[UE4] BoxComponent Overlap C++ 사용

C++에서 BoxComponent나 CapsuleComponent같은 콜리전 충돌여부 함수

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

 

// CPP

ClassName::ClassName()
{
	m_pBoxComponent->OnComponentBeginOverlap.AddDynamic(this, &ClassName::OnOverlapBegin);
}

void ClassName::OnOverlapBegin(class UPrimitiveComponent* OverlappedComp, class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
	if (OtherActor && (OtherActor != this) && OtherComp) 
	{
		// ... 태그를 활용해서 구분해도 됨.
	}
}

그밖에 End도 존재
