hi, we’re making a mobile game use astarpathfindproject with gridgraph and rvo simulator on ios/android. both pathfinding request and rvo simulator use multiple thread. there’s a issue my teamates found on ios that is kill the game manuelly when playing. the tester found if in battle which use pathfinding request and rvo simulator, the ios will report a crash but if the battle end(no more pathfinging request and rvo simulator) the game quit normally. it should be caused by multithreading. while in ios you shouldn’t write exit code in onapplicationquit() but should use onapplicationpause().(android and unity editor works normally)
so any hint or advice to do with this issue?
thanks.
Hi
Do you have some error logs or anything I could use?
I’m not quite sure what the pathfinding threads would be doing wrong.
usually, the thread works well. the only issue is when you kill the game when use ios home button to suspend curent game, and then kill the process, it will report a exception.
after the error dialog show, i check the ios crash.log,it looks like this

i’m trying to add function on xxxxBehavior :: OnapplicationQuit. Can you provide a safe method to kill all the pathfindg request and rvo simulator’s thread?
Hmm, you can always try to load a new empty scene before quitting the game. Maybe that will work around the issue?
