Entity follows player

How can I make a entity follows a player?

 

Take a look at this
https://github.com/diamond-gold/MiniBosses/blob/master/src/MiniBosses/Boss.php#L152

 

That looks like what I want to do. But how can I use it if I want a pig follow me?

 

Just do

PHP:

$speed = 1;
$x = $player-> x - $this->x;
$y = $player-> y - $this->y;
$z = $player-> z - $this->z;
if($x ** 2 + $z ** 2 < 0.7){
$motionX = 0;
$motionZ = 0;
}else{
$diff = abs($x) + abs($z);
$motionX = $speed * 0.15 * ($x / $diff);
$motionZ = $speed * 0.15 * ($z / $diff);
}
$entity->move($motionX, $motionY, $motionZ);

 

But how can I define the entity? I spawn it with AddEntityPacket (id 5000)

 

You need to use Entity::createEntity() to be able to use this, if you just want to use packets see SetEntityMotionPacket

 

I tried this:
But it has my skin an is a human

PHP:

public function onMove(PlayerMoveEvent $e)
  {
  $player = $e->getPlayer();
 
$pk = new MovePlayerPacket();
$pk->eid = 2233;
$pk->x = $player->x;
$pk->y = $player->y;
$pk->z = $player->z;
$pk->yaw = $player->yaw;
$pk->pitch = $player->pitch;
$player->dataPacket($pk);
  }
public function spawnPet($player){
$name = $player->getName();
$text = "§l§6Test";
$pk = new AddPlayerPacket();
            $pk->eid = 2233;
            $pk->uuid = UUID::fromRandom();
            $pk->x = $player->x;
            $pk->y = $player->y;
            $pk->z = $player->z;
            $pk->speedX = 0;
            $pk->speedY = 0;
            $pk->speedZ = 0;
            $pk->yaw = 20;
            $pk->pitch = -30;
            $pk->item = Item::get(0);
    $flags = 0;
            $flags |= 1 << Entity::DATA_FLAG_CAN_SHOW_NAMETAG;
            $flags |= 1 << Entity::DATA_FLAG_ALWAYS_SHOW_NAMETAG;
            $flags |= 1 << Entity::DATA_FLAG_IMMOBILE;
            $pk->metadata = [
                Entity::DATA_FLAGS => [Entity::DATA_TYPE_LONG, $flags],
                Entity::DATA_NAMETAG => [Entity::DATA_TYPE_STRING, $text],
Entity::DATA_LEAD_HOLDER_EID => [Entity::DATA_TYPE_LONG, 12],
            ];
$player->dataPacket($pk);
}

 

I would suggest using Entity::createEntity() to spawn, because using packets is quite hard to manage the 'entities' you spawn

 

Ok. And how can I spawn a pig using this?

 

Perhaps we should write the code for you?

 

PHP:

$nbt = new CompoundTag("", [
            "Pos" => new ListTag("Pos", [
                new DoubleTag("", $pos->x),
                new DoubleTag("", $pos->y),
                new DoubleTag("", $pos->z)
            ]),
            "Motion" => new ListTag("Motion", [
                new DoubleTag("", 0),
                new DoubleTag("", 0),
                new DoubleTag("", 0)
            ]),
            "Rotation" => new ListTag("Rotation", [
                new FloatTag("", $source instanceof Location ? $pos->yaw : 0),
                new FloatTag("", $source instanceof Location ? $pos->pitch : 0)
            ]),
        ]);

$pig = Entity::createEntity("Pig",$chunk,$nbt);#$chunk can be $player->chunk
$pig->spawnToAll();


 

I found your nanny ^

 

Mh. This works. But I can't set an id?! And what is $source?

 

Does someone know how to set the Id?

 

You cant set the entityId,$source is supposed to be $pos

 

Ok. But how can I get the entity in another task or Event?

 

You save the entityId then use $level->getEntity($id) to get the entity

 

Ok. But I didn't set the Id when I spawned the entity?!

 

The id will be $entity->getId()

 

Ok... Is there a way to set the nametag of the entity?
