UBlueprintSetLibrary::Set_AddItems
#include "Kismet/BlueprintSetLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Adds every element of an array to a set in one call, skipping any that are already present.
Caveats & Gotchas
- • Equivalent to calling Set_Add in a loop over NewItems, but avoids per-iteration Blueprint node overhead.
- • Duplicate items within NewItems itself collapse to a single set entry, same as any other set insertion.
