Connecting to a server

To connect to a server you know the IP address of, you can call Network.Connect.

The following script allows the player to enter an IP, a port, and an optional password and attempts to connect to the server:

using UnityEngine;
using System.Collections;

public class ExampleUnityNetworkingConnectToServer : MonoBehavior
{
  private string ip = "";
  private string port = "";
  private string password = "";

  void OnGUI()
  {
    GUILayout.Label( "IP Address" );
    ip = GUILayout.TextField( ip, GUILayout.Width( 200f ) );

    GUILayout.Label( "Port" );
    port = GUILayout.TextField( port, GUILayout.Width( 50f ) );

    GUILayout.Label( "Password (optional)" );
    password = GUILayout.PasswordField( password, '*',GUILayout.Width( 200f ) );

    if( GUILayout.Button( "Connect" ) )
    {
      int portNum = 25005;

      // failed to parse port number – a more ideal solution is tolimit input to numbers only, a number of examples can befound on the Unity forums
      if( !int.TryParse( port, out portNum ) )
      {
        Debug.LogWarning( "Given port is not a number" );
      }
      // try to initiate a direct connection to the server
      else
      {
        Network.Connect( ip, portNum, password );
      }
    }
  }

  void OnConnectedToServer()
  {
    Debug.Log( "Connected to server!" );
  }

  void OnFailedToConnect( NetworkConnectionError error )
  {
    Debug.Log( "Failed to connect to server: " +error.ToString() );
  }

}
