Skeleton Class

Extends _RendererUnderSG

Module: sp

The skeleton of Spine

(Skeleton has a reference to a SkeletonData and stores the state for skeleton instance, which consists of the current pose's bone SRT, slot colors, and which slot attachments are visible.
Multiple skeletons can use the same SkeletonData which includes all animations, skins, and attachments.)

  This method is different from the skeletonData property. This method is passed in the raw data provided by the Spine runtime, and the skeletonData type is the asset type provided by Creator.

  The parameter type is sp.spine.AnimationStateData.
• setMix Mix applies all keyframe values, interpolated for the specified time and mixed with the current values.

• setTrackDisposeListener Set the dispose event listener for specified TrackEntry (only supported on Web).
• setTrackCompleteListener Set the complete event listener for specified TrackEntry (only supported on Web).
• setTrackEventListener Set the event listener for specified TrackEntry (only supported on Web).
• _createSgNode Create and returns your new scene graph node (SGNode) to add to scene graph. You should call the setContentSize of the SGNode if its size should be the same with the node's.
• _initSgNode
• _removeSgNode
• update Update is called every frame, if the Component is enabled.
• lateUpdate LateUpdate is called every frame, if the Component is enabled.
• __preload __preload is called before every onLoad. It is used to initialize the builtin components internally, to avoid checking whether onLoad is called before every public method calls. This method should be removed if script priority is supported.
• onLoad When attaching to an active node or its node first activated. onLoad is always called before any start functions, this allows you to order initialization of scripts.
• start Called before all scripts' update if the Component is enabled the first time. Usually used to initialize some logic which need to be called after all components' onload methods called.
• onEnable Called when this component becomes enabled and its node is active.
• onDisable Called when this component becomes disabled or its node becomes inactive.
• onDestroy Called when this component will be destroyed.
• onFocusInEditor
• onLostFocusInEditor
• resetInEditor Called to initialize the component or node’s properties when adding the component the first time or when the Reset command is used. This function is only called in editor.
• addComponent Adds a component class to the node. You can also add component to node by passing in the name of the script.
• getComponent Returns the component of supplied type if the node has one attached, null if it doesn't.
  You can also get component in the node by passing in the name of the script.
• getComponents Returns all components of supplied Type in the node.
• getComponentInChildren Returns the component of supplied type in any of its children using depth first search.
• getComponentsInChildren Returns the components of supplied type in self or any of its children using depth first search.
• _getLocalBounds If the component's bounding box is different from the node's, you can implement this method to supply a custom axis aligned bounding box (AABB), so the editor's scene view can perform hit test properly.
• onRestore onRestore is called after the user clicks the Reset item in the Inspector's context menu or performs an undo operation on this component.
  
  If the component contains the "internal state", short for "temporary member variables which not included
  in its CCClass properties", then you may need to implement this function.
  
  The editor will call the getset accessors of your component to record/restore the component's state
  for undo/redo operation. However, in extreme cases, it may not works well. Then you should implement
  this function to manually synchronize your component's "internal states" with its public properties.
  Once you implement this function, all the getset accessors of your component will not be called when
  the user performs an undo/redo operation. Which means that only the properties with default value
  will be recorded or restored by editor.
  
  Similarly, the editor may failed to reset your component correctly in extreme cases. Then if you need
  to support the reset menu, you should manually synchronize your component's "internal states" with its
  properties in this function. Once you implement this function, all the getset accessors of your component
  will not be called during reset operation. Which means that only the properties with default value
  will be reset by editor.

This function is only called in editor mode.

• schedule Schedules a custom selector.
  If the selector is already scheduled, then the interval parameter will be updated without scheduling it again.
• scheduleOnce Schedules a callback function that runs only once, with a delay of 0 or larger.
• unschedule Unschedules a custom callback function.
• unscheduleAllCallbacks unschedule all scheduled callback functions: custom callback functions, and the 'update' callback function.
  Actions are not affected by this method.
• destroy Destroy this Object, and release all its own references to other objects.
  Actual object destruction will delayed until before rendering.
  After destroy, this CCObject is not usable any more. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it.
• _destruct Clear all references in the instance.

NOTE: this method will not clear the getter or setter functions which defined in the instance of CCObject. You can override the _destruct method if you need, for example: _destruct: function () { for (var key in this) { if (this.hasOwnProperty(key)) { switch (typeof this[key]) { case 'string': this[key] = ''; break; case 'object': case 'function': this[key] = null; break; } } }

• _onPreDestroy Called before the object being destroyed.
• _serialize The customized serialization for this object. (Editor Only)
• _deserialize Init this object from the custom serialized data.
