UE Input System

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

Enhanced Input is the engine's only supported input path. It lives in the EnhancedInput plugin (Engine/Plugins/EnhancedInput, enabled by default in 5.8); add "EnhancedInput" to PublicDependencyModuleNames in your Build.cs, plus "InputCore" if you touch FKey/EKeys directly and "GameplayTags" if you use input-mode filtering or the user-settings failure-reason containers. The runtime pieces are UEnhancedPlayerInput, UEnhancedInputComponent, UEnhancedInputLocalPlayerSubsystem, the data assets UInputAction / UInputMappingContext, and UEnhancedInputUserSettings for player rebinding.

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.
