Networked Physics with PhysX

I don’t know why but I’m getting this error:


Exception thrown at 0x00007FFFE85C72E7 (PhysX3PROFILE_x64.dll) in UE4Editor.exe: 0xC0000005: Access violation reading location 0x0000000000000000.

At this line: PScene->getActors(PxActorTypeFlag::eRIGID_DYNAMIC, DynamicActors.GetData(), DynamicActorsNum);

Here I’m taking only the Dynamic actors for a test.
Did you do in this way?



	PxScene* PScene = GetWorld()->GetPhysicsScene()->GetPhysXScene(PST_Sync);

	const PxU32 DynamicActorsNum = PScene->getNbActors(PxActorTypeFlag::eRIGID_DYNAMIC);
	TArray<PxActor*> DynamicActors;
	DynamicActors.AddUninitialized(DynamicActorsNum);
	PScene->getActors(PxActorTypeFlag::eRIGID_DYNAMIC, DynamicActors.GetData(), DynamicActorsNum);
	
        FPhysScene* PS = new FPhysScene();
	PxScene* RRPScene = PS->GetPhysXScene(PST_Sync);

	PScene->removeActors(DynamicActors.GetData(), DynamicActorsNum);
	RRPScene->addActors(DynamicActors.GetData(), DynamicActorsNum);

	for (int32 a = 0; a < 2; ++a) {
		RRPScene->simulate(1.f / 60.f);
		RRPScene->fetchResults(true);
	}
	RRPScene->removeActors(DynamicActors.GetData(), DynamicActorsNum);
	PScene->addActors(DynamicActors.GetData(), DynamicActorsNum);

	delete PS;
	PS = nullptr;
