Hi there,

I have my custom UActorComponent, I want to add it to my character , Component will appear on editor under my character , but when I call m_grabComponent->DoStuff() it is NULL .
What I’m missing ? thanks.

// Sets default values for this component's properties
USGrabObjectComponent::USGrabObjectComponent()
	: m_bBlockFrontMovementNextTick(false)
	, m_bBlockRightMovementNextTick(false)
	, m_fGrabbingDistanceTreshold(10.f)
	, m_fYawClampValueGamepad(0.1f)
	, m_fYawClampValueMouse(1.f)
	, m_fLastSignGrabbingRightward(0.f)
	, m_fLastSignGrabbingForward(0.f)
	, m_bCanYaw(true)
	, m_bCanYawLeft(true)
	, m_bCanYawRight(true)
	, m_bCanMoveLeft(true)
	, m_bCanMoveRight(true)
	, m_bCanMoveForward(true)
	, m_bCanMoveBackward(true)

{
	// Set this component to be initialized when the game starts, and to be ticked every frame.  You can turn these features
	// off to improve performance if you don't need them.
	bWantsBeginPlay = true;
	PrimaryComponentTick.bCanEverTick = true;

	// ...
}
