Network server for a turn-based strategy game

0 posts in this topic

Hello Gamedev'ers,

I recently started coding a simple multiplayer turn-based strategy game.
My tools of choice (for now) are C#, XNA for Windows, Lidgren Network and MSSQL.

Now, I haven't done any multiplayer stuff since experimenting with DirectPlay last millenium,
so I sat down and drew some pseudocode how I imagine the game server would work.

I'm starting coding it right now, and it would be of great value to me if you wanted to look at my pseudocode, to see if something is horribly wrong or give general feedback.

Thank you in advance.

Best regards,
Daniel Molnar

Pseudocode for the GameServer application below:


enum GameServerStates
Error = 0,

enum DataMessageTypes
Error = 0,

//// the main GameServer class
class GameServer
start Lidgren server with DAL.LoadConfiguration();

Loop forever:

for each incoming message
read [GameId] from Message and send it to the specific game instance

for each active Game instance
//do special and timed events for all active games

if (Game.ServerState == GameOver)



//// one class instance per active game
int myGameId;
GameServerStates myGameServerState;
List<Player> ConnectedClients;

case DataMessageType.MovementUpdate:
//do movement update server logic
//send relevant messages back to all clients

case etc etc (do relevant server updates for each DataMessageType)

////connects to a MS SQL Server with LINQ

//Server configuration, ip address, port, etc. is read from the database

//when a game is finished/paused/cancelled, the details are flushed to the database: game id, players, result, etc.

//Bring back a saved/unfinished game from the db

//read statistics (high-score lists, etc.) from db

//simplest possible login: username and password (password only needed if you want to "register" your username)
