property

{Boolean} preventDeferredLoadDependents

default

false

Static preventPreloadNativeObject

preventPreloadNativeObject: boolean = false

禁止预加载原生对象。

property

{Boolean} preventPreloadNativeObject

default

false

Accessors

Private nativeAsset

  • get nativeAsset(): any
  • set nativeAsset(obj: any): void

height

  • get height(): number

isCompressed

  • get isCompressed(): boolean

isValid

  • get isValid(): boolean
  • 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。

    property

    {Boolean} isValid

    default

    true

    readonly
    example
    import * as cc from 'cc';
    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

    Returns boolean

name

  • get name(): string
  • set name(value: string): void

nativeUrl

  • get nativeUrl(): string
  • 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。

    property

    nativeUrl

    type

    {String}

    readonly

    Returns string

width

  • get width(): number

Methods

deserialize

  • deserialize(serializedData: any, handle: any): void

destroyImmediate

  • _destroyImmediate(): void

destruct

  • _destruct(): void
  • 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; } } }

    Returns void

Protected getGFXDevice

Protected getGFXFormat

  • _getGFXFormat(): number

serialize

  • serialize(exporting?: any): any

Protected setGFXFormat

Private setRawAsset

  • setRawAsset(filename: string, inLibrary?: boolean): void

Optional createNode

destroy

  • destroy(): boolean

dispatchEvent

  • dispatchEvent(event: Event): void

emit

  • emit(key: string, ...args: any[]): void

getAnisotropy

  • getAnisotropy(): number

getGFXSampler

getGFXTextureView

getId

  • getId(): string

getPixelFormat

  • getPixelFormat(): number

Private getSamplerHash

  • getSamplerHash(): number

hasEventListener

  • hasEventListener(key: string, callback?: Function | undefined, target?: Object | undefined): boolean

hasPremultipliedAlpha

  • hasPremultipliedAlpha(): boolean

off

  • off(type: string, callback?: Function | undefined, target?: Object | undefined): void

on

  • on(type: string, callback: Function, target?: Object | undefined): Function | undefined

once

  • once(type: string, callback: Function, target?: Object | undefined): Function | undefined

removeAll

  • removeAll(keyOrTarget?: string | Object | undefined): void

Private serialize

  • serialize(): void

setAnisotropy

  • setAnisotropy(anisotropy: number): void

setFilters

setFlipY

  • setFlipY(flipY: boolean): void

setMipFilter

  • setMipFilter(mipFilter: Filter): void

setPremultiplyAlpha

  • setPremultiplyAlpha(premultiply: boolean): void

setWrapMode

  • 设置此贴图的缠绕模式。 注意,若贴图尺寸不是 2 的整数幂,缠绕模式仅允许 WrapMode.CLAMP_TO_EDGE

    Parameters

    • wrapS: WrapMode

      S(U) 坐标的采样模式。

    • wrapT: WrapMode

      T(V) 坐标的采样模式。

    • Optional wrapR: WrapMode

      R(W) 坐标的采样模式。

    Returns void

targetOff

  • targetOff(keyOrTarget?: string | Object | undefined): void

toString

  • toString(): string
  • 返回对象的字符串表示形式。
    Asset 对象将会重写 Object 对象的 toString() 方法。
    当资源要表示为文本值时或在字符串连接时引用时,
    JavaScript 会自动调用 toString() 方法。

    对于原始类型的资源,它将返回this.nativeUrl
    否则,返回空字符串。
    子类可能会覆盖此方法。

    method

    toString

    Returns string

Static deferredDestroy

  • _deferredDestroy(): void

Static deserialize

  • deserialize(data: any): any

Static isRawAssetType

  • isRawAssetType(ctor: Function): boolean
