How I spawn a simple npc?

Try this code

PHP:

public function spawnNPC(Player $player)  {
                $nbt = new CompoundTag;
                $nbt->Pos = new ListTag("Pos", [
                    new DoubleTag("", $player->getX()),
                    new DoubleTag("", $player->getY()),
                    new DoubleTag("", $player->getZ())
                ]);
                $nbt->Motion = new ListTag("Motion", [
                    new DoubleTag("", 0),
                    new DoubleTag("", 0),
                    new DoubleTag("", 0)
                ]);
                $nbt->Rotation = new ListTag("Rotation", [
                    new FloatTag("", $player->getYaw()),
                    new FloatTag("", $player->getPitch())
                ]);
                $nbt->Health = new ShortTag("Health", 20);
                $nbt->Skin = new CompoundTag("Skin", [
                    "Data" => new StringTag("Data", $player->getSkin()->getSkinData()),
                    "Name" => new StringTag("Name", $player->getSkin()->getSkinId())]);

                $human = new Human($player->getLevel(), $nbt);
                $human->setNameTag($player->getName());
                $human->setNameTagVisible(false);
                $human->spawnTo($player);
}

 

this works too, now im working definitely on this, i'm adding a cmd to this using EntityDamageEvent

 

Use this:

PHP:

$this->spawnNPC($player)
