Jetserver is a high speed nio socket based multiplayer java game server written using Netty and Mike Rettig's Jetlang.It is specifically tuned for network based multiplayer games and supports TCP and UDP network protocols.

Overview

Note New version of Jetserver is called Nadron and is in a new netty 4 branch of this same repo.
JetServer is a java nio based server specifically designed for mutliplayer games. It supports UDP and TCP transports. It uses Netty for high speed network transmission and Jetlang for extremely fast in-vm message passing between player sessions and game rooms. The project also uses spring for its dependency injection. This way, it is highly configurable and you can swap out any part of the server with your own implementations.

Wiki

The wiki provides implementation level details and answers to general questions that a developer starting to use jetserver might have about it. The following blog has post on game creation.

Support Group

For general discussion please use the jetserver google group. Issues and bugs can be raised directly in github.

Installation

Maven

<dependency>
    <groupId>com.github.menacher</groupId>
    <artifactId>nadron</artifactId>
    <version>0.5</version>
</dependency>

From Source

Using pre-built jar files

The pre-built jar files of this project are located in the jetserver/binaries directory. All dependent jars are located in the jetserver/lib directory. You can add them to your favorite IDE’s classpath for coding. If you want to compile from source, then follow steps below.

With Maven and using Eclipse

Pre-requisites: Please have maven 3+ and Spring source tool suite or eclipse installed. If you are using plain vanilla eclipse, then M2Eclipse and EGit plugins though not required will be helpful. The maven-eclipse plugin part of pom.xml should be modified when using another IDE.

Steps

  1. git clone [email protected]:menacher/java-game-server.git
  2. cd java-game-server
  3. cd jetserver
  4. mvn eclipse:eclipse - Takes time, the first time! If you want to reduce this time, then comment out include sources/jars option from the maven pom.xml eclipse plugin part.
  5. eclipse -> file -> import -> git -> select repository and import jetserver project.
  6. jetserver project in eclipse -> right click on pom.xml -> run as -> maven test - Takes time the first time!

If everything works as expected you should see some test cases executed successfully!

With Ant

If you are using ant, then the lib folder within the jetserver project contains all the dependent libraries. Just right click and run ant build and it will create the jetserver jar.

Happy coding!

  • Refactor

    Refactor "I" from interface names

    The leading letter "I" in interfaces is really annoying when you program against interfaces, which you almost always do, when dealing with Spring Framework powered applications. I'm evaluating JetServer as a core for a game I'm planning to develop, but I'll have to fork it and refactor each I[InterfaceName] to [InterfaceName] myself and then sync changes from the original project every time a bug is fixed or an interesting feature is added. This isn't a deal-breaker of course, but a nuisance I'm not looking forward to :( I do understand that such kind of change would break the API, and I also understand that prepending or not interface names with a letter "I" is a bit holywar-ish, but I just had to try :)

  • accept or reject an user at server side

    accept or reject an user at server side

    Hello again,

    I am back to implement authentication of client at server. At client side I use this code

    Where userId, accessToken, firstName and lastName come from Facebook authentication of the client. So then client provides this data to server who will check validity of the data and then accept or the reject the user.

    public static void connect (String userId, String accessToken, String firstName, String lastName) {
            //disable previous listener
            if (future != null) {
                future.cancel();
                future.removeListener(futureListener);
            }
    
            //connect to server
            future = bootstrap.connect(new InetSocketAddress(host, port));
    
            final ChannelBuffer loginBuffer = getLoginBuffer("CONNECT_ROOM_REF_KEY", userId, accessToken, firstName, lastName);
            futureListener = new ChannelFutureListener() {
                @Override
                public void operationComplete(ChannelFuture future) throws Exception
                {
                    Channel channel = future.getChannel();
                    channel.write(loginBuffer);
                }
            };
    
            future.addListener(futureListener);
        }
    
        private static ChannelBuffer getLoginBuffer(String refKey, String userId, String accessToken, String firstName, String lastName) {
            //1 stands for capacity - number of bytes, big Endian
            ChannelBuffer opCode = ChannelBuffers.buffer(1);
    
            opCode.writeByte(Events.LOG_IN);
            //Creates a new composite buffer which wraps the readable bytes of the specified buffers without copying them. A modification on the content of the specified buffers will be visible to the returned buffer.
            ChannelBuffer buffer = ChannelBuffers.wrappedBuffer(opCode, NettyUtils.writeStrings(refKey, userId, accessToken, firstName, lastName));
    
            return buffer;
        }
    

    The problem is that at server side I see LOG_IN event only inside compiled library jetserver-0.1.jar.

