UKismetInputLibrary::ModifierKeysState_IsAltDown

function Engine Blueprint Since unknown

#include "Kismet/KismetInputLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns true if either the left or right Alt key was held down when the modifier-key state snapshot was captured.

Caveats & Gotchas

• Operates on a captured FSlateModifierKeysState snapshot, not a live poll — call GetModifierKeysState first to obtain a current snapshot.
• Does not distinguish between left and right Alt; test the underlying FInputEvent with InputEvent_IsLeftAltDown or InputEvent_IsRightAltDown if you need that distinction.
