Unity中使用UnityWebRequest加载AssetBundle

1.使用UnityWebRequest需要引用using UnityEngine.Networking.

2.UnityWebRequest中有几个方法，UnityWebRequest.GetAssetBundle（URL）获取assetBundle资源，有一个返回资源的函数SendWebRequest，用来下载资源，DownloadHandlerAssetBundle.GetContent()未获取assetBundle资源包，接着就是LoadAsset<>()加载，实例化。

3.代码如下

void Start () {

StartCoroutine(Load());

}

private IEnumerator Load()
{
string url = "";//此为AssetBundle资源路径，可为本地，也可以是服务端
UnityWebRequest request=  UnityWebRequest.GetAssetBundle(url);
yield return request.SendWebRequest ();
// AssetBundle ab = DownloadHandlerAssetBundle.GetContent (request );

AssetBundle ab = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;
GameObject ao = ab.LoadAsset<GameObject>("Man1");
Instantiate(ao);
}

4.多看看UnityApi。
