Begginer questions

Thanks for all your help You are the best!

I don't understand this method very well, but I created simple custom controller:

Code:

public class EnemyWagonController : SplineController
{
private float _tfValue;
private int _direction = 1;

void Awake()
{
Vector3 nearestPoint;
_tfValue = Spline.GetNearestPointTF (transform.localPosition, out nearestPoint);
transform.localPosition = nearestPoint;
}

public override void Refresh ()
{
Move ();
}

void Move()
{
Vector3 nearestPoint;
_tfValue = Spline.GetNearestPointTF (transform.localPosition, out nearestPoint);
transform.localPosition = Spline.MoveByLengthFast (ref _tfValue, ref _direction, 2f, CurvyClamping.PingPong);
}
}

And I assume MoveByLengthFast(ref float tf, ref int direction, float distance, CurvyClamping clamping) distance is speed, but how can I track my controller reached target distance?

Sorry for my stupid questions.
