This page aims to explain how packets are handled in terms of structure and functionality Properties A packet has several data properties, them being game and networking information as: Header - A byte that identifies the packet Data - The data that is being sent/received Sequence - A byte that signs if the packet is sequenced On sending/receiving packets may be encrypted, check Network Encryption for more information Structure The packets have two different structures, constant and dynamic The goals of each type is predefined by the type of data handled Note: The sequence byte is always the last byte in a packet, no matter the structure and its optional Constant The constant packet structure follows the expected order of data: Structure Type Size (bytes) Description Header 1 Byte The number identifier of the packet Data X Bytes The expected constant data values Sequence 1 Byte The sequence value which defines if this packet is sequenced (optional) Dynamic The dynamic packet structure follows the expected order of data: Structure Type Size (bytes) Description Header 1 Byte The number identifier of the packet Size 2 Bytes The size of the entire packet, Header + Size + Data (excluding sequence) Data ? Bytes The expected dynamic data values Sequence 1 Byte The sequence value which defines if this packet is sequenced (optional) Flow/Direction The packets have different type denominations of directions regarding from who to who they are sent: CG(Client Game) - Client to Server GC(Game Client) - Server to Client GG(Game Game) - Server to Server GD(Game Database - Server to Database DG(Database Game) - Database to Server Note: The meaning of 'Server' in this case is a server core such authentication/game core and the meaning of 'Database' is the database core Known Packets Here is a list table of the known packets and its directions: Client to Server Client to Game - CG Header Identification - Byte (Hex) Description Sequenced Structure 1 (0x01) Holds account credentials to perform a login True #CG Packet Login 2 (0x02) Holds target, attack and cube information to perform several actions True #CG Packet Attack 3 (0x03) Holds length and type of a chat string to perform a chat command True #CG Packet Chat 4 (0x04) Holds information to create a new character True #CG Packet Player Create 5 (0x05) Holds an index and a key to delete an existing character True #CG Packet Player Destroy 6 (0x06) Holds an index to select an existing character True #CG Packet Player Select 7 (0x07) Holds movement, positional and duration information to move the main character True #CG Packet Player Move 8 (0x08) Holds identification and positional information of entities to perform synchronization True #CG Packet Sync Position 9 (0x09) Holds account credentials and character index to perform a direct entrance in the game True #CG Packet Direct Enter 10 (0xA) Signals the server to enter the game world True #CG Packet Enter Game 11 (0xB) Holds inventory position to perform an item use True #CG Packet Item Use 12 (0xC) Holds inventory position and Elk(game currency) to perform an item/elk drop in the game world True #CG Packet Item Drop 13 (0xD) Holds source, target position and count to perform a item move inside the inventory True #CG Packet Item Move 15 (0xF) Holds position of game world item to perform a pickup True #CG Packet Pickup 16 (0x10) Holds position and quickslot information to perform a quickslot addition True #CG Packet Quickslot Add 17 (0x11) Holds position to perform a quickslot removal True #CG Packet Quickslot Delete 18 (0x12) Holds source and target position to perform a quickslot swap True #CG Packet Quickslot Swap 19 (0x13) Holds a chat string to perform a whisper action True #CG Packet Whisper 20 (0x14) Holds inventory position and Gold(game currency) to perform an item/gold drop in the game world True #CG Packet Item Drop 2 26 (0x1A) Holds entity information to perform a click action True #CG Packet On Click 28 (0x1C) Holds character position information (undefined reason) True #CG Packet Character Position 29 (0x1D) Holds answer information for a script/quest True #CG Packet Script Answer 30 (0x1E) Holds an input string for a quest response True #CG Packet Quest Input String 31 (0x1F) Holds answer information for a quest confirmation True #CG Packet Quest Confirm

Before starting to work on your server you need to understand some important things: The development and administration IS NOT an easy task. You need some fundamental knowledge about computers and servers. You will work with copyrighted/proprietary material. Depending on which country you come from, this may violate applicable laws. You can get help from the community but don't expect too much. Use Google (or other search engines) before you ask something that is actually easy to find out. This wiki will only help you in case you want to understand the development of Metin2. Note: General knowledge of computers and servers and even programming languages is not included in this wiki. But it is required to work on specific things of a Metin2 Server. That's the part we want you to use Google for! Roles and needed Skills Server Administrator Expert knowledge of the system you are running the server, which includes, for example, firewall, package managing, services. Advanced knowledge of the database storage server. (Required for diagnose issues on the MySQL part) Server Developer Basic knowledge of the FreeBSD operative system and its API. Advanced knowledge of the Client and Server protocol/structure. (which includes Unix sockets) Expert knowledge of the C and C++ programming language. Advanced knowledge of the GNU makefile syntax and the GNU C Compiler or CLang Client Developer Basic knowledge of the Windows operative system and its API. Basic knowledge of the Client and Server protocol/structure. (Metin2 already wraps all the socket calls) Expert knowledge of the C and C++ programming language. Advanced knowledge of the Python 2.7 programming language. (required for making internal changes in the python part of the game) Advanced knowledge of the Visual Studio IDE. Tools Developer (e.g. WorldEditor, Autopatcher) Basic knowledge of transfer protocols (this may vary on the tool you are developing) Basic knowledge of managing file system and webhosting (this may vary on the tool you are developing) Advanced knowledge of File Formats Basic knowledge of PHP (this may vary on which language you want to use for the scripts) Advanced knowledge of C# (this may vary on which language you want to use for the tool) Quest Developer Expert knowledge of LUA 5.0 programming language. All available quest commands and how to use them 2D / Graphic Artist xxx 3D / Model Artist xxx

M2 uses a lot of third party libraries. For each segment there is at least one that handles correct functionality. It requires a lot of programming knowledge to implement, edit or replace any of these. Please be aware of some of the libraries are proprietal and you have to own a license to use them for commercial usage (depends on license type). To learn more about 3rd party software please use Google, as this wiki is only M2 related.

Tar package file is a file format used to compress Metin1 data files. NOTE: The files are encrypted with an unknown format. 
 
 4 bytes in black, only present at the beginning: Number of file entries included. One or more file entry File Entry 32 bytes in green: Filename (Encoded in Windows-949). 4 bytes in purple: Offset of the file (relative to the stat of the tar file)-. 4 bytes in blue: Size of the file. Bytes in grey: beginning of a new entry.
