GONet - Unity GameObject Networking

Production-ready multiplayer networking for Unity with auto-magical GameObject state synchronization.

GONet is a high-performance networking library for Unity that makes multiplayer game development simple and powerful. If you need to network something and a GameObject is involved, GONet is the answer.

Key Features

• Auto-Magical Data Sync - Add [GONetAutoMagicalSync] to any field and it syncs automatically
• Zero-Latency Client Spawning - GONetId batch system eliminates spawn delay
• Enhanced RPC System - Async/await support, server validation, persistent delivery
• Scene Management - Server-authoritative with late-joiner synchronization
• Unity Addressables - Full support for scenes and runtime prefab spawning
• Adaptive Congestion - Auto-scaling packet pools handle burst traffic
• Velocity-Augmented Sync - 90%+ bandwidth reduction for slow-moving objects
• Auto-Detection - Zero config local testing (first instance = server)

Quick Start

// 1. Add GONetParticipant to GameObjects
// 2. Mark fields to sync
[GONetAutoMagicalSync] public float health;
[GONetAutoMagicalSync] public Vector3 velocity;

// 3. Use RPCs
[ServerRpc]
async Task<ChatResult> SendChatMessage(string message) { }

[ClientRpc]
void NotifyAllClients(string message) { }

// 4. Network spawning works automatically
GameObject.Instantiate(prefab, position, rotation);

Installation

1. Import GONet package from Unity Asset Store
2. Add GONet_GlobalContext prefab to your first scene
3. Add GONetParticipant component to GameObjects you want to network
4. Build executable
5. Hit Play (first instance becomes server, rest become clients)
