Multi-Color Sprites?

Recommended Posts

Hi,

 

from the Atari 800XL I know there is an interrupt for every scanline of the screen. Is there something similar on the TI? Perhaps there is already a ASM-Routine that can change the color of a sprite like in H.E.R.O for some selected sprites on a line-by-line basis? I think 4 of the 28 sprites in multi-color would be beneficial for many games and not too much overhead, considering this scanline-interrupt being extremely time-sensitive...

No there isn't. But you can stack multiple sprites, and if you offset them vertically it takes a little longer before you run into the 4 sprites per line limitation. One more option is to add an additional color using background patterns, like the ghosts' eyes in Ms. Pac-Man.
