There is an asset in the store I grabbed. the coding is WAY above my head, I got about half of it and integrated and adapted what I can to it. im going as far as I can with it and ill come back in a few month when I understand t better.

# Customizing Addressables initialization
|
|
|
|
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).
|
|
|
|
The initialization operation performs the following tasks:
|
|
|
|
* Sets up the [ResourceManager] and the [ResourceLocators].
|
|
* Loads configuration data created by Addressables from StreamingAssets.
|
|
* Executes any [initialization object] operations.
|
|
* Loads the content catalog. By default, Addressables first checks for updates to the content catalog and downloads a new catalog if available.
|
|
|
|
The following Addressables settings can change initialization behavior:
|
|
|
|
* [Disable Catalog Update on Startup]: Addressables won't automatically check for an updated catalog. See [Updating catalogs] for information about manually updating your catalogs.
|
|
* [Build Remote Catalog]: Addressables won't attempt to load remote content without a remote catalog.
|
|
* [Custom certificate handler]: identify a custom certificate handler if you need one to access your remote asset hosting service.
|
|
* [Initialization object list]: add [IObjectInitializationDataProvider] ScriptableObjects to your application that are invoked during the initialization operation.
|
|
|
|
The following runtime properties should be set before the initialization operation starts:
|
|
|
|
* [Custom URL transform function]
|
|
* [ResourceManager exception handler]
|
|
* Static properties used for any custom runtime placeholders in your [Profile variables]
|
|
|
|
### 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.
|
|
|
|
### Cache initialization objects
|
|
|
|
Use a [CacheInitializationSettings] object to initialize Unity's [Cache] settings at runtime.
|
|
|
|
To specify the cache initialization settings that the Addressables system should use:
|
|
|
|
1. Create the CacheInitializationSettings asset (menu: __Assets > Addressables > Initialization > Cache Initialization Settings__).
|
|
2. Select the new asset file in the Project panel to view the settings in the Inspector

|
|
|
|
3. Adjust the settings as desired.
|
|
4. Open the Addressables Settings Inspector (menu: __Window > Asset Management > Addressables > Settings__).
|
|
5. In the __Initialization Objects__ section of the Inspector, click the __+__ button to add a new object to the list.
|
|
6. Select your CacheInitializationSettings asset in the File dialog and click __Open__.
|
|
7. The cache settings object is added to the list.
|
|

|
|
|
|
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.
|
|
|
|
> [!NOTE]
|
|
> Android applications built with Unity 202.1 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.
