UKismetMathLibrary::Multiply_Vector2DFloat

Description
Scales a 2D vector uniformly by a scalar, returning (A.X*B, A.Y*B). The most common way to scale a direction or speed vector in 2D.
Caveats & Gotchas
- • The scalar B is applied to both X and Y equally. For per-axis scaling, use Multiply_Vector2DVector2D.
- • The parameter is declared as double in the header (UE5 double precision), but Blueprint exposes it as a float pin.

| B | double | The scalar to multiply both components by. | — |
Return Type
FVector2D Example
Scale a movement direction vector C++
FVector2D Direction(1.f, 0.f);
float Speed = 500.f;
FVector2D Velocity = UKismetMathLibrary::Multiply_Vector2DFloat(Direction, Speed);
// Velocity = (500, 0)Tags
