AssetEntryBase<T0>

Description

Serves as the base class for asset entries that own a stored reference and load and release the asset themselves.

The type parameter is the stored reference the entry keeps in AssetEntryBase<T0>.Default, and each concrete kind decides how that reference resolves to an asset: AssetEntry stores a direct object, and ResourceAssetEntry stores a Resources path. The built-in kinds are synchronous: they resolve through ISynchronousAssetEntry.TryLoadAsset, and public callers use the IAssetEntry members AssetEntryBase<T0>.HasAsset and AssetEntryBase<T0>.ReleaseAsset. To add a custom kind, override the protected HasValue, TryLoadSync, and Release members to back a different storage, such as an Addressables handle provided by a package.

Additional resources: AssetEntry, ResourceAssetEntry, IAssetEntry, ResourceTable
