Chipmunk Physics

Hi,

my name is Andreas Loew - and I created a new tool for chipmunk - http://www.physicseditor.de

Its a shape editor for sprites with editing capabilities for physics parameters. Simply import the sprite, press the auto trace button and edit all parameters you want.
PhysicsEditor handles convex/concave polygons and orientation for you.

Here's also a short video showing how to use it with corona sdk: http://www.youtube.com/watch?v=EZT1lrxVut4

Another key feature is the generic exporter format. You can export the data in nearly all formats your want - from source code to XML - just exactly what you need.
The default export format currently is XML/PLIST but I might also other ones on request.

Cheers
Andreas

I've been working on some similar code to use for a few months: http://howlingmoonsoftware.com/wordpress/?p=409

It's really modular at this point. You can string together a few operations into a processing pipeline, the problem is that it's pretty low level. To trace an image you have to create a sampling function and a segment callback. This makes it configurable enough to do everything from high speed deformable bitmap terrain to dynamic creation of shapes when loading sprites. Really all I have left to do is create a few simple functions to wrap the usual cases. I really need to get that done and make some examples. Too many things to do in a day!

I updated chipmunk integration and added a sprite factory which allows to drag single bodies from a file.
Would you be interested in adding this to your Objective-C loader?

Plugins for modifiying other functions or adding functionality would be cool.

@andreas.loew: Oh shoot, I must have missed that post in the hustle and bustle of GDC. Yeah, that would be cool. I could hook you up with a copy in a couple weeks once our current contract work dies down.
