UMovementComponent invalidation

Development Programming & Scripting C++

Hi!
I’ve created movement class and now trying to use it.


class CONTENT_API UMoveMotor : public UMovementComponent



class CONTENT_API ASteper : public AActor
...
	UPROPERTY(Category = Steper, VisibleAnywhere, BlueprintReadOnly)
	TSubobjectPtr<UMoveMotor> m_Motor;
...



ASteper::ASteper(const class FPostConstructInitializeProperties& PCIP)
	: Super(PCIP)
{
	m_Motor = PCIP.CreateDefaultSubobject<UMoveMotor>(this, TEXT("ShipMoveComponent"));

	if (!m_Motor)
		GEngine->AddOnScreenDebugMessage(-1, 20.0f, FColor::Red, TEXT("No Moving motor were constructed!"));

	PrimaryActorTick.bCanEverTick = true;
}
...
void ASteper::AddNewCoursePoint(FVector position)
{
	if (m_Motor != NULL)
		m_Motor->AddNewControlPoint(position);
	else
		GEngine->AddOnScreenDebugMessage(-1, 20.0f, FColor::Red, TEXT("No Moving motor"));
}

In ASteper constructor everything finy. But when I’m trying to call AddNewCoursePoint from parent Actor class (ASteper) it’s saying that m_Motor isn’t valid already.
Ticking of movement component keep going right.

What’s the problem? Why m_Motor became invalid?

The problem was in UPROPERTY() define. Remove it for TSubobjectPtr and it will be fine.
