As you can see I don't have a lot of posts(!) because I use GD (but considering moving to something else due to 2.05 licensing terms
)
Your articles deals with sprite collision.
I do agree with Thierry (BTW: are you french?) that sprite collision should not be too low level. It could be used for lots of things not all directly linked to graphics :
- Compute dirty area
- Compute new speed vector for an object due to collision
- "Normal sprite collision" (death of heroe - You!)
I just submit this samll articles that was written by ... Micro$oft !
I have found this one interesting because for any pixel to pixel compares it is precomputing the "interesting" rectangles to check for.
I think it's also interesting for newbies to read this one because it explains a lot of tips and tricks.
I hope that it might be helpfull for anybody and that once in a next release we could find sprite-like class.
Bye
