    Hey guys ive recently developed a bosses plugin I set the health above the bosses head as $entity->setNameTag("Health: " . $entity->getHealth() . "/" . $entity->getMaxHealth() . " ❤"); but when attacked the health doesn't update or change anybody know how to help me make it change everytime it is attacked?

    Here is something I use.
    PHP:
    class HealthIndicatorEngine extends Engine {
     const 
    HEARTH_SYMBOL "\xE2\x9D\xA4";
     const 
    NEW_LINE   "\n";
     
    /**
      * @param EntityDamageEvent $event
      * @priority HIGHEST
      */
     
    public function onDamage(EntityDamageEvent $event) {
      
    $e $event->getEntity();
      if(
    $e instanceof Player) {
       
    $this->updateNametag($e);
      }
     }
     
    /**
      * @param PlayerJoinEvent $event
      * @priority HIGHEST
      */
     
    public function onPlayerJoin(PlayerJoinEvent $event) {
      
    $this->updateNametag($event->getPlayer());
     }
     public function 
    entityHeal(EntityRegainHealthEvent $event) {
      if(
    $event->getEntity() instanceof Player) {
       
    $this->updateNametag($event->getEntity());
      }
     }
     public function 
    updateNametag(Player $player) : void {
      
    $currentNametag $player->getNameTag();
      if(
    strpos($currentNametagself::NEW_LINE) !== false) {
       
    $currentNametag explode(self::NEW_LINE$currentNametag)[0];
      }
      
    $health TextFormat::RED self::HEARTH_SYMBOL " " TextFormat::RESET floor($player->getHealth());
      
    $player->setNametag($currentNametag self::NEW_LINE $health);
     }
    }

    You can make task.

    PHP:
    <?php

    namespace x;

    use 
    pocketmine\scheduler\Task;
    use 
    pocketmine\Server;
    use 
    x\BossEntity// Import your boss entity file.

    class HealthTask extends Task {

      public function 
    onRun(int $currentTick) {
        foreach(
    Server::getInstance()->getLevels() as $level) {
          foreach(
    $level->getEntities() as $entity) {
            if(
    $entity instanceof BossEntity) {
              
    $entity->setNameTag(intval($entity->getHealth()) . "/" intval($entity->getMaxHealth()));

            }

          }

        }

      }

    }
    And schedule this on onEnable().

    PHP:
    $this->getScheduler()->scheduleRepeatingTask(new HealthTask(), 20);

    This code iterates over every single entity in the server just to find one that is the boss, to only change the name tag, every time the task ticks. Quite the burden, no?

    In addition to that you could also spawn an actual boss bar like from a wither to display the remaining health and modify it in onDamage or updateNametag
