Input Components

Overview

Input is split between management of input context objects (cursor, mapping contexts) and binding of Enhanced Input to quick slots, toggleable widgets, and key-hold actions. UMIPPlayerInputManagerComponent holds a map of tag → input context object and provides cursor/input mode helpers. UMIPEnhancedInputComponent binds from a config asset to quick slot, widget toggle, and key-hold callbacks.

Key traits:

  • UMIPPlayerInputManagerComponent – Client-only; owns InputContextObjectClasses (tag → class) and runtime InputContextObjects; init/clear/reinit; show/hide cursor and set UI-only vs game+UI input mode.
  • UMIPEnhancedInputComponent – UEnhancedInputComponent; BindInputConfig(InputConfig); routes quick slot, toggleable widget, and key-hold events to the appropriate components (QuickBar, ClientWidgetsManager, etc.).

UMIPPlayerInputManagerComponent

  • Base: UMIPClientPlayerControllerComponent.
  • Attachment: PlayerController (client).
  • API: InitInputContextObjects(), ClearAllMappings(), ReinitializeContextObjects(), ShowCursorAndSetUIOnlyMode(), HideCursorAndSetGameAndUIMode().
  • Properties: InputContextObjects (runtime map: FGameplayTag → UMIPBasePlayerPawnInputContextObject), InputContextObjectClasses (tag → TSubclassOf). Context objects are not ActorComponents; they are UObject-based.

UMIPEnhancedInputComponent

  • Base: UEnhancedInputComponent (Enhanced Input).
  • Attachment: PlayerController (replaces or augments default input component).
  • API: BindInputConfig(InputConfig) – binds from UMIPInputConfigAsset to quick slot (pressed/released/held), toggleable widget (pressed/released/held), key-hold (pressed/released/held). Caches refs to ASC, QuickBarComponent, ClientWidgetsManagerComponent, PlayerDynamicTagsContainer for callbacks.
  • Callbacks (protected): QuickSlotInputPressed/Released/Held(InQuickSlotIndex), ToggleableWidgetInputPressed/Released/Held(InTag), KeyHoldInputPressed/Released/Held(InTag).

Integration

  • UMIPCursorComponent and UI input mode are often driven by the same input context or by UMIPPlayerInputManagerComponent (ShowCursor/HideCursor).
  • UMIPQuickBarComponent receives quick slot input from UMIPEnhancedInputComponent.
  • UMIPClientWidgetsManagerComponent receives toggleable widget input for opening/closing panels.
