IA_* — Input Actions + IMC_* — Input Mapping Contexts

UE5 Path: Content/Framework/Input/Actions/ + Content/Framework/Input/Contexts/ Plugin Required: Enhanced Input (enabled in project plugins)

Prerequisites

  1. Project Settings → Plugins → Enhanced Input → Enabled ✓
  2. Restart editor after enabling

Input Actions — Create All (17 assets)

Gameplay Actions

Asset Name Value Type Description
IA_Move Axis2D WASD / Left Stick movement
IA_Look Axis2D Mouse / Right Stick camera
IA_Jump Digital (bool) Jump / Vault
IA_Sprint Digital (bool) Sprint (hold)
IA_Crouch Digital (bool) Toggle crouch
IA_Interact Digital (bool) Primary interact (E / X)
IA_InteractHold Digital (bool) Hold interaction (hold E)
IA_Reload Digital (bool) Reload weapon
IA_Fire Digital (bool) Primary fire
IA_AimDownSights Digital (bool) Aim (hold)
IA_Melee Digital (bool) Melee attack
IA_UseItem Digital (bool) Use equipped/quick-slot item
IA_ToggleInventory Digital (bool) Open/close inventory
IA_ToggleJournal Digital (bool) Open/close journal
IA_Pause Digital (bool) Pause menu
IA_Hide Digital (bool) Enter/exit hiding
IA_Peek Digital (bool) Peek while hiding

How to Create Each

  1. Content Browser → Content/Framework/Input/Actions/
  2. Right-click → Input → Input Action
  3. Name: IA_{Action}
  4. Open the asset → set Value Type per the table above
  5. Optionally add Triggers (Tap, Hold, Pressed, Released)
  6. Optionally add Modifiers (Negate, Dead Zone, Swizzle Axis)

Common Trigger/Modifier Setup

IA_Interact:    Trigger: Pressed
IA_InteractHold:  Trigger: Hold (HoldTimeThreshold = 0.5)
IA_Sprint:      Trigger: Hold
IA_Crouch:      Trigger: Pressed (toggle behavior in code)
IA_Fire:        Trigger: Pressed + Trigger: Hold (for auto-fire)
IA_AimDownSights: Trigger: Hold
IA_Pause:       Trigger: Pressed

Input Mapping Contexts — Create All (6 assets)

Asset Name Priority Contains These Actions When Active
IMC_Default 0 Move, Look, Jump, Sprint, Crouch, Interact, InteractHold, Reload, Fire, AimDownSights, Melee, UseItem, ToggleInventory, ToggleJournal, Pause Always (lowest priority)
IMC_Hiding 5 Hide, Peek (overrides some IMC_Default) While hidden
IMC_WristwatchUI 10 Interact (re-mapped to wristwatch), Look Wristwatch mode
IMC_Inspection 20 Look (rotation only), Interact (exit inspect) 3D inspect mode
IMC_UI 100 Pause (close), Interact (confirm) Any menu open
IMC_Vehicle 3 Move (vehicle), Look, Interact (exit) While in vehicle

How to Create Each

  1. Content Browser → Content/Framework/Input/Contexts/
  2. Right-click → Input → Input Mapping Context
  3. Name: IMC_{Context}
  4. Open → Add Mapping for each action in the table
  5. For each mapping, select the IA_ asset and assign a key binding

Default Key Bindings (PC — IMC_Default)

Action Primary Key Secondary Key
IA_Move W/A/S/D Left Stick
IA_Look Mouse XY Right Stick
IA_Jump Space A (gamepad)
IA_Sprint Left Shift Left Stick Click
IA_Crouch Left Ctrl B (gamepad)
IA_Interact E X (gamepad)
IA_Reload R Y (gamepad)
IA_Fire Left Mouse Right Trigger
IA_AimDownSights Right Mouse Left Trigger
IA_Melee V Right Stick Click
IA_UseItem Q D-Pad Up
IA_ToggleInventory Tab Select
IA_ToggleJournal J D-Pad Left
IA_Pause Escape Start

Context Priority System

IMC_UI (100)           ← Highest — blocks everything
IMC_Inspection (20)
IMC_WristwatchUI (10)
IMC_Hiding (5)
IMC_Vehicle (3)
IMC_Default (0)        ← Lowest — always active

When a higher-priority context is pushed, conflicting inputs from lower contexts are overridden. Non-conflicting inputs still pass through.

Test It

  • All 17 IA_ assets created with correct Value Types
  • All 6 IMC_ assets created with correct mappings
  • PIE: WASD moves character, mouse looks around, E interacts
  • Push IMC_Hiding → IMC_Default actions blocked except those also in IMC_Hiding
  • Open inventory → IMC_UI pushes → cursor appears → game inputs blocked
