UGUI之判断是否点在UI上

if (Input.touchSupported) {if (Input.touchCount > 0) {if(Input.touches[0].phase== TouchPhase.Began){if (EventSystem.current.IsPointerOverGameObject (Input.GetTouch (0).fingerId))isOnGUGI = true;}} else {isOnGUGI = false;}} else {if (Input.GetMouseButtonDown (0)) {if (EventSystem.current.IsPointerOverGameObject ())isOnGUGI = true;} else if (Input.GetMouseButtonUp (0)) {isOnGUGI = false;}}

简单的处理方式，需要在Resources文件夹下面先放一个EventSystem的Prefab
