[언리얼엔진] add dynamic overlap event

트리거 박스 만들기

 

//동적 이벤트는 UFUNCTION()을 써준다
UFUNCTION()

//오버라이드
void OnOverlapBegin(UPrimitiveComponent* OverlappedComp, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult);



//cpp에서 재정의
void APlatformTrigger::OnOverlapBegin(UPrimitiveComponent* OverlappedComp, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
//로그 출력
UE_LOG(LogTemp, Warning, TEXT("Actived"));
}

 

//BeginPlay()에서 오버랩시 호출할 함수를 델리게이트

//OnOverlapBegin을 해도 되고 직접 만든 함수를 넣어도 가능

TriggerVolume->OnComponentBeginOverlap.AddDynamic(this, &APlatformTrigger::OnOverlapBegin);

 

 

OnTriggerEnd 구현

 

//직접 함수 지정

UFUNCTION()
void MyOnOverlapEnd(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex);

 

//델리게이트 콜백지정

TriggerVolume->OnComponentEndOverlap.AddDynamic(this, &APlatformTrigger::MyOnOverlapEnd);

 

//직접 지정한 함수로

void APlatformTrigger::MyOnOverlapEnd(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex)
{
UE_LOG(LogTemp, Warning, TEXT("DePressed"));
}
