Joining an In-Progress Game

To join an in-progress game

1. After creating a NetworkSession, set AllowJoinInProgress to true.

   int maximumGamers = 8;  
   int privateGamerSlots = 2;
   int maximumLocalPlayers = 1;
   
   // Create the session
   session = NetworkSession.Create( 
       NetworkSessionType.SystemLink,
       maximumLocalPlayers, maximumGamers, privateGamerSlots, 
       sessionProperties );
   
   session.AllowJoinInProgress = true;
   

   In the NetworkSession.GamerJoined event handler, the gamer may be a player who joined an in-progress game.

2. Associate any data necessary to enable a gamer to join while the game is in-progress.

   void session_GamerJoined(object sender, GamerJoinedEventArgs e)
   {
       // Associate a tank object with this gamer.
       e.Gamer.Tag = 
           new Tank(Content, GraphicsDevice.PresentationParameters);
   
   }
