UKismetMathLibrary::SelectInt
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Returns A if bPickA is true, otherwise returns B. A concise way to pick between two integer values based on a boolean, avoiding a full branch node in Blueprint or a ternary expression in C++.
Caveats & Gotchas
- • This is a pure node with no execution pin — both A and B are resolved before the selection is made. If either integer is produced by a function with side effects (Blueprint side, function calls with outputs), both are always called regardless of bPickA.
- • In C++, using a ternary (bPickA ? A : B) compiles identically and may be more readable. SelectInt is most useful in Blueprint where pure nodes keep the graph compact.
