I got missing triangles for CCPageTurnTransition at the left side of Ipad when i replace the scene.
Note that I have used :
[[CCDirector sharedDirector] setDepthBufferFormat:kDepthBuffer16];
and put at delegate method but my app crash and shown this error

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'A Director was alloced. setDirectorType must be the first call to Director

i also try to change cocos2d/CCPageTurn3DAction.m but still got the triangle. Currently im using cocos2d version 0.99.4-rc3.
```
// Stop z coord from dropping beneath underlying page in a transition
if( p.z<0.9f )
  p.z = 0.9f;
```

setDepthBufferFormat is deprecated in 0.99.4.

Here is the code I am using in 0.99.5 to set a 16-bit depth buffer:

window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
    [CCDirector setDirectorType:kCCDirectorTypeNSTimer];
CCDirector *director = [CCDirector sharedDirector];
[director setDeviceOrientation:kCCDeviceOrientationPortrait];
[director setDisplayFPS:YES];
[director setAnimationInterval:1.0/60];
EAGLView *glView = [EAGLView viewWithFrame:[window bounds]
                                 pixelFormat:kEAGLColorFormatRGB565
                                 depthFormat:GL_DEPTH_COMPONENT16_OES
                          preserveBackbuffer:NO];
[director setOpenGLView:glView];
[window addSubview:glView];
[window makeKeyAndVisible];

I copied and modified code from the CC_DIRECTOR_INIT() function.

Thanks neophit for the help...
and wanna to ask... should i copy all of this of code in order to set Depth Buffer?
Can i know why this code wont work?

[[CCDirector sharedDirector] setDepthBufferFormat:kDepthBuffer16];

after i copy you code and put into appDelegate after CC_DIRECTOR_INIT();
it shown error
```
Program received signal:  “SIGABRT”.
Assertion failed: (cls), function getName, file /SourceCache/objc4_Sim/objc4-427.1.1/runtime/objc-runtime-new.m, line 3939.
```
The error was mark at this code
```
if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )
		[CCDirector setDirectorType:kCCDirectorTypeNSTimer];
```

CC_DIRECTOR_INIT() performs the following tasks on your behalf:

1. Initializes an EAGLView with 0-bit depth format, and RGB565 render buffer
2. EAGLView multiple touches: disabled
3. creates a UIWindow, and assign it to the "window" var (it must already be declared)
4. Parents EAGLView to the newly created window
5. Creates Display Link Director
5a. If it fails, it will use an NSTimer director
6. It will try to run at 60 FPS
7. Display FPS: NO
8. Device orientation: Portrait
9. Connects the director to the EAGLView

Since setDepthBufferFormat has been deprecated the API is no longer supported. The depth buffer is now set for you inside the CC_DIRECTOR_INIT() function. To set a different depth buffer, you could modify the CC_DIRECTOR_INIT() function or copy and modify the code like I showed in my last post. If you choose the latter, you need to comment out the call to CC_DIRECTOR_INIT() and paste the code below it.

If anyone knows an easier way to just set the depth buffer, please speak up.

So means i only set to this in the CCDirector.m

- (id) init
{
	CCLOG(@"cocos2d: %@", cocos2dVersion() );

	if( (self=[super init]) ) {

		CCLOG(@"cocos2d: Using Director Type:%@", [self class]);

		// default values
		pixelFormat_ = kCCPixelFormatDefault;
		//depthBufferFormat_ = 0;
                   depthBufferFormat_ = kDepthBuffer16;

		// scenes
		runningScene_ = nil;
		nextScene_ = nil;

		oldAnimationInterval = animationInterval = 1.0 / kDefaultFPS;
		scenesStack_ = [[NSMutableArray alloc] initWithCapacity:10];

		// landscape
		deviceOrientation_ = CCDeviceOrientationPortrait;

		// FPS
		displayFPS = NO;
		frames = 0;

		// paused ?
		isPaused_ = NO;

		contentScaleFactor_ = 1;
		screenSize_ = surfaceSize_ = CGSizeZero;
		isHighResDevice_ = NO;
	}

	return self;
}

after i change into this i still can see the page flip transition still got missing triangle on simulator. if there any missing code that should i insert?

Are you seeing the triangles on the device? I also see artifacts in the simulator, but they do not appear on my device.

I'm using cocos2d v0.99.4, the depthFormat settings is in ccMacros.h in the CC_DIRECTOR_INIT() macro

thanks alot abitofcode and neophit spending your time to solve my problem. yeah the code that neophit talk about i can see in CCMacros.h

#define CC_DIRECTOR_INIT()																		\
do	{																							\
	window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];					\
	if( ! [CCDirector setDirectorType:kCCDirectorTypeDisplayLink] )								\
		[CCDirector setDirectorType:kCCDirectorTypeNSTimer];									\
	CCDirector *__director = [CCDirector sharedDirector];										\
	[__director setDeviceOrientation:kCCDeviceOrientationPortrait];								\
	[__director setDisplayFPS:NO];																\
	[__director setAnimationInterval:1.0/60];													\
	EAGLView *__glView = [EAGLView viewWithFrame:[window bounds]								\
									pixelFormat:kEAGLColorFormatRGB565							\
									depthFormat:0 			\
							 preserveBackbuffer:NO];											\
	[__director setOpenGLView:__glView];														\
	[window addSubview:__glView];																\
	[window makeKeyAndVisible];																	\
} while(0)

i just changed depthFormat:0 to depthFormat:GL_DEPTH_COMPONENT24_OES and it works.

But if i change to GL_DEPTH_COMPONENT16_OES it also works but the frame rate drops alot. i testing on simulator... will be tested on device tomorrow. :)

Hi All! Can anyone post some example source code to show how the CCPageTurnTransition function works on a real apps? Thanks!

There is sample code in the tests directory when you down load cocos2d. Use Shift + Command + F to search across the whole project and you'll find it.

I downloaded and installed cocos2d in xcode and the only sample I have is the "Cocos2DSimpleGame". I searched thru the directory and couldn't find any "tests directory" that you mentioned. Please help! Thanks!

Open the project file in the cocos2d directory rather than creating a cocos2d application from the template, the templates will not add the test code to a project.
