UKismetMathLibrary::Xor_IntInt
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Bitwise XOR of two integers (A ^ B). Commonly used to toggle specific flag bits without affecting others.
Caveats & Gotchas
- • XOR-ing a value with itself always yields 0 — this is a valid idiom to clear a register in assembly but rarely the intent in gameplay code; make sure B is a mask constant, not the same variable as A.
- • Blueprint's compact node title is '^', which is the C++ XOR operator — not the power operator as in some other languages. New users sometimes confuse this with exponentiation.
