SteamNetworkLib Mono

SteamNetworkLib

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.

• Automatic member tracking with join/leave events
• Steam overlay integration for invites

📊 Data Synchronization

• Member Data: Per-player data visible to everyone
• Automatic caching and change detection
• Event-driven updates when data changes

🌐 P2P Communication

• Type-safe message system with automatic serialization
• Broadcast or direct messaging between players
• Built-in message types: Text, DataSync, DataRequest, FileTransfer
• Custom message support via inheritance

🔧 MelonLoader Optimized

• No complex setup - just initialize and go
• Automatic resource cleanup on dispose
• Mod compatibility checking (like BetterJukebox track manifests)
• Error handling that won't crash your mod

🛠️ Requirements

• .NET Framework 4.7.2+ or .NET 6.0+