    So how am I supposed to implement this kind of feature without touching the library?

  • Changing game room

    Changing game room

    Hi menacher,

    Thanks man for that great job you've done. But I little confused with changing room without closing current PlayerSession. How can I implement this? I tried:

            oldRoom.disconnectSession(playerSession);
            newRoom.onLogin(playerSession);
            newRoom.connectSession(playerSession);
    

    But after this I have two NetworkEventHandlers for one player session. Hence I have duplication of events processing.

    Are you sure that JetlangEventDispatcher.removeHandlersForSession works properly? I think it should be like that:

    public synchronized boolean removeHandlersForSession(Session session)
    {
        LOG.trace("Entered removeHandlersForSession for session {}", session);
        List<EventHandler> removeList = new ArrayList<EventHandler>();
    
        Collection<List<EventHandler>> eventHandlersList = new ArrayList<List<EventHandler>>(
                handlersByEventType.values());
        eventHandlersList.add(anyHandler);
    
        for (List<EventHandler> handlerList : eventHandlersList)
        {
            removeList.addAll(getHandlersToRemoveForSession(handlerList,session));
        }
    
        LOG.trace("Going to remove {} handlers for session: {}",
                removeList.size(), session);
        for (EventHandler handler : removeList)
        {
            removeHandler(handler);
        }
    
        return (removeList.size() > 0);
    }
    

    And GameRoomSession.disconnectSession should be like that:

    public synchronized boolean disconnectSession(PlayerSession playerSession)
    {
        final boolean removeHandlers = this.eventDispatcher.removeHandlersForSession(playerSession);
        return (removeHandlers & sessions.remove(playerSession));
    }
    

    For removing player session from room even if no handlers were removed.

  • How to send events from player's session to game room's session?

    How to send events from player's session to game room's session?

    Hi Abraham,

    Could you please explain how to send events from player's session to game room's session? You wrote: The player session's listen on the Game Room session for any outgoing network data using event handlers. The player sessions have a reference to their Game Room using a parentGameRoom variable and can send data to it using onEvent. Do I understand correct that I have to do next steps in player's handler:

    1. Call getSession() to get player's session.
    2. Cast this session to PlayerSession.
    3. Call getParentGameRoom of this PlayerSession.
    4. Cast room to GameRoomSession.
    5. Call onEvent() of this GameRoomSession.

    I think this should be a little easier:

    1. Call getSession() to get player's session.
    2. Call onEvent() of this session.
    3. GameRoomSession catches raised event and handles it.

    In this case I have to add a custom handler to GameRoomSession.

    Perhaps such a mechanism is already provided and I'm just inattentive?

  • room.sendBroadcast(networkEvent) is not working

    room.sendBroadcast(networkEvent) is not working

    Option 1 is not working NettyMessageBuffer outBuf = new NettyMessageBuffer(); outBuf.writeInt(GameRoomCommands.MY_EVENT.getCommand()); NetworkEvent networkEvent = Events.networkEvent(outBuf); gameRoom.sendBroadcast(networkEvent);

    Option 2 is working! NettyMessageBuffer outBuf = new NettyMessageBuffer(); outBuf.writeInt(GameRoomCommands.MY_EVENT.getCommand()); NetworkEvent networkEvent = Events.networkEvent(outBuf);

    Iterator itr = gameRoom.getSessions().iterator(); while (itr.hasNext()) { PlayerSession playerSession = (PlayerSession) itr.next(); playerSession.getTcpSender().sendMessage(networkEvent); }

    This gameRoom is not is not registered in lookupService. Initially I have only one connectGameRoom which accepts all the incoming connection. (refKeyGameRoomMap.put("CONNECT_ROOM_REF_KEY", game.getConnectGameRoom());)

    After enough players are connect, another gameRoom is created and sessions are added to it.
