Игрок-убийца.

Нужно у Player есть метод позволяющий узнать причину последнего урона.

Code:

  @EventHandler
public void onJoin (PlayerJoinEvent event){
Regions.getSelector().setSelMode(event.getPlayer(),false);
}

[pre][code]public void onDeath (PlayerDeathEvent event){
    Player damager = getDamager(event.getEntity().getLastDamageCause());
    if (damager==null) return; // Игрок умер не в PVP
}

private Player getDamager(EntityDamageEvent event){
    Player player = null;
    if (event.getEntity() instanceof Player) player = (Player) event.getEntity();
    else if (event instanceof EntityDamageByEntityEvent) {
        Entity damager = ((EntityDamageByEntityEvent) event).getDamager();
        if (damager instanceof Player) player = (Player) damager;
    } else if (event instanceof EntityDamageByChildEntityEvent) {
        Entity damager = ((EntityDamageByChildEntityEvent) event).getDamager();
        if (damager instanceof Player) player = (Player) damager;
    }
    return player;
}
