UBlueprintSetLibrary::Set_Add
#include "Kismet/BlueprintSetLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Adds an item to a set. If an equal item is already present the set is left unchanged, since sets only ever store one copy of each unique value.
Caveats & Gotchas
- • Silently does nothing if NewItem already compares equal to an existing element — there's no output pin telling you whether an insertion actually happened.
- • In C++, call TSet::Add() directly instead of routing through this wildcard CustomThunk wrapper.
