iphone - 我想用 uikit( Nib 或 Storyboard)设置 cocos3d，但我收到错误

Question

当我从我的 View Controller 调用动画时，我试图在我的 View Controller 上调用 cocos3d 动画然后我收到错误。

"cocos2d: 使用 Director Type:CCDirectorTimer[错误] cocos23Layer 需要 Controller 来渲染 3D 场景。2013-08-29 11:54:56.419 MaskedCal[3854:c07] * -[cocos23Layer initWithController:],/Users/34in/Desktop/cocos23/cocos23/cocos23/cocos3d/cocos3d 断言失败/Scenes/CC3Layer.m:74 "

这是我的 View Controller ，我想在其中调用我的 cocos3d 动画

- (void)setupCocos2D {
    EAGLView *glView = [EAGLView viewWithFrame:self.view.bounds
                                 pixelFormat:kEAGLColorFormatRGB565   // kEAGLColorFormatRGBA8
                                 depthFormat:0                        // GL_DEPTH_COMPONENT16_OES
                      ];

    [[CCDirector sharedDirector] setOpenGLView:glView];

    // Create the customized CC3Layer that supports 3D rendering.
    CC3Layer* cc3Layer = [cocos23Layer node];

   // cc3Layer = [cocos23Layer layerWithColor: ccc4(100, 120, 220, 255)];
    //[cc3Layer scheduleUpdate];

//   self.view = glView;
//    [CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888];

    cc3Layer.cc3Scene = [cocos23Scene scene];


    CC3ControllableLayer* mainLayer = cc3Layer;
//    
//    CCScene *scene = [CCScene node];
//    [scene addChild: mainLayer];
//    [[CCDirector sharedDirector] runWithScene: scene];

    mainLayer.contentSize = CGSizeMake(2048, 1320);
    [CCDirector sharedDirector].animationInterval = (1.0f / 60.0f);
    [CCDirector sharedDirector].displayStats = YES;
    [[CCDirector sharedDirector] enableRetinaDisplay: YES];

    [[CCDirector sharedDirector] runWithScene:mainLayer];

}

*这是我的 cocos23scene 动画发生的地方 *

-(无效)初始化场景{

// Create the camera, place it back a bit, and add it to the scene
CC3Camera* cam = [CC3Camera nodeWithName: @"Camera"];
cam.location = cc3v( 0.0, 0.0, 6.0 );
[self addChild: cam];

// Create a light, place it back and to the left at a specific
// position (not just directional lighting), and add it to the scene
CC3Light* lamp = [CC3Light nodeWithName: @"Lamp"];
lamp.location = cc3v( -2.0, 0.0, 0.0 );
lamp.isDirectionalOnly = NO;
[cam addChild: lamp];

// This is the simplest way to load a POD resource file and add the
// nodes to the CC3Scene, if no customized resource subclass is needed.
[self addContentFromPODFile: @"hello-world.pod"];

// Create OpenGL buffers for the vertex arrays to keep things fast and efficient, and to
// save memory, release the vertex content in main memory because it is now redundant.
[self createGLBuffers];
[self releaseRedundantContent];

// Select an appropriate shader program for each mesh node in this scene now. If this step
// is omitted, a shader program will be selected for each mesh node the first time that mesh
// node is drawn. Doing it now adds some additional time up front, but avoids potential pauses
// as each shader program is loaded as needed the first time it is needed during drawing.
[self selectShaderPrograms];

// With complex scenes, the drawing of objects that are not within view of the camera will
// consume GPU resources unnecessarily, and potentially degrading app performance. We can
// avoid drawing objects that are not within view of the camera by assigning a bounding
// volume to each mesh node. Once assigned, the bounding volume is automatically checked
// to see if it intersects the camera's frustum before the mesh node is drawn. If the node's
// bounding volume intersects the camera frustum, the node will be drawn. If the bounding
// volume does not intersect the camera's frustum, the node will not be visible to the camera,
// and the node will not be drawn. Bounding volumes can also be used for collision detection
// between nodes. You can create bounding volumes automatically for most rigid (non-skinned)
// objects by using the createBoundingVolumes on a node. This will create bounding volumes
// for all decendant rigid mesh nodes of that node. Invoking the method on your scene will
// create bounding volumes for all rigid mesh nodes in the scene. Bounding volumes are not
// automatically created for skinned meshes that modify vertices using bones. Because the
// vertices can be moved arbitrarily by the bones, you must create and assign bounding
// volumes to skinned mesh nodes yourself, by determining the extent of the bounding
// volume you need, and creating a bounding volume that matches it. Finally, checking
// bounding volumes involves a small computation cost. For objects that you know will be
// in front of the camera at all times, you can skip creating a bounding volume for that
// node, letting it be drawn on each frame.
[self createBoundingVolumes];


// ------------------------------------------

// That's it! The scene is now constructed and is good to go.

