UKismetMathLibrary::Subtract_Vector2DVector2D

function Engine Blueprint Since 4.0

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns the component-wise difference of two 2D vectors (A - B). Commonly used to compute directional offsets or deltas between screen positions.

Caveats & Gotchas

• Order matters — unlike addition, subtraction is not commutative. A - B and B - A produce opposite results.
• In Blueprint, the node is labeled 'vector2d - vector2d' with a compact '-' title. Ensure both input pins are connected to Vector2D sources, not Vector3D.

Signature

static UE_INL_API FVector2D Subtract_Vector2DVector2D(FVector2D A, FVector2D B);

Parameters

Name	Type	Description	Default
A	FVector2D	The vector to subtract from.	—
B	FVector2D	The vector to subtract.	—

Return Type

FVector2D

Example

Compute delta between two widget positions C++

FVector2D Current(300.f, 150.f);
FVector2D Previous(250.f, 120.f);
FVector2D Delta = UKismetMathLibrary::Subtract_Vector2DVector2D(Current, Previous);
// Delta = (50, 30)
