Next, we need to add an event handler for when the user selects the new menu item. Right-click on the RobotMesh menu item, and choose Add Event Handler. 13. In the Event Handler Wizard that appears, set the Function handler name to OnLoadRobot, select CPluginManagerView from the Class List, and then press Add and Edit. loadPlugin("Robot3"); } When we call loadPlugin(), Ogre will load our Robot plugin and call dllStartPlugin(), after which, Ogre will call initialize(), and our robot will appear in our application window.

In the new header file, create a new class called Robot3Plugin that derives from Ogre::Plugin. h" class Robot3Plugin : public Ogre::Plugin{ public: Ogre::String m_Name; Robot3Plugin(){ m_Name = "Robot"; } }; 35 Delving Deep into Application Design 7. renderOneFrame(); } void shutdown(){} void uninstall(){} The getName() function simply returns the unique name of our plugin. Every other method, except for initialise(), we leave empty. In the initialise() method, we load our robot mesh, create the robot entity, and attach it to a scene node.

H files from the Cookbook sample MFC application to our new project folder, and add them to the project. h, and add a new member variable for our CEngine instance, and a declaration of the InitEngine() function that we'll be adding. public: CEngine* m_Engine; void InitEngine(void); 12. cpp, modify the COgreInMfcApp constructor to give our new member variable a default value. COgreInMfcApp::COgreInMfcApp() : m_Engine(NULL) 13. Then, add our familiar InitEngine() function. void COgreInMfcApp::InitEngine(void){ m_Engine = new CEngine(); } 14.
