显示UnityWebRequest的进度

问题描述

我正在尝试使用 Unity Web请求并显示进度，根据我需要捕获的文档一个WebRequestAsyncOperation对象来查找进度，但是我找不到它

I'm trying to download an assetbundle using Unity Web Request and show the progress, according to the documentation i need to capture a WebRequestAsyncOperation object to find the progress but i cannot find it

我尝试使用AsyncOperation和UnityWebRequestAsyncOperation，并且我的例程可以同时使用，使用一个或另一个有什么区别?

I tried using AsyncOperation and UnityWebRequestAsyncOperation and my routine works with both, what is the difference of using one or another?

这是我的代码:

IEnumerator DownloadModel3D()
    {
        using (UnityWebRequest uwr = UnityWebRequest.GetAssetBundle(bundleURL,1,0))
        {
            //UnityWebRequestAsyncOperation request = uwr.SendWebRequest();
            AsyncOperation request = uwr.SendWebRequest();

            while (!request.isDone)
            {
                Debug.Log(request.progress);
                yield return null;
            }


            if (uwr.isNetworkError || uwr.isHttpError)
            {
                Debug.Log(uwr.error);
            }
            else
            {
                // Get downloaded asset bundle
                AssetBundle bundle = DownloadHandlerAssetBundle.GetContent(uwr);

                assetBundleInstance = Instantiate(bundle.LoadAsset(assetName)) as GameObject;
                assetBundleInstance.transform.position = transform.position;
                assetBundleInstance.transform.localScale = new Vector3(.08f, .08f, .08f);
                assetBundleInstance.transform.SetParent(transform);
                contador.text = "Descargado: " + assetName + "\n" + bundleURL;
            }
        }
    }

推荐答案

如果您的意思是 WebRequestAsyncOperation 与 UnityWebRequestAsyncOperation 不同，那么事实就是如此.

If you mean that WebRequestAsyncOperation is not the same as UnityWebRequestAsyncOperation, turns out they are.

UnityWebRequestAsyncOperation

从 UnityWebRequest .SendWebRequest()返回的异步操作对象."

"Asynchronous operation object returned from UnityWebRequest.SendWebRequest()."

您已经在使用哪种方法.

Which is the method you already are using.

来源: https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequestAsyncOperation .html

UnityWebRequestAsyncOperation继承自AsyncOperation，这意味着它们共享相同的字段，并且可能也共享相同的方法.尽管如此，UnityWebRequestAsyncOperation仍具有以下字段:

UnityWebRequestAsyncOperation inherits from AsyncOperation, meaning they share the same fields and likely also same methods. UnityWebRequestAsyncOperation additionally has the field below though:

webRequest返回创建操作的关联UnityWebRequest.

webRequest Returns the associated UnityWebRequest that created the operation.

如果这不能回答您的问题，请详细说明.

If this didn't answer your question please elaborate.
