GlView 导致 OpenGL 错误

问题描述

我是 cocos2d 的新手.我正在使用 cocos2d(3.0 Beta) 平台的 uiview 进行游戏.我在自定义视图控制器中设置了一个 GLView.下面是我的代码.

I am new in cocos2d.I am making a gaming with uiview with cocos2d(3.0 Beta) platform.I set a GLView in custom viewcontroller. Below is my code.

 - (void)setupCocos2D {

        CCGLView *glView = [CCGLView viewWithFrame:self.view.bounds pixelFormat:kEAGLColorFormatRGB565 depthFormat:0];**

       glView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

        [self.view insertSubview:glView atIndex:0];

       [[CCDirector sharedDirector] setView:glView];**

    }

它工作正常.但是当我们戴上对象时，然后给我跟随内存磨损.

It's working fine.But when we put on object then give me Following Memory worning.

OpenGL error 0x0506 in -[CCSprite draw] 544
OpenGL error 0x0502 in -[CCGLView swapBuffers] 287**

我认为当我们调用 ([[CCDirector sharedDirector] setView:glView]) setView 方法时，它不是找到 CCDirector 方法而是 UIView 方法.我无法访问 CCDirector 方法.我也使用相同的方法无法调用 AppDelegate 类.

I think when we call ([[CCDirector sharedDirector] setView:glView]) setView method it's not find CCDirector method but UIView method.I can't Access the CCDirector method.Same Method I also can't call in AppDelegate class.

- (void)applicationWillTerminate:(UIApplication *)application {

    CCDirector *director = [CCDirector sharedDirector];

  //openGLView is now (setView in Latest version).It's Can't Access here.**

  [[director openGLView] removeFromSuperview];
    [director end];
}

推荐答案

你在 setupCocos2D 中使用下面的代码

You use below Code in setupCocos2D

 - (void)setupCocos2D
 {
    [[CCDirector sharedDirector] end];

    UIWindow *window_ = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];


    [window_ setBackgroundColor:[UIColor whiteColor]];


    CCGLView *glView = [CCGLView viewWithFrame:[window_ bounds]
                                   pixelFormat:kEAGLColorFormatRGB565
                                   depthFormat:0
                            preserveBackbuffer:NO
                                    sharegroup:nil
                                 multiSampling:NO
                               numberOfSamples:0];

    director_ = (CCDirectorIOS*) [CCDirector sharedDirector];

    director_.wantsFullScreenLayout = YES;

    // Display FSP and SPF
    [director_ setDisplayStats:NO];

    // set FPS at 60
    [director_ setAnimationInterval:1.0/60];

    // attach the openglView to the director
    [director_ setView:glView];

    // 2D projection
    [director_ setProjection:kCCDirectorProjection2D];



    //  [director setProjection:kCCDirectorProjection3D];

    // Enables High Res mode (Retina Display) on iPhone 4 and maintains low res on all other devices
    if( ! [director_ enableRetinaDisplay:YES] )
        CCLOG(@"Retina Display Not supported");

    // Default texture format for PNG/BMP/TIFF/JPEG/GIF images
    // It can be RGBA8888, RGBA4444, RGB5_A1, RGB565
    // You can change this setting at any time.
    [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888];

    CCFileUtils *sharedFileUtils = [CCFileUtils sharedFileUtils];
    [sharedFileUtils setEnableFallbackSuffixes:NO];             // Default: NO. No fallback suffixes are going to be used
    [sharedFileUtils setiPhoneRetinaDisplaySuffix:@"-hd"];      // Default on iPhone RetinaDisplay is "-hd"
    [sharedFileUtils setiPadSuffix:@"-ipad"];                   // Default on iPad is "ipad"
    [sharedFileUtils setiPadRetinaDisplaySuffix:@"-ipadhd"];    // Default on iPad RetinaDisplay is "-ipadhd"

    // Assume that PVR images have premultiplied alpha
    [CCTexture2D PVRImagesHavePremultipliedAlpha:YES];


 }
