onAttack

I got this Problem with my plugin when I Start my Server:
[11:34:25] [Server thread/CRITICAL]: ParseError: "syntax error, unexpected 'public function onAttack' (T_STRING), expecting function (T_FUNCTION) or const (T_CONST)" (EXCEPTION) in "plugins/command/src/hunger/hunger" at line 12

This is my Code:

<?php

namespace hunger;

use pocketmine\entity\Entity;
use pocketmine\event\entity\EntityDamageByEntityEvent;
use pocketmine\event\entity\EntityDamageEvent;
use pocketmine\event\Listener;

class onAttack extends PluginBase implements Listener{

public function onAttack(\pocketmine\event\entity\EntityDamageEvent $e)
{
if($e instanceof \pocketmine\event\entity\EntityDamageByEntityEvent){
if($event->getEntity() instanceof Player && $event->getDamager() instanceof Player){
if($e->getDamager()->getInventory()->getItemInHand()->getId() == 1){
$e->getEntity()->sendMessage("You have been spotted with a stone");
$e->getDamager()->sendMessage("You spot a player with stone!");
}
}
}
}
}

 

I don't think that error comes from the code you sent there, I ran it through a syntax checker and it shows no errors.
