關於unity2019 AssetBundle UnityWebRequest的使用

官方文檔給出的是這樣的

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

這段代碼在unity2017里是沒什么問題的，但在unity2019有些api改掉了，直接復制粘貼會報錯 

 

 

 

 

 

 

 

 

 改成這樣就 可以了

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