# PFLobbyStateChange

> 代表 PlayFab Multiplayer Lobby 程式庫所傳遞之事件或狀態變更的一般基底結構，用於分派特定的衍生變更。

Lobby 程式庫中事件或狀態變更的一般基底結構表示法。

## 語法

```cpp theme={null}
struct PFLobbyStateChange {  
    PFLobbyStateChangeType stateChangeType;  
}  
```

### 成員

**`stateChangeType`**   [PFLobbyStateChangeType](/zh-TW/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/enums/pflobbystatechangetype)

所代表之狀態變更的特定類型。

使用此欄位判斷此 PFLobbyStateChange 結構標頭代表哪個對應的衍生結構。

## 備註

PFLobbyStateChange 結構由 [PFMultiplayerStartProcessingLobbyStateChanges()](/zh-TW/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerstartprocessinglobbystatechanges) 回報，供遊戲處理後再透過 [PFMultiplayerFinishProcessingLobbyStateChanges()](/zh-TW/services/playfab/multiplayer/lobby/playfabmultiplayerreference-cpp/pflobby/functions/pfmultiplayerfinishprocessinglobbystatechanges) 方法迅速傳回。<br /><br /> `stateChangeType` 欄位表示發生了哪種狀態變更，接著應將此基底結構轉換為更具體的衍生結構，以擷取其他事件專屬資訊。

## 需求

**標頭：** PFLobby.h
