Method UpdateCatalogs

UpdateCatalogs(IEnumerable<string>, bool)

Update the specified catalogs.

선언

public static AsyncOperationHandle<List<IResourceLocator>> UpdateCatalogs(IEnumerable<string> catalogs = null, bool autoReleaseHandle = true)

파라미터

타입	이름	설명
IEnumerable<string>	catalogs	The set of catalogs to update. If null, all catalogs that have an available update will be updated.
bool	autoReleaseHandle	If true, the handle will automatically be released when the operation completes.

AsyncOperationHandle<List<IResourceLocator>>	The operation with the list of updated content catalog data.

참고

When you call the UpdateCatalog function, all other Addressable requests are blocked until the operation is finished. You can release the operation handle returned by UpdateCatalogs immediately after the operation finishes (or set the autoRelease parameter to true).

If you call UpdateCatalog without providing a list of catalogs, the Addressables system checks all of the currently loaded catalogs for updates.

If you update a catalog when you have already loaded content from the related AssetBundles, you can encounter conflicts between the loaded AssetBundles and the updated versions. To avoid conflicts, update the catalog before loading assets or unload the AssetBundles before the updating the catalog. You can enable the Unique Bundle Ids option in your Addressable settings to avoid conflicts, but that can increase memory consumption since you will still have the original AssetBundles in memory after loading the updated ones. Enabling this option can also make the download size of content updates larger because typically more AssetBundles must be rebuilt.

You can call UpdateCatalogs(bool, IEnumerable<string>, bool) with the first value set to true to automtically remove any nonreferenced bundles from the cache after updating the catalogs.

예

In this example all catalogs are checked for updates:

IEnumerator CheckCatalogs()
{
    List<string> catalogsToUpdate = new List<string>();
    AsyncOperationHandle<List<string>> checkForUpdateHandle
        = Addressables.CheckForCatalogUpdates();
    checkForUpdateHandle.Completed += op => { catalogsToUpdate.AddRange(op.Result); };

    yield return checkForUpdateHandle;

    if (catalogsToUpdate.Count > 0)
    {
        AsyncOperationHandle<List<IResourceLocator>> updateHandle
            = Addressables.UpdateCatalogs(catalogsToUpdate);
        yield return updateHandle;
        Addressables.Release(updateHandle);
    }

    Addressables.Release(checkForUpdateHandle);
}

Alternatively you can directly get a list of catalogs and perform the updates:

IEnumerator CheckCatalogs()
{
    List<string> catalogsToUpdate = new List<string>();
    AsyncOperationHandle<List<string>> checkForUpdateHandle
        = Addressables.CheckForCatalogUpdates();
    checkForUpdateHandle.Completed += op => { catalogsToUpdate.AddRange(op.Result); };

    yield return checkForUpdateHandle;

    if (catalogsToUpdate.Count > 0)
    {
        AsyncOperationHandle<List<IResourceLocator>> updateHandle
            = Addressables.UpdateCatalogs(catalogsToUpdate);
        yield return updateHandle;
        Addressables.Release(updateHandle);
    }

    Addressables.Release(checkForUpdateHandle);
}
