UBlueprintSetLibrary::Set_Difference
#include "Kismet/BlueprintSetLibrary.h"
Access: public
Specifiers: staticBlueprintCallableCustomThunk
Description
Assigns Result to the relative difference of Set A and Set B — every element in A that is not also found in B.
Caveats & Gotchas
- • Difference is not commutative: A minus B is not the same as B minus A. Put the set whose elements you want to keep in the A slot.
- • Also called the relative complement of B in A.
