Unity NGUI的Anchors編程

有些時候需要動態改變Left , Right , Bottom ,Top的值.有這樣需求的游戲非常的多,比如:需要移位一個Panel零時加入另一個Panel(操作工具)面板.

舉個例子 , 游戲中 , 對每個玩家的操作都有時間限制 . 這樣,對各個玩家的時間提醒,就可以用一個鬧鐘類,只需要改變它的Anchors和坐標就行了

舉個栗子:

    /// <summary>
    /// 設置鬧鐘位置
    /// </summary>
    /// <param name="_userID">用戶座位ID</param>
    public void SetAlarmClockPos( ushort _chairID )
    {
        if (this.chairID != _chairID)
        {
            if (this._sprite == null) this._sprite = gameObject.GetComponent<UISprite>();
            this.chairID = _chairID;
            ushort _pos = Defines.SwapViewID(this.chairID);
            this._sprite.GetComponent<UIWidget>().enabled = false;
            switch (_pos)
            {
                case 0://我自己
                    this.gameObject.transform.localPosition = new Vector3(-375, -384, 0);
                    this._sprite.leftAnchor.relative = 1;
                    this._sprite.leftAnchor.absolute = -339;
                    this._sprite.rightAnchor.relative = 1;
                    this._sprite.rightAnchor.absolute = -277;
                    this._sprite.bottomAnchor.relative = 0;
                    this._sprite.bottomAnchor.absolute = 12;
                    this._sprite.topAnchor.relative = 0;
                    this._sprite.topAnchor.absolute = 94;
                    break;
                case 1://左上
                    this.gameObject.transform.localPosition = new Vector3(-412, 387, 0);
                    this._sprite.leftAnchor.relative = 1;
                    this._sprite.leftAnchor.absolute = -302;
                    this._sprite.rightAnchor.relative = 1;
                    this._sprite.rightAnchor.absolute = -240;
                    this._sprite.bottomAnchor.relative = 1;
                    this._sprite.bottomAnchor.absolute = -91;
                    this._sprite.topAnchor.relative = 1;
                    this._sprite.topAnchor.absolute = -9;
                    break;
                case 2://右上
                    this.gameObject.transform.localPosition = new Vector3( -412 , 387 , 0 );
                    this._sprite.leftAnchor.relative = 0;
                    this._sprite.leftAnchor.absolute = 240;
                    this._sprite.rightAnchor.relative = 0;
                    this._sprite.rightAnchor.absolute = 302;
                    this._sprite.bottomAnchor.relative = 1;
                    this._sprite.bottomAnchor.absolute = -91;
                    this._sprite.topAnchor.relative = 1;
                    this._sprite.topAnchor.absolute = -9;
                    break;
                default:
                    if (gameObject.activeSelf) gameObject.SetActive(false);
                    this.Stop();
                    break;
            }
            this._sprite.GetComponent<UIWidget>().enabled = true;
        }
    }

在操作Anchors時 , 一定要記住:

 this._sprite.GetComponent<UIWidget>().enabled = false;

將Widget設為不可用.

另外 : 設置其坐標

在這里需要指出的是 : relative , absolute

relative : 指出的是相對于那邊停靠

記住 : 左 -> 中 - > 右 / 下->中->上  一次是 0 , 0,5 , 1

關于absolute 這是 后面的值(相對的)

再將Widget設為可用.
