Forum ‹ ActionScript 3.0 ‹ Double-blind turn based game

[AniMoney]

My goal is to make a double-blind game, one where both players make their decisions privately and then they are both revealed simultaneously. A simple example would be rock-paper-scissors, a more complicated example would be Kongai on Kongregrate.

I somewhat understand how to a regular turn based game, where one player goes and then the other. I looked through the tic-tac-toe example to try to understand it. I got the gist of it but wish it was better commented, especially since I'm new to C#.

Could anyone help me out in how to set this up? If someone has a rock-papers-scissors example or something that'd be even better.

That's an cool idea!

My guess of coding this would be like:
1) Client A & B should tell the server which actions are being executed via a message using connection.Send("EventMessageTypeName", properties);
2) when server received both events from both the clients A & B, then only send a new event to both client to execute the events.

Of course depending on what game your turn based game idea is, it can change a lot with the code. This is somewhat a basic idea for your double-blind turn based game.


For tic-tac-toe it would be:
1) Client A sends a move via a message to the server.
2) Server receives message from client A and send this message to Client B.
3) Client B receive the message from the server and execute the action.
4) Client B can set it's turn and repeat from step 1, until someone wins or the game has ended to a draw.


I don't have a lot of spare time these days, because of my own projects, so I can't help you a lot with some useful code.

I'm still having trouble getting it working, I'm trying to edit the Tic-Tac-Toe project to make it a double-blind game instead, but I'm not very familiar with using MonoDevelop.

I'm having a problem. I'm working on a mac using Xamarin (similar to monodevelop), and when I'm on the development server I get this problem. I will have one player create a room in the lobby, but my serverside code will initialize the player twice for some reason.

here is the relevant snippet from my serverside code, it's modified straight from the code in the tic tac toe example:

Code: Select all

      private void joinGame(Player user)
      {
         if(player1 == null)
         {
            Console.WriteLine ("There is no player1, so initializing a client as player 1.");
            user.Send("init", 0, user.ConnectUserId);
            player1 = user;
         }
         else if(player2 == null)
         {
            Console.WriteLine ("There is no player2, so initializing a client as player 2.");
            user.Send("init", 1, user.ConnectUserId);
            player2 = user;
         }
         else
         {
            Console.WriteLine ("Both players already exist, so adding client as spectator.");
            //Send current game state to spectators
            user.Send("spectator", player1.ConnectUserId, player2.ConnectUserId);
            return;
         }

         if(player1 != null && player2 != null)
         {
            Broadcast("join", player1.ConnectUserId, player2.ConnectUserId);
            user.Send("join", player1.ConnectUserId, player2.ConnectUserId);
            resetGame(user);
         }
      }

So I'll build and run the server, then open up my .swf (just one copy!) and create a room, and I'll get this output in my server

[01:57:34 in 'hxfmdcrpaku5mRUu3bn5gg'] => There is no player1, so initializing a client as player 1.
[01:57:34 in 'hxfmdcrpaku5mRUu3bn5gg'] => There is no player2, so initializing a client as player 2.

I don't get why this is happening. There is only one client connected but it seems to be calling the joinGame function twice? However when I uploaded the .dll to player.io and ran it off their server I didn't get this problem. I'm really getting fed up with Xamarin/MonoDevelop.

Also I get this error in my console, but then it seems to run fine after. Do I need to use a different version of mono or open some ports or something? I've done some as3 programming before but I'm brand new to networking and I'm pretty lost with these errors. Any help is greatly appreciated.

That's a file system permission error. You, or the user MonoDevelop is running as, doesn't have permissions to create that directory.

I am on a MacBook Pro and I am the only user account, and therefore the admin, so it shouldn't be an admin privileges issue. I'm still getting that output in my console but it seems to be working anyways? I've sort of fixed the problem of it initializing one client twice by deleting the old .dll and updating the assembly settings. It works most of the time now, but still once in a while it will add one client as player 1 and 2. I really don't know why, perhaps it's registering two clicks on the create room button in the .swf or something, I'm stumped.
