ProjectA - ChangeCamera 에러 수정(2023/12/26)

현재 카메라 시점을 바꾸는 코드는 이렇다.

void APACharacterPlayer::SetChangeCamera()
{
	ensure(FpsCamera);
	ensure(TpsCamera);
	if (IsValid(TpsCamera) && IsValid(FpsCamera))
	{
		switch (CameraType)
		{
		case ECAMERA::TPS:
			TpsCamera->Activate();
			FpsCamera->Deactivate();
			MyCamera = TpsCamera;
			break;
		case ECAMERA::FPS:
			TpsCamera->Deactivate();
			FpsCamera->Activate();
			MyCamera = FpsCamera;
			break;
		}
	}
	else
	{
		UE_LOG(LogTemp, Error, TEXT("ERROR"));
	}
}

 

여기서 TpsCamera가 nullptr로 잡히는 버그가 발생했다.

그렇기에 여러가지 시도를 해보았지만 너무 허탈했다..

 

	// ThirdCamera
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UCameraComponent> TpsFollowCamera;

	// FirstCamera
	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UCameraComponent> FpsFollowCamera;

헤더파일에서 변수 이름을 바꿔줘야한다...

TpsCamera라는 변수이름이 언리얼엔진 어디에서 사용하고 있나보다....

진짜... 이것을 몇시간 째 삽질을 했는지.....일단 해결했으니 다행이다...

 

그래서 다시 좀 수정해보았다.

 

 

PACharacterPlayer.h

UENUM()
enum class ECAMERA : uint8
{
	TPS,
	FPS,
	COUNT,
};


UCLASS()
class PROJECTA_API APACharacterPlayer : public APACharacterBase
{

    ...


	UPROPERTY(EditAnywhere, BlueprintReadOnly, Category = Camera, Meta = (AllowPrivateAccess = "true"))
	ECAMERA CameraType;

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, Meta = (AllowPrivateAccess = "true"))
	TMap<ECAMERA, TObjectPtr<class UCameraComponent>> CameraMap;

	UPROPERTY(VisibleAnywhere, BlueprintReadOnly, Category = Camera, Meta = (AllowPrivateAccess = "true"))
	TObjectPtr<class UCameraComponent> MyCamera;
    
    ...
    
}

 

카메라 변수를 수정 TMap으로 담는다.

CameraType에 따라 바꾸도록하자.

PACharacterPlayer.cpp

APACharacterPlayer::APACharacterPlayer()
{

	// Camera
	UCameraComponent* TpsFollowCamera = CreateDefaultSubobject<UCameraComponent>(TEXT("TpsFollowCamera"));
	TpsFollowCamera->SetupAttachment(CameraBoom, USpringArmComponent::SocketName);
	TpsFollowCamera->bUsePawnControlRotation = false;

	UCameraComponent* FpsFollowCamera = CreateDefaultSubobject<UCameraComponent>(TEXT("FpsFollowCamera"));
	FpsFollowCamera->SetupAttachment(GetMesh(), TEXT("FX_Head"));
	FpsFollowCamera->bUsePawnControlRotation = true;
	FpsFollowCamera->SetRelativeRotation(FRotator(180.f, 0.f, 0.f));

	FpsFollowCamera->SetAutoActivate(false);

	CameraMap.Emplace(ECAMERA::TPS, TpsFollowCamera);
	CameraMap.Emplace(ECAMERA::FPS, FpsFollowCamera);

	CameraType = ECAMERA::TPS;
	MyCamera = CameraMap[CameraType];
}

void APACharacterPlayer::BeginPlay()
{
	Super::BeginPlay();
	...
	SetChangeCamera();
}

void APACharacterPlayer::SetChangeCamera()
{
	CameraType = CameraType == ECAMERA::TPS ? ECAMERA::FPS : ECAMERA::TPS;
	MyCamera->Deactivate();
	MyCamera = CameraMap[CameraType];
	MyCamera->Activate();
}

 

1인칭 카메라는 흔들리지 않도록 bUsePawnControlRotation = true로 바꿔주자

 

 

잘된다.
