UKismetInputLibrary::InputEvent_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 this input event occurred.

Caveats & Gotchas

• Reflects modifier state at the moment the event fired, not a live poll of current key state.
• On Windows, Alt is also used by the OS for menu access keys and Alt+Tab, so some Alt key-down events may never reach the game window.
