    {
        path = new NavMeshPath();
        elapsed = 0.0f;
    }    void Update()
    {
        // Update the way to the goal every second.
        elapsed += Time.deltaTime;
        if (elapsed > 1.0f)
        {
            elapsed -= 1.0f;
            NavMesh.CalculatePath(transform.position, target.position, NavMesh.AllAreas, path);
        }
        for (int i = 0; i < path.corners.Length - 1; i++)
            Debug.DrawLine(path.corners[i], path.corners[i + 1], Color.red);
