My goal here is to access the normal of a face of a mesh FROM a RigidBody that is colliding with that mesh/face.
So far I've been trying to use the RigidBody's ContactMonitor, which does have get_contact_local_normal ( int contact_idx ), although It's returning the normal of the GridMap itself (all the meshes/physicsbodies I'm trying to access are part of a GridMap). At least that's what I assume, because get_contact_collider_object ( int contact_idx ), returns the GridMap rather than the specific PhysicsBody within the GridMap, and after all, what I'm going for here is specificity.
