The Addressables system initializes itself at runtime the first time you load an Addressable or make another call to an Addressable API. Call?Addressables.InitializeAsync?to initialize Addressables earlier (this function does nothing if initialization has already occurred).

譯：Addressables系統(tǒng)在您首次加載Addressable或調(diào)用其他Addressable API時在運(yùn)行時初始化自身。調(diào)用Addressables.InitializeAsync以更早地初始化Addressables（如果已經(jīng)初始化，則此函數(shù)不執(zhí)行任何操作）

The initialization operation performs the following tasks:

譯：初始化操作執(zhí)行以下任務(wù)：

• Sets up the?ResourceManager?and the?ResourceLocators.譯：設(shè)置ResourceManager和ResourceLocators。

• Loads configuration data created by Addressables from StreamingAssets.譯：從StreamingAssets加載由Addressables創(chuàng)建的配置數(shù)據(jù)。

• Executes any?initialization object?operations.譯：執(zhí)行任何初始化對象操作。

• Loads the content catalog. By default, Addressables first checks for updates to the content catalog and downloads a new catalog if available.譯：加載內(nèi)容目錄。默認(rèn)情況下，Addressables首先檢查內(nèi)容目錄的更新，并在可用時下載新目錄。

The following Addressables settings can change initialization behavior:

譯：以下Addressables設(shè)置可以更改初始化行為：

• Only update catalogs manually: Addressables won't automatically check for an updated catalog. See?Updating catalogs?for information about manually updating your catalogs.譯：僅手動更新目錄：Addressables不會自動檢查更新的目錄。有關(guān)手動更新目錄的信息，請參見更新目錄。

• Build Remote Catalog: Addressables won't attempt to load remote content without a remote catalog.譯：構(gòu)建遠(yuǎn)程目錄：Addressables不會嘗試加載沒有遠(yuǎn)程目錄的遠(yuǎn)程內(nèi)容。

• Custom certificate handler: identify a custom certificate handler if you need one to access your remote asset hosting service.譯：自定義證書處理程序：如果需要訪問遠(yuǎn)程資產(chǎn)托管服務(wù)，則標(biāo)識自定義證書處理程序。

• Initialization object list: add?IObjectInitializationDataProvider?ScriptableObjects to your application that are invoked during the initialization operation.譯：初始化對象列表：將IObjectInitializationDataProvider ScriptableObjects添加到應(yīng)用程序中，在初始化操作期間調(diào)用它們。

The following runtime properties should be set before the initialization operation starts:

譯：在初始化操作開始之前，應(yīng)設(shè)置以下運(yùn)行時屬性：

• Custom URL transform function譯：自定義URL轉(zhuǎn)換函數(shù)

• ResourceManager exception handler譯：ResourceManager異常處理程序

• Static properties used for any custom runtime placeholders in your?Profile variables譯：在Profile變量中使用任何自定義運(yùn)行時占位符的靜態(tài)屬性

Initialization objects

You can attach objects to the Addressable Assets settings and pass them to the initialization process at runtime. For example, you can create a?CacheInitializationSettings?object to initialize Unity's?Cache?settings at runtime. To create your own types of initialization object, create a ScriptableObject that implements the?IObjectInitializationDataProvider?interface. Use this object to create the?ObjectInitializationData?asset that Addressables includes with your the runtime data.

譯：您可以將對象附加到Addressable Assets設(shè)置并在運(yùn)行時將它們傳遞給初始化進(jìn)程。例如，您可以創(chuàng)建一個CacheInitializationSettings對象，在運(yùn)行時初始化Unity的緩存設(shè)置。要創(chuàng)建自己類型的初始化對象，請創(chuàng)建實(shí)現(xiàn)IObjectInitializationDataProvider接口的ScriptableObject。使用此對象創(chuàng)建ObjectInitializationData資產(chǎn)，Addressables會將其與運(yùn)行時數(shù)據(jù)一起包含。

Cache initialization objects

Use a?CacheInitializationSettings?object to initialize Unity's?Cache?settings at runtime.

譯：使用CacheInitializationSettings對象在運(yùn)行時初始化Unity的緩存設(shè)置。

To specify the cache initialization settings that the Addressables system should use:

譯：要指定Addressables系統(tǒng)應(yīng)使用的緩存初始化設(shè)置：

1. Create the CacheInitializationSettings asset (menu:?Assets > Addressables > Initialization > Cache Initialization Settings).譯：創(chuàng)建CacheInitializationSettings資產(chǎn)（菜單：Assets> Addressables> Initialization> Cache Initialization Settings）

2. Select the new asset file in the Project panel to view the settings in the Inspector?譯：在項(xiàng)目面板中選擇新的資產(chǎn)文件以在檢查器中查看設(shè)置

1. Adjust the settings as desired.譯：根據(jù)需要調(diào)整設(shè)置

2. Open the Addressables Settings Inspector (menu:?Window > Asset Management > Addressables > Settings).譯：打開Addressables設(shè)置檢查器（菜單：Window> Asset Management> Addressables> Settings）

3. In the?Initialization Objects?section of the Inspector, click the?+?button to add a new object to the list.譯：在檢查器的初始化對象部分中，單擊+按鈕以向列表中添加新對象

4. Select your CacheInitializationSettings asset in the File dialog and click?Open.譯：在文件對話框中選擇您的CacheInitializationSettings資產(chǎn)，然后單擊打開

5. The cache settings object is added to the list.?譯：緩存設(shè)置對象將添加到列表中

When Addressables initializes at runtime, it applies these settings to the default Unity?Cache. The settings apply to all AssetBundles in the default cache, not just those downloaded by the Addressables system. See?Caching?for more information about the Unity cache system.

譯：當(dāng)Addressables在運(yùn)行時初始化時，它將這些設(shè)置應(yīng)用于默認(rèn)的Unity緩存。這些設(shè)置適用于默認(rèn)緩存中的所有AssetBundles，而不僅僅是Addressables系統(tǒng)下載的那些。有關(guān)Unity緩存系統(tǒng)的更多信息，請參見緩存

NOTE

Android applications built with Unity 2020.1 or earlier or running on Android 9 or earlier can only play videos from uncompressed AssetBundles. You can use a?CacheInitializationSettings?object to disable recompression of the cache by disabling the?Compress Bundles?option.

譯：使用Unity 202.1或更早版本構(gòu)建的Android應(yīng)用程序或在Android 9或更早版本上運(yùn)行的應(yīng)用程序只能從未壓縮的AssetBundle中播放視頻?？梢允褂肅acheInitializationSettings對象通過禁用壓縮Bundle選項(xiàng)來禁用緩存的重新壓縮。
