Interactable UI Config

UMounteaInteractableUIConfig (UDataAsset) controls the interaction widget class, its data source, and per-key input-prompt textures.

Fields

Field	Type	Default	Purpose
DefaultInteractionWidgetClass	TSoftClassPtr<UUserWidget>	none	Widget shown in interaction range when this component is the selected action. Must implement IActorInteractionWidget
DefaultInteractableDataTable	TSoftObjectPtr<UDataTable>	none	Supplies display data to interactable widgets (row type is project-defined)
MappingKeys	TMap<FKey, FKeyOnDevice>	empty	Per-key texture mapping for input prompt display
WidgetUpdateFrequency	float (s)	0.05	How often the interaction widget polls for data updates

Key-to-Texture Mapping

MappingKeys maps an FKey (e.g. EKeys::E, EKeys::Gamepad_FaceButton_Bottom) to an FKeyOnDevice, which is itself a list of FKeyOnDevicePair entries:

USTRUCT(BlueprintType)
struct FKeyOnDevicePair
{
    TSoftObjectPtr<UTexture2D> KeyTexture;
    ECommonInputType SupportedDeviceType;   // Keyboard, Gamepad, Touch, ...
    TArray<FString> SupportedPlatforms;     // empty = all platforms
    TArray<FString> BlacklistedDeviceIDs;
};

This lets one logical key resolve to different prompt textures depending on the connected input device and platform - a single FKey can carry a keyboard glyph, a Gamepad glyph, and platform-specific variants (e.g. a different face-button icon per console) without your project writing device-detection logic in every widget.

This is data, not binding

MappingKeys only supplies textures for display. It doesn't bind any input itself - your project still owns the actual Enhanced Input Action bindings; this table exists purely so an interaction widget can show "press [E-glyph]" without hardcoding a texture per key.

Resolving From Code

const UMounteaInteractionSystemSettings* settings = GetDefault<UMounteaInteractionSystemSettings>();
const UMounteaInteractableUIConfig* config = settings ? settings->GetInteractableUIConfig() : nullptr;

Or via the ported legacy helpers on UMounteaInteractableStatics: GetDefaultWidgetUpdateFrequency(), GetInteractableDefaultDataTable(), GetInteractableDefaultWidgetClass().

See User Interface for the widget interface these classes must implement.
