Beginner Plugin Designer Needs a little help!

I currently have this code but when I try and call the onPlayerDeath() listener it wont work. Their are very few documentations for problems like this. Please Help me. Tell me what is wrong with my code?!?!?

Code:

<?php

namespace CyberTech;

use pocketmine\Player;
use pocketmine\Server;
use pocketmine\event\Listener;
use pocketmine\event\player\PlayerEvent;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerQuitEvent;
use pocketmine\event\player\PlayerDeathEvent;
use pocketmine\event\entity\EntityDeathEvent;
use pocketmine\event\entity\EntityLevelChangeEvent;
use pocketmine\level\Position;
use pocketmine\math\Vector3;
use pocketmine\permission\Permission;
use pocketmine\plugin\PluginBase;
use pocketmine\utils\Config;
use pocketmine\utils\TextFormat;

class Functions extends PluginBase implements Listener{
   
        public function __construct(Main $plugin){
        $this->plugin = $plugin;
    }
   
   
       public function onPlayerDeath(PlayerDeathEvent $event){
    $player = $event->getEntity();   
        $this->getLogger()->info("Arena[1]:".$player);
                return  $this->getLogger()->info("Arena[1]:".$player);;
    }
   
    public function startfight1($sender, $arena, array $args){
     $this->getLogger()->info("Sender:".$sender);
     $this->getLogger()->info("Arena:".$arena);
     $this->getLogger()->info("Args:".$args[0]);
     $this->getLogger()->info("StartFight has been called!");
      return true;
    }
   
}
?>

Just one question... Are you using an IDE to code?

lol NutBeans Yes

lol NutBeans Yes, Why?

Nutbeans...
When I search Nutbeans in google, no such thing！
It should be NetBeans

Lol NetBeans

Have you implemented the EventListener in the main class?

Yes I Have.

Code:

use pocketmine\event\Listener;

Thanks, Hope it works now

Nope No Luck... I get the OnEnabled And onDisabled to work but not OnPlayerDeath or onPlayerJoin.

Could someone type out a basic Main.php plugin that said Hi when you join for me?
So I can try and have a reference to go off of.

I know you dont have yo have the OnEnable and OnDisable but i just want the onPlayerJoin to happen...

Do not return anything while you use events! Just put the code

Did you registered the Class as an event handler?

What is this file? Is this the main class of something else? Why did you require a Main parameter in the constructor if it is the main class? Why does it extend PluginBase otherwise?

can u update ur current code because its totally messy or quite wrong.

THis was my promblem.

Please upload the WHOLE code to Github and provide us the link to it, so we can help you

public function not work if there was 4 lines
