HellooooooooO!
I have a character, with a camera component. The actual player which spawns is a blueprint child of this c++ class, however the camera component is not being inherited!
in header:
UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, meta = (AllowPrivateAccess = "true"))
class UCameraComponent* FirstPersonCameraComponent;
FirstPersonCameraComponent = CreateDefaultSubobject<UCameraComponent>(TEXT("FirstPersonCamera"));
FirstPersonCameraComponent->SetupAttachment(GetCapsuleComponent());
FirstPersonCameraComponent->RelativeLocation = FVector(-39.56f, 1.75f, 64.f); // Position the camera
FirstPersonCameraComponent->bUsePawnControlRotation = true;
(My C++ code has all compiled successfully)
But in my blueprint child class, it has no such component:
What is going on?
EDIT:
I nailed down on the source of the problem, my entire constructor isn’t being called, here’s my source:

// Default offset from the character location for projectiles to spawn
GunOffset = FVector(100.0f, 30.0f, 10.0f);

I noticed that NONE of the components are being added, so i concluded that the constructor isn't working. Can you see anything wrong with it?
