# PartyLocalUser::GetEntityId

> 取得與此本機使用者相關聯的 PlayFab 實體識別碼。

取得與此本機使用者相關聯的 PlayFab 實體識別碼。

## 語法

```cpp theme={null}
PartyError GetEntityId(  
    PartyString* entityId  
)  
```

### 參數

**`entityId`**   [PartyString\*](/zh-TW/services/playfab/multiplayer/networking/reference/typedefs)\
*library-allocated output*

使用者的輸出實體識別碼。

### 傳回值

PartyError

`c_partyErrorSuccess` (如果呼叫成功)，否則為錯誤碼。可透過 [PartyManager::GetErrorMessage()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_geterrormessage) 擷取錯誤碼的人類可讀形式。

## 備註

擷取的 PlayFab 實體識別碼與遊戲透過 [PartyManager::CreateLocalUser()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_createlocaluser) 或 [PartyManager::CreateLocalUserWithEntityType()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_createlocaluserwithentitytype) 提供的實體識別碼相同。這也與代表該實體之 `PFEntityKey` 結構的 *id* 欄位中的值相同。[GetEntityType()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyLocalUser/methods/partylocaluser_getentitytype) 傳回的值則代表 `PFEntityKey` 的另一半。 \
\
 實體識別碼字串的記憶體在本機使用者的存留期間內保持有效，也就是直到 [PartyManager::StartProcessingStateChanges()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_startprocessingstatechanges) 提供其 [PartyDestroyLocalUserCompletedStateChange](/zh-TW/services/playfab/multiplayer/networking/reference/structs/partydestroylocalusercompletedstatechange)，且所有參考該本機使用者的狀態變更都已傳回給 [PartyManager::FinishProcessingStateChanges()](/zh-TW/services/playfab/multiplayer/networking/reference/classes/PartyManager/methods/partymanager_finishprocessingstatechanges) 為止。
