GetGameState — get the current GameState

Pure node. Cast to your AGameState subclass to access custom replicated data.

GameState

Replicated state shared across all clients (e.g. match time, team scores). Read-only from clients.

GameMode

Defines the rules + default classes (Pawn, PlayerController, GameState) for a level. Only exists on the server.

GetGameState — get current game state

GetPlayerState — get the PlayerState for a player

Pure node. Call on PlayerController or Pawn. Cast to your BP_PlayerState subclass.

GetGameMode — get current game mode

UGameplayStatics::GetGameMode. Cast to your custom GameMode class.

PlayerState

Replicated per-player state (name, score). Lives on the server and replicates to all clients.

GetGameMode — get the current GameMode

Pure node. Cast result to your GameMode subclass to access custom properties.

Game subsystem: persistent game manager with auto-init

SETUP: Create Blueprint inheriting UGameInstanceSubsystem (or UWorldSubsystem for level-scoped). Override Initialize(Collection) to set up. Override Deinitialize to clean up. Add game variables here (Score, PlayTime, Settings). ACCESS FROM ANYWHERE: GetGameInstance → GetSubsystem(BP_GameSubsystem) → CastTo<BP_GameSubsystem> → access variables. WHY: Subsystems auto-create, auto-destroy, and don't need FindActor. Better than GameInstance for well-organized systems. UGameInstanceSubsystem persists across levels. UWorldSubsystem is recreated each level.

GetGameInstance — get the GameInstance (persists across levels)

Pure node. Ideal for storing data that persists across level loads.
