I have the following problem - im trying to set up multi-threaded calculations in BP, however, not all seems to be going as it should. Here's the init code:
Code: Select all
static CustomTaskScheduler TaskScheduler(TEXT("bullet physics task scheduler"), PhysicsThreadCount); TaskScheduler.setNumThreads(PhysicsThreadCount); btSetTaskScheduler(&TaskScheduler); CollisionConfiguration = new btDefaultCollisionConfiguration(); Dispatcher = new btCollisionDispatcherMt(CollisionConfiguration); OverlappingPairCache = new btDbvtBroadphase(); SolverPool = new btConstraintSolverPoolMt(PhysicsThreadCount); DynamicsWorld = new btDiscreteDynamicsWorldMt(Dispatcher, OverlappingPairCache, SolverPool, nullptr, CollisionConfiguration);
When I launch the simulation, however, all the task threads in the scheduler i wrote. Breakpoints in parallelFor() and parallelSum() are not being hit at all. In the thread list i see the threads from the CustomTaskScheduler, but no other additional Bullet-related threads. So all in all, it seems like despite everything, Bullet still operated on a single thread. Is there something im missing in my initialization?
EDIT: Previously i forgot to use Mt version of dispatcher. After the fix, however, it still doesnt seem to use other threads.
