i really dont know how to script so if someone can help me with this script i would be really grateful

I got a button that start a server but is probbably not correct

if (GUI.Button (Rect (25, 80, 100, 30), "Start Server"))
{
Network.InitializeServer(32, 25002, !Network.HavePublicAddress());
MasterServer.RegisterHost("MyUniqueGameType", "NetworkName", "l33t game for all");
}

And i got the Connect button

if (GUI.Button (Rect (25, 160, 100, 30), "Connect")) {

This is the bit i dont know how to do. how can i check if there is a server started?
Thanks in advance

Networking Guide

Check the Master server tutorial in there. The master server is made by Unity, and displays servers to the users.

Ok thanks
