Chipmunk2D Chipmunk Pro is now free and open source and included in Chipmunk 7! Penguin in a Shopping Cart uses Chipmunk2D to bring smooth and fun motion to his journey. (Video) Reassembly's destructive combat and huge interactive world is driven by Chipmunk2D. Chipmunk2D is the official physics engine of Cocos2d, featuring full Objective-C integration! We have many Cocos2d tutorialsboth for free and Pro Chipmunk2D. Pentumble creates a physically interactive world in their cross-platformgame driven with Chipmunk2D. Chipmunk2D has been usedin hundreds of games andon many platforms. and it's awesome Waking Mars brings a lush world to life with the help of Chipmunk2D. Creatures are procedurally animated using joints. Chipmunk2D powers the rigid body dynamics of Feed Me Oil, which reached top spot on the App Store. Quick Links

Want to throw a logo on your splash screen to show how much you appreciate Chipmunk2D? Frank Condello was gracious enough to make a logo for me. A couple variations are available here.

Acknowledgments:

• Erin Catto:
Erin Catto's Box2D code was the most useful reference that I used when creating Chipmunk. His contact persistence algorithm is the main reason why Chipmunk2D is so fast.
• Optimized Spatial Hashing for Collision Detection of Deformable Objects
The best article I could find on spatial hashing. Their hash function seems to perform very well.
• Nonconvex Rigid Bodies with Stacking
My previous implementation was based on this paper. I only implemented part of the algorithm before deciding that something simpler would be better suited for real time. I do use the split elastic solving pass in newer versions of Chipmunk2D however.
• Physics for Game Developers
This book is a good reference for a lot of the math you'll need, but is far from a good reference on implementing a physics engine.
