Accessors

scriptAsset

  • get scriptAsset(): null

isOnLoadCalled

  • get isOnLoadCalled(): number

alphaThreshold

  • get alphaThreshold(): number
  • set alphaThreshold(value: number): void
  • The alpha threshold.(Not supported Canvas Mode)
    The content is drawn only where the stencil have pixel with alpha greater than the alphaThreshold.
    Should be a float between 0 and 1.
    This default to 0.1. When it's set to 1, the stencil will discard all pixels, nothing will be shown.

    Returns number

  • The alpha threshold.(Not supported Canvas Mode)
    The content is drawn only where the stencil have pixel with alpha greater than the alphaThreshold.
    Should be a float between 0 and 1.
    This default to 0.1. When it's set to 1, the stencil will discard all pixels, nothing will be shown.

    Parameters

    • value: number

    Returns void

blendHash

  • get blendHash(): number

color

  • get color(): Readonly<Color>
  • set color(value: {}): void

customMaterial

  • get customMaterial(): null | Material

enabled

  • get enabled(): boolean
  • set enabled(value: boolean): void

graphics

inverted

  • get inverted(): boolean
  • set inverted(value: boolean): void

isValid

  • get isValid(): boolean
  • 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 isValid(obj, true), but this is often caused by a particular logical requirements, which is not normally required.

    default

    true

    readonly
    example
    import { Node, log } from 'cc';
    const node = new Node();
    log(node.isValid);    // true
    node.destroy();
    log(node.isValid);    // true, still valid in this frame
    // after a frame...
    log(node.isValid);    // false, destroyed in the end of last frame

    Returns boolean
