problem with btRigidBody and btGImpact connection

[sone]

Hey.

Im trying to sort out when one of my btGImpactMeshShapes collides with something and process it accordingly. I can do this quite fine right now using:

btCollisionObject* obA = static_cast<btCollisionObject*>(contactManifold->getBody0());
btCollisionObject* obB = static_cast<btCollisionObject*>(contactManifold->getBody1());
if(obA->getCollisionShape()->getName() == m_GImpactShape->getName() || obB->getCollisionShape()->getName() == m_GImpactShape->getName())

Problem is that this will only work for one btGImpactMeshShape since getName() returns ""GImpactMesh"" and nothing else, hard coded into btGImpactShape.h. I need to know which one of my btGImpactMeshShapes that is colliding in order to process that individual mesh properly. Ive overloaded btGImpactMeshShape just adding set/get debug_ID to enable tagging the shapes, but I still need to set the ID to something. My thought being ofc to set it to the same ID that bullet uses for its rigidbody. I CAN get this ID by doing:

btCollisionObject* obA = static_cast<btCollisionObject*>(contactManifold->getBody0());
btCollisionObject* obB = static_cast<btCollisionObject*>(contactManifold->getBody1());
btRigidBody* testA = (btRigidBody*)obA; //get the debugID of the rigidBody of the collision object.
btRigidBody* testB = (btRigidBody*)obA; //get the debugID of the rigidBody of the collision object.
testA->m_debugBodyId;
testB->m_debugBodyId;

However, in order to do that I need my btGImpactMeshShape to be a btCollisionObject being used by the btPersistentManifold, aka colliding with something. Im sure theres some way to access the rigidBody of the btGImpactshape in some other way, but I just cant seem to find how. What I would like to do is to access the rigidBody as soon as I creates my btGImpactMeshShape and set its debugBodyId accordingly. Any hints on how to do this? feeling kinda lost here atm

In Bullet arquitecture, collision classes are missing some Object Oriented features like object names, or identifiers, or introspection (class info).

You must provide a mechanism for storing that meta-information (like names or identifiers) in the btCollisionShape class. Just add an String attribute for that.

I suggest that Bullet should have a base class for all objects (Like btObject) which should has methods for assign-getting its name, identifiers and also class info (runtime type info).

But I think that added functionality could degrade the packed memory structure in Bullet objects, which is necessary for align their memory for SIMD operations.
