C++ 코드에서 캐릭터 컴포넌트 설정 이유

안녕하세요. 강의 복습 중 궁금한 점이 있어서 질문 남깁니다.

CharacterBase 클래스의 생성자에서 Pawn과 Capsule Component, Movement Component, Skeletal Mesh Component 설정을 하고 있는데, 에디터에서 블루프린트에 직접 컴포넌트를 설정하는 것과 차이점이 무엇인지 궁금합니다.
차이가 없다면 왜 C++ 코드에서 이를 설정해주셨는지 알고 싶습니다.

{
 	// Pawn
    bUseControllerRotationRoll = false; // X
    bUseControllerRotationPitch = false; // Y
    bUseControllerRotationYaw = false; // Z

    // Capsule
    GetCapsuleComponent()->InitCapsuleSize(50.f, 100.f);
    GetCapsuleComponent()->SetCollisionProfileName(CPROFILE_HSCAPSULE);

    // Movement
    GetCharacterMovement()->bOrientRotationToMovement = true;
    GetCharacterMovement()->RotationRate = FRotator(0.f, 360.f, 0.f); // Pitch, Yaw, Roll
    GetCharacterMovement()->JumpZVelocity = 500.f;
    GetCharacterMovement()->AirControl = 0.35f;
    GetCharacterMovement()->MaxWalkSpeed = 500.f;
    GetCharacterMovement()->MinAnalogWalkSpeed = 20.f;
    GetCharacterMovement()->BrakingDecelerationWalking = 2000.f;

    // Mesh
    GetMesh()->SetRelativeLocationAndRotation(FVector(0.f, 0.f, -100.f), FRotator(0.f, -90.f, 0.f));
    GetMesh()->SetAnimationMode(EAnimationMode::AnimationBlueprint);
    GetMesh()->SetCollisionProfileName(TEXT("NoCollision"));
