AssetBundle

描述

API for accessing the content of AssetBundle files.

This class exposes an API, via static methods, for loading and managing AssetBundles.

This same class offers non-static methods and properties that expose the contents of a specific loaded AssetBundle, including the ability to load an Asset from within an AssetBundle.

Create AssetBundles by calling BuildPipeline.BuildAssetBundles or using the Addressables package. The build process generates one or more AssetBundle files, and each AssetBundle file contains a serialized instance of this class.

Note: AssetBundle.LoadAsset, and the other Load methods, do not support loading Scenes from AssetBundles. Instead, in runtime you load the streamed scene AssetBundle and then call SceneManager.LoadScene or SceneManager.LoadSceneAsync with the Scene name. In the Editor it is not supported to load Scenes from AssetBundles so calls to EditorSceneManager.OpenScene will fail with an error that the Scene file is not found.
