Hey!

In one of my current 'projects' (it's more like playing around with new stuff) I'm using 2D sprite graphics and I really need some kind of collision system.

Has anyone got some information (examples/tutorials) on how to code a 2D collision system, or any idea how I could solve this problem?

kind regards, Kartoffel

i would use a 2d physics engine like box2d or chipmunk. then you don't only get collision detection but nice physics too.

i think chipmunk uses a c-api so maybe it is directly usable with lite-c.

oohh, why didn't I notice this, thanks a lot ^^'

afair, someone coded a box2D wrapper for the AUM-contest some time ago, I'll have a look at it

Edit: yep, here it is

jip I guess it depends on your needs , the one I did
with per pixel collision pretty much would do for
any kind of 2d collision detection if rotation
were apart of the check,of a sprite based game .

mine is a bit like "sonic the hedgehog" .

no physics though ,only detection of pixel intersections .

I have been looking at the marching squares algorithm for finding the outline of objects in images
wich could then be used to form physical bodies with
in libraries such as the above mentioned physics libraries .

that would enable me to turn 2d drawing into physical objects .

having the outline also enables a lot od other useful functionality .

but any way ,good luck and enjoy .
