SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Multiplayer Unity projects often struggle with inconsistent state, high bandwidth use, poor latency handling, and fragile matchmaking; this Skill provides a repeatable architecture and best-practice patterns to build robust, server-authoritative networked games that remain smooth under real-world latency.

Core Features & Use Cases

  • Network architecture: Netcode for GameObjects setup, NetworkVariable-driven replication, NetworkObject spawning, and authority models that ensure server validation for gameplay-critical state.
  • Latency & bandwidth management: Client prediction, server reconciliation, lag compensation (server rewind), delta compression, quantized transforms, and a 20KB/s per-player bandwidth target with 20-30Hz sync.
  • Integration & testing: Unity Relay and Lobby integration for matchmaking, spawn/connect flows, automated multiplayer tests and Unity-MCP tooling for scene/setup automation and log-based verification.
  • Use case: Build a 60fps competitive multiplayer arena with authoritative combat, client-side movement prediction, hit registration rewind, and reliable reconnect/host migration handling.

Quick Start

Use the unity-multiplayer skill to scaffold a NetworkManager with Netcode, enable Unity Relay and Lobby, create networked player prefabs with NetworkObject and NetworkTransform, and run Unity-MCP playmode tests to validate state synchronization.

FAQPage Schema
How do I implement client prediction and server reconciliation in Unity multiplayer?

To implement client prediction and server reconciliation in Unity multiplayer, use Netcode for GameObjects with server-authoritative state replication. The skill provides patterns to predict local movement, validate inputs on the server, and reconcile differences using delta compression and quantized transforms to maintain smooth gameplay under latency.

What's the best way to handle matchmaking in Unity using Relay and Lobby?

The best way to handle matchmaking in Unity using Relay and Lobby is to integrate Unity Relay for network routing and Unity Lobby for match creation. This skill scaffolds the spawn and connect flows, allowing players to join authoritative servers without exposing direct host IPs.

How does lag compensation work in a Unity server-authoritative game?

Lag compensation in a Unity server-authoritative game works by rewinding the server state to match the shooter's perceived latency during hit registration. This skill implements server rewind techniques alongside NetworkVariable replication to ensure fair and accurate combat validation in multiplayer arenas.

Can I achieve 20KB/s bandwidth per player with 30Hz state sync in Netcode for GameObjects?

Yes, you can achieve 20KB/s bandwidth per player with 30Hz state sync in Netcode for GameObjects by applying delta compression and quantized transforms. This skill optimizes NetworkVariable replication and interpolation to meet strict bandwidth targets for real-time gameplay.

How do I validate state synchronization in Unity multiplayer tests?

To validate state synchronization in Unity multiplayer tests, use automated playmode tests and Unity-MCP tooling for scene automation. The skill supports log-based verification to ensure NetworkObject spawning and NetworkVariable replication function correctly across server and client instances.

Do I need an authoritative server for competitive Unity multiplayer combat?

You need an authoritative server for competitive Unity multiplayer combat to prevent cheating and maintain consistent state. This skill establishes a server-authoritative architecture with client prediction and lag compensation to ensure fair hit registration and reliable gameplay.
