해결 방안

UPROPERTY() 매크로를 설정해주어야 GC 당하지 않는다

UPROPERTY()
UEquipmentState* EquipmentState;
UPROPERTY()
UMainState* MainState;
UPROPERTY()
USubState* SubState;

언리얼 엔진 5.1 문서 오브젝트 # 레퍼런스자동업데이트

  • AActor 또는 UActorComponent가 소멸되면 레퍼런스는 자동으로 null이 됩니다.
  • 이 기능은 UPROPERTY로 마킹되어 있거나 언리얼 엔진 컨테이너 클래스에 저장된 레퍼런스에만 적용됩니다. raw 포인터에 저장된 오브젝트 레퍼런스는 언리얼 엔진이 알지 못하기 때문에, 자동으로 null 되거나, 가비지 컬렉션이 방지되지 않습니다.
