Is there away to make Throwing Sword?

Is there away making throwing sword making murder mystery plugin!

 

sure, by spawning an ArmorStand, making it invisible and give it a sword.

 

I do not know if it will work.

PHP:

/**
     * @param Player $shooter
     */
    public function throwSword(Player $player) {
        $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),
        ]);
        $sword = Entity::createEntity("Item", $player->getLevel(), $nbt, $player);
        $sword->setMotion($sword->getMotion()->multiply(1.5));
        $sword->spawnToAll();
        $player->getInventory()->setItemInHand(Item::get(Item::AIR));
    }

 

Ehh, you can cut down on a lot of code (repetition) there. Using Item entity may not be ideal, try a custom ArmorStand class like @Thunder33345 said.

PHP:

/** @var Player $player */
$nbt = Entity::createBaseNBT($player->add(0, $player->getEyeHeight(), 0), $player->getDirectionVector(), $player->yaw, $player->pitch);
$sword = Entity::createEntity("ThrowingKnife", $player->getLevel(), $nbt, $player);
$sword->setMotion($sword->getMotion()->multiply(1.5));
$sword->spawnToAll();


The ThrowingKnife class could extend the Projectile class like so.

PHP:

class ThrowingKnife extends Projectile{
    public const NETWORK_ID = self::ARMOR_STAND;
    //dont forget the $width and $height

    protected function sendSpawnPacket(Player $player) : void{
        parent::sendSpawnPacket($player);
        //send MobEquipmentPacket for Iron Sword
    }
}


 

Ah, yes. The pose #8 with yaw = relative yaw - 75 seems suitable for a throwing knife. I think you'll need to lock the rotation.

PHP:

$nbt = Entity::createBaseNBT(
    $player->add(0, $player->getEyeHeight(), 0),
    $player->getDirectionVector(),
    $player->yaw - 75,//makes the sword point straight, instead of towards the right
    $player->pitch
);

//initEntity()
$sword->getDataPropertyManager()->setByte(Entity::DATA_ARMOR_STAND_POSE_INDEX, 8);


 

Can we despawn the sword?

Because it’s a entity

 

What you mean?

 

$entity->kill()

 

$entity->close() should do
P.S. Use $entity->flagForDespawn() now that it exists.

 

or $entity->flagForDespawn()

 

Does this still works? For lastest pmmp?

 

Sure, it should.
