technique that makes sprite animation look really smooth. A lot of ROM games (Examples: Jetpac, Turmoil, Fast Eddie, Gorf, Shamus, Predator, Black Hole, Ms. Pacman, Demon Attack) use bitmapping, though it does cost a lot of memory. Of the unexpanded 5K RAM that is normally available, less than 1K is left for variables or code. I have written a little program (Source, PRG image) that explains the use of bitmapped graphics.

Funkydude, this technique is well known on the Plus/4 and is widely used. "Sprites" on the C=16 & Plus/4 are really nothing but bitmap (or character) graphics. Take a look at Solo Spriter for example for a free usable-from-BASIC sprite routine + editor. There are a few others as well.

You done any coding with this Csabo? It would be neat to write classics that were not ported to the plussy. I know 6502 ML and some TED stuff. Did it in junior high school.

@funkydude:
Why do not try my MegaAssembler?
