无法设置深度缓冲区？

// IMPORTANT: Call this function at the very beginning, before running your 1st scene
// Create a depth buffer of 24 bits
// These means that openGL z-order will be taken into account
[[CCDirector sharedDirector] setDepthBufferFormat:kDepthBuffer16];

允许在我的游戏中使用一些 3D 效果和动作。但是，由于某种原因，XCode 无法识别 setDepthBufferFormat 和 kDepthBuffer16。有什么想法吗？

In some cocos2d-iphone documentation, I was told to put this

// IMPORTANT: Call this function at the very beginning, before running your 1st scene
// Create a depth buffer of 24 bits
// These means that openGL z-order will be taken into account
[[CCDirector sharedDirector] setDepthBufferFormat:kDepthBuffer16];

To allow some 3D effects in my game with actions. However, for some reason, neither setDepthBufferFormat nor kDepthBuffer16 are recognized by XCode. Any ideas?

不幸的是，cocos2d 文档部分已过时。你提到的方法已经不存在了。相反，您必须修改应用程序委托方法 applicationDidFinishLaunching 中初始化 EAGLView 的行。有一个“viewWithFrame”变体，它采用 heightFormat 的额外参数：

// Create an EAGLView with a RGB8 color buffer, and a depth buffer of 24-bits
EAGLView* glView = [EAGLView viewWithFrame:[window bounds]
                               pixelFormat:kCCTexture2DPixelFormat_RGBA8888
                               depthFormat:GL_DEPTH_COMPONENT16_OES
                        preserveBackbuffer:NO
                                sharegroup:nil
                             multiSampling:NO
                           numberOfSamples:0];

The cocos2d documentation is partially out of date, unfortunately. The method you mentioned no longer exists. Instead, you will have to modify the line in the app delegate method applicationDidFinishLaunching that initializes the EAGLView. There's a "viewWithFrame" variant that takes the extra parameters of depthFormat:

// Create an EAGLView with a RGB8 color buffer, and a depth buffer of 24-bits
EAGLView* glView = [EAGLView viewWithFrame:[window bounds]
                               pixelFormat:kCCTexture2DPixelFormat_RGBA8888
                               depthFormat:GL_DEPTH_COMPONENT16_OES
                        preserveBackbuffer:NO
                                sharegroup:nil
                             multiSampling:NO
                           numberOfSamples:0];
