Caution
This project is incomplete and not ready for general use.
In Valve games, the Game Coordinator (GC) is a backend service most notably responsible for matchmaking and inventory management (like loadouts and skins). This project redirects the GC traffic to a custom, in-process implementation.
While it's still possible to connect CS:GO to CS2's GC by spoofing the version number, this may break in the future if Valve updates the GC protocol. This project aims to restore most GC-related functionality without relying on a centralized server.
- Editable inventory (
inventory.txt) - Live inventory updates while the game is running
- Item equipping and loadout updates
- Opening cases, sticker capsules, patch packs, graffiti boxes, music kit boxes and souvenir packages
- Souvenir item generation
- Stickers and patches
- Name tags
- Graffiti support
- Music kits
- Weapon StatTrak support
- Music kit StatTrak support, including round MVP count propagation
- Storage Units
- StatTrak Swaps
- Trade ups
- In-game store purchases
- Read-only inventory consistency diagnostics
- Source RCON-compatible local control interface
- Parameterized RCON item creation for paint kits, wear, seed, StatTrak, music kits, sprays, stickers and custom names
- Works without full Steam API emulation
- Full Windows, Linux and macOS support
- Functional lobbies
- Dedicated server support
- Functional server browser (only shows csgo_gc servers by default)
- Networking using Steam's P2P interface
- More validation and polish for edge-case inventory operations
- Tooling around live inventory editing
I'm still looking for the full CS:GO Item Schema. If you have a relatively recent copy of it and are willing to share it, let me know!
- Matchmaking (can't be implemented without a centralized server)
- Download CS:GO from Steam
- Download the latest release for your platform from the releases page
- Navigate to the game's installation directory
- Back up your existing launcher executables as they'll be overwritten (i.e. csgo.exe, srcds.exe, csgo_linux64, etc.)
- Extract the contents of the downloaded archive to your game directory, replace the executables when prompted
- Launch the game. If you get the annoying VAC message box, launch the game with the -steam argument
- macOS users: The release binaries are not notarized, so if you're using them, you'll have to deal with that somehow
Inventory can still be edited offline through inventory.txt. For manual editing, there is a guide made by someone else here.
The local RCON interface can also create and remove items while the game is running. This is intended for scripts and GUI editors that want to avoid the old edit-file-and-restart workflow.
See Souvenir Packages for tournament attributes, examples
for different Major eras, manual inventory.txt editing, and an explanation of
how package loot lists differ from souvenir sticker metadata.
See csgo_gc/config.txt for available options.
Supplemental server-only loot lists that are missing from the client schema are
stored in csgo_gc/gc_loot_lists.txt. An external
loot list can include an item_sets block to reuse collections from
items_game.txt without duplicating every item in the collection.
RCON is disabled by default and binds to localhost with the default configuration; the actual listen address is controlled by bind_address. It uses the Source RCON binary protocol, so existing Source RCON clients can be used.
See rcon.md for protocol details, configuration, supported parameters and error formats.
Requirements:
- Git
- CMake 3.20 or newer
- C++ compiler with C++17 support (VS 2017 or later, Clang 5 or later, GCC 7 or later)
The top-level CMake project downloads protobuf, cryptopp-cmake and funchook through FetchContent during configure.
The game is 32-bit on Windows so you need to build as 32-bit:
cmake -A Win32 -B build
cmake --build build --config Release --target csgo_gcLinux dedicated servers are also 32-bit:
cmake -DCMAKE_C_FLAGS=-m32 -DCMAKE_CXX_FLAGS=-m32 -DCMAKE_ASM_FLAGS=-m32 -B build
cmake --build build --target csgo_gcOn macOS, you need to build for x86_64 instead of arm64:
cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 -DFUNCHOOK_CPU=x86 -B build
cmake --build build --target csgo_gcFor Linux clients you don't have to specify any additional options.
For a full launcher package build, also build the launcher targets:
cmake --build build --config Release --target csgo srcds csgo_gcThis project is licensed under the 2-Clause BSD License. See LICENSE.md for details.
