isDefaultMatrix

  • get isDefaultMatrix(): boolean

    返回 boolean

    En

    Whether it is the default matrix. If true, it indicates that there is no change relative to the parent node, and calculations will be skipped based on this parameter.

    Zh

    是否为默认矩阵，如果为true，表示自身相对于父节点并无任何改变，将通过这个参数忽略计算。

方法

event

  • event(type: string, data?: any): boolean

    参数

    • type: string

      The type of event.

    • 可选data: any

      (Optional) Data to pass to the callback. If multiple parameters p1, p2, p3, ... need to be passed, use an array structure such as [p1, p2, p3, ...]. If a single parameter p needs to be passed and p is an array, use a structure such as [p]. For other single parameters p, you can directly pass parameter p. If data is Event.EMPTY, it means passing an Event object to the callback function. Note that it is not passing Event.TEMP, but an independent Event object.

    返回 boolean

    True if there are listeners for this event type, false otherwise.

    En

    Dispatch an event.

    Zh

    派发事件。

getForward

getFrontFaceValue

getRight

getUp

getWorldLossyScale

  • getWorldLossyScale(): Vector3

    返回 Vector3

    The world scale.

    En

    The world scale. Under certain conditions, obtaining this value may not be accurate (e.g., when the parent node has scaling and the child node has rotation). The scaling may be skewed and cannot be correctly represented using Vector3. A Matrix3x3 matrix must be used for correct representation.

    Zh

    世界缩放。 某种条件下获取该值可能不正确（例如：父节点有缩放，子节点有旋转）。 缩放会倾斜，无法使用Vector3正确表示，必须使用Matrix3x3矩阵才能正确表示。
