Unity用WWW下载PNG格式后赋值给RawImage发虚问题解决！

unity版本2019.4.9。问题：项目中用Unity的WWW下载PNG图片，赋值给RawImage后，出现图片模糊、发虚问题（编辑器模式下无问题，打包后出现问题）。

问题的下载PNG图代码：

    private IEnumerator onDownLoadTexture(string path, RawImage raw){WWW www = new WWW(path);yield return www;if (www.isDone){Texture2D texture = www.texture;texture.filterMode = FilterMode.Trilinear;texture.Apply();raw.texture = texture;}}

修改后的代码：

 private IEnumerator onDownLoadTexture(string path, RawImage raw){UnityWebRequest wr = new UnityWebRequest(path);DownloadHandlerTexture texDl = new DownloadHandlerTexture(true);wr.downloadHandler = texDl;yield return wr.SendWebRequest();if (!(wr.isNetworkError || wr.isHttpError)){Texture2D t = texDl.texture;t.filterMode = FilterMode.Trilinear;t.Apply();raw.texture = t;}}

发虚问题解决！
