Glowing for one Person

@AlvinB
I made it with an ArrayList But Thank you SOOOO much!

How would you do a SET ?

 

@TheLastDeamon
A Set is a bit more appropriate (since duplicates and order aren't important in this case), but it doesn't really make any difference.

Anyways, glad that you solved it! Would you mind marking this thread as solved?

 

After I tried

@AlvinB

Only one porblem:
The Players glow for themselves, too
Probably also for other Players but I'm not sure about that. Yep for other players too!

Code:java

 
    ProtocolLibrary.getProtocolManager().addPacketListener(new PacketAdapter(this, PacketType.Play.Server.ENTITY_METADATA, PacketType.Play.Server.NAMED_ENTITY_SPAWN) {
    @Override
    public void onPacketSending(PacketEvent event) {
 
     if (seeGlow.contains(event.getPlayer()))
     {
       for (Player player : Bukkit.getOnlinePlayers())
  {
       if (/*has a player with*/player.getEntityId() == event.getPacket().getIntegers().read(0)) {
    if (event.getPacketType() == PacketType.Play.Server.ENTITY_METADATA) {
    List<WrappedWatchableObject> watchableObjectList = event.getPacket().getWatchableCollectionModifier().read(0);
    for (WrappedWatchableObject metadata : watchableObjectList)
    {
       if (metadata.getIndex() == 0) {
      byte b = (byte) metadata.getValue();
      b |= 0b01000000;
      metadata.setValue(b);
      }
    }
    } else {
       WrappedDataWatcher watcher = event.getPacket().getDataWatcherModifier().read(0);
       if (watcher.hasIndex(0)) {
    byte b = watcher.getByte(0);
    b |= 0b01000000;
    watcher.setObject(0, b);
       }
      }
     }
    }
   }
  }
});

Code:java

@EventHandler
   public void onPlayerInteract(PlayerInteractEvent e)
   {
     if(e.getPlayer().getInventory().getItemInMainHand().getType() == Material.SPECTRAL_ARROW)
       if(e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK)
       {
         e.getPlayer().sendMessage("Click accepted!");
         seeGlow.add(e.getPlayer());
         for (Player p : Bukkit.getOnlinePlayers())
         {
           if(p != e.getPlayer())
           {
             e.getPlayer().hidePlayer(p);
             e.getPlayer().showPlayer(p);
           }
         }
       }
   }

 

@TheLastDeamon
Just add a check to make sure that event.getPlayer() doesn't equal player in the for loop.

 

@AlvinB
What I ment was that the players, who are supposed to glow, see themselves and everyone else glow!
The one who clicked doesn't glow!
and do you mean like this:

Code:java

ProtocolLibrary.getProtocolManager().addPacketListener(new PacketAdapter(this, PacketType.Play.Server.ENTITY_METADATA, PacketType.Play.Server.NAMED_ENTITY_SPAWN) {
    @Override
    public void onPacketSending(PacketEvent event) {
 
     if (seeGlow.contains(event.getPlayer()))
     {
       for (Player player : Bukkit.getOnlinePlayers())
       {
         if(player != event.getPlayer())
           if (/*has a player with*/player.getEntityId() == event.getPacket().getIntegers().read(0)) {
            if (event.getPacketType() == PacketType.Play.Server.ENTITY_METADATA) {
             List<WrappedWatchableObject> watchableObjectList = event.getPacket().getWatchableCollectionModifier().read(0);
             for (WrappedWatchableObject metadata : watchableObjectList)
            {
             if (metadata.getIndex() == 0) {
                byte b = (byte) metadata.getValue();
                b |= 0b01000000;
               metadata.setValue(b);
        }
      }
      } else {
         WrappedDataWatcher watcher = event.getPacket().getDataWatcherModifier().read(0);
         if (watcher.hasIndex(0)) {
      byte b = watcher.getByte(0);
      b |= 0b01000000;
      watcher.setObject(0, b);
         }
      }
      }
  }
     }
    }
  });
