Asset Class

Extends RawAsset

Module: cc

Base class for handling assets used in Fireball. This class can be instantiate.

You may want to override:

• createNode
  
• cc.Object._serialize
  
• cc.Object._deserialize
  

Index

Properties

• rawUrl String Returns the url of this asset's first raw file, if none of rawFile exists, it will returns an empty string.
• rawUrls String[] Returns the url of this asset's raw files, if none of rawFile exists, it will returns an empty array.
• _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。
• preventDeferredLoadDependents Boolean Indicates whether its dependent raw assets can support deferred load if the owner scene (or prefab) is marked as asyncLoadAssets.
• _uuid String
• _name String
• _objFlags Number
• name String The name of the object.
• isValid Boolean Indicates whether the object is not yet destroyed.

Methods

• deserialize 应 AssetDB 要求提供这个方法
• serialize 应 AssetDB 要求提供这个方法
• createNode Create a new node using this asset in the scene.
  If this type of asset dont have its corresponding node type, this method should be null.
• _setRawFiles Set raw file names for this asset.
• _preloadRawFiles Preload raw files when loading scene.
• 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.

Properties

rawUrl

Returns the url of this asset's first raw file, if none of rawFile exists, it will returns an empty string.

rawUrls

Returns the url of this asset's raw files, if none of rawFile exists, it will returns an empty array.

_rawFiles

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。

preventDeferredLoadDependents

Indicates whether its dependent raw assets can support deferred load if the owner scene (or prefab) is marked as asyncLoadAssets.

_uuid

_name

_objFlags

name

The name of the object.

Examples

obj.name = "New Obj";

isValid

Indicates whether the object is not yet destroyed.

Examples

cc.log(obj.isValid);

Methods

deserialize

应 AssetDB 要求提供这个方法

Parameters

• data String

serialize

应 AssetDB 要求提供这个方法

createNode

Create a new node using this asset in the scene.
If this type of asset dont have its corresponding node type, this method should be null.

Parameters

• callback Function
  • error String null or the error info
  • node Object the created node or null

_setRawFiles

Set raw file names for this asset.

Parameters

• rawFiles String[]

_preloadRawFiles

Preload raw files when loading scene.

Parameters

• callback Function
  • error Error

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.

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; } } }

_onPreDestroy

Called before the object being destroyed.

_serialize

The customized serialization for this object. (Editor Only)

Parameters

• exporting Boolean

_deserialize

Init this object from the custom serialized data.

Parameters

• data Object the serialized json data
• ctx _Deserializer
