UKismetInputLibrary::PointerEvent_GetCursorDelta

function Engine Blueprint Since unknown

#include "Kismet/KismetInputLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns how far the mouse cursor moved since the last pointer event was handled — the standard source for camera look and drag deltas.

Caveats & Gotchas

• Delta is in screen pixels, not normalized — scale it by a sensitivity value before feeding it into camera rotation.
• Not populated for touch-only gesture events; use PointerEvent_GetGestureDelta for pinch/rotate gestures instead.
