here is some structures of packets, i don't find any documented .If some are not correct please add the correct structures.
Code: Select all

00 A0 C1 00
UInt32 = flag Id
Are you sure about "UInt32 = flag Id" ?
Shouldn't it be 0x00A0C100 then?
It also might be just an INT8/CHAR prepended by two bytes, which could be the packet size in bytes (excluding the first fixed 3 bytes for packet size and id flag.
See, 0x00A0 = 160
Exclude the 2 bytes for the packet size and the 1 byte for ID, makes 3 bytes from the 163 bytes of data, you get 160 bytes.
Check it and you will see it does make more sense. But its just blindly guessing. Thats does match and is typical for packaging. YOu want to know the length of the packet and what type of packet.
SO I would say:
UInt16 = Packet CONTENT size
UInt8 = id flag
*edit*
found the corresponding code (not for genereting the package directly, but which proves my idea):
https://github.com/WarEmu/WarEmu/blob/u ... PServer.cs
see this:
Code: Select all
public TCPServer()
: base()
{
PacketOut.SizeLen = sizeof(UInt16);
PacketOut.OpcodeInLen = false;
PacketOut.SizeInLen = false;
PacketOut.OpcodeReverse = false;
PacketOut.SizeReverse = false;
PacketOut.Struct = PackStruct.SizeAndOpcode;
}
you see? SizeLen UInt16 (to be precice sizeof the type UInt16, should it be for any reason not 16bit) and also OpcodeInLen and SizeInLen are both false, so they are not included in the length, which agains matches to what i said

00 A0 C1 C1 is the opcode = 0xC1) F_OBJECTIVE_INFO ignore theses. 00 A0 C1
00 00 00 E4 (E4 = flag id ) If you write the structure to use i will try it, and let you know if it works.

this is currently in the code i dont think it works yet though
Code: Select all
PacketOut Out = new PacketOut((byte)Opcodes.F_OBJECTIVE_INFO);
Out.WriteUInt32(Info.Entry);
Out.WriteByte(0); // Type
Out.WriteByte(Info.Type);
Out.WriteByte(Info.Type); // Forteresse, rien du tout ,etc
Out.WriteUInt16(0);
Out.WritePascalString(Info.Name);
Out.WriteByte(1);
Out.WriteUInt16(0); // Time in second
Out.WriteUInt32(0x034B0201);
Out.WriteByte(1);
Out.WriteByte(0);
Out.WriteByte(1);
Out.WriteUInt16(0);
Out.WriteByte(0);
Out.WritePascalString(Stage.Objectives.First().Objective.Objective);
Out.WriteByte(0);
Out.WriteByte(0);
Out.WriteStringToZero(Stage.StageName);
Out.WritePascalString(Stage.Objectives.First().Objective.Description);
Out.WriteUInt16(0);
Out.WriteUInt16(0x012C);
Out.WriteUInt32(0x9E);
Out.WriteUInt32(0);
Out.WriteByte(0x48);
Out.WriteUInt32(0);
//Out.WriteHexStringBytes(Str.Replace(" ", string.Empty));
Plr.SendPacket(Out);

This is for public quest Stages,which is different packet structure. It's were you walk to The Nordland XL flag,and it displays The Nordland XL at top of right hand side of game ,in yellow.I will mess around with it and see if i can find it

Can you pm me your recent PQuest_Objective.cs.I will have a look at it,and see what i can do.
