Hi,
I just found PocketFrog and am interested in the pixel shaders. I see that you can get the color of the source and destination pixels within the shader. Is there an easy way to get the current pixel's screen (x,y) location?
I made this:
If you look at the source you will see that I did a cheap trick to maintain a pixel cursor during a fragment run. This only works with non-masked rectangular sprites though.
Thanks,
Neil
