TheDevil'sCompass Posted March 7, 2022 Share Posted March 7, 2022 Does anyone know how the iris screen wipe/reveal between levels in Lode Runner is done? I'd like to do something similar on the Sega Genesis using SecondBasic. My 6502 assembly is beyond rusty at this point so diving into the source code wouldn't help me much. An Applesoft example would be great (even if it's slow as molasses) or even a good explanation as to what is going on would be appreciated. I feel like I'm missing something simple since the wipe works at a pretty decent clip on a relatively slow machine. It seems to me that it is drawing a ring at ever increasing steps until the screen is filled as opposed to redrawing an ever increasing filled circle. I just haven't been able to wrap my head around the mechanics of how it is accomplished. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
