	public Transform[] wayPoints;

	public int currentRoot;

	void Update () 
	{
		Vector3 pos = wayPoints[currentRoot].position;

		if(Vector3.Distance(transform.position, pos) < 0.5f)
		{
			currentRoot = (currentRoot < wayPoints.Length - 1) ? currentRoot + 1 : 0;
		}

		GetComponent<NavMeshAgent>().SetDestination(pos);
