Mobs spawning

Hi, guys! I have a problem with the mobs spawning. My code you can see

Spoiler: here

PHP:

        public function createVillager($x, $y, $z, Level $level){
        $x += 0.5;
        $z += 0.5;

        $nbt = new CompoundTag;
        $nbt->Pos = new ListTag("Pos", [
            new DoubleTag("", $x),
            new DoubleTag("", $y),
            new DoubleTag("", $z)
        ]);

        $nbt->Rotation = new ListTag("Rotation", [
            new FloatTag("", 0),
            new FloatTag("", 0)
        ]);

        $nbt->Health = new ShortTag("Health", 20);
        $nbt->CustomName = new StringTag("CustomName", "§3Эдвард §7- §eКвестер");
        $nbt->CustomNameVisible = new ByteTag("CustomNameVisible", 1);

        $level->loadChunk($x >> 4, $z >> 4);

        $villager = Entity::createEntity("Villager", $level->getChunk($x >> 4, $y >> 4), $nbt);
        $villager->spawnToAll();
        }

So, there is a

        $villager->spawnToAll();
        }
    }

?>

 

i think you forgot to put use
pocketmine\level\format\FullChunk;

 

Why ist there a $y??

PHP:

        $villager = Entity::createEntity("Villager", $level->getChunk($x >> 4, $y >> 4), $nbt);  

 

Its checking the x/y position

 

Because it isn't a parameter in the Level::getChunks() function.
