Overlaymanager pointer?

LordMyth · Post by **LordMyth** » Mon Feb 14, 2005 7:42 pm

Ogre::OverlayManager* OverlayManager = Ogre::OverlayManager::getSingleton();
When doing this I get an error:
MythApp.h:144: error: cannot convert `Ogre::OverlayManager' to ` Ogre::OverlayManager*' in initialization

Is this fixed in the CVS?

use getSingletonPtr() or use the & operator on the result of getSingleton()

Actually it never was broken. use getSingletonPtr().

Oh, OK thanks! What does the getSingleton() function do?

It returns a reference instead.

It return a reference to the class instead of a pointer.

Ahh! yes of course... I'm stupid these days

Hmm.. Wonder if it would look better if I accessed things with App::SceneManager.blabla() instead of App::SceneManager->blabla();

getSingleton() has an advantage compared to getSingletonPtr(), imho: You get an expressive assertion failed excepetion, when it isn't initialized. getSingletonPtr() will only give you a null pointer.

Ow! Cool! I'll change everything to references then...
