UKismetMathLibrary::MaxOfIntArray
#include "Kismet/KismetMathLibrary.h"
Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Finds the maximum integer in an array and its index. Returns MaxValue=0 and IndexOfMaxValue=-1 on an empty array.
Caveats & Gotchas
- • An empty array returns MaxValue of 0 (not INT_MIN) and an index of -1 — always check the index before treating MaxValue as meaningful.
- • If multiple elements share the maximum value, IndexOfMaxValue points to the first occurrence only.
