Class member overloading..?

[dwfait]

Hi..I'm wondering if you can do something like this:

Code: Select all

class a
{
     public:
          ISceneNode* Node;
}


class b : public a
{
      public:
            ICameraSceneNode* Node;
}

I have code like that to similar effect in my project, and it compiles fine, but whenever a function is called that addressed the ICameraSceneNode Node, the program "encounters an unexpected error and has to close".

If it's not possible, can anyone give any suggestions to workarounds?

You could do the following:

Code: Select all

class a
{
    public:
        a(ISceneNode* Node)
        {
            m_Node = Node;
        }
        ISceneNode* m_Node;
};

class b : public a
{
    public:
        b(ICameraSceneNode* cam) : a(cam)
        {
            m_cam = cam;
        }
        ICameraSceneNode* m_cam;
};

That way u can use the scenenode like a scenenode out of the base class and the camera from the otherone.

The error is due to the elements being pointers which you have to set to pointing to existing objects. Otherwise each access will crash your app.
