How to add gameclient to restored offliners traders shop


Question

Posted

Hello.  

I have a problem that I would like to ask for help: how to add gameClient to a restored offline shop character when the server is restarted?

I added offline traders shop/craft on my ACiS l2j but I have a situation: If I don't add a client for the char I won't be able to login again, since it can not be kicked when trying to login (it keeps sending the message account is in use). If I try to add, it gives an nullpointerexception and the char is not loaded with it's private store/craft to the game.

 

Here is the exception:

May 09, 2020 12:48:50 PM net.sf.l2j.gameserver.datatables.OfflineTradersTable <init>
WARNING: error loading trader 268487086.
java.lang.NullPointerException
        at net.sf.l2j.gameserver.network.gameserverpackets.PlayerAuthRequest.<init>(PlayerAuthRequest.java:11)
        at net.sf.l2j.gameserver.LoginServerThread.addClient(LoginServerThread.java:305)
        at net.sf.l2j.gameserver.datatables.OfflineTradersTable.<init>(OfflineTradersTable.java:470)
        at net.sf.l2j.gameserver.datatables.OfflineTradersTable$SingletonHolder.<clinit>(OfflineTradersTable.java:552)
        at net.sf.l2j.gameserver.datatables.OfflineTradersTable.getInstance(OfflineTradersTable.java:547)
        at net.sf.l2j.gameserver.GameServer.<init>(GameServer.java:270)
        at net.sf.l2j.gameserver.GameServer.main(GameServer.java:118)
 

This exception occurs when this line is called:

LoginServerThread.getInstance().addClient(player.getAccountName(), client);

 

 

The part of the code just before the exception is throwed:

....

                    player.setRunning();
                    player.sitDown(true);
                    player.setOnlineStatus(true, false);
                    
                    World.getInstance().addPlayer(player);
                    
                    final GameClient client = new GameClient(null);
                    client.setDetached(true);
                    player.setClient(client);
                    client.setPlayer(player);
                    client.setAccountName(player.getAccountNamePlayer());
                    player.setOnlineStatus(true, true);
                    client.setState(GameClientState.IN_GAME);
                    player.setOfflineStartTime(time);
                    player.spawnMe();
                    
here ->                    LoginServerThread.getInstance().addClient(player.getAccountName(), client);
 

Thanks in advance

Set the timer for offline/storeMe the player.

Disconnect the offline trader at logout/exit.

You need to (if you want to) store the offline traders at server restart/shutdown and restore them back at server restart.

 

Please tell us what and how have you tried to do it and someone will try to assist you.

Thank you for answering.  How I made it? Well, I got a patch for Offline traders somewhere but when applying the patch in aCis, it usually comes some mismatches. I corrected those mismatches and it works fine in almost everything. Almost! When I mount a private store and exit the game the offline trade works. The char continues on the game with the private store. And it is also stored in the database. So when I restart the server, the private store comes back. So far so good... the problem is: when I try to reconnect to the game again with the same account it keeps telling account in use and does not disconnect the char, so I can enter in the game again. So the char will be locked until I delete the private store from the database and do the next restart. And I think what causes that is because I commented the following line when restoring the private stores from database:

LoginServerThread.getInstance().addClient(player.getAccountName(), client);

If I don't comment it, the private store is not loaded and the above exception is thrown.
