Custom Packets

Hey, Im trying to make some custom packets, but I have no idea what to add into the encode() or decode() functions.

Here is a basic packet template:

PHP:

class PlayerListPacket extends DataPacket {

   const NETWORK_ID = 0xc3;

   public function pid(){
      return 0xc3;
   }

   public function decode(){ }

   public function encode(){
      $this->buffer = \chr(self::NETWORK_ID); $this->offset = 0;;
   }

}


Now, at the moment, the encode makes the client freeze. Im not too sure how it is formatted as each type of data value is encoded in a strange way.

Here is an example of the encode function in the AddPlayerPacket:

PHP:

public function encode(){

   $this->buffer = \chr(self::NETWORK_ID); $this->offset = 0;;
   $this->buffer .= Binary::writeLong($this->clientID);
   $this->putString($this->username);
   $this->buffer .= Binary::writeLong($this->eid);
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->x) : \strrev(\pack("f", $this->x)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->y) : \strrev(\pack("f", $this->y)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->z) : \strrev(\pack("f", $this->z)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->speedX) : \strrev(\pack("f", $this->speedX)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->speedY) : \strrev(\pack("f", $this->speedY)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->speedZ) : \strrev(\pack("f", $this->speedZ)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->yaw) : \strrev(\pack("f", $this->yaw)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->yaw) : \strrev(\pack("f", $this->yaw)));
   $this->buffer .= (\ENDIANNESS === 0 ? \pack("f", $this->pitch) : \strrev(\pack("f", $this->pitch)));
   $this->buffer .= \pack("n", $this->item);$this->buffer .= \pack("n", $this->meta);
   $this->buffer .=    \chr($this->slim ? 1 : 0);
   $this->putString($this->skin);
   $meta = Binary::writeMetadata($this->metadata);
   $this->buffer .= $meta;
}


Any ideas?

I don't understand a single line XD

Don't use code decompiled from phar. Use code from PocketMine source. That makes more sense.

i did use it from the pocketmine source. Look for yourself

This is what I meant by PocketMine source. https://github.com/PocketMine/Pocke...cketmine/network/protocol/AddPlayerPacket.php This is the unprocessed version of PocketMine.

ah, thats really helpful, thanks

(I was getting the classes from my IDE, so i thought it would have been an unprocessed version but it clearly isnt xD)
