Help!!!

How can do I if a player is tapped they get a op ban etc commands

 

Your title says “Help!!!” and you ask a question like that ;-;
Any previous attempts?
Rename your title to something more descriptive

 

If you’re trying to give the player OP when he/she gets hit by another player, try this code:

PHP:

use pocketmine\event\entity\EntityDamageByEntityEvent; // don’t forget to add the event’s class (and register the Listener)

public function onEntityDamage(EntityDamageByEntityEvent $event) {
    $damager = $event->getDamager();
    $entity = $event->getEntity();
    if($damager instanceof Player && $entity instanceof Player) { // if damager and hit entity are players
        $entity->setOp(); // gives the hit player OP
    }
}
