[Question] how dose dtPathQueue work with only one dtNavMeshQuery?

[Shuai]

Hello. I'm trying to figure out how dtPathQueue works and find this in the dtPathQueue::update() function.

recastnavigation/DetourCrowd/Source/DetourPathQueue.cpp

Lines 111 to 126 in d0b2ed8

 // Handle query start. 
 if (q.status == 0) 
 { 
 	q.status = m_navquery->initSlicedFindPath(q.startRef, q.endRef, q.startPos, q.endPos, q.filter); 
 }		 
 // Handle query in progress. 
 if (dtStatusInProgress(q.status)) 
 { 
 	int iters = 0; 
 	q.status = m_navquery->updateSlicedFindPath(iterCount, &iters); 
 	iterCount -= iters; 
 } 
 if (dtStatusSucceed(q.status)) 
 { 
 	q.status = m_navquery->finalizeSlicedFindPath(q.path, &q.npath, m_maxPathSize); 
 } 

if there are more than one dtPathQuery InProgress, how to determine which should be updated in line 120 as all dtPathQuery share the same m_navquery?

dosen't every dtPathQuery in the queue need a corresponding dtNavmeshQuery instead of sharing the same one?
