LoadFormFileAssetBundle

1.构建AssetBundle

构建脚本路径：Editor/BuildAssetBundles

先给需要打包的资源指定 AssetBundle 标签
然后点击菜单栏 Assets/Build AssetBundles 构建打包

2.加载AssetBundle资源

1) 加载本地资源

// 从文件读取
AssetBundle ab = AssetBundle.LoadFromFile(Path);
// 异步(需要协程)
// AssetBundleCreateRequest abRequest = AssetBundle.LoadFromFileAsync(objPath);
// yield return abRequest;
// AssetBundle ab = abRequest.assetBundle;


// 从内存读取
AssetBundle ab = AssetBundle.LoadFromMemory(File.ReadAllBytes(Path));
// 异步同上
// AssetBundle ab = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(Path));
// .....

2) 加载远程资源

需要先把打包好的AssetBundle文件放在webSereve目录下，然后启动webSereve服务器。

void Start()
{
    // 开启协程
    StartCoroutine(GetAssetBundle());
}

IEnumerator GetAssetBundle()
{
    string uri = @"http://localhost/AssetBundles/obj.lcl";
    UnityWebRequest www = UnityWebRequestAssetBundle.GetAssetBundle(uri);
    yield return www.SendWebRequest();
    if (www.isNetworkError || www.isHttpError)
    {
        Debug.Log(www.error);
    }
    else
    {
        AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(www);
        GameObject prefab = bundle.LoadAsset<GameObject>("assetBundle_Cube");
        Instantiate(prefab);
    }
}

3.卸载AssetBundle

ab.Unload(false);
ab.Unload(true);
