AttributeSet

AttributeSet显示创建，隐式添加

ALyraCharacterWithAbilities::ALyraCharacterWithAbilities(const FObjectInitializer& ObjectInitializer)
	: Super(ObjectInitializer)
{
	AbilitySystemComponent = ObjectInitializer.CreateDefaultSubobject<ULyraAbilitySystemComponent>(this, TEXT("AbilitySystemComponent"));
	AbilitySystemComponent->SetIsReplicated(true);
	AbilitySystemComponent->SetReplicationMode(EGameplayEffectReplicationMode::Mixed);

	CreateDefaultSubobject<ULyraHealthSet>(TEXT("HealthSet"));
	CreateDefaultSubobject<ULyraCombatSet>(TEXT("CombatSet"));

	// AbilitySystemComponent needs to be updated at a high frequency.
	NetUpdateFrequency = 100.0f;
}

HealthSet和CombatSet创建后作为ALyraCharacterWithAbilities的Subobj存在

void UAbilitySystemComponent::InitializeComponent()
{
	Super::InitializeComponent();

	// Look for DSO AttributeSets (note we are currently requiring all attribute sets to be subobjects of the same owner. This doesn't *have* to be the case forever.
	AActor *Owner = GetOwner();
	InitAbilityActorInfo(Owner, Owner);	// Default init to our outer owner

	// cleanup any bad data that may have gotten into SpawnedAttributes
	for (int32 Idx = SpawnedAttributes.Num()-1; Idx >= 0; --Idx)
	{
		if (SpawnedAttributes[Idx] == nullptr)
		{
			SpawnedAttributes.RemoveAt(Idx);
		}
	}

	TArray<UObject*> ChildObjects;
	GetObjectsWithOuter(Owner, ChildObjects, false, RF_NoFlags, EInternalObjectFlags::Garbage);

	for (UObject* Obj : ChildObjects)
	{
		UAttributeSet* Set = Cast<UAttributeSet>(Obj);
		if (Set)  
		{
			SpawnedAttributes.AddUnique(Set);
			bIsNetDirty = true;
		}
	}

	SetSpawnedAttributesListDirty();
}

此处Component的outer为Actor，从Actor的Subobj拿到AttributeSets并添加到AbilityComponent
