UKismetMathLibrary::SelectVector
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns A if bPickA is true, otherwise returns B. Provides a branch-free conditional selection of a vector value usable inside Blueprint pure graphs.
Caveats & Gotchas
- • In C++, a plain ternary `bPickA ? A : B` is clearer and cheaper; this function exists primarily for Blueprint's visual scripting where branch nodes add visual noise.
- • Both A and B are always evaluated before the call — there is no short-circuit behaviour, so avoid passing expensive computed vectors as arguments when only one path is needed.
