Of course this post isn’t for everyone, but if you ever are in need of a physics engine in your game (or app for that matter), I can’t be more thrilled with the Chipmunk Physics Library, written by Scott Lembcke, over at Howling Moon Software.
It’s a 2D Physics Simulator, which I originally used years ago on BocceBeers, and with this latest upgrade, am using again. The most important thing I find with 3rd party libraries (beyond doing what they say they can do), is documentation, examples (there are PLENTY), and support.
I have no idea how the author of this lib has the time to develop, market, and support his library, but whenever I post anything to the forums, he’s got it answered within 24 hours. Every time. It’s so amazing to not have to get stuck on a problem and wait for the developer to get back to you. (Ever had a problem with Twitter on iOS… man…)
Anyway, go check it out for yourself. There are some pretty videos. 🙂
