My realization of closing the door

[MishaMouse]

Unlike the instructor, I have the closing and opening of the door in one function.

void UOpenDoor::MoveDoor(float DeltaTime)
{   
	CurrentYaw = FMath::FInterpTo(CurrentYaw, TargetYaw, DeltaTime, 2.f);
	FRotator DoorRotation = GetOwner()->GetActorRotation();
	DoorRotation.Yaw = CurrentYaw;
	GetOwner()->SetActorRotation(DoorRotation);
}

YawOffset variable is now responsible for turning Yaw.

private:
	float CurrentYaw, InitialYaw, TargetYaw;
	UPROPERTY()
	AActor* ActorThatOpens;
	
	UPROPERTY(EditAnywhere)
	float YawOffset = 90.f;
	
	UPROPERTY(EditAnywhere)
	ATriggerVolume* PressurePlate;

TargetYaw now changes depending on the result of the check in TickComponent.

// Called every frame
void UOpenDoor::TickComponent(float DeltaTime, ELevelTick TickType, FActorComponentTickFunction* ThisTickFunction)
{
	Super::TickComponent(DeltaTime, TickType, ThisTickFunction);

	if (PressurePlate && PressurePlate->IsOverlappingActor(ActorThatOpens))
	{
		TargetYaw = InitialYaw + YawOffset;
	}
	else
	{
		TargetYaw = InitialYaw;
	}
	
	MoveDoor(DeltaTime);
}
