How do you make a character flip in Unity 2d

I’m working on an enemy AI in unity 2d and I would like to make it always look at the player only on one axis (x-axis) and in a certain range.

My current code is:

void Chase()
{
    t = this.transform;

    if (Vector3.Distance(t.position, target.position) < detectDistance)
    {

        Vector3 vectorToTarget = target.position - transform.position;
        float moveDistance = moveSpeed * Time.deltaTime;
        if (vectorToTarget.magnitude > moveDistance)
        {
            transform.position = Vector2.MoveTowards(transform.position, new Vector2(target.position.x, transform.position.y), moveSpeed * Time.deltaTime);
        }
        else
        {
            transform.position = target.position;
        }
        if (target.position.x > transform.position.x && !facingRight)
            Flip();
        if (target.position.x < transform.position.x && facingRight)
            Flip();
        chasing = true;
        animation.SetBool("walking", false);
        animation.SetBool("running", true);
        animation.SetBool("idle", false);
    }
    else
    {
        chasing = false;
        animation.SetBool("walking", false);
        animation.SetBool("running", false);
        animation.SetBool("idle", true);
    }
}

I think that the could would go in the Flip function which is currently empty but I’m not sure.

voi FIip(){

Vector3 scale = transform.localScale;

scale.x = -scale.x;

transform.localScale = scale;

}
