More Box2DAS3 v2.1a Progress

Ok, the first revision (r52) of Box2DAS3 for the next version is available now on SVN. Phew, that was a lot of work.

Lots of stuff doesn’t work, but the reduced testbed ought to compile and run.

The old SAP broadphase works, as well as Dynamic Tree.
It’s 3-4x slower than the old version! It’s because I replaced some of the old optimizations with newer more naive code. It’ll improve over time as we re-inline stuff and so on.

What should you (the casual Box2D user) do now:

  • Still nothing. It’ll still be some time for the port to catch up with C++, and get cleaned up. And there’s the performance issue. I wouldn’t recommend moving unless you have an essential reason, or have a project that you are keeping continuously up to date.
  • I’ll be accepting patches now to lighten the work load, if anyone at all is keen. Post them on the forum, preferably declaring your intentions in advance. All patches must be under submitted under the same zlib license. They must be actual patch (diff) files. Updating the testbed examples would be a good excercise for someone keen to try out the new API.
