How do I make a player sit with DataPacket?

How do I make a player sit.? Packets have been changed in PocketMine and old chair plugins don't work. I found this edit of a plugin by Jasonwynn on the forums which is probably my best hope of fixing it:

PHP:

<?php
namespace maru;

use pocketmine\entity\Entity;
use pocketmine\Server;


use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
use pocketmine\event\server\DataPacketReceiveEvent;
use pocketmine\network\mcpe\protocol\AddEntityPacket;
use pocketmine\event\player\PlayerInteractEvent;
use pocketmine\network\mcpe\protocol\ProtocolInfo;
use pocketmine\block\Stair;
use pocketmine\network\mcpe\protocol\RemoveEntityPacket;
use pocketmine\network\mcpe\protocol\SetEntityLinkPacket;
use pocketmine\math\Vector3;
use pocketmine\network\mcpe\protocol\types\EntityLink;

class PmChair extends PluginBase implements Listener{
    public $counter = [];
    public $count = 0;
    public function onEnable(){
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->count = 10000;

    }
    public function onPacketReceived(DataPacketReceiveEvent $event){
        $pk = $event->getPacket();
        switch($pk::NETWORK_ID){
            case ProtocolInfo::PLAYER_ACTION_PACKET;
                $player = $event->getPlayer();
                if(isset($this->counter[$player->getName()])){
                    if($pk->action === 8){$ppk = new SetEntityLinkPacket();
                        $ppk->from = $this->counter[$player->getName()];
                        $ppk->to = 0;
                        $ppk->type = 0;
                        $player->dataPacket($ppk);
                        $pkc = new SetEntityLinkPacket();
                        $pkc->from = $this->counter[$player->getName()];
                        $pkc->to = $player->getId();
                        $pkc->type = 0;

                        Server::getInstance()->broadcastPacket($ps,$pkc);

                        Server::getInstance()->broadcastPacket($ps,$pk0);
                        unset($this->counter[$player->getName()]);
                    }
                }
        }
    }

    public function onTouch(PlayerInteractEvent $event){
        if($event->getBlock()->getID() === 53){
            $player = $event->getPlayer();
            $pk = new AddEntityPacket();
            $this->count = $this->count + 1;
            $pk->entityRuntimeId=$this->count;
            $pk->type = 86;
            $pk->motion = new Vector3();
            $block = $event->getBlock ();
            if ($block instanceof Stair) {
                $pk->position = $block->asVector3()->add(0.5, 1.5, 0.5);
                $pk->speedX = 0;
                $pk->speedY = 0;

                $ppk->from = $this->count;
                $ppk->to = 0;
                $ppk->type = 2;$player->dataPacket($ppk);
                $pkc = new SetEntityLinkPacket();
                $pkc->from = $this->count;

This had a couple of errors which I fixed but the big issue with this is something to do with putEntityLink ?

Code:

[22:34:20] [Server thread/CRITICAL]: Could not pass event 'pocketmine\event\player\PlayerInteractEvent' to 'PmChair v1.3': Argument 1 passed to pocketmine\network\mcpe\protocol\DataPacket::putEntityLink() must be an instance of pocketmine\network\mcpe\protocol\types\EntityLink, null given, called in phar://C:/Users/Admin/Creative Cloud Files/Desktop/Server/Server - DEV/PocketMine-MP.phar/src/pocketmine/network/mcpe/protocol/SetEntityLinkPacket.php on line 43 on maru\PmChair

When the player taps block ID 53 it needs to sit them on it, please help me do this

 

PHP:


public function onClick(PlayerInteractEvent $e){
   if($e->getItem()->getId() !== 280 || $e->getAction() !== $e::RIGHT_CLICK_BLOCK){
      return;
   }
   $block = $e->getBlock();
   $player = $e->getPlayer();
   $player->setMotion(new Vector3(0, 0.2, 0));

   $add = new AddEntityPacket;
   $add->entityRuntimeId = 666;
   $add->type = 95;
   $add->position = new Vector3($block->x - 0.3, $block->y + 1.7, $block->z + 0.3);
   $player->dataPacket($add);

   $link = new SetEntityLinkPacket;
   $link->link = [666, $player->getId(), 1, 1];
   $player->dataPacket($link);
}


 

Thanks!
But why does it get block 280 at the start?

 

How do I make it allow only being able to tap the block 53 to sit on it
this..?

PHP:

    public function onTouch(PlayerInteractEvent $event){
        if($event->getBlock()->getID() === 53){
              $block = $event->getBlock();
              $player = $event->getPlayer();
              $player->setMotion(new Vector3(0, 0.2, 0));
            
              $add = new AddEntityPacket;
              $add->entityRuntimeId = 666;
              $add->type = 95;
              $add->position = new Vector3($block->x - 0.5, $block->y + 1.5, $block->z + 0.5);
              $player->dataPacket($add);

              $link = new SetEntityLinkPacket;
              $link->link = [666, $player->getId(), 1, 1];
              $player->dataPacket($link);
        }
    }
    

 

oh it works but is there a way to remove the popup that appears when the player sits on the chair? "action.hint.exit.area_effect_cloud"

 

This is client side message
