How to create an actorcomponent into an actor

Development Programming & Scripting C++

I need to create my actorcomponent into a character.
Tried through NewObject, but then everything crashes.

UMyActorComponent* MyComponent = NewObject<UActorComponent> (this, UActorComponent :: StaticClass (), TEXT (“MyCompoent”));
if (MyComponent)
{
MyComponent-> RegisterComponent ();
}

How can I attach ActorComponent to a character in C ++?

UActorComponent is abstract - you should be using your components class.

Try some other component first:


USphereComponent* SphereComponent = NewObject<USphereComponent>(this);

if (SphereComponent != nullptr)
{
   SphereComponent->SetSphereRadius(10.0f, false);
   SphereComponent->SetCollisionProfileName(UCollisionProfile::NoCollision_ProfileName);
   SphereComponent->AttachToComponent(this, FAttachmentTransformRules::SnapToTargetIncludingScale);
   SphereComponent->RegisterComponent();
   SphereComponent->SetVisibility(true);
   SphereComponent->SetHiddenInGame(false);
}

Also, where do you want to create this component?

If you’re creating this in the constructor, you use CreateOptionalDefaultSubobject:


USphereComponent* SphereComponent = ObjectInitializer.CreateOptionalDefaultSubobject<USphereComponent>(this);

if (SphereComponent != nullptr)
{
   SphereComponent->SetSphereRadius(10.0f, false);
   SphereComponent->SetCollisionProfileName(UCollisionProfile::NoCollision_ProfileName);
   SphereComponent->SetupAttachment(RootComponent);
   SphereComponent->SetVisibility(true);
   SphereComponent->SetHiddenInGame(false);
}

Thanks for your reply. Yes, I wanted to create it in the constructor. The second method worked.
