UKismetMathLibrary::Less_IntInt
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns true if integer A is strictly less than integer B (A < B).
Caveats & Gotchas
- • Comparing values that resulted from signed integer overflow is undefined behaviour in C++ — sanitise or clamp before comparing when overflow is possible.
- • For Blueprint-only projects, prefer the built-in `<` node; this function is the C++ call name that the node maps to and is rarely called explicitly in game code.
