Interrupt a MoveTowards when triggering

Questions & Answers
1

Hi everyone,
I’m trying to make a MoveTowards movement to be interrupted, when moving object enters in a trigger area.
The MoveTowards function in triggered by a first trigger when player is approaching enemy. Then, when enemy is close to player, a second trigger plays an animation. And I want the MoveTowards movement to be interrupted when enemy is inside 2nd trigger area.

Here is the code of my script attached to enemy :

public class HitBoxPlayer : MonoBehaviour
{
    public Animator animator;
    public Transform stopPosition;
    private EnemyAI triggeredBool;

    void Start()
    {
        animator = GetComponent<Animator>();
        stopPosition = GetComponent<Transform>();
    }

    void OnTriggerEnter2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "PlayerHitBox")
        {
            animator.SetTrigger("Push");
        }
    }

    void OnTriggerStay2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "PlayerHitBox")
        {
            animator.SetFloat("Moving", 0);
        }
    }

    void OnTriggerExit2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "PlayerHitBox")
        {
            animator.ResetTrigger("Push");
        }
    }

    void Update()
    {
    }
}

And here is the code for enemy movement :

public class EnemyAI : MonoBehaviour
{
    public float speed;
    public Transform target;
    public Animator animator;
    public bool triggered = false;
    private bool facingRight = false;

    void Start()
    {
        target = GameObject.FindGameObjectWithTag("Player").GetComponent<Transform>();
    }

    void OnTriggerStay2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "Player")
        {
            triggered = true;
            if (triggered == true)
            {
                transform.position = Vector2.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
                animator.SetFloat("Moving", Mathf.Abs(speed));
            }
        }
    }

    void Update()
    {
        if (target.transform.position.x < gameObject.transform.position.x && facingRight)
            Flip();
        if (target.transform.position.x > gameObject.transform.position.x && !facingRight)
            Flip();
    }

    void Flip() //function used to make enemy flip left/right
    {
        facingRight = !facingRight;
        Vector3 tmpScale = gameObject.transform.localScale;
        tmpScale.x *= -1;
        gameObject.transform.localScale = tmpScale;
    }

    void OnTriggerExit2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "Player")
        {
            animator.SetFloat("Moving", 0);
            triggered = false;
        }
    }
}

I tried to make triggered function false by calling it inside HitBoxPlayer, but nothing so far. Also tried to get enemy position and T instant and to make a transform.position with thoses data, neither.

Thanks to anyone who can find out an answer.

First of all your triggered variable doesn’t actually do anything from what I can tell.

Secondly you could achieve what you’re looking for by calculating the distance between the player and the enemy only execute MoveTowards as long as the distance is higher than some threshold. Once the enemy is closer than the threshold you would just not move it:

     void OnTriggerStay2D(Collider2D other)
     {
         if (other.GetComponent<Collider2D>().tag == "Player")
         {
             if (distance > threshold)
             {
                 transform.position = 
                     Vector2.MoveTowards(
                         transform.position, target.position, speed * Time.deltaTime);
                 animator.SetFloat("Moving", Mathf.Abs(speed));
             }
             else
             {
                 animator.SetFloat("Moving", 0);
             }
         }
     }

Thanks @IronBytes !
Here is my code with changes you suggested.

public class EnemyAI : MonoBehaviour
{
    public float speed;
    public Transform target;
    public Animator animator;
    private bool facingRight = false;
    public float threshold;
    private float distance;

    void Start()
    {
        target = GameObject.FindGameObjectWithTag("Player").GetComponent<Transform>();
    }

    void OnTriggerStay2D(Collider2D other) 
    {
        if (other.GetComponent<Collider2D>().tag == "Player")
        {
            if (distance > threshold)
            {
                transform.position = Vector2.MoveTowards(transform.position, target.position, speed * Time.deltaTime);
                animator.SetFloat("Moving", Mathf.Abs(speed));
                animator.SetBool("Push", false); //Change my trigger to a bool
            }
            else
            {
                animator.SetFloat("Moving", 0);
                animator.SetBool("Push", true);
            }
        }
    }

    void Update()
    {
        if (target.transform.position.x < gameObject.transform.position.x && facingRight)
            Flip();
        if (target.transform.position.x > gameObject.transform.position.x && !facingRight)
            Flip();
        distance = Vector3.Distance(target.position, transform.position);
    }

    void Flip()
    {
        facingRight = !facingRight;
        Vector3 tmpScale = gameObject.transform.localScale;
        tmpScale.x *= -1;
        gameObject.transform.localScale = tmpScale;
    }

    void OnTriggerExit2D(Collider2D other)
    {
        if (other.GetComponent<Collider2D>().tag == "Player")
        {
            animator.SetFloat("Moving", 0);
            animator.SetBool("Push", false);
        }
    }
}
