UKismetMathLibrary::Subtract_VectorFloat
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Subtracts a scalar float from every component of a vector, returning {A.X-B, A.Y-B, A.Z-B}. Useful for uniformly shrinking extents or applying a uniform negative bias.
Caveats & Gotchas
- • Subtracting a positive scalar decreases all three axes equally, which changes the vector's magnitude and direction unless A is along a single axis — verify this is the intended behavior before using it for direction calculations.
- • There is no divide-by-zero risk here, but the result may have negative components, which can silently invert behavior if the result is later used as an extent or scale.
