关于unity2019 AssetBundle UnityWebRequest的使用

官方文档给出的是这样的

    IEnumerator InstantiateObject()
    {
        string uri = "file:///" + Application.dataPath + "/AssetBundles/" + assetBundleName;//ab包路径
        UnityEngine.Networking.UnityWebRequest request = UnityEngine.Networking.UnityWebRequest.GetAssetBundle(uri, 0);//获取UnityWebRequest
        yield return request.Send();//等待获取完成 
        AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request);//再获取到ab包
        GameObject cube = bundle.LoadAsset<GameObject>("Cube");
        GameObject sprite = bundle.LoadAsset<GameObject>("Sprite");
        Instantiate(cube);
        Instantiate(sprite);
    }

这段代码在unity2017里是没什么问题的，但在unity2019有些api改掉了，直接复制粘贴会报错 

 

 

 

 

 

 

 

 

 改成这样就 可以了

    IEnumerator DownloaAssetBundle(string name)
    {
        string uri = @"http://localhost/AssetBundles/" + name;//ab包路径
        UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(uri);//获取UnityWebReuest
        yield return request.SendWebRequest();//等待获取完成 
        AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(request);//获取ab包
        GameObject cube = bundle.LoadAsset<GameObject>("Cube");
        GameObject sprite = bundle.LoadAsset<GameObject>("Sprite");
        Instantiate(cube);
        Instantiate(sprite);
    }
