1.8.8 One Hit to get two Damage event....How to fix it.

First, Sorry for not good English.

The problem is
When I use this code and hit player with barrage,
Damager got 1 hit and attacker get two times EntityDamageByEntityEvent..

Code (Text):

    public void onEntityDamage(EntityDamageByEntityEvent event)
    {

        if (event.getDamager() instanceof Player && event.getEntity() instanceof Player)
            {
                Player player = (Player) event.getEntity();
                player.playSound(player.getLocation(), Sound.ORB_PICKUP, 10, 10);
            }
       

    }

Specifically, I got two orb sound when I hit player once.

How to fix it.
I tried to use this code too

Code (Text):

    public void onEntityDamage(EntityDamageByEntityEvent event)
    {
        Entity damager = event.getEntity();
       
        if(damager instanceof Player && event.getDamage() <= 0)
        {
        }
        else
        {
            if (event.getDamager() instanceof Player && event.getEntity() instanceof Player)
            {
                Player player = (Player) event.getEntity();
                player.playSound(player.getLocation(), Sound.ORB_PICKUP, 10, 10);
            }
        }

    }

But didn't fix.

Please your opinions!!

 

What do you mean?

I got two sounds when I hit once.

 

Here is main class

Code (Text):

    public void onEnable()
    {
        getServer().getPluginManager().registerEvents(new AAA(), this);
        getServer().getPluginManager().registerEvents(new BBB(), this);
        getCommand("kit").setExecutor(new Cmds(this));
        super.onEnable();
    }
   

 

Code (Text):

import org.bukkit.Sound;
import org.bukkit.entity.Entity;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageByEntityEvent;

public class AAA implements Listener
{
    @EventHandler
    public void onEntityDamage(EntityDamageByEntityEvent event)
    {
        Entity damager = event.getEntity();
   
        if(damager instanceof Player && event.getDamage() <= 0)
        {
        }
        else
        {
            if (event.getDamager() instanceof Player && event.getEntity() instanceof Player)
            {
                Player player = (Player) event.getEntity();
                player.playSound(player.getLocation(), Sound.ORB_PICKUP, 10, 10);
            }
        }

    }
