my ai wont move

hi, I'm having some trouble getting my ai to move. it will move without a collider but I need one to activate a script. anything will help. thanks in advance.

 public float Range = 10f;

 public Transform Target;

 bool detected = false;

 Vector2 direction;

 public float moveSpeed = 10f;

 private void Start()
 {
     
 }
 private void OnCollisionEnter2D(Collision2D coll)
 { 
    Destroy(this.gameObject);
 }

 private void FixedUpdate()
 {
     Vector2 targetpos = Target.position;

     direction = targetpos - (Vector2)transform.position;

     RaycastHit2D rayInfo = Physics2D.Raycast(transform.position, direction, Range);

     if (rayInfo)
     {
         if (rayInfo.collider.gameObject.tag == "Player")
         {
             if (detected == false)
             {
                 
                 detected = true;
             }
         }
     }
     if (detected == true)
     {
         transform.up = direction;
         transform.Translate(transform.up * moveSpeed * Time.deltaTime);
         Invoke("die", 3);
         
     }
 }
 public void die()
 {
     Destroy(this.gameObject);
 }
 private void OnDrawGizmosSelected()
 {
     Gizmos.DrawWireSphere(transform.position, Range);
 }

} ,hi, I have a problem with getting my ai to have a collider and use this script. I am completely lost so anything will help. thanks in advance.
