Assert in DynamicAABBTree.h

[andreasdr]

Hi,

i have a new assert which popped up today.

• Assertion failed: (mNodes[nodeID].isLeaf()), function getNodeDataPointer, file ext/reactphysics3d/src/collision/broadphase/DynamicAABBTree.h, line 285.

I guess it happens after adding/removing a body.

The full backtrace looks like:

However if disabling assertions everything works as expected.

Thanks for reporting this.

I am not able to reproduce this. Do you have some code that I can run with this issue ?

[andreasdr]

Hi,

Will try to set some code up. It will take some time though.

Best regards

Hi,

is it possible that this dissappeared with fix of #60 or another one? I was not able to reproduce it today.

Many thanx and

Best regards

Hi,

Yes, it might be related. Do you have a test where this bug can be reproduced in your code so that I can check if it has been fixed by the patch for bug #60 ?

[andreasdr]

Hi,

did not come up with a test until now. Wanted to create one today after #60 has been fixed.
Tested with our game. It disappeared. :)

So I guess its gone.

Many thanx and

Best regards
Andreas

Ok thanks. I am closing this issue.
