Ogre 3D 1.7

Time for action — modifying the number of pixels with user input

We are going to use the knowledge about user input and frame listeners that we have seen in Chapter 3,Camera, Light, and Shadow

1. Our application needs FrameListener. Add a new private variable to store the pointer to the application:

   Ogre::FrameListener* FrameListener;
   

2. In the same way, FrameListener should also be inited with NULL:

   Example79()
   {
   FrameListener = NULL;
   compListener = NULL;
   }
   

3. And it should be destroyed in the same way:

   ~Example79()
   {
   if(compListener)
   {
   delete compListener;
   }
   if(FrameListener)
   {
   delete FrameListener;
   }
   }
   

4. Lets add it and then implement it. The rest of the application class doesn't change:

   void createFrameListener() { FrameListener = new Example79FrameListener(mWindow,compListener); ...
