Bukkit runnable issue

Hi guys,

I've seen a video about custom tablists, and I've tried to reproduce the same code as he did. But my code isnt working, and my console if sending my errors :




The video link :

My code:

Code:

private boolean titlechanged;
    @Override
    public void onEnable() {
        getServer().getConsoleSender().sendMessage(ChatColor.DARK_GREEN + "\n\n[HUB] plugin by Praxounet has been activated.\n");
        getServer().getPluginManager().registerEvents(new EventsClass(), this);
     
        new BukkitRunnable() {

            @Override
            public void run() {
                PacketPlayOutPlayerListHeaderFooter packet = new PacketPlayOutPlayerListHeaderFooter();
                Object header = new ChatComponentText("yo");
                Object footer = new ChatComponentText("too");
                try {
                    Field a = packet.getClass().getDeclaredField("a");
                    a.setAccessible(true);
                    Field b = packet.getClass().getDeclaredField("b");
                    b.setAccessible(true);
                 
                    a.set(packet, header);
                    b.set(packet, footer);
                 
                    if(Bukkit.getOnlinePlayers().size() == 0) return;
                    for (Player player : Bukkit.getOnlinePlayers()) {
                        ((CraftPlayer) player).getHandle().playerConnection.sendPacket(packet);
                    }
                 
                 
                } catch (NoSuchFieldException | IllegalAccessException e) {
                    e.printStackTrace();
                }
             
             
            }
         

         
         
        }.runTaskTimer(this, 0, 20);
 
     
     
     
     
     
     
        }

Any ideas ?

 

Yea, the error pointed to the part of the catchphrase, I have 2 ideas. change it to catch ((No SouchFieldException | IllegalAccessException) e) or just double look at the code.

Another problem might be version specific, what version you using?

 

@Praxounet

It looks like the video uses very dirty reflection. You are trying to use variables that do not exist in your bukkit/minecraft environment.
Are you using the same bukkit version as the video?

 

Hmm I'm not sure to be honest. I'll ask people on his discord.
