129 — Input Mapping Profile (DA_InputMappingProfile)

Purpose

Primary Data Asset that defines all Enhanced Input bindings across three platforms (PC/Mouse, Xbox, PS5 DualSense). Single source of truth for: which Input Actions map to which keys per platform, which Input Mapping Contexts each action belongs to, context priority defaults, and all modifier configurations (Negate, Swizzle, Dead Zone, Chord). Loaded by SS_EnhancedInputManager at initialization.

Dependencies

  • Requires: None (self-contained Data Asset)
  • Required By: SS_EnhancedInputManager (loads and caches this), SS_SettingsSystem (references for key rebinding)
  • Engine/Plugin Requirements: Enhanced Input Plugin, UInputMappingContext, UInputAction

1. Enums

No enums are defined by this Data Asset. Uses E_InputContext and E_InputPlatform from SS_EnhancedInputManager.

2. Structs

3. Variables

Configuration (Instance Editable)

Variable Type Default Category Description
PlatformProfiles TArray<S_PlatformProfile> Empty Profiles One profile per platform (3 total)
ContextDefinitions TArray<S_ContextDefinition> Empty Contexts IMC asset references and defaults

4. Functions

This Data Asset has no Blueprint functions. All data retrieval is performed by SS_EnhancedInputManager reading the struct arrays directly.

5. Event Dispatchers

None. Data Assets do not have event dispatchers.

6. Overridden Events / Custom Events

None.

8. Modifier Configuration Reference

W/A/S/D Key Swizzle Setup

For IA_Move on PC:

  • W = Input Action Value.Y = 1.0 (default, no modifier)
  • S = Add Negate modifier → Input Action Value.Y = -1.0
  • D = Add Swizzle Input Axis Values modifier (Order: YXZ) + default → Input Action Value.X = 1.0
  • A = Add Swizzle Input Axis Values modifier (Order: YXZ) + Negate → Input Action Value.X = -1.0

Hold Trigger Configuration

Action Hold Duration Trigger Type
IA_Interact (physics drag) 0.3s Hold + Release
IA_Sprint 0.0s (instant) Hold (continuous while pressed)
IA_Crouch (if toggle off) 0.0s Hold
IA_Hide_HoldBreath 0.0s Hold (continuous)
IA_SkipCutscene 2.0s Hold (trigger on completion)

Chord Actions

Action Chord Combination Description
IA_ToggleAccessibility (Xbox) View + Menu (simultaneous) Two-button chord for rare action
IA_Hide_HoldBreath (Xbox/PS5) LT + RT / L2 + R2 Both triggers held simultaneously

9. Validation / Testing Checklist

  • All 30+ Input Actions are referenced in at least one platform binding
  • Every E_InputContext has a corresponding S_ContextDefinition with MappingContext assigned
  • W/A/S/D modifiers (Negate, Swizzle) produce correct axis values
  • Analog stick dead zones prevent drift on all three platforms
  • Hold actions correctly distinguish tap vs hold (Interact: tap=pickup, hold=drag)
  • IA_Vault_Climb and IA_Jump coexist correctly (contextual vs general)
  • Quick slots 1–8 are keyboard-only; console uses scroll
  • IA_UI_Back vs IA_Cancel_Drop have separate bindings (back ≠ cancel)
  • Chord actions (HoldBreath on controller, Accessibility toggle) work as two-button combos
  • Controller glyph set switches correctly on platform hot-swap
  • Edge case: No duplicate keys within the same IMC for mutually exclusive actions
  • Edge case: Dead zone on Scroll Wheel (IA_QuickSlotScroll) prevents accidental scrolling

10. Reuse Notes

  • This Data Asset is the single source of truth for ALL input bindings. No other system hardcodes key references.
  • When adding a new Input Action: 1) Create the IA_ asset, 2) Add it to this DA under the correct context/platform, 3) The IMC asset references this DA — update the IMC accordingly.
  • Platform profiles can be authored in the Content Browser; designers don't need to touch Blueprint graphs.
  • For accessibility: AxisInvertSettings allows per-player Y-axis inversion without modifying the core bindings.
  • bBlockLowerContexts on S_ContextDefinition controls whether IMC_Hiding passes through IA_Move to IMC_Default (it blocks) vs whether IMC_UI allows IA_QuickSlotScroll passthrough (it doesn't).
  • Console-specific glyphs (Xbox ABXY vs PS5 Cross/Circle/Square/Triangle) are handled by ControllerGlyphSet for dynamic UI updates.
