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() );
}
}
