추가한 부분

• Weapon Component를 검증된 Get으로 변경한 이유는?
  • 적의 경우 없는 경우도 있기 때문에 검증된 Get으로 변환하여 유효한지/유효하지않은지 구분하여 사용한다.

Skill_Arrow

 

 

 

Destroy Actor로 삭제하면 Weapon_Bow 블루프린트의 변수 Arrows(Skill Arrow 배열)는 NULL이어서 Dangling Pointer가 될까? 만약 그렇다면 어떻게 지워줄까?

 

Yes. Dangling Pointer가 된다. 그래서

• Skill_Arrow 블루프린트에 End Play 이벤트를 만들어준다.
• Weapon_Bow 블루프린트에 OnArrowDestroyed를 만들어준다.
