UKismetMathLibrary::Subtract_Vector2DFloat
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Subtracts a scalar float from both components of a 2D vector, returning (A.X - B, A.Y - B). Useful for shrinking or offsetting a uniform 2D region.
Caveats & Gotchas
- • The scalar B is subtracted from both X and Y equally. To subtract different amounts per axis, use Subtract_Vector2DVector2D instead.
- • The parameter is declared as double in the header (UE5 double precision), but Blueprint treats it as a float pin.

FVector2D Example
Remove uniform border from a rect extent C++
FVector2D Extent(512.f, 256.f);
