UKismetArrayLibrary::Array_LastIndex
#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintPureCustomThunk
Description
Returns the index of the last element in an array.
Caveats & Gotchas
- • Returns -1 for an empty array rather than 0, so don't assume the result is always a valid index — pair with Array_IsEmpty or Array_IsValidIndex first.
- • Equivalent to Array_Length(TargetArray) - 1, provided purely for readability in Blueprint graphs.
- • Marked BlueprintThreadSafe.
