[UE5] refactor : 속성초기화 DT에서, 속성추가방법

1.속성추가방법

i) AS에 변수추가, @Getter

	UPROPERTY(BlueprintReadOnly, ReplicatedUsing = OnRep_Strength, Category = "Primary Attributes")
	FGameplayAttributeData Strength;
	ATTRIBUTE_ACCESSORS(UAuraAttributeSet, Strength);

	UPROPERTY(BlueprintReadOnly, ReplicatedUsing = OnRep_Intelligence, Category = "Primary Attributes")
	FGameplayAttributeData Intelligence;
	ATTRIBUTE_ACCESSORS(UAuraAttributeSet, Intelligence);

	UPROPERTY(BlueprintReadOnly, ReplicatedUsing = OnRep_Resilience, Category = "Primary Attributes")
	FGameplayAttributeData Resilience;
	ATTRIBUTE_ACCESSORS(UAuraAttributeSet, Resilience);

	UPROPERTY(BlueprintReadOnly, ReplicatedUsing = OnRep_Vigor, Category = "Primary Attributes")
	FGameplayAttributeData Vigor;
	ATTRIBUTE_ACCESSORS(UAuraAttributeSet, Vigor);

 

ii) 속성변경시 호출될함수 정의

UFUNCTION()
	void OnRep_Strength(const FGameplayAttributeData& OldStrength) const;

	UFUNCTION()
	void OnRep_Intelligence(const FGameplayAttributeData& OldIntelligence) const;

	UFUNCTION()
	void OnRep_Resilience(const FGameplayAttributeData& OldResilience) const;

	UFUNCTION()
	void OnRep_Vigor(const FGameplayAttributeData& OldVigor) const;

This is a helper macro that can be used in RepNotify functions to handle attributes that will be predictively modified by clients.

void UAuraAttributeSet::OnRep_MaxIdentity(const FGameplayAttributeData& OldMaxIdentity) const
{
	// 'Health' 속성의 변경을 처리
	// 핵이면, 롤백용으로 OldVal을 알아야함!
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, MaxIdentity, OldMaxIdentity);
}

void UAuraAttributeSet::OnRep_Identity(const FGameplayAttributeData& OldIdentity) const
{
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, Identity, OldIdentity);
}

void UAuraAttributeSet::OnRep_Strength(const FGameplayAttributeData& OldStrength) const
{
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, Strength, OldStrength);
}

void UAuraAttributeSet::OnRep_Intelligence(const FGameplayAttributeData& OldIntelligence) const
{
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, Intelligence, OldIntelligence);

}

void UAuraAttributeSet::OnRep_Resilience(const FGameplayAttributeData& OldResilience) const
{
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, Resilience, OldResilience);
}

void UAuraAttributeSet::OnRep_Vigor(const FGameplayAttributeData& OldVigor) const
{
	GAMEPLAYATTRIBUTE_REPNOTIFY(UAuraAttributeSet, Vigor, OldVigor);
}

iii) !!네트워크에 복제할 속성들 등록!!

// !네트워크에 복제할 속성들을 등록하는 함수! 등록안해주면 빌드에러
void UAuraAttributeSet::GetLifetimeReplicatedProps(TArray<FLifetimeProperty>& OutLifetimeProps) const
{
	...
	//4개속성추가
	DOREPLIFETIME_CONDITION_NOTIFY(UAuraAttributeSet, Strength, COND_None, REPNOTIFY_Always);
	DOREPLIFETIME_CONDITION_NOTIFY(UAuraAttributeSet, Intelligence, COND_None, REPNOTIFY_Always);
	DOREPLIFETIME_CONDITION_NOTIFY(UAuraAttributeSet, Resilience, COND_None, REPNOTIFY_Always);
	DOREPLIFETIME_CONDITION_NOTIFY(UAuraAttributeSet, Vigor, COND_None, REPNOTIFY_Always);
}

 

2.refactor : 속성초기화 DT에서

i) PS의 ASC를 BP에 노출해야함

UCLASS()
class AURA_API AAuraPlayerState : public APlayerState, public IAbilitySystemInterface
{
	GENERATED_BODY()
	
public:
	...

	UPROPERTY(VisibleAnywhere)
	TObjectPtr<UAbilitySystemComponent> AbilitySystemComponent;

BP에서 속성접근가능

ii) 여기들어갈 DT를 만들면됨

iii) 해당경로에 DT만들기

iv) DT 값넣고

DT 주입하면됨

결과
