Simple Chat Plugin Help

Hey! What should I put in the Main.php if I want to make a plugin that sends a private message to a player like the /tell but that can be use with the NPCs of slapper and don't have the name of [Server] in the chat. I don't know almost nothing about plugin development but I want to learn I only have this:
<? php

namespace masterkiller\SlapperChat;

use pocketmine\plugin\PluginBase;
use pocketmine\command\Command;
use pocketmine\\CommandSender;
use pocketmine\Player;
use pocketmine\utils\TextFormat;

class SlapperChat extends PluginBase {
public function SlapperChat

 

I'm making a plugin for this right now

 

Here is the link: https://poggit.pmmp.io/ci/isPops/PrivateMessenger/PrivateMessenger

Command For Slapper ( slaptell )
Command to setup slapper ( /slapper edit slapperID addcommand rca {player} slaptell )
That's it

 

Thanks! After "rca", in {player} I put the name I want the slapper have?

 

no to create slapper
you do /slapper create human nameYouWantItToBe

 

Then do /slapper id
and smack npc
then do /slapper edit npcID addcommand rca {player} slaptell
just like that

 

Oh, ok thanks

 

I put the command with the message I want it to say in the space of (message), like this "/slapper edit 235 addcommand rca {player} but when I click the slapper, it tells me to write the name of the player, then I write it and it says the player doesn't exists.

 

yes because the player your trying to send message to doesnt exist

 

after you type a name of person online that isnt yours you could then type the message and thats it

 

if you change your mind about sending message to player just type cancel in chat

 

Ooohhh, I think you got wrong what I want to do from the beginning, I just want to use the command tell {player} with the slapper, but when it sends the message, to the player that hit it, don't have the name of [Server] and use the name of the slapper. For example: I put this command on the slapper, /slapper edit (slapperid) addcommand tell {player} (message), with this command the slapper sends a message to the player that hit it, but the message appears like this: [Server --> (Playerx)] (message). And I just want that instead of that just appears the name of the slapper and the message

 

Oh that wouldve been way easier lol

 

But ill make that tmw

 

Yeah, sorry for not explaining myself better lol

 

Can you reply when you make the other plugin?
