Packets (writes)

[KaL]

How I know what writes, what the content of them, and in what order should I put the writes in each file of serverpackets folder?

 

And how I know what is the packet type (always the 1st write of the writeImpl, writeC(0x??) packet).

[ExTrEmEDwarf]

lolscreen, please.

[Intrepid]

those are from retail sniffed packets

 

the basic structure is

 

public class name extends L2GameServerPackets
{
     private static final String packet name string = "packet name";

     // constructor with packet variables
     public name()
     {
     }

     // writeImpl() is the action of the packet
     @Override
     protected final void writeImpl()
     {
     }

     @Override
     public String getType()
    {
return packet name string;
    }
}

 

these are for server packets.

 

clientpackets use a readImpl() and runImpl() method readImpl() collect info(from client) runImpl() do the action of the clientpacket the others are similar

[KaL]

Well...I found before how is the structure and what methods each file must have. But I'm trying to find how to know the contentes of writeImpl()

 

Look at this example:

public final class FlyToLocation extends L2GameServerPacket
{
   private final L2Character _cha;
   private final int _destX, _destY, _destZ;

   public enum FlyType
   {
       THROW_UP,

   {
       _cha = cha;
       _destX = destX;
       _destY = destY;
       _destZ = destZ;
       _type = type;
   }
   
   public FlyToLocation(L2Character cha, L2Object dest, FlyType type)
   {
       this(cha, dest.getX(), dest.getY(), dest.getZ(), type);
   }
   
   /**
    * @see com.fusion.gameserver.network.serverpackets.L2GameServerPacket#getType()
    */
   @Override
   public String getType()
   {
       return "[s] 0xd4 FlyToLocation";
   }

   /**
    * @see com.fusion.gameserver.network.serverpackets.L2GameServerPacket#writeImpl()
    */
   @Override
   protected void writeImpl()
   {
       writeC(0xd4);
       writeD(_cha.getObjectId());
       writeD(_destX);
       writeD(_destY);
       writeD(_destZ);
       writeD(_cha.getX());
       writeD(_cha.getY());
       writeD(_cha.getZ());
       writeD(_type.ordinal());
   }
   
}

 

This part:

 

@Override

   protected void writeImpl()

   {

       writeC(0xd4);

       writeD(_cha.getObjectId());

       writeD(_destX);

       writeD(_destY);

       writeD(_destZ);

       writeD(_cha.getX());

       writeD(_cha.getY());

       writeD(_cha.getZ());

       writeD(_type.ordinal());

   }

 

How do I know what is the packet (content) of the first write (writeC) ? You can see it's set 0xd4, but can I get this code?

 

And the other writes? How I know what content should I put in each and in what order? If I change 1 writeD of order there, this packet won't work fine...

those from the client sniffered packets from official

The bad think is that noone plays official with phx... risk of ban

its not with phx :)

its with a simple packet sniffer :)

 

you cant play with phx on offi :D

[KaL]

Them...could you indicate any special one for me to try it? EtherDetect is a good option?

well unless you dont play on official you cant take packets and i dont know what they use exactly because i never tried to get packets from offi

[KaL]

Can't I get the packets from a L2Off server?

you mean offmod? no

[KaL]

L2Off servers, not L2j

[Emrys]

maybe WPE pro?

[Intrepid]

maybe WPE pro?

 

as i said i dont know that :)

[Emrys]

Something else, if we get an l2off server (stolen files) and capture from, there the files will be the same?

no L2Offmod servers are work with extenders they have a stolen C4 pack from ncsoft and tthey add later updates with extender which is home made not valid
