How to rotate the raycast on a patrolling enemy? (In front of the enemy at all times)

Questions & Answers

I am having trouble rotating my raycast (LineOfSite) on my enemy player. So when the enemy is patrolling the area. The player is able to steps on the ray cast, behind it because it set it up to point out left, and make them stop moving. Is it possible to flip the raycast like you flip the player? I tried transforming.Left and localscale and i end up getting errors.
NOTE: I am trying to keep the line in front of the enemy’s face

                movingLeft = true;
            }
        }
    }

    public void LineofSight()
    {
        RaycastHit2D enemyspoted = Physics2D.Raycast(transform.position, transform.forward, LosDis);
        if (enemyspoted.collider != null) {
            print("Player hit!");
            Debug.DrawLine(transform.position, enemyspoted.point, Color.red);
            TPlayer = GameObject.FindGameObjectWithTag("Player").GetComponent<Transform>();
            transform.position = Vector2.MoveTowards(transform.position, TPlayer.position, speed * Time.deltaTime);
            
        }else {
            Debug.DrawLine(transform.position, transform.position + Vector3.left * LosDis, Color.green);
        }


    }

I am guessing this is a side scroller. You might be able to use something like:

new Vector 2 (dir, 0)

instead of:

transform.forward

and set “dir” to -1 when looking left and to 1 when looking right.
