Prefab
类型
继承于 Asset
模块: cc
预制资源类。
索引
属性(properties)
data
Node
the main cc.Node in the prefabasyncLoadAssets
Boolean
指示该 Prefab 依赖的资源可否在 Prefab 加载后再延迟加载。_createFunction
Function
Cache function for fast instantiationrawUrl
String
返回该资源的原始文件的 URL,如果不支持 RAW 文件,它将返回一个空字符串。rawUrls
String[]
返回该资源的原文件的 URL 数组,如果不支持 RAW 文件,它将返回一个空数组。_rawFiles
String[]
在 lite 版的 Fireball 里,raw asset 并不仅仅是在 properties 里声明了 rawType 才有, 而是每个 asset 都能指定自己的 raw file url。这些 url 就存在 _rawFiles 字段中。 AssetLibrary 并不会帮你加载这些 url,除非你声明了 rawType。 在 Creator 里,_rawFiles 保留了下来,为了复用 cocos 引擎原有实现,直接用 _rawFiles 来加载 Asset 在 import 之前的源文件。_uuid
String
_name
String
_objFlags
Number
name
String
该对象的名称。isValid
Boolean
表示该对象是否可用(被销毁后将不可用)。
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.serialize
应 AssetDB 要求提供这个方法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。_setRawFiles
Set raw file names for this asset._preloadRawFiles
Preload raw files when loading scene.destroy
销毁该对象,并释放所有它对其它对象的引用。
销毁后,CCObject 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。 实际销毁操作会延迟到当前帧渲染前执行。_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.
