EnhancedInput

Defines a mapping between a key activation and the resulting enhanced action An key could be a button press, joystick axis movement, etc.

A binding to an input action trigger event.

Binding wrapper structs.

Binds an action value for later reference.

Run time queryable action instance Generated from UInputAction templates above

A basic binding unique identifier

Binds a delegate to an event on a key chord.

Delegate signature for debug key events.

Potential issue raised with a mapping request.

The public interface to this module

Includes native functionality shared between all subsystems.

Unified storage for both native and dynamic delegates with any signature

Implement an Actor component for input bindings.

Global input handling subsystem TODO: For now this is a non-functional placeholder.

Per local player input subsystem.

Internal representation containing event variants.

Input action definition. These are instanced per player (via FInputActionInstance)

UInputMappingContext : A collection of key to action mappings for a specific input context Could be used to: Store predefined controller mappings (allow switching between controller config variants).

Base class for building modifiers.

Modifier collection A user definable group of modifiers that can be easily applied to multiple actions or mappings to save duplication work.

Dead Zone Input values within the range LowerThreshold -> UpperThreshold will be remapped from 0 -> 1.

FOV Scaling Apply FOV dependent scaling to input values, per axis

Negate Inverts input per axis

Response Curve Exponential Apply a simple exponential response curve to input values, per axis

Response Curve User Defined Apply a custom response curve to input values, per axis

Scalar Scales input by a set factor per axis

Smooth Smooth inputs out over multiple frames

Swizzle axis components of an input value. Useful to map a 1D input onto the Y axis of a 2D action.

Input space to World space conversion Auto-converts axes within the Input Action Value into world space allowing the result to be directly plugged into functions that take world space values.

Base class for building triggers.

UInputTriggerChordAction Applies a chord action that must be triggering for this trigger's action to trigger

UInputTriggerChordBlocker Automatically instantiated to block mappings that are masked by a UInputTriggerChordAction chord from firing whilst the chording key is active.

UInputTriggerDown Trigger fires when the input exceeds the actuation threshold.

UInputTriggerHold Trigger fires once input has remained actuated for HoldTimeThreshold seconds.

UInputTriggerHoldAndRelease Trigger fires when input is released after having been actuated for at least HoldTimeThreshold seconds.

UInputTriggerPressed Trigger fires once only when input exceeds the actuation threshold.

UInputTriggerPulse Trigger that fires at an Interval, in seconds, while input is actuated.

UInputTriggerReleased Trigger returns Ongoing whilst input exceeds the actuation threshold.

UInputTriggerTap Input must be actuated then released within TapReleaseTimeThreshold seconds to trigger.

Base class for building triggers that have firing conditions governed by elapsed time.

Delegate signature for action events.

Used to force clone constructor calls only.

Mapping issues arising from a QueryMapKeyIn... call.

Result summary from a QueryMapKeyIn... call.

Trigger events are the Action's interpretation of all Trigger State transitions that occurred for the action in the last tick

Trigger states are a light weight interpretation of the provided input values used in trigger UpdateState responses.

Trigger type determine how the trigger contributes to an action's overall trigger event the behavior of the trigger
