属性(properties)

_createFunction

Cache function to optimize instance creaton.

meta description
类型 Function
定义于 cocos2d/core/assets/CCPrefab.js:85
data

the main cc.Node in the prefab

meta description
类型 Node
定义于 cocos2d/core/assets/CCPrefab.js:96
optimizationPolicy

设置实例化这个 prefab 时所用的优化策略。根据使用情况设置为合适的值,能优化该 prefab 实例化所用的时间。

meta description
类型 Prefab.OptimizationPolicy
定义于 cocos2d/core/assets/CCPrefab.js:101
添加于 1.10.0
示例
prefab.optimizationPolicy = cc.Prefab.OptimizationPolicy.MULTI_INSTANCE;
asyncLoadAssets

指示该 Prefab 依赖的资源可否在 Prefab 加载后再延迟加载。

meta description
类型 Boolean
定义于 cocos2d/core/assets/CCPrefab.js:116
loaded

该资源是否已经成功加载

meta description
类型 Boolean
定义于 cocos2d/core/assets/CCAsset.js:57
nativeUrl

返回该资源对应的目标平台资源的 URL,如果没有将返回一个空字符串。

meta description
类型 String
定义于 cocos2d/core/assets/CCAsset.js:70
_native

Serializable url for native asset.

meta description
类型 String
定义于 cocos2d/core/assets/CCAsset.js:108
_nativeAsset

The underlying native asset of this asset if one is available. This property can be used to access additional details or functionality releated to the asset. This property will be initialized by the loader if _native is available.

meta description
类型 Object
定义于 cocos2d/core/assets/CCAsset.js:116
_uuid
meta description
类型 String
定义于 cocos2d/core/assets/CCRawAsset.js:46
_name
meta description
类型 String
定义于 cocos2d/core/platform/CCObject.js:76
_objFlags
meta description
类型 Number
定义于 cocos2d/core/platform/CCObject.js:83
name

该对象的名称。

meta description
类型 String
定义于 cocos2d/core/platform/CCObject.js:243
示例
obj.name = "New Obj";
isValid

表示该对象是否可用(被 destroy 后将不可用)。
当一个对象的 destroy 调用以后,会在这一帧结束后才真正销毁。因此从下一帧开始 isValid 就会返回 false,而当前帧内 isValid 仍然会是 true。如果希望判断当前帧是否调用过 destroy,请使用 cc.isValid(obj, true),不过这往往是特殊的业务需求引起的,通常情况下不需要这样。

meta description
类型 Boolean
定义于 cocos2d/core/platform/CCObject.js:261
示例
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

方法

compileCreateFunction

Dynamically translation prefab data into minimized code.
This method will be called automatically before the first time the prefab being instantiated, but you can re-call to refresh the create function once you modified the original prefab data in script.

meta description
定义于 cocos2d/core/assets/CCPrefab.js:136
toString

Returns the asset's url.

The Asset object overrides the toString() method of the Object object. For Asset objects, the toString() method returns a string representation of the object. JavaScript calls the toString() method automatically when an asset is to be represented as a text value or when a texture is referred to in a string concatenation.

meta description
返回 String
定义于 cocos2d/core/assets/CCAsset.js:165
serialize

应 AssetDB 要求提供这个方法

meta description
返回 String
定义于 cocos2d/core/assets/CCAsset.js:179
createNode

使用该资源在场景中创建一个新节点。
如果这类资源没有相应的节点类型,该方法应该是空的。

meta description
定义于 cocos2d/core/assets/CCAsset.js:190
参数列表
_setRawAsset

Set native file name for this asset.

meta description
定义于 cocos2d/core/assets/CCAsset.js:205
参数列表
destroy

销毁该对象,并释放所有它对其它对象的引用。
实际销毁操作会延迟到当前帧渲染前执行。从下一帧开始,该对象将不再可用。 您可以在访问对象之前使用 cc.isValid(obj) 来检查对象是否已被销毁。

meta description
返回 Boolean
定义于 cocos2d/core/platform/CCObject.js:296
示例
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; } } }

meta description
定义于 cocos2d/core/platform/CCObject.js:430
_onPreDestroy

Called before the object being destroyed.

meta description
定义于 cocos2d/core/platform/CCObject.js:463
_serialize

The customized serialization for this object. (Editor Only)

meta description
返回 object
定义于 cocos2d/core/platform/CCObject.js:488
参数列表
_deserialize

Init this object from the custom serialized data.

meta description
定义于 cocos2d/core/platform/CCObject.js:498
参数列表
  • data Object the serialized json data
  • ctx _Deserializer
