# PFLobbyMemberAddedStateChange

> MemberAdded PlayFab 多人游戏状态变更详细信息，在远程或本地客户端向大厅添加新成员时引发。

*MemberAdded* 类型状态变更的特定信息。

## 语法

```cpp theme={null}
struct PFLobbyMemberAddedStateChange : PFLobbyStateChange {  
    PFLobbyHandle lobby;  
    PFEntityKey member;  
}  
```

### 成员

**`lobby`**   PFLobbyHandle\
*must not be null*

添加了新成员的大厅。

**`member`**   [PFEntityKey](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pfmultiplayer/pfentitykey_clientsdk.md)

现已成为大厅成员的 PlayFab 实体。

## 备注

所有向大厅添加成员的操作都会生成此状态变更，例如 [PFMultiplayerCreateAndJoinLobby](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayercreateandjoinlobby.md)、[PFMultiplayerJoinLobby](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerjoinlobby.md) 和 [PFLobbyAddMember](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pflobbyaddmember.md)。\
\
 当 [PFMultiplayerStartProcessingLobbyStateChanges](https://docs.xbox.com/zh-CN/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerstartprocessinglobbystatechanges.md) 提供此状态变更时，大厅将进行更新以在成员列表中反映新成员，且该成员的初始属性将变为可查询。
