SteamNetworkLib

A streamlined Steam networking library for MelonLoader mods - simplify lobby management, data sync, and P2P communication

What is SteamNetworkLib?

SteamNetworkLib is a streamlined, object-oriented Steam networking library designed specifically for MelonLoader mods. This library dramatically simplifies Steam lobby management, data synchronization, and P2P communication compared to using Steamworks. NET directly.

Perfect for mod developers who want to add multiplayer features without wrestling with the complexity of Steamworks. NET!

• []Lobby Management: Create/join lobbies with async/await support, automatic member tracking, and Steam overlay integration[/]

  []Data Synchronization: Global lobby data and per-player member data with automatic caching and event-driven updates[/]

  []P2P Communication: Type-safe message system with automatic serialization, broadcast or direct messaging, and built-in message types[/]

• []Simplified API: Object-oriented design that's much easier to work with than raw Steamworks. NET[/]

  []Event-Driven: Automatic notifications when lobbies change, members join/leave, or data updates[/]

  []Type-Safe Messages: Built-in serialization for common message types (Text, DataSync, DataRequest, FileTransfer) plus support for custom messages[/]

  []MelonLoader Optimized: No complex setup, automatic resource cleanup, mod compatibility checking, and robust error handling [/]

  Installation

  This is a library for mod developers, not an end-user mod. To use it in your mod:

  • []Add the Mono SteamNetworkLib as a reference to your mod project
    Note: When running the game, users should still have the correct Mono/Il2Cpp dll installed.[/]

    []Build your mod, using the library for networking[/]

    []Direct users to install SteamNetworkLib along with your mod[/]

  Installing the library manually when a mod you are using requires it:
  • []Download the appropriate Il2Cpp/Mono build for your game branch from the "Files" tab[/]

    []Open the zip and drag the "UserLibs" folder into your Schedule 1 game installation folder[/]

    Requirements

    . NET Framework 4. 7. 2+ or . NET 6. 0+
    Steam
