Remove NPC from Tab List and Get NPC's Coordinates

A Bukkit plugin that I am working on right now adds an NPC to the game, but I have several problems with it:

1.) The NPC shows up in the Online Players Tab list, and I would like to prevent this from happening.
2.) I need to add a command to the plugin that will display the NPC's Coordinates to the player.

How can I do this? Here is the class from my project that creates the NPC's GameProfile.

 

1. 1.

Code:

Packet201PlayerInfo packet = new Packet201PlayerInfo("HumanNPC", false, 0); //the packet to hide the given players name from tab
for(Player online : Bukkit.getOnlinePlayers()) {// get all online players
          ((CraftPlayer)online).getHandle().netServerHandler.sendPacket(packet);// send that packet to all players

2.

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String label, String []args){
        if (label.equalsIgnoreCase("Coordinates")) { //the command code
Player player = (Player) sender; // get who sent the command
player.sendMessage(HumanNPC.getLocation() + "Is where the npc is located."); //send the player a message, containing the npcs coordinates, or do this (seems like a better idea)
player.sendMessage("X: "+ HumanNPC.getLocation().getX())
        }
        return false;
}

Untested, but should work. Let me know if you need anything.

 

Check cmd.getName().equalsIgnoreCase(string) instead of label.equalsIgnoreCase(string), it's a good habit to get into, and it allows for aliases. Secondly, check before casting sender to player!

 

and third, sending a raw Location object looks ugly. (It's either Location@hashcocde or CraftWorld{name:world},x=69,y=69,z=69 I don't remember it)

 

You would probably want to do something like this:

Code:

player.sendMessage("X: " + HumanNPC.getLocation().getX() + //y and z values as well)

 

Can't believe I forgot to do that check I normally always do.. Also I think your way of getting the location would be better, mine doesn't seem right to me.

 

You also might want to include the world that the NPC is in, especially if the server has several worlds.
