GameplayAbilitySystem을 이용한 RPG 프로젝트 - (34) Attribute와 연관된 Attribute

이번 포스트에서는 이전에 만든 Primary Attribute를 자세하게 알아보고

이 Primary Attribute에 영향을 받아 동작하는 새로운 Attribute들을 알아보겠습니다.

 

1) Primary Attribute

• 1) Strength : 물리적 데미지를 증가시키는 스탯
• 2) Intelligence : 마법 데미지를 증가시키는 스탯
• 3) Resilience : 방어구와 방어구 효율을 증가시키는 스탯
• 4) Vigor : 체력을 증가시키는 스탯

크게 위의 4가지로 구성되어 있습니다.

오늘 만들어볼 Secondary Attribute의 경우 Primary Attribute에 영향을 받으면서

추가적으로 Secondary Attribute끼리도 영향을 받게끔 설계하도록 하겠습니다.

 

2) Secondary Attribute

• 1) Armor - Resilience와 연관 : 받는 데미지를 감소시키소, 방어 기회를 증가
• 2) Armor Penetration - Resilience와 연관 : 적의 방어구를 무시할 확률 증가, 크리티컬 공격 찬스 증가
• 3) Block Chance - Armor와 연관 : 확률적으로 받는 데미지를 반감
• 4) Critial Hit Chance - Armor Penetration와 연관 : 2배의 데미지를 줄 확률
• 5) Critical Hit Damage - Armor Penetration와 연관 : 크리티컬 공격 시 추가로 줄 데미지
• 6) Critical Hit Resistance - Armor와 연관 : 적의 크리티컬 확률을 줄임
• 7) Health Regeneration - Vigor와 연관 : 초당 체력 회복률을 상승
• 8) Mana Regeneration - Intelligence와 연관 : 초당 마나 회복률을 상승
• 9) Max Health - Vigor와 연관 : 최대 체력량
• 10) Max Mana - Intelligence와 연관: 마나 최대량

위와 같이 구성되어 있습니다.

이제 기존에 사용하던 AttributeSet에 Secondary Attribute를 추가하겠습니다.

 

3) AuraAttributeSet

추가한 SecondAttribute들에 대해 레플리케이션하는 함수들을 새로 만들었고

Actor의 생명주기동안 레플리케이션되고 있는 프로퍼티들을 리턴하는

GetLifetimeReplicatedProps 함수에 새롭게 추가한 SecondAttribute들을 추가하였습니다.
