UKismetMathLibrary::BooleanNOR
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns true only when both A and B are false (logical NOT OR). Useful for conditions that should only proceed when all flags are inactive.
Caveats & Gotchas
- • NOR is equivalent to NOT (A OR B) — it is true only in the single case where both inputs are false. Do not confuse with NAND, which is false only when both inputs are true.
- • Like other Blueprint boolean operators, NOR does not short-circuit — both inputs are evaluated before the result is produced.
