I think I figured out how to pass both variables into one value.
FVector2D ACppRadarHUD::GetDotPosition(AActor* Actor)
{
float FvectorX;
float FvectorY;
FVector2D Result = FvectorX + FvectorY;
FvectorX = UKismetMathLibrary::InverseTransformLocation(UGameplayStatics::GetPlayerPawn(GetWorld(), 0)->GetActorTransform(), Actor->GetActorLocation()).X / ObjectDistanceScale;
FvectorY = UKismetMathLibrary::InverseTransformLocation(UGameplayStatics::GetPlayerPawn(GetWorld(), 0)->GetActorTransform(), Actor->GetActorLocation()).Y / ObjectDistanceScale;
return Result;
}
