        Vector2 screenPoint = Camera.main.WorldToScreenPoint(position);//世界坐標轉換為屏幕坐標
        Vector2 screenSize = new Vector2(Screen.width, Screen.height);
        screenPoint -= screenSize / 2;//將屏幕坐標變換為以屏幕中心為原點
        Vector2 anchorPos = screenPoint / screenSize * rectTrans.sizeDelta;//縮放得到UGUI坐標
        return anchorPos;
    }
}

這里的numList[i].target，是Tween.target。是調用DOLocalMoveY的對象。所以這里是個Transform。

這里還有一個世界轉UGUI的方法。
