Unity3D UnityWebRequest获取AssetBundle包

由于Unity Manual文档的UnityWebRequest相关api未更新，相关方法已经弃用。特写此博客记录最新的使用方法。

       

旧的方法

    IEnumerator InstantiateObject() {
        string uri = "file:///" + Application.dataPath + "/AssetBundles/" + assetBundleName;
        UnityEngine.Networking.UnityWebRequest request = UnityEngine.Networking.UnityWebRequest.GetAssetBundle(uri, 0);
        yield return request.Send();
        AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request);
        GameObject cube = bundle.LoadAsset("Cube");
        GameObject sprite = bundle.LoadAsset("Sprite");
        Instantiate(cube); Instantiate(sprite);

    }

 

//新的加载AB的方式：

IEnumerator InstantiateObject() {
        string path = @"http://localhost/AssetBundle/rock.zl";
        UnityWebRequest request = UnityWebRequest.Get(path);
        yield return request.SendWebRequest();
        while (request.isHttpError)
        {
            Debug.LogError(TAG+"ERROR"+request.error);
            yield return null;
        }
        while (!request.isDone)
        {
            yield return null;
        }
        byte[] results = request.downloadHandler.data;
        AssetBundle ab = AssetBundle.LoadFromMemory(results);

        //实例化
        GameObject obj = ab.LoadAsset("Rock");
        Instantiate(obj);

}
