Questions & Answers

I am moving a transform object but i need it to always face forwards. Any help appreciated. 

function Update ()
{
    if (activeTrail.length < 1)
    // If we have no positions in the trail, we have nothing to do in Update
    {
        return;
    }

    transform.position = Vector3.Lerp (transform.position, activeTrail [0], Time.deltaTime * speed);
    // Move towards the next position in the trail

    if (Vector3.Distance (transform.position, activeTrail [0]) < nearDistance)
    // If we have arrived at the next position in the trail, then...
    {
        activeTrail.Shift ();
        // ... remove that position from the trail - making the next on the list our new destination
        UpdateLine();
    }
}

You could use the transform.lookat() to easily have it face some specific world point - for example your next point on the trail
