my clean up code:

Code:

         if(pRigidBody)
         {
            if(pColliderScene) 
            {
               pColliderScene->getDynamicsWorld()->removeRigidBody(pRigidBody);
               pColliderScene = NULL;
            }            
            delete pRigidBody;
            pRigidBody = NULL;
         }
         // delete pCollisionShape; <--- do i need to delete shape?

do i need to remove the shape i use in pRigidBody->setShape(pCollisionShape); ?

and if those shape are compound of other shape do they get deleted by the compound shape or do i need to store pointer to everything and delete them meeself?
:oops:

Indeed you should delete all the btCollisionShapes you use.
Of course you might reuse the same shape multiple times (e.g. when you scale them through a btUniformScalingShape, or simply when multiple bodies share the same shape) and you must be careful not to delete shared shapes too early.

I use a class that I've made that collects the shapes for me. I've posted about it long time ago (http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=9&t=5768&hilit=btCollisionShapeGarbageCollector), (although the most up to date version can probably be found in the source code of this project: http://bulletphysics.org/Bullet/phpBB3/viewtopic.php?f=17&t=7159&hilit=HACD).

P.S. It's not "the state of the art", but I find it very useful for my programs.
