  • 부모 클래스 UAttributeSet에 있는 매크로 함수들
  • ATTRIBUTE_ACCESSORS(어트리뷰트셋, 어트리뷰트)
    • Get, Set, Init 함수들을 만들어 줌
    • #include "AbilitySystemComponent.h" 추가
    • 사용 예) Get + 어트리뷰트 이름, GetHealth, SetHealth, InitHealth
• UPPCharacterAttributeSet();
  • 생성자
• ATTRIBUTE_ACCESSORS(UPPCharacterAttributeSet, AttackRange);
  • 각 어트리뷰트 마다 매크로를 통하여 Get, Set Init함수를 생성
• UPROPERTY(BlueprintReadOnly, Category = "Attack", Meta = (AllowPrivateAccess = true))
  FGameplayAttributeData AttackRange;
  • 어트리뷰트 생성
• virtual bool PreGameplayEffectExecute(struct FGameplayEffectModCallbackData& Data) override;
  • GameplayEffect로 어트리뷰트 수정 전 실행되는 함수
  • 활용 예) 캐릭터가 무적상태일 경우 return false를 해 어트리뷰트 수정을 못하게 할 수 있음
• virtual void PostGameplayEffectExecute(const struct FGameplayEffectModCallbackData& Data) override;
  • GameplayEffect로 어트리뷰트 수정 후 실행되는 함수
• virtual void PreAttributeChange(const FGameplayAttribute& Attribute, float& NewValue) override;
  • 어트리뷰트를 직접적으로 수정할때 실행되는 함수
