How to get a killer with custom snowball?

So I made so the snowball damages the players but how can I get a killer via the snowball??

Here's my code for damage, Idk how to get killer via the custom snowball hit.

Code:

    @EventHandler(priority=EventPriority.HIGH)
    public void onSnowBall(EntityDamageByEntityEvent event) {
        if(event.getDamager() instanceof Snowball && event.getEntity() instanceof Player){
            Player player = (Player) event.getEntity();
            player.damage(2);
        }
    }

 

Check if damager is a Snowball, then cast the damager to Snowball (or Projectile) and check if .getShooter() is an instance of Player then cast .getShooter() to player and you have the killer.

Ps: use EntityDeathEvent

 

ok thanks man!
