C++ - Configuring the Struct Operator "<<"

//Example Code;

USTRUCT(BlueprintType)

struct FMapInformation

{

GENERATED_USTRUCT_BODY()

public:

TEnumAsByte<ETileType::Type> TileType;

FVector TileLocation;

friend FArchive& operator << (FArchive& Ar, FMapInformation& OtherInfo)

{

Ar << OtherInfo.TileType << OtherInfo.TileLocation;

return Ar;

}

};

Must be specified as reference unconditionally!!

• friend FArchive& operator << (FArchive& Ar, FMapInformation& OtherInfo)

Otherwise there will be problems.
