OnStep()

virtual void PhysicsStepListener::OnStep ( float  inDeltaTime, PhysicsSystem &  inPhysicsSystem  )

pure virtual

Called before every simulation step (received inCollisionSteps times for every PhysicsSystem::Update(...) call) This is called while all body and constraint mutexes are locked. You can read/write bodies and constraints but not add/remove them. Multiple listeners can be executed in parallel and it is the responsibility of the listener to avoid race conditions. The best way to do this is to have each step listener operate on a subset of the bodies and constraints and making sure that these bodies and constraints are not touched by any other step listener. Note that this function is not called if there aren't any active bodies or when the physics system is updated with 0 delta time.
