   I have and still am open to considering open sourcing the project. My only concern are restraints on time for planning and coordination. Currently I work the project in pockets of free time. Previous open source efforts I've been involved with can sometimes absorb a good amount of time to reach success. I'd be open to suggestions though since my open source efforts have been limited. PM?

   Did you have any samples of the chipmunk in action for soft bodies? Mines ended up rendering pretty well but when you think about it there is a good amount of overhead in creating lots of slide / distance joints along with circle bodies.

   I was just planning on adding support for jellyphysics as an available framework within the IDE since it's full fledged soft body. Good amount of work probably to integrate but it works very similarly to box2d from what I can tell.

   @tato123 I think the open source would work well, but after you have a stable version. As you said yourself now you can just steal couple of hours every now and then and drive the code much forward by yourself thinking about the features on the fly. Just my thoughts :)

   I agree, a project needs general direction. I've only been a part of a couple open source projects and each generally has at most 2 or 3 high up contributors who for the most part drive the direction of the project and as each of the developers provide more value they have more and more say into the features that should be added. Generally though those 2 or 3 are charged with maintaining the basic roadmap.

   None the less, the project is going well now, it's progressing at a pretty steady pace. It's becoming more and more stable every day, most of the ground work is in place and coded and I'm now progressing back to the higher end levels like adding more physics bodies and hopefully joints soon. Beyond that I'll probably begin trying to find out who wants to give it a go and get some basic feedback.

   This project sounds really fantastic -- looking forward to seeing the results. This is the closest thing I've seen to what it sounds you're creating, thought it might give you some ideas for the UI: http://www.brainblitz.org/BoxCAD/

   @tato123: Can´t wait to test that baby! :) How is your project going at the moment?

   Thanks

   It's going along but i'm having difficulty with some cocoa bindings. I essentially have the document model that contains a collection which contains the physics groups. Within the groups I have a second collection that maintains the actual physics objects. I'm trying to use key value observing to figure out whenever changes are made to the objects themselves. The problem is I can't seem to observe a collection within a collection.

   I tried using dirty updates to register physics object changes but it was causing inconsistencies in the UI between how things were displayed versus what was actually contained in a project so I had to completely scrap that code.

   @marcotronic

   Long story short I'm having a stumbling block. Keeping changes in sync has presented a real challenge, I can generate code but I couldn't guarantee that what you have on the screen and the code generated were in sync. I'm soliciting help from the forums at the moment. Sorry for the constant delays on this one, beta build has been pushed back several times because of major bugs I found.

   I'm probably gonna start looking for additional help on this project since I need a second set of eyes checking some of the code.

   I plan to open source the project hopefully today or tommorow I will get everything loaded in source control. Sorry for delays on this, work decided 1 developer was enough to run 5 major projects, needless to say absorbed all my time. As a heads up the project makes use of bindings and is heavy on KVO. I've laid all the framework for the various engines, physics engine is abstracted and managed by a physics manager (implementation agnostic). Also project uses core animation for rendering to take advantage of video memory caching / buffering.

   Githubbed the project finally, so it's officially more or less open source, gonna see how this monkey can be wrangled so the cocos2d community to have a native mac physics editor. PS looking for help / contributors to start putting petal to the metal on this project :D

    Hi tato123,
    I cant not run your project due to some private library errors. But my question is just have you implemented soft Body dynamics ?

    soft body is not supported by box2d and chipmunk.
