# 类: GroupMessageEvent

[(返回目录)](/api.md)

**继承自:** [MessageEvent](/api/messageevent.md)

RainyBot的群组消息事件类，其实例记录了与一次群组消息事件相关的数据

## 方法

* static [GroupMessageEvent](/api/groupmessageevent.md) **init\_meta (** [Dictionary](https://docs.godotengine.org/en/latest/classes/class_dictionary.html) dic **)**

通过机器人协议后端的元数据字典构造一个此类的实例，仅当你知道自己在做什么时才使用

***

* [GroupMember](/api/groupmember.md) **get\_sender ( )**

获取消息事件对应的发送者的群组成员实例

***

* [Group](/api/group.md) **get\_group ( )**

获取消息事件所对应的群组的实例

***

* [int](https://docs.godotengine.org/en/latest/classes/class_int.html) **get\_group\_id ( )**

获取消息事件所对应的群组的ID

***

* [BotRequestResult](/api/botrequestresult.md) **recall (** [float](https://docs.godotengine.org/en/latest/classes/class_float.html) timeout=-INF **)**

撤回事件所对应的群消息，机器人需要在对应群组中为管理员或群组权限才能执行成功

配合await关键字可返回一个BotRequestResult类的实例，便于判断执行状态

可以通过指定timeout参数来自定义获取请求结果的超时时间，若不指定则默认将使用配置文件中设置的超时时间

***

* [BotRequestResult](/api/botrequestresult.md) **set\_essence (** [float](https://docs.godotengine.org/en/latest/classes/class_float.html) timeout=-INF **)**

将事件所对应的群消息设置为精华消息，机器人需要在对应群组中为管理员或群组权限才能执行成功

配合await关键字可返回一个BotRequestResult类的实例，便于判断执行状态

可以通过指定timeout参数来自定义获取请求结果的超时时间，若不指定则默认将使用配置文件中设置的超时时间

***

* [bool](https://docs.godotengine.org/en/latest/classes/class_bool.html) **is\_at\_bot ( )**

判断事件所对应的群消息中是否AT了机器人
