Hi!
I'm quite new to bullet and haven't really learned the design yet. I'm trying to find out when a body have stopped moving. From what I understand, this is called that the body has fallen into sleep. Is there some way to get a callback when a specific body has fallen in sleep? The reason is that I want to be able to drop a body and then get the final position of the body.

You can edit the source code for that.
You should only need to edit two functions that would call the callback, and add a function which adds a callback pointer on rigid body or collision object.

Be aware though that if the callback pointer goes bad, you'll have a segfault.

Hi! Editing the bullet source is not really an alternative for me. So I guess I'm stuck with testing the body until it stopps moving. Tried that yesterday. One problem I have is that it is not really clear how to test if the body acutally has stopped moving. btCollisionObject::getActivationState does not seem to do the trick. I have tested it's return value with ISLAND_SLEEPING and it didn't trigger.
Does anyone have any good tips on how to do this or an tutorial about moving states?
