Namespace UnityEngine.ResourceManagement.ResourceProviders

Classes

AssetBundleProvider

IResourceProvider for asset bundles. Loads bundles via UnityWebRequestAssetBundle API if the internalId starts with "http". If not, it will load the bundle via AssetBundle.LoadFromFileAsync.

WARNING: Direct bundle loading using this provider is NOT RECOMMENDED for most applications. Use Addressables.LoadAssetAsync<T>() to load individual assets instead, which provides automatic dependency resolution and better error handling.

This provider is for advanced scenarios only where manual bundle management is required.

AssetBundleRequestOptions

Contains cache information to be used by the AssetBundleProvider

AssetBundleResource

Provides methods for loading an AssetBundle from a local or remote location.

AssetDatabaseProvider

Provides assets loaded via the AssetDatabase API. This provider is only available in the editor and is used for fast iteration or to simulate asset bundles when in play mode.

AtlasSpriteProvider

Provides sprites from atlases

BinaryCatalogInitialization

Object used to specify custom values for the cache sizes used in Binary Catalogs.

BinaryDataProvider

Provides raw text from a local or remote URL.

BundledAssetProvider

Provides assets stored in an asset bundle.

CachedFileProvider

Downloads remote files to a local cache and returns the path. This path can be used to load the data with other providers such as BinaryDataProvider.

ContentDirectoryAssetData

Data stored in ContentCatalogDataEntry.Data for asset entries in Content Directories.

ContentDirectoryMountManager

Mounts Content Directories on demand and shares a single mount across every asset and scene that loads from the same load path. Replaces the previous design where a dedicated ContentDirectoryProvider loaded the directory as a shared dependency.

A directory is mounted at most once (the first EnsureMounted(string) for a resolved path calls ContentLoadManager.RegisterContentDirectory) and then stays mounted for the lifetime of the Addressables system. All mounts are released together by UnmountAll(), which is called from AddressablesImpl.Dispose. All access is expected on the main thread.

InstanceProvider

Basic implementation of IInstanceProvider.

JsonAssetProvider

Converts JSON serialized text into the requested object.

ProviderLoadRequestOptions

Contains options used in Resource Provider load requests. ProviderLoadRequestOptions are used to specify parameters such as whether or not to ignore load failures and UnityWebRequest timeouts.

ProviderLoadRequestOptions.SerializationAdatapter

Provides serialization and deserialization support for ProviderLoadRequestOptions objects using the BinaryStorageBuffer format.

ResourceLocationUtil

Utility class for working with resource locations in the Resource Manager.

ResourceProviderBase

Base class for IResourceProvider.

TextDataProvider

Provides raw text from a local or remote URL.

Structs

InstantiationParameters

Class that contains properties to apply to instantiated objects.

ProvideHandle

Container for all data need by providers to fulfill requests.

SceneInstance

Wrapper for scenes. This is used to allow access to the AsyncOperation and delayed activation.

Interfaces

IAddressableRootAsset

Implemented by the global root asset embedded in a Content Directory. Exposes the scene id lookup needed by SceneProvider without depending on the concrete root asset type (which lives in the higher-level Addressables assembly).

IAssetBundleResource

Wrapper for asset bundles.

WARNING: Loading bundles directly using LoadAssetAsync<IAssetBundleResource>() is NOT RECOMMENDED for most use cases as it bypasses automatic dependency resolution and can cause serialization issues with ScriptableObjects.

RECOMMENDED: Use LoadAssetAsync<T>() to load individual assets instead, which provides automatic dependency handling and better error resilience.
