Class Scene

cc.Scene 是 cc.BaseNode 的子类，仅作为一个抽象的概念。
cc.Scene 和 cc.BaseNode 有点不同，用户不应直接修改 cc.Scene。

activeInHierarchy

  • get activeInHierarchy(): boolean

children

  • get children(): this[]

  • 节点的所有子节点。

    property

    children

    type

    {Node[]}

    readonly
    example

    Returns this[]

components

eulerAngles

  • get eulerAngles(): Readonly<Vec3>

eventProcessor

globals

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
