isValid

Indicates whether the object is not yet destroyed. (It will not be available after being destroyed)
When an object's destroy is called, it is actually destroyed after the end of this frame. So isValid will return false from the next frame, while isValid in the current frame will still be true. If you want to determine whether the current frame has called destroy, use cc.isValid(obj, true), but this is often caused by a particular logical requirements, which is not normally required.

Examples
var node = new cc.Node();
cc.log(node.isValid);    // true
node.destroy();
cc.log(node.isValid);    // true, still valid in this frame
// after a frame...
cc.log(node.isValid);    // false, destroyed in the end of last frame

meta description
Defined in cocos2d/core/components/CCComponent.js:234
__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.

meta description

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.

meta description
Defined in cocos2d/core/components/CCComponent.js:255
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.

meta description
Defined in cocos2d/core/components/CCComponent.js:268
onEnable

Called when this component becomes enabled and its node is active.

Parameters
  • typeOrClassName Function | String the constructor or the class name of the component to add
Examples
var sprite = node.addComponent(cc.Sprite);
var test = node.addComponent("Test");
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.

meta description
Returns Component
Defined in cocos2d/core/components/CCComponent.js:349
Parameters
Examples
// get sprite component.
var sprite = node.getComponent(cc.Sprite);
// get custom test calss.
var test = node.getComponent("Test");

Returns all components of supplied Type in the node.

meta description
Returns Component[]
Defined in cocos2d/core/components/CCComponent.js:373
Parameters
Examples
var sprites = node.getComponents(cc.Sprite);
var tests = node.getComponents("Test");
getComponentInChildren

meta description
Returns Component
Defined in cocos2d/core/components/CCComponent.js:391
Parameters
Examples
var sprite = node.getComponentInChildren(cc.Sprite);
var Test = node.getComponentInChildren("Test");
getComponentsInChildren

meta description
Returns Component[]
Defined in cocos2d/core/components/CCComponent.js:409
Parameters
Examples
var sprites = node.getComponentsInChildren(cc.Sprite);
var tests = node.getComponentsInChildren("Test");
_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.

meta description
Defined in cocos2d/core/components/CCComponent.js:429
Parameters
  • out_rect Rect the Rect to receive the bounding box
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.

meta description
Defined in cocos2d/core/components/CCComponent.js:536
Parameters
  • callback function The callback function
  • interval Number Tick interval in seconds. 0 means tick every frame.
  • repeat Number The selector will be executed (repeat + 1) times, you can use cc.macro.REPEAT_FOREVER for tick infinitely.
  • delay Number The amount of time that the first tick will wait before execution.
Examples
var timeCallback = function (dt) {
  cc.log("time: " + dt);
}
this.schedule(timeCallback, 1);
scheduleOnce

Schedules a callback function that runs only once, with a delay of 0 or larger.

meta description
Defined in cocos2d/core/components/CCComponent.js:573
Parameters
  • callback function A function wrapped as a selector
  • delay Number The amount of time that the first tick will wait before execution.

meta description
Defined in cocos2d/core/components/CCComponent.js:606
Examples

destroy

Destroy this Object, and release all its own references to other objects.
Actual object destruction will delayed until before rendering. From the next frame, this object is not usable any more. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it.

meta description
Returns Boolean
Defined in cocos2d/core/platform/CCObject.js:293
Examples
obj.destroy();
_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; } } }
