What is the recommended way of referencing Blueprint objects from c++?

A simple example of spawning a new object instance from a blueprint (or any other type of) Uclass:



UObject* AMySpawner::NewObjectInstance(UObject* Context, UClass* Class) {

    if ( !Context || !Context->IsValidLowLevelFast() || Context->IsPendingKill() ) { return nullptr; }
    if ( Class == nullptr ) { return nullptr; }

    auto World = GEngine->GetWorldFromContextObject ( Context, EGetWorldErrorMode::LogAndReturnNull );
    if ( World != nullptr ) { return NewObject<UObject>( Context , Class ); }

    return nullptr;
}

Or just getting the CDO (class default object) which is always spawned by the engine when game exe is launched:



UObject* AMySpawner::GetClassDefaultObject(UClass* Class) {
    return Class->GetDefaultObject(true);
}
