Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Problems with custom Scene Component

Hello guys,

I want to create a custom (Scene Component) Camera Rig Component. I want it as a component because I don't want to have Camera Logic inside my ACharacter class. So I created UCameraRigComponent class that looks like this:

 UCLASS( ClassGroup=(Custom), meta=(BlueprintSpawnableComponent) )
 class THIRDPERSON_API UCameraRigComponent : public USceneComponent
     virtual void TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction) override;
     virtual void BeginPlay() override;
     UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, meta = (AllowPrivateAccess = "true"))
     class USceneComponent* Rig;
     UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, meta = (AllowPrivateAccess = "true"))
     class USceneComponent* Pivot;
     UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, meta = (AllowPrivateAccess = "true"))
     class USpringArmComponent* SpringArm;
     UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, meta = (AllowPrivateAccess = "true"))
     class UCameraComponent* Camera;

As you can see this CameraRig has 4 parts: 1. A USceneComponent called Rig that serves as the root of the component hierarchy. 2. Another USceneComponent called Pivot that is supposed to be a child of the Rig. 3. A USpringArmComponent SpringArm, it's the child of the Pivot. 4. And lastly a UCameraComponent Camera attached to the spring arm.

So when I add this component to an actor I want it to receive this hierarchy of components: ... Rig (Root) -> Pivot (Child of Rig) ->SpringArm (Child of Pivot) ->Camera (Child of SpringArm) ...

Here is the constructor:

     PrimaryComponentTick.bCanEverTick = true;
     this->Rig = CreateDefaultSubobject<USceneComponent>(TEXT("Rig"));
     this->Pivot = CreateDefaultSubobject<USceneComponent>(TEXT("Pivot"));
     this->SpringArm = CreateDefaultSubobject<USpringArmComponent>(TEXT("SpringArm"));
     this->Camera = CreateDefaultSubobject<UCameraComponent>(TEXT("Camera"));
     this->Camera->SetupAttachment(this->SpringArm, USpringArmComponent::SocketName);

It doesn't achieve the needed result. When I add my custom CameraRig component to an actor it doesn't receive the mentioned hierarchy of components. How can I achieve such a result?
