Hi,

I remember that IanM(I think) made a sprite collision code that was pixel perfect but I can't find it.

Does anyone know where I can get it?

Thanx.

From me

The first function will always work.

The second function is a lot faster, but doesn't always work correctly - I haven't figured out why

Woohoo!
Thanx alot, it works great, I just hated the crappy collision check of DBPro where it checks even the black bits of the sprites.

Thanx.

P.S. That was the quickest response I've ever had.

Hehehe... just curious, Ian. What is the trick behind those algorithms?

Shady, if you are using the first function, throw it away and use this one instead - I forgot that I made it slightly faster. Time to reorganise my code library I think!

Bullseye, I have added comments to the code in the code box that should explain what is going on.

You may find it easier to follow if you have a piece of graph paper and draw out the various scenarios.
