FAQPage Schema

How do I set up Unity multiplayer with Netcode for GameObjects?▼

To set up Unity multiplayer, install the Netcode for GameObjects package, add a NetworkManager to your scene, and configure UnityTransport as the transport protocol. This establishes the foundational networking layer for client-host communication.

What is the best way to synchronize game state across Unity clients?▼

The best way to synchronize game state across Unity clients is using NetworkVariable for shared state and RPCs for event-based communication. This ensures server-authoritative patterns keep clients in sync.

Do I need Unity Gaming Services to implement lobby and relay functionality?▼

Unity Gaming Services are optional but recommended for lobby and relay functionality. You can implement local co-op or direct online games without them, but they simplify lobby-based multiplayer match.

How does server-authoritative networking work in Unity NGO?▼

Server-authoritative networking in Unity NGO means the server validates state changes and RPCs before clients apply them. Ownership rules dictate which client can modify specific NetworkObject instances.

Can I use this approach for both local co-op and online multiplayer games?▼

Yes, this approach supports both local co-op and online multiplayer games. The Netcode for GameObjects workflow scales from shared-screen local play to fully networked online sessions.
