Hello, I'm trying to create a game state machine using for menu intro BetaGUI(great but you ll laugh of me) and using a nxOgre_World for playsate.
I can launch application and go on menu, launch playstate and come back to menu, but when I re-launch playstate I obtain this error:



10:08:30: An exception has been thrown!



-----------------------------------

Details:

-----------------------------------

Error #: 6

Function: ResourceManager::add

Description: Resource with the name NxOgre.ErrorCube already exists.. 

File: \OgreDev\Dagon\OgreMain\src\OgreResourceManager.cpp

Line: 89

Stack unwinding: <<beginning of stack>>

When I quit my playstate I do this:



void PlayState::exit()

{



    delete mWorld;



	if(mVehicle)

        delete mVehicle;



	mSceneMgr->clearScene();

	mSceneMgr->destroyAllCameras();

	mRoot->getAutoCreatedWindow()->removeAllViewports();

	mSceneMgr->destroyAllBillboardSets();

	mSceneMgr->destroyAllParticleSystems();

	mSceneMgr->destroyAllMovableObjects();

	mSceneMgr->destroyAllEntities();

	mSceneMgr->destroyAllLights();

	mSceneMgr->destroyAllManualObjects();

	mSceneMgr->destroyAllStaticGeometry();

	mSceneMgr->destroyAllAnimations();

	mSceneMgr->destroyAllAnimationStates();



	std::cout << "PlayState exit\n";

}

For each state I create a new SceneManager and for playstate I create a new world.

What is wrong? thx

You shouldn't delete world like that, it's a singleton.

world::reset is what you need.

Yes, you are allright. But I want to delete completly world and return to my first game state (menu without world). Then I will use world::release function that destroy all scene, remove framelistener and destroy all scene attached.
But I obtain same error.
Must I destroy resources or something like this?

thanks for your help. :roll:

Hum, I am so stupid sometimes. I use like you say worldreset and it s work fine. I use static game state like in exemple in Ogre wiki and world will not be deleted as I try.

I consider this solved, but memory leaks will appears or not?

thx
