Implementing the client

With the class definition covered, it's time to actually make it do something, starting with the constructor and destructor:

Client::Client():m_listenThread(&Client::Listen, this){}
Client::~Client(){ m_socket.unbind(); }

In the client constructor's initializer list, we bind the listening thread to the Listen method of this class. Threads do not have a default empty constructor, which is why this is necessary. The destructor is simply used to unbind the socket we're using.

Now, let's take a stab at implementing the connection protocol:

bool Client::Connect(){
  if (m_connected){ return false; }
  m_socket.bind(sf::Socket::AnyPort);
  sf::Packet p;
  StampPacket(PacketType::Connect, p);
  p << m_playerName;
  if (m_socket.send(p, m_serverIp, m_serverPort) !=
    sf::Socket::Done)
  {
    m_socket.unbind();
    return false;
  }
  m_socket.setBlocking(false);
  p.clear();
  sf::IpAddress recvIP;
  PortNumber recvPORT;
  sf::Clock timer;
