UKismetMathLibrary::Add_IntInt
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Adds two integers and returns the sum. The default B=1 makes it a convenient increment node in Blueprint graphs.
Caveats & Gotchas
- • No overflow protection: INT_MAX + 1 wraps to INT_MIN silently. Use int64 or checked arithmetic when summing values that could approach 2.1 billion.
- • The default B=1 is invisible in Blueprint unless you inspect the node — a disconnected B pin silently adds 1, which can cause subtle bugs when B is intentionally 0.
