UE Gameplay Framework

Target engine: UE 5.8. APIs below are verified against the 5.8 headers; older forms are listed under "Deprecated — do not use".

The gameplay framework is the set of classes the engine spawns for you — AGameModeBase, AGameStateBase, APlayerController, APlayerState, APawn, ACharacter, AHUD, UGameInstance — plus the join, spawn, match-state, travel and damage flows that wire them together. All of it ships in the Engine module (Classes/GameFramework, Classes/Engine, Classes/Kismet), so Build.cs needs "Core", "CoreUObject", "Engine". Add "EnhancedInput" when binding input, and "OnlineSubsystem" + "OnlineSubsystemUtils" (or "OnlineServicesInterface") only when touching sessions.

Context

Read .agents/ue-project-context.md if it exists (module names, conventions, enabled plugins, GAS/networking setup). Do not stop if it is missing.

Identify the area from the request and the codebase. Ask only when two plausible readings would produce different code.
