CCEGLView* view = CCEGLView::sharedOpenGLView(); view->setDesignResolutionSize(640, 960, kResolutionNoBorder);
CCEGLView* view = CCEGLView::sharedOpenGLView(); view->setDesignResolutionSize(1024, 768, kResolutionExactFit);This code sets the game window to a resolution of 1024x768 pixels, with the content scaled to fit exactly within the window. This is useful for games that require precise placement of graphics and UI elements. The CCEGLView class is part of the cocos2d namespace, and is included in the Cocos2d-x package library.
