Ogre2.1 store weak_ptr in setUserAny

[Lax]

Hello all,

is it possible to store in setUserAny a weak_ptr?

It seems odd, but I have the following problem:
I use:

Code: Select all

this->entity->getUserObjectBindings().setUserAny(boost::shared_ptr<GameObject>(gameObjectPtr));

To store a shared_ptr
and later when e.g. selecting a game object, I get it this way:

Code: Select all

gameObjectPtr = Ogre::any_cast<boost::shared_ptr<GameObject>>((targetEntity->getUserObjectBindings().getUserAny()));

But now the mess starts. When I quit my application, I get pointer corruption, because the Ogre Entity maintains my game object, because it maintains the reference count.
So I would like to store a weak_ptr of a game object instead.

I tried to, but I get tons of errors.
I did the following:

Code: Select all

this->entity->getUserObjectBindings().setUserAny(Ogre::Any(boost::weak_ptr<GameObject>(gameObjectPtr)));

and later:

Code: Select all

const Ogre::Any& any = (*itr)->getUserObjectBindings().getUserAny();
boost::weak_ptr<GameObject> weakPtr = Ogre::any_cast<boost::weak_ptr<GameObject>>(any);
GameObjectPtr gameObjectPtr = NOWA::makeStrongPtr(weakPtr);

Or maybe its a bad idea to store a shared_ptr in user any. The problem is, when I select a game object, I need the shared_ptr<GameObject> to feed for other functions...
