Detecting when a user logs into a server?

How do i detect when a user logs into the server with forge?

Hi

 

NetLoginHandler.initializePlayerConnection() has a forge call to

FMLNetworkHandler.handleClientConnection() which contains this fragment:

        case LOGIN_RECEIVED:

            // mods can try and kick undesireables here

            String modKick = NetworkRegistry.instance().connectionReceived(netLoginHandler, netLoginHandler.myTCPConnection);

 

which I think you can access using NetworkRegistry.registerConnectionHandler.

There also appears to be handlers for

playerLoggedIn, clientLoggedIn, and a couple of others.  See IConnectionHandler.

 

That's all I know, I've never actually tried this.  But it does look promising.

Hello,

 

Here is an example of the IConnectionHandler i use to print my update message:

 

 

public class ConnectionHandler implements IConnectionHandler
{
@Override
public void playerLoggedIn(Player player, NetHandler netHandler, INetworkManager manager)
{
	if (Config.NEW_VERSION)
	{			
		((EntityPlayer)player).addChatMessage(Config.GetStringLocalization("NEW_VERSION_MESSAGE"));
	}
}

@Override
public String connectionReceived(NetLoginHandler netHandler, INetworkManager manager)
{
	return null;
}

@Override
public void connectionOpened(NetHandler netClientHandler, String server, int port, INetworkManager manager)
{

}

@Override
public void connectionOpened(NetHandler netClientHandler, MinecraftServer server, INetworkManager manager)
{

}

@Override
public void connectionClosed(INetworkManager manager)
{

}

@Override
public void clientLoggedIn(NetHandler clientHandler, INetworkManager manager, Packet1Login login)
{

}

 

 

You have to register it like this:

 

NetworkRegistry.instance().registerConnectionHandler(new ConnectionHandler());

 

Hope that helps.

Extending on this; is it possible to make a mod only work when a user connects to a specific server? I may be making a private mod for someone, and by doing that they can test it out while it's being worked on.

I was making same thing, but that was like a year ago? (1.2.5)

GuiMainMenu uses GuiConnecting which uses Threads that handle ip's and ports - in that times (1.2.5) there wasn't any method capable of doing what you want so I used it. But from what I remember (which is really sad) I added one boolean to vanillia code which is later used(Client.SIDE) by Forge mod (which checks if this is "the" server). Since that was a private server I just told them that whenever they make a new pack they should put this one file into minecraft.jar. This might be a solution if you won't find anything better. ;/

 

2min in code and I got this: (Don't ask me, am just giving a hint ;p)

ServerAddress.class

    public String getIP()
    {
        return this.ipAddress;
    }
    private static String[] getServerAddress(String par0Str)
