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, once a streamed scene AssetBundle has been loaded you can call SceneManager.LoadScene or SceneManager.LoadSceneAsync.

See Also: Intro to AssetBundles, UnityWebRequestAssetBundle.GetAssetBundle, BuildPipeline.BuildAssetBundles.

using UnityEngine.Networking;

public class SampleBehaviour : MonoBehaviour { IEnumerator Start() { var uwr = UnityWebRequestAssetBundle.GetAssetBundle("https://myserver/myBundle.unity3d"); yield return uwr.SendWebRequest();

// Get an asset from the bundle and instantiate it. AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(uwr); var loadAsset = bundle.LoadAssetAsync<GameObject>("Assets/Players/MainPlayer.prefab"); yield return loadAsset;

Instantiate(loadAsset.asset); } }
