why btSoftRigidCollisionAlgorithm does not need any manifolds

Post by helloworrrrrld »

Hi everyone:
I am using Bullet v2.88 as my rendering engine's physics engine.
I have added one dynamic rigid body and one soft body to the physics world. And I want to get the collision pair by using the function
"world->getDispatcher()->getManifoldByIndexInternal(i);"
but I find that the soft body can not be found by this interface.
I find the reason that the class btSoftRigidCollisionAlgorithm has no btPersistentManifold. Can anyone tell me the reason?
So how I can get the collision pairs that contains a soft body?

Thanks.
