Unity Networking API Public functions

so im lost on how to call the functions in the unity NetWorkLobbyManager i found this by peeking into the code

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
public class NetWorkLobbyManager : NetworkLobbyManager 
{ 
public virtual void OnLobbyClientEnter() 
    { 
      Debug.Log("A player has joined the lobby");
    }
 }

but since it dosent do anything im pretty much lost on how to call the Networking OnSomething Functions any help is greatly apreciated

found this while looking at random questions :smiley:
public override void OnLobbyClientEnter()
{
StartScreen.gameObject.SetActive(false);
lobbyPlayerParrent.gameObject.SetActive(true);
}
apparently i have to use Override instead of virtual
