Collision functions or handlers get called twice always

[samueller]

I tried posting this issue to the chipmunk-physics forum:
http://chipmunk-physics.net/forum/viewtopic.php?f=1&t=2402&p=10566

My collision functions or handlers are always called twice for every collision.

The version of chipmunk that the Ruby wrappers wrap is quite old, but what you describe seems to work just in the same way in the old C version. So I don't know if there is anything I can do for you. :/

The author of Chipmunk wrote this in that thread: "I'm beginning to suspect it might be a bug in the Ruby binding maybe."

Is this bug still active?

It seems like pull request #17 should have fixed this issue, and that pull did get merged in.
Would be nice to have official confirmation.

(notifying @shawn42 , because iirc beoran hasn't really been working on this project for some time now)

The short answer is that there was no failing test-case for this. @samueller or @mirichi should probably close the circle on this and either submit a test case, or confirm that it is working for them.

Thanks for following up on this @RavensKrag
