How do I stop pathfinding after my enemy is dead?

Unity Engine

I tried to put the IsAlive pool in both the scripts but this didn’t work. I don’t know what I’m doing wrong. Any help is appreciated!

//script to make the enemy follow the player
public class EnemyAI : MonoBehaviour
{
    public Animator animator;
    [Header("Pathfinding")]
    public Transform target;
    public float activateDistance = 50f;
    public float pathUpdateSeconds = 0.5f;

    [Header("Physycs")]
    public float speed = 200f;
    public float nextWaypointDistance = 3f;

    [Header("Custom Behaviour")]
    public bool followEnabled = true;
    public bool directionLookEnabled = true;

    private Path path;
    private int currentWaypoint = 0;
    bool isGrounded = false;
    Seeker seeker;
    Rigidbody2D rb;



    public void Start()
    {
        seeker = GetComponent<Seeker>();
        rb = GetComponent<Rigidbody2D>();

        InvokeRepeating("UpdatePath", 0f, pathUpdateSeconds);

    }




    private void FixedUpdate()
    {
        if (TargetInDistance() && followEnabled)
        {
            PathFollow();
        }

    }

    private void UpdatePath()
    {
        if (followEnabled && TargetInDistance() && seeker.IsDone())
        {
            seeker.StartPath(rb.position, target.position, OnPathComplete);
        }
    }

    private void PathFollow()
    {
        if (path == null)
        {
            return;
        }

        if (currentWaypoint >= path.vectorPath.Count)
        {
            return;
        }

        isGrounded = Physics2D.Raycast(transform.position, -Vector3.up, GetComponent<Collider2D>().bounds.extents.y);

        Vector2 direction = ((Vector2)path.vectorPath[currentWaypoint] - rb.position).normalized;
        Vector2 force = direction * speed * Time.deltaTime;

        rb.AddForce(force);

        float distance = Vector2.Distance(rb.position, path.vectorPath[currentWaypoint]);
        if (distance < nextWaypointDistance)
        {
            currentWaypoint++;
        }

        if (directionLookEnabled)
        {
            if (rb.velocity.x > 0f)
            {
                transform.localScale = new Vector3(-1f * Mathf.Abs(transform.localScale.x), transform.localScale.y, transform.localScale.z);
            }

            else if (rb.velocity.y < 0.05f)
            {
                transform.localScale = new Vector3(Mathf.Abs(transform.localScale.x), transform.localScale.y, transform.localScale.z);
            }
        }
    }

    private bool TargetInDistance()
    {
        return Vector2.Distance(transform.position, target.transform.position) < activateDistance;
    }

    private void OnPathComplete(Path p)
    {
        if (!p.error)
        {
            path = p;
            currentWaypoint = 0;
        }
    }

    void Update()
    {
        bool followEnabled = EnemyHealth.IsAlive;
        animator.SetFloat("Speed", Mathf.Abs(speed));
    }

//script that manages the Die() function and the enemy health
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyHealth : MonoBehaviour
{
    public Animator animator;

    public int maxHealth = 100;
    int currentHealth;

   public static bool IsAlive = true;
 
    void Start()
    {
        currentHealth = maxHealth;

        IsAlive = true;
    }

    public void TakeDamage(int damage)
    {
        currentHealth -= damage;

        animator.SetTrigger("Hurt");

        if(currentHealth <= 0)
        {
            Die();
        }
 
    }

    void Die()
    {
        Debug.Log("Enemy died");

        animator.SetBool("IsDead", true);

        IsAlive = false;

        GetComponent<Collider2D>().enabled = false;
        this.enabled = false;

    }
}

Remove the EnemyAI component in Die()

Hi, sorry where is the enemy AI component?

or simply add "if (!IsAlive) return " to the first line of your fixed update, although Id also set the navmesh agent to not enabled. (either by isstopped or enable)

This worked! Thank you so much!

Right here

public class EnemyAI : MonoBehaviour
