   Hi,

   I am new to cocos2d and i need to do pinball game so my first initial goal is that to implement moving ball with surface by surface with proper collision force. So i thought that i will get some help from Grabbed source code but i could not find that where they implemented collision portion when user moved any circles.

   Does anyone know that in which class they have implemented collision portion. Does anyone tell that how ball will move surface to surface in cocos2d.

   Thanks,
   iPhoneMobDev.

   All of the collisions and physics are managed by Chipmunk. All of the code is Grab.m itself, the initChipmunk is where the space is created, the bodies are added and the gravity is defined. The actual job of setting up Chipmunk is handled in the Helpers.m file. The rest, amazingly, is all handled by Chipmunk with very minimal effort on the part of Cocos2d. All that needs to really happen in the Cocos2d side is to have the step: function call cpSpaceStep().

   That's why it's a physics engine, it handles physics for you.
   Although you could implement a collision pair function. So in a specific collision you call upon a method.
