How to Ping specific an address

Hi, this is my first post in this forum, I´m not a native speaker, so, excuse me if I make some mistakes or misspelled words.
I've been trying to do a ping to an specific address, but I couldn't make it. I tried to find a previous post about this topic, but I couldn't find it. I really will appreciate for any help.

Code (CSharp):

1.  
2. public string direccion;
3.  
4. void Update () {
5.      Ping pinger = new Ping (direccion);
6.      tiempo= pinger.time;
7.   print(""+tiempo);
8.        
9.    }
10.  

Note: I know, that the string is a IP address, I´m testing using 216.58.192.100, a google address.

 

you probably don't want that code in an update, you'll be creating a new ping every frame!

from the api scripting page (http://docs.unity3d.com/ScriptReference/Ping.html) the ping is "asynchronous" i.e. it starts doing "it's thing" when you create it, but it might not be done and able to return a time until a little while later.

So you want to create 1 ping object (just one, not one per frame!), then check the "isDone" (http://docs.unity3d.com/ScriptReference/Ping-isDone.html) to see if it has come back with a time yet.

 

Actually I don´t want to do a ping each frame, this code is just for a test, The idea is to create a button to test the delay between server and client. I´m already check for the documentation you linked(thanks by the way), but the issue is to know why when run the code, the result is just "-1", and the isDone "false".

Note:I tried the same code in the start function, I just copied the last code I tried.

 

the ping isn't going to have a value immediately in the same frame. Create the ping, check for isDone in update, when isDone is true access the time.

 

Try something like this?

Code (CSharp):

1. public void CheckPing(string ip)
2.         {
3.             StartCoroutine(StartPing(ip));
4.         }
5.  
6.         IEnumerator StartPing(string  ip)
7.         {
8.             WaitForSeconds f = new WaitForSeconds(0.05f);
9.             Ping p = new Ping(ip);
10.             while (p.isDone == false)
11.             {
12.                 yield return f;
13.             }
14.             PingFinished(p);
15.         }
16.  
17.  
18.         public void PingFinished(Ping p)
19.         {
20.             // stuff when the Ping p has finshed....
21.         }

Call CheckPing once and wait for pingfinished to be called

 

Thanks, that was de problem, I was thinking in use the IEnumarator, But actually I didnt do it.
Solved.
