Solved Decode BatchPacket

Hello. I wrote a simple proxy that read packets from the server and the client, but how decode batch?

PHP:

if(($packet = Pool::getPacketFromPool(ord($buffer{0}))) !== null){
   $packet->buffer = $buffer;
   $packet->decode();
   if($packet instanceof DATA_PACKET_4){
      foreach($packet->packets as $pk){
         $id = ord($pk->buffer{0});
         if($id !== 0x10 && $id !== 0x03){
            $dataPacket = PacketPool::getPacket($pk->buffer);
            if($dataPacket instanceof BatchPacket){
               $dataPacket->decode();
               var_dump($dataPacket); //need decode batch here
            }
         }
      }
   }
}


 

Use this to get every packet in a BatchPacket:

PHP:

if($dataPacket instanceof BatchPacket){
    $dataPacket->decode();
    foreach($dataPacket->getPackets() as $buf){
        $pk = PacketPool::getPacketById(ord($buf{0}));
        if(!$pk->canBeBatched()){
            continue;
        }
        $pk->setBuffer($buf, 1);
        //Now handle $pk like a normal Packet
    }
}


PS: I'm pretty bad at understanding the networking in pmmp, so this might be wrong.

 

Warning: zlib_decode(): data error in BatchPacket.php on line 59

 

welp, maybe you got an invalid packet?

 

Maybe. I got this

Code:

Warning: zlib_decode(): data error in \BatchPacket.php on line 59

or this

Code:

object(Generator)#144 (0) {
}

when use

PHP:

var_dump($dataPacket->getPackets());
