当我从视图控制器调用动画时，我试图在视图控制器上调用 cocos3d 动画，然后出现错误。
" cocos2d: Using Director Type:CCDirectorTimer [ ERROR ] cocos23Layer 需要一个控制器来渲染 3D 场景。2013-08-29 11:54:56.419 MaskedCal[3854:c07] * -[cocos23Layer initWithController:], /Users 中的断言失败/34in/桌面/cocos23/cocos23/cocos23/cocos3d/cocos3d/Scenes/CC3Layer.m:74"
这是我的视图控制器，我想在其中调用我的 cocos3d 动画

// Select an appropriate shader program for each mesh node in this scene now. If this step

// 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.

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

// 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.
