UKismetInputLibrary::PointerEvent_GetPointerIndex

function Engine Blueprint Since unknown

#include "Kismet/KismetInputLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Returns the unique identifier of the pointer that raised this event — for touch input this is typically the finger index.

Caveats & Gotchas

• For standard single-cursor mouse input this is usually 0 and not useful; it matters mainly when handling multi-touch gestures.
• Pointer indices are only guaranteed unique among pointers that are simultaneously active, not across the lifetime of the app.
