also i got a crash at deleting root
code is :

Code: Select all

			mutex->WaitOne();
			try

		                 }

			 {
				 mutex->ReleaseMutex();
				 Trace::WriteLine("OGRE :: ERROR ~ROOT()");
				 //throw(e);
				 return;

exception appears only sometimes....

Posted: **Mon Feb 14, 2005 6:37 pm**

You're using multithreaded code, and bugs that only occur sometimes are often a result of unpredictable behaviour caused by threading. Try it without threading, I bet it goes away.

What are you using threading for? Are you being careful about not calling into OGRE from 2 different threads?

Posted: **Tue Feb 15, 2005 4:52 pm**

about threading:

i don't use threads explicite , but .NET listeners model works like this (for example Timers, mouse listeners) you do not have any guarantee that events will be scheduled or queed , they can be raised to execute same lines at same time . that is why i use mutexes

i noticed also some problem in waterMesh.h/.cpp used in demo with water which looks like some triangle had one edge in NaN or 1^e20 position , still tracking it.... usually comes appears when i reload model

Code: Select all

mScene->removeEntity(ninjaEntity);
	ninjaEntity = mScene->createEntity("1", path );
	ninjaNode->attachObject(ninjaEntity);
