        eventData.position = Input.mousePosition;
        List<RaycastResult> list = new List<RaycastResult>();
        foreach (var item in graphicRaycasters)
        {
            item.Raycast(eventData, list);
            if (list.Count > 0)
            {

                {
                    objs.Add(list[i].gameObject.transform);
