I have looked around the forum to try and understand the below from Princess Rescue and other games I have seen. How does one calculate the data below to create levels and make it scroll left, right, up, down etc.? I know about pfscroll but that is very repetitive (but useful at times). Basically if there is a demo with some notes stripped to the "bare bones" for moving left to right and backwards then I (we) could learn from it. Then another for up and down. Then another for open world in the kernels that would be great. I think the Multisprite is not feasible because of the mirrored playfield unless you use "brute force" a Bogax saying in one of his post to make it look like a single pixel was on and off. The others I think can be done. Thoughts? Thanks.

Not a full answer due to time of night here :)


I think there are several topics to explore.  You best bet is in topics which bogax helps with regarding 4 way scrolling.  Also, you can fake smooth horizontal scrolling with the multi sprite kernel.




I know nothing about the DPC+ kernel.  Maybe by now it supports scrolling.

Thanks. I have used both. I used your when I started making (The Quest) a sub game with the Sprite seaQuest. The data is what I'm interested in. I plan to play with this weekend if I have time to see if I can make sense of it. I did use Bogax as well.
