        $entity->spawnToAll();
        $nbt->TileID = new IntTag("TileID", 35);
        $nbt->Data = new ByteTag("Data", mt_rand(1, 15));
        $gadget = Entity::createEntity("entita", $player->getLevel(), $nbt);
        $gadget->spawnToAll();

Please help me

 

Use $entity = new pocketmine\entity\Human(Level $level, CompoundTag $nbt); instead of Entity::createEntity
