Unable to bind function to overlap event in C++

Development Programming & Scripting

I don’t know if this is because the methods I have looked up are depracated or I am simply missing something, but visual studio is telling me that the function I am trying to bind does not have the correct parameters. I have tried multiple different functions and would highly appreciate if someone pointed me in the right direction! Thank you in advance.

Header Declaration:

   UFUNCTION()
	void OnOverlapBegin(class AActor* l_otherActor, class UPrimitiveComponent* l_otherComp, int32 l_otherBodyIndex, bool l_fromSweep, const FHitResult& l_sweepResult);
	// Trigger collider used to help NPC characters interact with the door
	UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category = "Interactable", Meta = (AllowPrivateAccess = "true"))
	class UBoxComponent* m_boxTrigger = nullptr;

Implementation in Constructor:

// Create trigger box
	m_boxTrigger = CreateDefaultSubobject<UBoxComponent>(TEXT("TriggerCollider"));
	// Specify trigger collider definitions
	m_boxTrigger->SetupAttachment(m_objectMesh);
	m_boxTrigger->InitBoxExtent(FVector(100.0f, 100.0f, 100.0f));
	m_boxTrigger->SetRelativeLocation(FVector(0.0f, 60.0f, 100.0f));
	m_boxTrigger->SetCollisionProfileName("DoorTrigger");
	m_boxTrigger->SetCollisionResponseToChannel(ECollisionChannel::ECC_Pawn, ECollisionResponse::ECR_Overlap);
	// Bind overlap functions
	m_boxTrigger->OnComponentBeginOverlap.AddDynamic(this, &ADoor::OnOverlapBegin);

The function is also defined lower down in the .cpp.

I think you’re missing the first UPrimitiveComponent parameter. See below for en example

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

If you add that first component to your method signature (and your cpp of course), then it should work correctly.
