Here’s a small class I wrote for a quick and easy Ogre config and window. It’s got some inspiration from the some of the classes in the tutorial framework, but I really wanted to write something from scratch just to get a better understanding of set-up and initialization. I might be pulling in a custom config loader to remove the ugly config window and another frame listener with adapters (since I’m not sure I’m sold on OIS yet). Might throw this on my Github once it’s a little more fleshed out, but check it out for now. Pretty straightforward, and I really like the Ogre::FrameListener system now that I’ve figured it out.
#ifndef _SKELETON_APPLICATION_H #define _SKELETON_APPLICATION_H #include "Ogre.h" namespace Skeleton { class Application : public Ogre::FrameListener { private: Ogre::Root *_root; Ogre::RenderWindow *_window; Ogre::SceneManager *_sceneManager; Ogre::Camera *_cam; Ogre::Viewport *_viewport; public: Application() { // Load resources and config (borrowed from the tutorial framework) this->_root = new Ogre::Root("plugins_d.cfg", "resources_d.cfg"); this->_root->addFrameListener(this); } ~Application() { delete this->_root; } bool init() { // Get the settings from the config dialog if (!this->_root->showConfigDialog()) return false; // Auto create the window and store the pointer this->_window = this->_root->initialise(true, "Ogre Skeleton"); // Create the scene manager and camera this->_sceneManager = this->_root->createSceneManager(Ogre::ST_GENERIC); this->_cam = this->_sceneManager->createCamera("MainCamera"); // Set up the defaults for the camera this->_cam->setPosition(Ogre::Vector3(0, 0, 80)); this->_cam->lookAt(Ogre::Vector3(0, 0, -300)); this->_cam->setNearClipDistance(5); // Add the viewport to the window this->_viewport = this->_window->addViewport(this->_cam); this->_viewport->setBackgroundColour(Ogre::ColourValue(0, 0, 0)); // Black return true; } void run() { if (this->init()) { // Let Ogre handle the render loop this->_root->startRendering(); } } virtual bool frameRenderingQueued(const Ogre::FrameEvent& evt) { if (this->_window->isClosed()) { // Returning false in the frame listener callback triggers shutdown return false; } return true; } }; } #endif // _SKELETON_APPLICATION_H
