Define an event in a world?

Hi, I want to make the event I am using only work in a certain world that I choose and not in all worlds can you help me?

public function onEnable(){
$this->getLogger()->info("ComboFFA - activated!");
@mkdir($this->getDataFolder());
$this->saveDefaultConfig();
$this->getResource("config.yml"); $this->getServer()->getPluginManager()->registerEvents($this,$this);
}

public function onHit(EntityDamageByEntityEvent $event){
$entity = $event->getEntity();
$damager = $event->getDamager();
if($entity instanceof Player && $damager instanceof Player){
$event->setAttackCooldown(0);
}
}
return false;

public function onDeath(PlayerDeathEvent $event) {
$player = $event->getPlayer();
$name = $player->getName();
$entity = $event->getEntity();
if($entity instanceof Player){
$event->setDrops([]);
}
}

 

if ($player->getLevel === $this->getServer()->getLevelByName($world)){
//Do something
}

 

Will you go under the event?

public function onHit(EntityDamageByEntityEvent $event){
$entity = $event->getEntity();
$damager = $event->getDamager();
if($entity instanceof Player && $damager instanceof Player){
$event->setAttackCooldown(0);
if ($player->getLevel === $this->getServer()->getLevelByName($world)){
//Do something
}
}
}

 

public function onHit(EntityDamageByEntityEvent $event){
$entity = $event->getEntity();
$damager = $event->getDamager();
if($entity instanceof Player && $damager instanceof Player){
$event->setAttackCooldown(0);
if ($player->getLevel() === $this->getServer()->getLevelByName($world)){
//Do something
}
}
}
:spoonfed:

 

Excuse me what it means :spoonfed: ?

 

Meaning you had to be treated like a baby and me holding the spoon into your mouth

 

the code on the $ player variable gave me an error

 

duh since you didnt define it.

 

Yand how do I define it so that only in that world that I choose to execute that event and not in all the worlds?

 

Quit joking.I already gave you the full code and no im not going to help anymore.

 

Thanks for helping me, I didn't think you were a delicate person, your help is appreciated, regards
