Check if item interact with entity

I'm throwing IronSword using this code

Spoiler

PHP:

public function throwSword(Player $shooter){
        $player = $shooter;
        $aimPos = $player->getDirectionVector();
        $nbt = new CompoundTag("", [
            "Pos" => new ListTag("Pos", [
                new DoubleTag("", $player->x),
                new DoubleTag("", $player->y + $player->getEyeHeight()),
                new DoubleTag("", $player->z)
            ]),
            "Motion" => new ListTag("Motion", [
                new DoubleTag("", $aimPos->x),
                new DoubleTag("", $aimPos->y),
                new DoubleTag("", $aimPos->z)
            ]),
            "Rotation" => new ListTag("Rotation", [
                new FloatTag("", $player->yaw),
                new FloatTag("", $player->pitch)
            ]),
            "Health" => new ShortTag("Health", 5),
            "Item" => new CompoundTag("Item", [
                "id" => new ShortTag("id", Item::IRON_SWORD),
                "Damage" => new ShortTag("Damage", 0),
                "Count" => new ByteTag("Count", 1),
            ]),
            "PickupDelay" => new ShortTag("PickupDelay", 0x7F),
        ]);
        $f = 1.5;
        $sword= Entity::createEntity("Item", $player->getLevel(), $nbt, $player);
        $sword->setMotion($sword->getMotion()->multiply($f));
        $sword->spawnToAll();
    }


How can I check if sword interact with Entity (Player) ?

 

You can use the EntityDamageByEntity event and get the damager's item in hand:

PHP:

public function onDamage(EntityDamageByEntityEvent $event) {
    $damager= $event->getDamager();
    $itemheld = $damager->getInventory()->getItemInHand();
    $swordids = array(267, 268, 272, 276, 283); // sword IDs
    if($damager instanceof Player) {
        if(in_array($itemheld->getId(), $swordids)) { // if damager's item held is a sword
            // do something
        }
    }
}


 

Thanks, but your code check when damager damage entity with iron sword in hand and I want to check when entity interact with THROWEN sword , so sword is not in hand

 

Are you attempting to track if the thrown item was picked up or used or what do you mean interacted with? Please specify

 

I want to check when throwen item "hit" player

 

Any idea ?

 

The InventoryItemPickupEvent does the same. You can use:

PHP:

public function onItemPickup(InventoryItemPickupEvent $event) {
    $swordids = array(267, 268, 272, 276, 283); // sword IDs
    if(in_array($event->getItem()->getId(), $swordids)) { // if player collects/touches a dropped sword
        // code
    }
}


 

It's bad idea because player can pickup item only if it's on ground and if I throw it to player's head, player can go away before it fall on ground

 

Try to use

PHP:

foreach ($this->getServer()->getOnlinePlayers() as $player) {
            foreach ($player->getLevel()->getNearbyEntities($player->getBoundingBox()->grow(1,1,1), $player) as $entity) {
                if($entity instanceof Item) {
                    if($entity->getItem()->getId() == \pocketmine\item\Item::IRON_SWORD) {
                        // code
                    }
                }
            }
        }

 

Why not assign an NBT tag to the item that was thrown, then check if the picked up item has the tag?

 

What must i write as use pocketmine\grow or what becorse my console said pocketmine\math\AxisAlignedBB::grow() is not definied pls help

 

I think method AxisAlignedBB::grow() was changed to AxisAlignedBB::expand()