// To help you find your scene content once it is loaded, the onOpen method below contains
// code to automatically move the camera so that it frames the scene. You can remove that
// code once you know where you want to place your camera.

// If you encounter problems displaying your models, you can uncomment one or more of the
// following lines to help you troubleshoot. You can also use these features on a single node,
// or a structure of nodes. See the CC3Node notes for more explanation of these properties.
// Also, the onOpen method below contains additional troubleshooting code you can comment
// out to move the camera so that it will display the entire scene automatically.

// Displays short descriptive text for each node (including class, node name & tag).
// The text is displayed centered on the pivot point (origin) of the node.
//  self.shouldDrawAllDescriptors = YES;

// Displays bounding boxes around those nodes with local content (eg- meshes).
//  self.shouldDrawAllLocalContentWireframeBoxes = YES;

// Displays bounding boxes around all nodes. The bounding box for each node
// will encompass its child nodes.
//  self.shouldDrawAllWireframeBoxes = YES;

// If you encounter issues creating and adding nodes, or loading models from
// files, the following line is used to log the full structure of the scene.
LogInfo(@"The structure of this scene is: %@", [self structureDescription]);

// And to add some dynamism, we'll animate the 'hello, world' message
// using a couple of actions...

是的，我已经让它工作了，只需从你的 View Controller 中调用它

CCTexture2D.defaultAlphaPixelFormat = kCCTexture2DPixelFormat_RGBA8888; //** COCOS3D 设置代码开始... **

// Create the customized CC3Layer that supports 3D rendering.





if( ! [CCDirector setDirectorType: kCCDirectorTypeDisplayLink] )
    [CCDirector setDirectorType: kCCDirectorTypeDefault];

// Create the view controller for the 3D view.
_viewController = [CC3DeviceCameraOverlayUIViewController new];
_viewController.supportedInterfaceOrientations = UIInterfaceOrientationMaskAll;
_viewController.viewShouldUseStencilBuffer = NO;        // Set to YES if using shadow volumes
_viewController.viewPixelSamples = 1;                   // Set to 4 for antialiasing multisampling










// Create the CCDirector, set the frame rate, and attach the view.
CCDirector *director = CCDirector.sharedDirector;
director.runLoopCommon = YES;       // Improves display link integration with UIKit
director.animationInterval =(1.0f / kAnimationFrameRate);
director.displayFPS = YES;
director.openGLView = _viewController.view;

// Enables High Res mode on Retina Displays and maintains low res on all other devices
// This must be done after the GL view is assigned to the director!
[director enableRetinaDisplay: YES];;



//_viewController.view.backgroundColor=[UIColor cl];

[AvtaarImageview addSubview:_viewController.view];







CC3Layer* cc3Layer = [cocosnewLayer layerWithController: _viewController];

// Create the customized 3D scene and attach it to the layer.
// Could also just create this inside the customer layer.
cc3Layer.cc3Scene = [cocosnewScene scene];

// Assign to a generic variable so we can uncomment options below to play with the capabilities
CC3ControllableLayer* mainLayer = cc3Layer;

// The 3D layer can run either directly in the scene, or it can run as a smaller "sub-window"
// within any standard CCLayer. So you can have a mostly 2D window, with a smaller 3D window
// embedded in it. To experiment with this smaller embedded 3D window, uncomment the following lines:
//  CGSize winSize = CCDirector.sharedDirector.winSize;
//  cc3Layer.position = ccp(30.0, 30.0);
//  cc3Layer.contentSize = CGSizeMake(winSize.width - 100.0, winSize.width - 40.0);
//  cc3Layer.alignContentSizeWithDeviceOrientation = YES;
//  mainLayer = [CC3ControllableLayer layerWithController: _viewController];
//  [mainLayer addChild: cc3Layer];

// A smaller 3D layer can even be moved around on the screen dyanmically. To see this in action,
// uncomment the lines above as described, and also uncomment the following two lines.
//  cc3Layer.position = ccp(0.0, 0.0);
//  [cc3Layer runAction: [CCMoveTo actionWithDuration: 15.0 position: ccp(500.0, 250.0)]];

// Set the layer in the controller
_viewController.controlledNode = mainLayer;

// Run the layer in the director
CCScene *scene = [CCScene node];
[scene addChild: mainLayer];
[CCDirector.sharedDirector runWithScene: scene];
