polling a www url?

Hi

I hope someone can help me. Since my provider doesn't offer websockets like node.js I can only poll my php scripts from the server to check if a value in my database has changed. Since I need the update only ever 5 oder 10 minutes it shouldn't be a big problem but I don't know how to implement the polling in Unity. I made a gameobject with my script:

Code (csharp):

1.  
2. public class Polling : MonoBehaviour {
3.  
4.   Thread WorkerThread;
5.   bool m_bEnd = false;
6.    
7.    
8.   void Start () {
9.   WorkerThread = new Thread(new ThreadStart(PollData));
10.   WorkerThread.Start();
11.  
12.   }  
13.    
14.  
15.   void PollData()
16.   {
17.   while (m_bEnd == false)
18.   {
19.   StartCoroutine(GetDataFromServer());
20.   Thread.Sleep(600000); // poll Server only after 10 min
21.   }
22.    
23.   }
24.  
25.  
26.   private IEnumerator GetDataFromServer()
27.   {
28.   string strUrl;
29.   WWW www;
30.    
31.    
32.   strUrl = "http://www.myserver.de/myscript.php";
33.  
34.    
35.   www = new WWW(strUrl); //GET data is sent via the URL
36.  
37.   while (!www.isDone && string.IsNullOrEmpty(www.error))
38.   {
39.   yield return null;
40.   }
41.  
42.          // Do something with the results
43.   // ...
44.  
45.   }
46.  
47.   void OnApplicationQuit()
48.   {
49.   m_bEnd = true;
50.   }
51.  
52.  
53. }
54.  

Well when I added some debug logs then I could see the thread is sleeping for 10 minutes and then he woke up like I expected it. But when I added the www request I can see that the request is never called. I guess the reason is that the thread goes to sleep after calling the coroutine but I don't know what other way I could implement a polling

 

have you taken a look at InvokeRepeating? all you need to pass is the method name and to floats for the timers

 

Thank you this solved my problem
