✅ Sword Attack시 데미지 처리가 2번 되는 버그

◼️ Bool Type 변수를 이용해 한 번만 처리
In Character Blueprint <SimpleAI>

• New Variable: CanBeHitWithMelee
  Type: Boolean
  Default Value: True
• Branch
  CanBeHitWithMelee == True ?
  True인 경우면 실행
  
• SimpleAi의 남은 health가 0보다 큰 경우
  → CanBeHitWithMelee False
  → Delay를 통해 일정 시간 후
  → CanBeHitWithMelee True
  

✅ Loot Bag Pick up 로직 추가

◼️ 기존 Magic Character 전용 로직 활용

• Box Component → On Component Begin Overlap
  → Cast to Sword Character
  ...
  

✅ 부자연스러운 애니메이션 보완

◼️ Animation State 수정
In Animation Blueprint <Sword_AnimBP>

• State Machine - Idle State 추가
• Idle State
  Final Animation Pose 결정
  sword_and_shield_idle
• Transition Rule
  - Idle → Movement: Speed > 10
  - Movement → Idle: Speed <= 10
  - Idle → Sword_Attack: SlashSword == True
  - Sword_Attack → SlashSword == False

◼️ 보간 시간 수정
In Blend Space <Walk_Run_BS>

• Horizontal/Vertical Axis - Interpolation Time: 1.0

✅ Result

• 조금 더 자연스러운 Animation 재생
