Different ways to instantiate the object

Development Programming & Scripting

I found about four different ways to instantiate the object, but not sure if my understanding are clear.

  • NewObject<T>() function used when we want to make at the instance of UObject. For example, it can be any ActorComponents.

    USomeComponent sc = NewObject<USomeComponent> (class);

  • ConstructObject<T>() one more way to init UObject…

  • CreateDefaultSubobject<T>() but using this one function we also can create an instance of any class inherited from UObject.

So first question: What is the difference if we can use these functions for one purpose? How and when and why we need to use any of them?

  • SpawnActor<T>() used for instantiating an object of AActor class.

Question two: Is it a fine way to init Actor's? What is the place in the game when we need to init exactly Actors? Write, please, any example except for GameMode.

  • ConstructorHelpers::FObjectFinder<T>() pretty clear scope of using. To load and set up assets. Can this method be useful in some other place?
