Transform.GetChild

参数

返回

Transform 索引位置处的变换子项。

描述

按索引返回变换子项。

如果该变换没有子项，或者 index 参数的值大于子项数，则会生成错误。在这种情况下，将给出“Transform child out of bounds”错误。子项数可以由 childCount 提供。

    {
        //Assigns the transform of the first child of the Game Object this script is attached to.
        meeple = this.gameObject.transform.GetChild(0);

        //Assigns the first child of the first child of the Game Object this script is attached to.
        grandChild = this.gameObject.transform.GetChild(0).GetChild(0).gameObject;
    }
