unityUI弹出提醒框的实现

比如这样：

取消子物体活性后如下图：

GameObject warnobj;
GameObject warnUI;//子物体
 warnobj = GameObject.Find("Warnobj");// 获取父物体

 warnUI = warnobj.transform.Find("Warn").gameObject;

 warnUI.SetActive(true);
 enableFPS.enabled = false;
 Cursor.lockState = CursorLockMode.None;
 Cursor.visible = true;
