public class AIController : MonoBehaviour

private int index;
private bool isRunning = false;
private float tolerance = 0.5f;

            void Start()

            void Update()

                if (!isRunning)
                {
                    StartCoroutine(MoveCommand(transform, points));

                {
                    var nextPoint = points[index];
                    transform_.position = Vector3.MoveTowards(transform_.position, nextPoint, (1 * Time.deltaTime));
        
                    while (!IsPointReached(transform_, nextPoint, tolerance))
                    {

                index = 0;
                yield break;
            }
        
            private bool IsPointReached(Transform transform_, Vector3 destiny, float tolerance)
                => ((transform_.position.x <= (destiny.x + tolerance) &&
                    transform_.position.x >= (destiny.x - tolerance)) &&
                    (transform_.position.y <= (destiny.y + tolerance) &&

Hi everyone!

So I want to move my transform through a list of points. Initially this script works fine, the transform goes to points[0], then to points[1] and finally points[2]. The coroutine ends and it’s run again, but this time, for some reason it ommits points[0], and it bounces between points[1] and points[2]

Can someone explain me why?
