OnComponentBeginOverlapNotWorking

[GloatingDevil]

hello i am trying to use the OnComponentBeginOverlap on my door component but its not working here are the code snippets

this is inside constructor

   Knob = CreateDefaultSubobject<UDynamicMeshComponent>(TEXT("Knob"));
    Knob->AttachToComponent(DynamicMeshComponent, 
    FAttachmentTransformRules::KeepRelativeTransform);
    Knob->OnComponentBeginOverlap.AddDynamic(this, &ADoor::OnKnobBeginOverlap);

This is my Function

void ParentClass::OnKnobBeginOverlap(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult& SweepResult)
{
    FVector A = OtherActor->GetVelocity();
    int final = A[0] + A[1] + A[2] / MassOfDoor;
    AddActorLocalRotation((FQuat::MakeFromEuler(FVector(0,0,90))), true, nullptr,ETeleportType::None);

}

Knob

Try this combination in the CDO:

Knob->SetGenerateOverlapEvents(true);
Knob->SetCollisionProfileName(FName(OverlapAll));
Knob->OnComponentBeginOverlap.AddDynamic(this, &ADoor::OnKnobBeginOverlap);

hi sorry for late reply its says : Knob->SetCollisionProfileName(FName(OverlapAll));
undeclared identifier OverlapAll

[GloatingDevil]

ok i fixed the above issue by static FName CollisionProfileName(TEXT(“OverlapAll”));
Knob->SetCollisionProfileName(CollisionProfileName);
but the original issue still remains

[GloatingDevil]

for some reason this works with main dynamicMeshComponent but not with the knob

[GloatingDevil]

Had to include UFUNCTION() before the definition of function in header file
like this

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

This will resolve the issue
