UKismetMathLibrary::Or_Int64Int64
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Performs a bitwise OR on A and B and returns the result. Commonly used to combine or set bits in a 64-bit flags field.
Caveats & Gotchas
- • OR can only set bits, never clear them. To clear a bit, AND with the bitwise NOT of the mask: And_Int64Int64(Flags, Not_Int64(BitMask)).
- • Blueprint marks this as CommutativeAssociativeBinaryOperator, so it can be chained with multiple inputs in a single node. Order of evaluation is deterministic but the graph may look misleading if the inputs are not all pure.
