     $event->setCancelled(false);
     $player->setHealth(20);
      $damager = $event->getDamager()->getPlayer();
      $x = $damager->getDirectionVector()->getX();
      $z = $damager->getDirectionVector()->getZ();
     for($i = 0; $i <= 750 ; $i++){
      $player->knockBack($player, $x , $z, 0.5);
     }
    }else{
     $event->setCancelled(true);
    }
   }
  }
 }


help please !
thank you in advance

 

\pocketmine\Player->knockBack() does not exist
why not just use:
https://github.com/pmmp/PocketMine-...vent/entity/EntityDamageByEntityEvent.php#L75

PHP:

public function onDamage(EntityDamageEvent $event){
  if($event->getEntity() instanceof Player){
   $player = $event->getEntity()->getPlayer();
   $level = $player->getLevel()->getName();
   if($event Instanceof EntityDamageByEntityEvent){
    $item = $event->getDamager()->getInventory()->getItemInHand()->getId();
    if($item == Item::BLAZE_ROD){
     $player->setHealth(20);
     $event->setKnockBack(10);
    }else{
     $event->setCancelled(true);
    }
   }
  }
 }


 

thx for your answer but setKnockBack is too strong, the player fly away...

 

You can edit it!

PHP:

$event->setKnockBack(2); // Editable

 

even setKnockBack(2) is too strong, the player flies high.

 

then lower it. Seriously
you can also use floating point values (e.g. 1.5)

 

i would like the player KnockBack at the same height, in a straight line.

 

well, that's something different.
For that you an use setMotion

PHP:

public function onDamage(EntityDamageEvent $event){
  if($event->getEntity() instanceof Player){
   $player = $event->getEntity()->getPlayer();
   $level = $player->getLevel()->getName();
   if($event Instanceof EntityDamageByEntityEvent){
    $item = $event->getDamager()->getInventory()->getItemInHand()->getId();
    if($item == Item::BLAZE_ROD){
      $player->setHealth(20);
      $damager = $event->getDamager()->getPlayer();
      $dirVec = $damager->getDirectionVector()->getX();
       $damager->setMotion(new Vector3($dirVec->getX(), 0.1, $dirVec->getZ());
    }else{
     $event->setCancelled(true);
    }
   }
  }
 }


 

thank you !

 

Whenever you're checking whether an item's ID or item's damage is so and so, use the identity operator. Equality operator is useless as ID and damage always return int, not an integer in a string.

PHP:

if($item === Item::BLAZE_ROD)


 

i didnt want to create a new thread so. I have a working plugin like this. But when I hit the player the actual knockback of the player doesnt work. It works in a way where it moves the player only a certain direction even though you hit from anyside. Any help? I saw the function
Public function knockback in Living.php but idk how that works pla help

 

well, you can try to use setKnockBack, as quoted above

 

I have a wroking plugin using setKnockback but the reason is I want to change the amount of height they get off the ground when they get hit but keep the default knockback goind sideways and backwards

 

that should work with this, because it uses the DirectionVector of the attack. Just modify 0.1 for the height.
