Integración utilizando el NetworkTransport

Si usted necesita la mayor cantidad de flexibilidad cuando integre Unity Multiplayer Services, usted puede utilizar la clase NetworkTransport directamente. Este método requiere más código, pero le permite a usted controlar cada detalle de cómo su juego se integra con los Multiplayer Services.

Este es un ejemplo de cómo conectarse directamente utilizando la clase NetworkTransport:

using UnityEngine;
using UnityEngine.Networking;
using UnityEngine.Networking.Types;
using UnityEngine.Networking.Match;
using System.Collections.Generic;

public class DirectSetup : MonoBehaviour
{
    // Matchmaker related
    List<MatchInfoSnapshot> m_MatchList = new List<MatchInfoSnapshot>();

    bool m_MatchJoined;

    string m_MatchName = "NewRoom";
    NetworkMatch m_NetworkMatch;

    // Connection/communication related
    int m_HostId = -1;
    // On the server there will be multiple connections, on the client this will only contain one ID
    List<int> m_ConnectionIds = new List<int>();
    byte[] m_ReceiveBuffer;
