UnityWebRequest editor script

Hello everybody,
I tried to use the new UnityWebRequest class in an editor script.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEditor;
4. using UnityEngine.Experimental.Networking;
5.  
6. public class UnityWebRequestWindow:EditorWindow{
7.  
8.     [MenuItem ("Window/UnityWebRequest")]
9.     public static void  ShowWindow () {
10.         EditorWindow.GetWindow(typeof(UnityWebRequestWindow));
11.     }
12.     void OnGUI () {
13.         if (GUILayout.Button ("New Web request")) {
14.             UnityWebRequest uwr = UnityWebRequest.Get("http://www.unity3d.com");
15.             uwr.Send ();
16.             while (!uwr.isDone) {
17.             }
18.             if (uwr.isError) {
19.                 Debug.Log ("Error");
20.             }
21.             Debug.Log ("uwr.downloadHandler.text");
22.             uwr.Dispose ();
23.         }
24.     }
25. }
26.  

I found that CPU usage raises incrementally at every request!!
if i switch to play mode, this problem disappear.
There is something wrong in my script or it is a bug?

Thanks in advance

 

The issue has been reproduced by Unity. Please don't hesitate to vote it:

Could be the busy wait consume all the cpu time? Try this instead,

        while (!request.isDone)

            Thread.Sleep(50);

 

That will block the main thread as well.

In theory you should start a coroutine and use yields instead.
But coroutines in editor should be updated manually via something like Editor.update callback as they do not work properly as in runtime.

Also, do not necro ancient threads.
