Detailed Description

btCollisionObject can be used to manage collision detection objects.

btCollisionObject maintains all information that is needed for a collision detection: Shape, Transform and AABB proxy. They can be added to the btCollisionWorld.

◆ m_internalType

int btCollisionObject::m_internalType
protected

m_internalType is reserved to distinguish Bullet's btCollisionObject, btRigidBody, btSoftBody, btGhostObject etc.

do not assign your own m_internalType unless you write a new dynamics object class.
