Questions on memory management convention

[wqking]

I have some questions on how Irrlicht management memory. I didn't find the document about that.

1, We should never use C++ "delete", right?

2, All objects are inherited from IReferenceCounted, that's why we don't "delete", right?

3, Is there any name convention? Is any function name start with "createXXX" returning an object and transfer the ownership? That's to say, for any object returned by createXXX, we must "drop" it?

4, From this page,
http://spottedsun.com/irrlicht-drop-remove-and-delete/
For ISceneNode, we should use "remove" instead of "drop", right?

Thanks in advance.

Yes, it's pretty much just as you said. See the documentation for IReferenceCounted: http://irrlicht.sourceforge.net/docu/cl ... unted.html

And about ISceneNode - the remove is really about removing it from the scenemanager - it just deletes as well if no one else has a reference anymore. Personally I think ISceneNode::remove should probably have been ISceneManager::removeNode instead to make this more clear - at least you should think of it like that.
