My apologies for posting so much code here. Please let me know if this frowned upon.
I wanted to start a new thread that is related to my previous "How can I profile basic functions for the RP2040?" thread.
This time, I am drawing tiles instead of sprites. In my other topic, Adam was able to drastically help me speed up my sprite drawing routine. I went from 14 sprites per scanline to 24.
I also have a tile drawing routine that is almost identical to the sprite drawing. So I assumed putting the same logic there should speed that up as well. But it actually had the opposite effect!
The difference between sprites and tiles is that the sprites can move freely while the tiles are fixed on 16 pixel boundaries. Also, tiles do not check for color 0 so they should be even faster.
Below you will see three different versions along with their assembled code.
I would love to know why the sprite trick for optimizing didn't work for this tile code.
The odd part is that "Optimized 2" is ALMOST as fast as the original but still larger.
Thanks for any feedback!
