Kevin, I've just tried to use the pixel perfect sprite code that you posted a while back, and I get a "Not enough parameters for the "compareSpritePixels" command. I'm using PB 1.46

The command in your code reads - CompareSpritePixels(spr,spr2)

I presume this has been updated, but I can't see the correct usage in your updates here.

What are the correct parameters now?

Ian, CompareSpritePixels(spr, spr2, precision#) where precision is a float between 0.0 (lowest precision) and 1.0 (highest precision). Kevin says 0.5 is good enough most of the time - I would just trust him  :D

Cheers :)

I'll have a play with later.
