✅ Create Health Pickup Item

◼️ New Blueprint Class - Actor <HealthPickup>

• Add Component: ParticleSystem
  파티클 - 템플릿: 사용할 파티클 선택(P_Heal_Aura)
• Add Component: Box Trigger
  //충돌 체크에 사용

◼️ Actor Blueprint <HealthPickup> - Event Graph

• New Node: Event Actor BeignOverlap
  //이 액터가 다른 액터에 겹칠 때, 이벤트 발생
• Event Actor BeginOverlap → Cast to ThirdPersonCharacter
  //Overlap된 Other Object가 ThirdPersonCharacter이면 다음 실행
• ThirdPersonCharacter → Branch
  Branch_Condition: ThirdPersonCharacter_Health < 1 ?
  //ThirdPersonCharacter의 Health 변수가 1 미만이면 다음 실행
• Set ThirdPersonCharacter_Health
  Float(ThirdPersonCharacter_Health) + Float(0.2)
  
• Set ThirdPersonCharacter_Health → Branch
  Branch_Condition: ThirdPersonCharacter_Health > 1?
  //예외 처리: Health 값이 max 값을 초과한 경우, max 값으로 set
• Branch → Spawn Emitter at Location
  Location: ThirdPersonCharacter → GetActorLocation
  //true, false 모두 Particle 생성
• Destroy Actor
  타깃: self
  //모든 과정 이후 액터 소멸
  

✅ Result

• Health Pickup
  

• Health Pickup 효과 발동 후 소멸
