get faction of player

Hi everyone, I'm doing a McMMO plugin, but in spades ability, the same faction player can advance levels of swords by beating a member of the same faction, how do I block this using FactionPro functions?

I used this:

Code:

Swords.php

PHP:

public function onDamage(EntityDamageEvent $ev){
        if(!$ev instanceof EntityDamageByEntityEvent){
            return;
        }
   
        if($ev instanceof EntityDamageByEntityEvent){
            if($ev->getDamager() instanceof Player){
                if($ev->isCancelled()){
                    return;
                }
   
                $entity = $ev->getEntity()->getName();
                $player = $ev->getDamager()->getName();
   
                $faction = $this->pl->getServer()->getPluginManager()->getPlugin("FactionsPro");
                if($faction->getPlayerFaction($entity) == $faction->getPlayerFaction($player)){
                    $this->pl->getServer()->getLogger()->info("CONDITION TEST. The two players are from the same faction");
                    return;
                }
   
            }
        }
    }


but nothing happens... Not even a mistake...

 

Try with this inside your if()

PHP:

$faction->sameFaction($entity, $player);


Also lines 3, 4 and 5 don't make sense if you're going to check the same thing below.
