I was hoping someone could help me figure out why my btPairCachingGhostObject "holds" onto a pair until it's well outside its range

I tried cleaning the proxy after each time it's moved, but that didn't seem to help

also I normally set forceUpdateAABB to false when I create the physics world, but I tried commenting that out and it didn't help

any ideas would be appreciated!

this is how I'm detecting buildings inside the ghost object:

(FYI "GlobalID" is like a GUID for each object/building in the simulation)

Code: Select all

```
bool TranceEngine::getAllOverlappingBuildings(btPairCachingGhostObject* myGhostObject, vector<teEntityDatabaseModule::entityIndex>& potentialBuildings)
{
bool foundABuilding = false;
btManifoldArray manifoldArray;
btBroadphasePairArray& pairArray = myGhostObject->getOverlappingPairCache()->getOverlappingPairArray();
int numPairs = pairArray.size();
for (int k = 0; k < numPairs; ++k)
{
manifoldArray.clear();
const btBroadphasePair& pair = pairArray[k];
btBroadphasePair* collisionPair = physicsModule->dynamicsWorld->getPairCache()->findPair(pair.m_pProxy0, pair.m_pProxy1);
if (!collisionPair) continue;
if (collisionPair->m_algorithm)
collisionPair->m_algorithm->getAllContactManifolds(manifoldArray);
for (int j = 0; j < manifoldArray.size(); j++)
{
btPersistentManifold* manifold = manifoldArray[j];
for (int p = 0; p < manifold->getNumContacts(); ++p)
{
const btManifoldPoint& pt = manifold->getContactPoint(p);
if (pt.getDistance() < 0.f)
{
// Object is inside ghost's shape at this manifold point
// process shape overlap here
int managerID1 = manifold->getBody0()->getUserIndex();
int globalID1 = manifold->getBody0()->getUserIndex2();
int globalID2 = manifold->getBody1()->getUserIndex2();
int managerID2 = manifold->getBody1()->getUserIndex();
if (globalID1 > 0) //found a valid GlobalID
{
if (managerModule->managers[managerID1]->isBuilding)
{
potentialBuildings.emplace_back(teEntityDatabaseModule::entityIndex({ managerID1,globalID1 }));
foundABuilding = true;
}
}
else if (globalID2 > 0) //found a valid GlobalID
{
if (managerModule->managers[managerID2]->isBuilding)
{
potentialBuildings.emplace_back(teEntityDatabaseModule::entityIndex({ managerID2,globalID2 }));
foundABuilding = true;
}
}
/*
else
{
//std::cout << "invalid Target found: myGhostObject: " << myGhostObject << " body0: " << test3 << ":" << test4 << " body1: " << test1 << ":" << test2 << "\n";
}*/
}/*
else
{
// Object is in ghost's aabb but not inside its shape at this manifold point
// process aabb overlap here
}*/
}
}
}
return foundABuilding; //didn't find shit
}
```
