To set up multiplayer match flow in Unreal Engine, use GameMode for authoritative spawning and GameState for replicated match data. PlayerController handles client-side input, while PlayerState preserves per-player data across server and clients during seamless travel.

GameMode and GameState responsibilities in Unreal Engine define authoritative match flow and spawning logic. GameMode manages rules and player spawning on the server, while GameState replicates read-only match data to all connected clients throughout the game lifecycle.

PlayerController manages input and camera setup for Unreal Engine characters by routing client inputs to the server and linking the viewport to a Pawn. ACharacter and CharacterMovementComponent then process movement with networking and prediction configurations.

You can preserve PlayerState and GameInstance data during seamless travel in Unreal Engine by leveraging their persistent lifecycle hooks. GameInstance survives level transitions entirely, while PlayerState automatically transfers across maps when using seamless travel semantics.

The best way to map authority and replication patterns across Unreal Engine gameplay classes is using a class map authority matrix. This framework documents server versus client responsibilities for GameMode, GameState, PlayerController, and Pawn to ensure scalable architectures.

Use GameInstance instead of GameState in Unreal Engine when storing data that must persist across entire sessions and level transitions. GameState is designed for replicated match-specific data, while GameInstance handles cross-session metadata unaffected by seamless travel.
