NameTag of entities do not visible

I just set nametag for entities on EntitySpawnEvent but the nametag of entities do not visible . I have tried to use setNameTagVisible(true) and setNameTagAlwaysVisible(true) but both dont work for me @@ Anyone know how to make nametag of entity visible ?Thanks

 

But when you hover over the entity, is it visible?

 

No ((
My code :

Code:

    public function onEntitySpawn(EntitySpawnEvent $e) {
        $mobs = $e->getEntity();
        if($mobs instanceof Zombie || $mobs instanceof Skeleton || $mobs instanceof Spider){
            foreach($this->main->getServer()->getOnlinePlayers() as $p) {
                $level = $this->main->getLevel($p);
                //if($mobs->distance($p) <= 50) {
                    $name = $mobs->getNameTag();
                    $mobs->setNameTag($name."\nLevel ".$level);
                    $mobs->setNameTagVisible(true);
                    $mobs->setNameTagAlwaysVisible(true);
                //}
            }
        }
    }

 

While I don't know about your nametag display issue, I'd suggest running a check through a different function, like isNearPlayer($mobs), and if the mob is within range, break the foreach loop and return true. That way, in your listener, you could just use

PHP:

if($this->main->isNearPlayer($mobs)){
  //set the entities nametag once, rather than 2 or 3 times if there are more players within range.
} else {
  //No players are within range of the entity.
}

Also, I believe you can use

PHP:

 if($mobs instanceof (Zombie || Skeleton || Spider)) {
}

to make it easier than writing out the $mobs instanceof so many times.

 

I want every entities that spawn with specific nametage
