Using the code from before we are now going to use our own rendering loop.
Our application needs to know if it should keep running or not; add a
Booleanas a private member of the application to remember the state:bool _keepRunning;
Remove the
startRenderingfunction call in thestartupfunction.Add a new function called
renderOneFrame, which calls therenderOneFramefunction of therootinstance and saves the return value in the_keepRunningmember variable. Before this call, add a function to process all window events:void renderOneFrame() { Ogre::WindowEventUtilities::messagePump(); _keepRunning = _root->renderOneFrame(); }Add a getter for the
_keepRunningmember variable:bool keepRunning() { return _keepRunning; }Add a
whileloop to the main function, which keeps running as long as thekeepRunningfunction returnstrue. In the body of the loop, call therenderOneFramefunction of the application.while(app.keepRunning()) { app.renderOneFrame...
