[SOLVED] setLocalScaling makes box fly

[pfanne]

Hi there,
I have the following issue:
When I shrink a box, via setLocalScaling() it will not drop to the ground, until it is affected by a collision with another object, or a constraint.
I tripplechecked and the object is active.

Help with this would be much apreciated.

I have found a bullet issue which explains a more or less similar situation, maybe the information there could also help you, please take a look at it:

https://code.google.com/p/bullet/issues ... %20Summary

There Erwin states:

Before you make any change to the collision shape (replace shape, resize etc) you need to

1) remove the rigid body from the world
2) make the change (resize etc)
3) re-insert the body into the world

Alternatively you can flush the contact points manually for the object involved:

dynamicsWorld->getBroadphase()->getOverlappingPairCache()->cleanProxyFromPairs(body->getBroadphaseHandle(), dynamicsWorld->getDispatcher());

Hope that helps.

works nicely.
thanks.
