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

Methods

Optional Private preload

  • __preload(): void

  • __preload is called before every onLoad.
    It is used to initialize the builtin components internally,
    to avoid checking whether onLoad is called before every public method calls.
    This method should be removed if script priority is supported.

    Returns 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

Optional Private getLocalBounds

  • getLocalBounds(out_rect: Rect): void

  • If the component's bounding box is different from the node's, you can implement this method to supply a custom axis aligned bounding box (AABB), so the editor's scene view can perform hit test properly.

      The rect to store the result bounding rect

Protected Optional lateUpdate

  • lateUpdate(dt: number): void

  • LateUpdate is called every frame, if the Component is enabled.
    This is a lifecycle method. It may not be implemented in the super class.
    You can only call its super class method inside it. It should not be called manually elsewhere.

    Parameters

    • dt: number

      the delta time in seconds it took to complete the last frame

    Returns void

Protected onDestroy

  • onDestroy(): void

Protected onDisable

  • onDisable(): void

Protected onEnable

  • onEnable(): void

Optional onFocusInEditor

  • onFocusInEditor(): void

Protected onLoad

  • onLoad(): void

Optional onLostFocusInEditor

  • onLostFocusInEditor(): void

Protected Optional onRestore

  • onRestore(): void

  • onRestore is called after the user clicks the Reset item in the Inspector's context menu or performs an undo operation on this component.

    If the component contains the "internal state", short for "temporary member variables which not included
    in its CCClass properties", then you may need to implement this function.

    The editor will call the getset accessors of your component to record/restore the component's state
    for undo/redo operation. However, in extreme cases, it may not works well. Then you should implement
    this function to manually synchronize your component's "internal states" with its public properties.
    Once you implement this function, all the getset accessors of your component will not be called when
    the user performs an undo/redo operation. Which means that only the properties with default value
    will be recorded or restored by editor.

    Similarly, the editor may failed to reset your component correctly in extreme cases. Then if you need
    to support the reset menu, you should manually synchronize your component's "internal states" with its
    properties in this function. Once you implement this function, all the getset accessors of your component
    will not be called during reset operation. Which means that only the properties with default value
    will be reset by editor.

    This function is only called in editor mode.

    Returns void

removeMask

  • removeMask(v: number): void

Optional resetInEditor

schedule

  • schedule(callback: any, interval?: number, repeat?: number, delay?: number): void

    import { log } from 'cc';
this.schedule((dt) => void log(`time: ${dt}`), 1);
