Duplicating [this][1] question.

Hello everyone!

I have a character class with following constructor:

 ACharacter2D::ACharacter2D()
 {
     PrimaryActorTick.bCanEverTick = true;
 
     Capsule = CreateDefaultSubobject<UCapsuleComponent>(TEXT("RootCapsule"));
     Capsule->bGenerateOverlapEvents = true;
     Capsule->SetNotifyRigidBodyCollision(true);
     Capsule->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
     Capsule->SetCollisionObjectType(ECC_Pawn);
     Capsule->SetCollisionResponseToChannel(ECC_WorldStatic, ECR_Block);
     Capsule->SetCollisionResponseToChannel(ECC_WorldDynamic, ECR_Overlap);
     Capsule->SetCollisionResponseToChannel(ECC_Pawn, ECR_Overlap);
     Capsule->OnComponentHit.AddDynamic(this, &ACharacter2D::OnHit);
 
     RootComponent = Capsule;
 
     Movement = CreateDefaultSubobject<USimple2DMovement>(TEXT("2DMovement"));
     Movement->UpdatedComponent = RootComponent;
 
     AutoPossessPlayer = EAutoReceiveInput::Player0;
 }

Function OnHit, that is binded with OnComponentHit.AddDynamic, is defined as follows:

void ACharacter2D::OnHit(UPrimitiveComponent* HitComponent, AActor* OtherActor, UPrimitiveComponent* OtherComponent, FVector NormalImpulse, const FHitResult& Hit)
 {
     UE_LOG(LogClass, Warning, TEXT("Hit!"));
 }

I constructed test level with blocks consisting of simple square sprites with following collision properties:
216401-
Whatever I do, hit event just never triggers. I tried moveing my character with

MoveUpdatedComponent(DesiredMovement * DeltaTime, UpdatedComponent->GetComponentRotation(), true, &Hit, ETeleportType::None)

and

UpdatedComponent->SetLocation(UpdatedComponent->GetLocation()+ DesiredMovement * DeltaTime);

Tried dropping physics simulated object on my character, still no luck. Object gets blocked, event doesn’t occur.

Does anyone have any idea how to fix this?

In case someone has stumbled upon the same problem, I post solution here:

The OnHit function has to be binded to actor’s OnActorHit delegate, NOT component’s OnComponentHit delegate:

this->OnActorHit.AddDynamic(this, &ACharacter2D::OnHit);

And respectively OnHit function has to have different signature:

void OnHit(AActor* SelfActor, AActor* OtherActor, FVector NormalImpulse, const FHitResult& Hit);
