Solved Scheduler causes disconnect.genericReason

Hi, I'm trying to make a afk plugin. Player should be AFK whenever he doesn't move for 30 secs. Now, everytime I move, I get kicked. Console: lost connection: disconnect.genericReason.

PHP:

 
   HashMap<Player, BukkitTask> map = new HashMap();
 
 
On p move...
 
 
        if (map.get(p) != null) {
             
            map.get(p).cancel();
            }
         
            BukkitTask bt = Bukkit.getScheduler().runTaskLater(plugin, new Runnable() {
                public void run() {
                    sp.sendMessage(ChatColor.DARK_RED + "You're now away from keyboard.");
                    sp.setTitle(ChatColor.DARK_RED + "AFK");
         
 
                 
                 
                }
            }, 600);
            map.put(p, bt);
         
            

 

what version of craftbukkit are you using?

 

1.4.7-R1.0

 

Does the console give you any error messages aside from the generic disconnect?

 

LudicrousYoshi Nope, only the disconnecting.

 

More context may help in identifying the issue.

 

ok since I can't see anything directly wrong with what you have, I'd like you to try this diagnosing technique I use.

Put a log.info message after every single line just with like a number 1 through n and see how many numbers the console prints before it disconnects you. This way you can see what line is actually the cause of the disconnect, or at least rule out the lines after the disconnect.

Another thing, it probably isnt, but i wouldnt discount trying to run it with a 1.5 dev server in case 1.4.7 R1 has some random unknown error nobody has noticed yet.

 

Code:

Bukkit.broadcastMessage("0");
            if (map.get(p) != null) {
           
           
            map.get(p).cancel();
            }
           
            Bukkit.broadcastMessage("1");
            BukkitTask bt = Bukkit.getScheduler().runTaskLater(plugin, new Runnable() {
               
                public void run() {
                    sp.sendMessage(ChatColor.DARK_RED + "You're now away from keyboard.");
                    sp.setTitle(ChatColor.DARK_RED + "AFK");
           
 
                   
                   
              }
            }, 600);
            Bukkit.broadcastMessage("2");
            map.put(p, bt);
            Bukkit.broadcastMessage("3");

Console goes prints 0 1 2 3
Connection reset

Humor me and try it on a 1.5 server xD

It would also be nice if you could post more of the class since the problem doesnt appear to be directly in the block of code you posted. I'm also assuming this is the only plugin running at the moment, correct?

 

1. I can't, the sense of the plugin is changing the player title with spout, and there's no spoutplugin 1.5 build.
2. Its with spout and another plugin by me the only one.
3.

    }

    public void onMove(PlayerMoveEvent e) {

        right.setY(loc.getY()-1);
       
   
        if (((int) loc.getX()) != ox ||((int) loc.getZ()) != oz) {
       
           
           
            ox = (int) loc.getX();
            oz = (int) loc.getZ();
           
            /*
            final SpoutPlayer sp = (SpoutPlayer) p;
            sp.setTitle(null);
           
           
            if (map.get(p) != null) {
           
           
            map.get(p).cancel();
            }
           
       
            BukkitTask bt = Bukkit.getScheduler().runTaskLater(plugin, new Runnable() {
               
                public void run() {
                    sp.sendMessage(ChatColor.DARK_RED + "You're now away from keyboard.");
                    sp.setTitle(ChatColor.DARK_RED + "AFK");
           
 
                   
                   
              }
            }, 600);
           
            map.put(p, bt);
       
            */
           
           
           
        }
       
       
       
       
    }
   
   
 
   
   
}

 

Alright try my diagnosing thing again but put a broadcast before every block code in the onMove. There should probably be about 10 or more; the more you have the more precise you can be about what is happening. The reason I'm asking you to do it with the whole event is because I want to see if the problem might be happening halfway through the second call and this will help you see if it is actually even making it to a second call.

PS- will be gone for a few hours, sorry if I don't respond quickly next time.

 

LudicrousYoshi , Every line get called before kicking me.

LudicrousYoshi I found the mistake! Players title cannot be null, it needs to be "". Thank you really much for your help!

Not sure if I actually helped that much haha, but you're welcome!
