Enemy stopped at first waypoints.

I wanna make enemy loop back to the first waypoints after it finished its patrol path. But somehow it stopped at the first waypoint. Basically didn’t even complete the first cycle. This is my code:

public class RedAlienMovement : MonoBehaviour
{
	private Waypoints wPoints;
	private int wPointsIndex;
        [SerializeField] private float speed;

	void Start()
	{
		wPoints = GameObject.FindGameObjectWithTag("Waypoints").GetComponent<Waypoints>();
	}

	void Update()
	{
		transform.position = Vector2.MoveTowards(transform.position, wPoints.waypoints[0].position, speed * Time.deltaTime);

		if (Vector2.Distance(transform.position, wPoints.waypoints[wPointsIndex].position) < 0.1f)
		{
			if (wPointsIndex < wPoints.waypoints.Length - 1)
			{
				wPointsIndex++;
			}
			else
			{
				wPointsIndex = 0;
			}
		}
}

Hello.

Some things:

FIrst, Maybe you should use NAVMESH system to move the enemies, it will help you with route calculation, speed, avoid obstacles, etc… And simplificate assign new target.

Second, Your problem is here:

transform.position = Vector2.MoveTowards(transform.position, wPoints.waypoints[0].position, speed * Time.deltaTime);

wPoints.waypoints[0] should be wPoints.waypoints[wPointsIndex]

Thats the original problem.

Bye!
