Chipmunk Physics

I upgraded to 6.1.2, and now it seems rotational friction on the multigrabber isn't working, though I'm not certain exactly what the root cause is. Previously, if I grabbed a ball and bashed it against the wall it didn't rotate at all. Now it'll begin spinning. Every grab after that will spin as if there was no rotational friction.

Here's an example.

Some help would be appreciated. For now I've reverted to the previous release.

Hmm. There was a something I changed related to the grab queries. I may have broken that... I'll look into it! Thanks for the bug report.

Ok, I fixed it in the Chipmunk Pro git repository. There is information here about how to checkout the code if you are Chipmunk Pro customer:

I'll put out a fixed build soon if that works for you.
