InteractPacket with NPC

Hello,
I spawn a fake player with Player AddPacket, the problem is that I can not do any action when the player clicks on the entity! I try EntityDamageEvent and PacketInteract, PacketInteract works but it is when we fly over the entity and not when clicking!

Thanks for the help.


»» CODE FOR SPAWN:

PHP:

public function spawn(Player $player, array $infos) {
        $pk = new AddPlayerPacket();
        $pk->eid = (int)$infos['id'];
        $pk->uuid = UUID::fromRandom();
        $pk->entityUniqueId = (int)$infos['id'];
        $pk->entityRuntimeId =  (int)$infos['id'];
        $pk->username = $infos['name'];
                $pk->skin = clone $player->getSkin();
        $pk->position = new Vector3($infos['x'], $infos['ya'], $infos['z']);
        $pk->x = $infos['x'];
        $pk->y = $infos['ya'] + 1;
        $pk->z = $infos['z'];
        $pk->item = Item::get($infos['item'], $infos['meta'], 1);
        $pk->speedX = 0;
        $pk->speedY = 0;
        $pk->speedZ = 0;
        $pk->yaw = $infos["yaw"];
        $pk->pitch = $infos["pitch"];
        $pk->metadata = [
            Entity::DATA_FLAGS => [Entity::DATA_TYPE_BYTE, 0 << Entity::DATA_FLAG_INVISIBLE],
            Entity::DATA_NAMETAG => [Entity::DATA_TYPE_STRING, $infos['name']],
            Entity::DATA_FLAG_CAN_SHOW_NAMETAG => [Entity::DATA_TYPE_BYTE, 1],
            Entity::DATA_FLAG_NO_AI => [Entity::DATA_TYPE_BYTE, 1],
            Entity::DATA_LEAD_HOLDER_EID => [Entity::DATA_TYPE_LONG, -1],
            Entity::DATA_FLAG_LEASHED => [Entity::DATA_TYPE_BYTE, 0]
        ];
        $player->dataPacket($pk);
    }


 

The problem is that you spawn the Entity on client side only and server doesn't keep it's "copy" of the entity on server side so no events/interactions can be made. This is basic game server logic. Take a look how Slapper does it (does Slapper still exist?).

Hint: extend human class

Edit: I found it this and also this

 

use inventory transaction packet instead of interactpacket

 

What it has to do with Inventory Transaction?

 

https://github.com/pmmp/PocketMine-...e/protocol/InventoryTransactionPacket.php#L48

 

How ?

PHP:

public function onReceive(DataPacketReceiveEvent $event)
    {
        $pk = $event->getPacket();
        if($pk instanceof InteractPacket) {
            if($pk->action instanceof InventoryTransactionPacket ) {
            }
         }
    }


 

Look how pocketmine does it
https://github.com/pmmp/PocketMine-MP/blob/master/src/pocketmine/Player.php#2269

 

The mojang people stuffed almost everything into InventoryTransactionPacket including Player->Entity interactions.

Check if $pk is instanceof InventoryTransactionPacket and $pk->transactionType is InventoryTransactionPacket::USE_ITEM_ON_ENTITY_INTERACT. If so, then $pk->trData->entityRuntimeId will return the packet entity's entityRuntimeId.

Anyway, what's wrong in using pocketmine's Entity class?

 

That's what I said. Human is instance of Entity after all.

Might seem funny to us, but makes sense for them.
