TileMap的格子坐标转FUI的世界坐标

    FairyGUI.GComponent com = null;
    Vector3Int cell_pos = new Vector3Int(mapBuildDataBase.position_x, mapBuildDataBase.position_y, -4);

    Debug.Log("执行了这里"+ mapBuildDataBase.id);
    if(!BuildingComList.ContainsKey(mapBuildDataBase.id))
    {
        Debug.Log("没执行了这里" + mapBuildDataBase.id);
        com = FairyGUI.UIPackage.CreateObject("Res_Compontent", "CountDownBuild").asCom;
        //com.displayObject.layer = LayerMask.NameToLayer("CtiyTime");
        BuildingComList.Add(mapBuildDataBase.id, com);
        GameZootoPia._Instance.MainCom.AddChild(com);
        Vector3 worldPos = GoodsLayer.CellToWorld(cell_pos);    // 格子的世界坐标
    Vector3 screenPos = FairyGUI.StageCamera.main.WorldToScreenPoint(worldPos);    // 格子的屏幕坐标
    screenPos.y = Screen.height - screenPos.y;   //原点位置转换
        Vector2 pt = FairyGUI.GRoot.inst.GlobalToLocal(screenPos);          //转换世界空间的坐标到UI里的坐标
    pt.x = pt.x - 120f;
