I have chipmunk collision working and I have tested to the point where I can hide enemy sprite after collision. What I would like to do is, enemy hit animation after getting hit by projectile. What is the best way for doing this? Calling a method in GameNode class seems impossible... or I just don't know how to do it...
Any help or advise would be appreciated.
Thank you everyone.

You can call class methods inside C function. Check this thread:

Another thing you'd probably need is "freeing" your enemy from chipmunk simulation so you can do whatever you want with it (position/rotation).

Thank you for the information... I already had everything setup exactly as shown on the post, but it keeps on saying it "might not respond". I am posting my code for your reference. I am bit puzzled.
-(void) initCollisionDetection {
cpSpaceAddCollisionHandler(space, kCollTypeNinja, kCollTypeBall, collisionHandler, NULL, NULL, NULL, self);
}
static int collisionHandler(cpArbiter *arb, cpSpace *sp, void *data)
{
cpShape *a, *b;
cpArbiterGetShapes(arb, &a, &b);
GameNode *myClass = (GameNode *) data;
[myClass resetBall]; <----------- errors here 'GameNode' may not respond to resetBall.
return 1;
}
method "resetBall" is private method of GameNode Class. Please let me know if you guys need more information.
Thank you.
