Server-sided character unstucker

[FateJiki]

Yeah, I know there are some offline unstuckers, but these are better as they disconnect an already logged-in player.

Go to net.channel.handler.playerloggedinhandler.java


Look for :

boolean allowLogin = true;
        ChannelServer channelServer = c.getChannelServer();

Replace

WorldChannelInterface worldInterface = channelServer.getWorldInterface();
				if (state == MapleClient.LOGIN_SERVER_TRANSITION) {
					for (String charName : c.loadCharacterNames(c.getWorld())) {
						if (worldInterface.isConnected(charName)) {
							
							allowLogin = false;
							break;
						}
					}
				}

With this :

WorldChannelInterface worldInterface = channelServer.getWorldInterface();
                if (state == MapleClient.LOGIN_SERVER_TRANSITION) {
                    for (String charName : c.loadCharacterNames(c.getWorld())) {
                        if (worldInterface.isConnected(charName)) {
                           System.err.print(charName + " has been unstucked, for bug-testing purposes.");
                            MapleCharacter player_to_dc = player.getClient().getChannelServer().getPlayerStorage().getCharacterByName(charName);
                            player_to_dc.getClient().disconnect();
                            player_to_dc.getClient().getSession().close();
                             c.getSession().write(MaplePacketCreator.serverNotice(1, "\r\n\r\n\r\n Player was unstuck.\r\n Please re-log"));
                            player_to_dc.getMap().removePlayer(player_to_dc);
                            allowLogin = false;
                            break;
                        }
                    }
                }

Information:
Basically, you know whenever your character is stuck on the channelserver, it keeps you from logging in , and on the channel-server bat window, you see something like "[h4x] Player is trying to double-login "

Well, what this basically does is that it disconnects the stuck player and then makes you re-login so you can connect. (Duping shouldn't be possible).

Report any bugs you may encounter, I've used this on my server and it seems good. ~

This was tested on Arber (v75) and Shootsource(v75) .

Very Nice, Testing Now

 

[.:LastBreath:.]

Hmm, Looks good...

 

[watzmename]

Pretty sure this has been released a long time ago. I've seen it somewhere.

I haven't seen this before, but if you have, please post the thread link .

If it has been released, I apologize.

 

[~Delta]

This has been released back in 2009.. I'm 200% sure

 

[rice]

So you're releasing something that is already in a repack?

You're quite cruel to say this out loud.

 

[Cappe]

Then proof it instead of flaming.

 

[LightPepsi]

if (worldInterface.isConnected(charName)) {

You guys should really think before you do something.
If a character isn't removed from the HashMap of PlayerStorage, it'll still return true.


Also, if you got everything well planned before coding new contents it will not cause any character stuck problem at all.

 

[FateJiki]

Alright guys, instead of posting that you've seen this before, post the freaking link to the thread containing the original content, instead of spamming the same thing .

 

[Buya]

you dc the player and them send him a message...?
also you would dc a player even if hes not stuck.

It's up to the player to keep his information private.

That's the way I work.

 

[Emilyx3]

This probably hasn't been explicitly released, I haven't seen it before in any repack.

I've used this method for quite a while now, except without the notice (I might add that, thanks for the idea).

Edit: Btw, @lightpepsi disconnect() should handle removing the character from maps/channels and the rest of the cleanup.

 

[NyCPirate]

Well this looks fairly decent to me Good job =)

 

[King Grub]

I excuse for the bump but what the hell.

Can someone confirm, that this 'method' is secure and suitable for a mass populated server (not refering to my server, just incase ) :laugh:

And according to me transition ° loggedin 1, people who are stuck have 2 right 0_0?

 

[King Grub]

And according to me transition ° loggedin 1, people who are stuck have 2 right 0_0?

seems to be correct..

   public static final int LOGIN_NOTLOGGEDIN = 0;
    public static final int LOGIN_SERVER_TRANSITION = 1;
    public static final int LOGIN_LOGGEDIN = 2;

so

if (state == MapleClient.LOGIN_SERVER_TRANSITION) {

should be

if (state == MapleClient.LOGIN_LOGGEDIN) {

:blink:

 

[Cappe]

Err.. 2 is loggedin, and 1 is stuck

 

[Deagan ツ]

Err.. 2 is loggedin, and 1 is stuck

idk but mos tpeople who are stuck are still in game 0_0. so no, it's 2.
