  1. POlaunching a coco2d OpenGL View from a viewcontroller
    text
    copied!<p>Normally, the coco2d OpenGL view is launched from the appdelegate. </p> <p>Method1: luanching from appdelegate </p> <pre><code>- (void) applicationDidFinishLaunching:(UIApplication*)application { // Init the window window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Try to use CADisplayLink director // if it fails (SDK &lt; 3.1) use the default director if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] ) [CCDirector setDirectorType:kCCDirectorTypeDefault]; CCDirector *director = [CCDirector sharedDirector]; // Init the View Controller viewController = [[RootViewController alloc] initWithNibName:nil bundle:nil]; viewController.wantsFullScreenLayout = YES; // // Create the EAGLView manually // 1. Create a RGB565 format. Alternative: RGBA8 // 2. depth format of 0 bit. Use 16 or 24 bit for 3d effects, like CCPageTurnTransition // // EAGLView *glView = [EAGLView viewWithFrame:[window bounds] pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8 depthFormat:0 // GL_DEPTH_COMPONENT16_OES ]; // attach the openglView to the director [director setOpenGLView:glView]; </code></pre> <p>but I need to able to launch the OpenGL view from a viewcontroller so, inside my viewcontroller's viewdidload function I did this</p> <p>method2: launch from viewcontroller - (void)viewDidLoad {</p> <pre><code> [super viewDidLoad]; self.view.frame = CGRectMake(0, 0, 320, 480); // Create an CCGLView with a RGB565 color buffer, and a depth buffer of 0-bits CCGLView *glView = [CCGLView viewWithFrame:CGRectMake(0,0,320,480) pixelFormat:kEAGLColorFormatRGB565 //kEAGLColorFormatRGBA8 depthFormat:0 //GL_DEPTH_COMPONENT24_OES preserveBackbuffer:NO sharegroup:nil multiSampling:NO numberOfSamples:0]; director_ = (CCDirectorIOS*) [CCDirector sharedDirector]; director_.wantsFullScreenLayout = YES; // Display FSP and SPF [director_ setDisplayStats:YES]; // set FPS at 60 [director_ setAnimationInterval:1.0/60]; // attach the openglView to the director [director_ setView:glView]; // for rotation and other messages [director_ setDelegate:self]; // 2D projection [director_ setProjection:kCCDirectorProjection2D]; // Run the intro Scene [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888]; // and add the scene to the stack. The director will run it when it automatically when the view is displayed. [director_ pushScene: [helloworld scene]]; </code></pre> <p>method2 is not working I don't see any scene, nothing shows up. so the question is how to make OpenGL View present from a viewcontroller?</p>
