UBlueprintSetLibrary::Set_GetLastIndex
#include "Kismet/BlueprintSetLibrary.h"
Access: public
Specifiers: staticBlueprintPureCustomThunk
Description
Returns the highest valid index into the set — Set_Length minus one — for use with Set_GetItemByIndex.
Caveats & Gotchas
- • Returns -1 for an empty set rather than 0; check for this before using the result to drive a loop bound.
- • Exists mainly to pair with Set_GetItemByIndex for manual iteration; a ForEachLoop node is simpler for most Blueprint use cases.

int32 Example
Bounds-check before indexing C++
TSet<int32> Values = {10, 20, 30};
const int32 LastIndex = Values.Num() - 1; // native equivalent of Set_GetLastIndex
if (LastIndex >= 0)
{
// safe to index
