Summary

• How to add second and third combo attacks that only activate a short time after the previous attack input.
  
• Adding combos for heavy attacks, adjusting delay time ranges and fixing most issues and bugs! this also allows you to mix between attack types during a combo.

AstrumSensei

✅ Animation Import from Mixamo

◼️ Second,Third Light Attack Animation

• Second Light Attack → Light_Attack_2 검색어: Sword and Shield Slash

• Third Light Attack → Light_Attack_3 검색어: Standing Melee Attack 360

• Second Heavy Attack → Heavy_Attack_2 검색어: Great Sword Slash

• Third Heavy Attack → Heavy_Attack_3 검색어: Great Sword Kick

• Create Anim Montage

✅ Anim Notify

◼️ 공격 중 움직임 제어

• Anim Notify - Disable Movement, Enable Movement Skeleton Notify 이용 - Light_Attack_2_Montage - Light_Attack_3_Montage - Heavy_Attack_2_Montage - Heavy_Attack_3_Montage

✅ Light Attack Logic

◼️ Combat Graph In Character BP <BP_Base>

• Input Action Light Attack → Do Once 노드가 처음 걸릴 때만 출력이 발동하지만, 리셋 가능합니다 공격 입력 후 특정 시간이 지난 후에 다시 작동하도록 하는 역할
• New Variable: AttackCount (Int, 0) 현재 몇 번째 LightAttack인지 나타내는 변수
• Play Montage - Montage to Play → Select Node - Option0: Light_Attack_1 - Option0: Light_Attack_2 - Option0: Light_Attack_3 - Index: AttackCount → %(3) AttackCount를 3으로 나눈 나머지 값을 Index로 사용
• Switch On Int - Selection: AttackCount → %(3) AttackCount를 3으로 나눈 나머지 값을 Selection으로 사용

◼️ Switch Case: 0 첫 번째 Light Attack

• Increment Int - Attack Count 현재 Attack Count에 +1
• Delay 현재 재생 중인 몽타주의 재생 시간에 맞춰서 설정
• Sequence Then 0: Dealy-Duration 이후 DoOnce-Reset 입력에 연결하여 다음 공격 로직 실행 가능하도록 함 Then 1: Delay 이후 Attack Count를 0으로 초기화시킴
• Delay Duration 이후 Attack Count 초기화 로직
• Branch - AttackCount <=1 ? True → Set AttackCount 0 현재 AttackCount 값이 1 이하인 경우에만 0으로 초기화 'AttackCount 값이 1 이하?' 다음 공격이 진행 중이 아니라는 의미

◼️ Switch Case: 1 두 번째 Light Attack

• Increment Int - Attack Count
• Delay
• Sequence Then 0: DoOnce-Reset에 연결
• Delay
• Set AttackCount 0 다음 공격이 끝이기 때문에 Light Attack 3와 다르게 Branch 로직 없음

◼️ Switch Case: 2 세 번째 Light Attack

• Set AttackCount 0
• Delay 다음 콤보 공격이 존재하지 않기 때문에 AttackCount만 초기화 시킴 공격할 동안은 입력을 받지 않도록 하고, DoOnce-Reset 입력에 연결

✅ Heavy Attack Logic

◼️ Combat Graph

• Light Attack과 똑같은 로직으로 구현
• AttackCount를 공유함으로써, 콤보를 섞어서 사용 가능하게 함

✅ Result

• Light Attack 1
• Heavy Attack 2
• Light Attack 3

Summary
Adding light and heavy attacks based on two different inputs. similar to Dark Souls, God of War and other action RPG and melee games.

Play Montage, Play Anim Montage 비교
핵심 차이점

• Play Montage는 Skeletal Mesh Component에 직접 애니메이션을 재생
• Play Anim Montage는 Character의 AnimInstance에 의해 애니메이션 몽타주를 재생
  요약
• Play Montage는 더 단순한 방식으로, 특정 Skeletal Mesh에 애니메이션 몽타주를 재생하고, 캐릭터 관련 상태나 애니메이션 시스템에 의존하지 않습니다.
• Play Anim Montage는 캐릭터의 AnimInstance를 통해 애니메이션을 관리하고, 캐릭터의 상태와 관련된 추가적인 처리가 필요할 때 사용됩니다.

✅ Animation
