How I spawn a simple npc?

Hi everyone, I'm making a server core with multiple classes, doing them I'm learning pmmp API at same time, I know php and a little php OOP, but I need some help because there are things that I don't understand, how do I spawn a simple npc in my lobby with custom pos? I watched other threads but were useless for them. Thx for you help, I appreciate it!

 

Look at Slapper Plugin

 

It's useless when u want to make only one core ._.

 

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);
}


 

It's useless to make core when you can use slapper

 

Irrelevant

 

Why? If he don't know to use search bar, it's better for him to use slapper

 

He asked a question, if you know code then its not hard to post how to spawn a NPC.

 

why dont u post how to spawn an NPC then not talk trash to these people

 

PHP:

$pk = new AddPlayerPacket();
    $pk->entityRuntimeId = Entity::$entityCount++;
    $pk->uuid = UUID::fromRandom();
    $pk->username = "NPC";
    $pk->position = $position;
    $pk->item = ItemFactory::get(Item::AIR, 0, 0);
    self::$plugin->getServer()->broadcastPacket([$player], $pk);

1. Not a real entity so its less lag
2. Here. I posted code

 

Thanks, it seems working, i edited pmmp adding nbt, and fixed few things, it seems working but it gives this error related at the entity skin: InvalidStateException: "Human must have a valid skin set". So i think the $player->getSkin()->getSkinData(); is not working properly, any help? Thanks.

 

How are you setting the skin

 

i used GamakCZ method, so should be this:
$nbt->Skin = new CompoundTag("Skin", [
"Data" => new StringTag("Data", $player->getSkin()->getSkinData()),
"Name" => new StringTag("Name", $player->getSkin()->getSkinId())]);

 

Do u have Player $player

Btw what’s err

and yes, is registered:
$player = $e->getPlayer();

 

Did u have $player = $ev->getPlayer()

 

Yes i have It!

 

with this code, you cant set skin with your method. Use a packet to set skin

 

thanks, now is working, but if i want to add it a function onTouch() and a custom skin, what should i have to do? i have to store skin or with my method it auto change evry player join

 

Code that @Daniktheboss gave you register entity only to the client, you have to register it in server if you want to check touching it etc without DataPacketReceiveEvent.
