Server-authoritative movement in Unity uses client-side prediction to simulate locally and reconciliation to correct state upon server validation. This maintains responsive gameplay across varying latency by applying deterministic logic and robust server-side input validation.

Unity Relay enables NAT traversal for multiplayer connectivity, while Unity Lobby handles matchmaking and lobby data. Integrating both with Netcode for GameObjects allows scalable server-authoritative gameplay across diverse network topologies.

Structuring ServerRpc and ClientRpc patterns in Unity requires defining clear bandwidth budgets and optimizing NetworkVariable usage. This minimizes data transmission while ensuring secure, server-authoritative state synchronization across clients.

Anti-cheat hardening in Unity multiplayer applies robust server-side input validation to verify client actions. By rejecting invalid inputs and maintaining authoritative state, the system resists cheating in competitive and co-op environments.

Netcode for GameObjects supports competitive multiplayer games at scale when combined with Unity Relay and Lobby. Defining deterministic logic, bandwidth budgets, and server-side validation ensures secure, responsive experiences for authoritative state management.

Desync during high latency occurs without client-side prediction and reconciliation. Implementing deterministic server-authoritative systems with Netcode for GameObjects ensures smooth gameplay by correcting client state against validated server inputs.
