Question about Basic Tutorial 6 and mRoot

[sabyogre3d]

Hello!

It's the stupid-newbie-questions guy again .

I was working with Basic Tutorial 6 and there is something I don't understand, something that I hint it also has to do with how C++ deals with OOP.

We have this:

Code: Select all

Ogre::Root* mRoot;

which from my understanding, Root is a class and mRoot should be an object instantiated from Root but the explanation says

The first thing we'll do is add an Ogre::Root member to our class

So my totally newbie question is:

What is mRoot ? Is it a pointer object? Is it a data member type Root ?

Thanks and sorry again for such silly question but I really want to understand this stuff!

this is an instances names that in defaoult is NULL.

mRoot is not instanced without = operator.

for instancing need call:

Code: Select all

Ogre::Root::getSingleton(). (select function that you need);

for instancing need:

Code: Select all

Ogre::Root* mRoot = Ogre::Root::getSingletonPtr();

"Ptr" - is for "*" instances that selects throught "->"

and

Code: Select all

Ogre::Root mRoot = Ogre::Root::getSingleton();
