起先我发现切割图片的贴图错误了,但是找不到问题在哪. 于是我自己来回测试,发现每隔一个CCClippingNode创建一个空的CCClippingNode就不会出现这个问题,于是我发现了是openGL缓存的问题,

另外stencil深度需要开启,cpp项目在AppController.mm中,默认新版模板是开启的,老版模板是关闭的,所以我发现我的demo能运行,而老游戏不支持:

改为

EAGLView *__glView = [EAGLView viewWithFrame: [window bounds]
                                     pixelFormat: kEAGLColorFormatRGB565
                                     depthFormat: GL_DEPTH24_STENCIL8_OES
                              preserveBackbuffer: NO
                                      sharegroup: nil
                                   multiSampling: NO
                                 numberOfSamples:0 ];

1. glStencilFunc(GL_NEVER,mask_layer,mask_layer);
2. glClearStencil(!m_bInverted?0:~0);
3. glStencilOp(!m_bInverted?GL_ZERO:GL_REPLACE,GL_KEEP,GL_KEEP);
5. //drawafullscreensolidrectangletoclearthestencilbuffer
6. //ccDrawSolidRect(CCPointZero,ccpFromSize([[CCDirectorsharedDirector]winSize]),ccc4f(1,1,1));
7. ccDrawSolidRect(CCPointZero,ccpFromSize(CCDirector::sharedDirector()->getWinSize()),1));
8. glClear(GL_STENCIL_BUFFER_BIT);

标红的地方是新添加的,效果刚刚
