How do I make the enemy stop walking and shoot the player?

Question

The enemy still patrols while shooting if it sees the player

Patrolling Script

 public float moveSpeed;
 public bool moveRight;

 public Transform wallCheck;
 public float wallCheckRadius;
 public LayerMask whatIsWall;
 private bool hittingWall;

 private bool notAtEdge;
 public Transform edgeCheck;

void Start() {

 }

 // Update is called once per frame
 void Update()
 {
     hittingWall = Physics2D.OverlapCircle(wallCheck.position, wallCheckRadius, whatIsWall);

     notAtEdge = Physics2D.OverlapCircle(edgeCheck.position, wallCheckRadius, whatIsWall);

     if (hittingWall || !notAtEdge)
         moveRight = !moveRight;

     if (moveRight)
     {
         transform.localScale = new Vector3(-0.75f, 0.75f, 0.8f);
         GetComponent<Rigidbody2D>().velocity = new Vector2(moveSpeed, GetComponent<Rigidbody2D>().velocity.y);
     }

     else
     {
         transform.localScale = new Vector3(0.75f, 0.75f, 0.8f);
         GetComponent<Rigidbody2D>().velocity = new Vector2(-moveSpeed, GetComponent<Rigidbody2D>().velocity.y);

     }

Our "ShootAPlayerInRange" Script

 public float playerRange;

 public GameObject enemyBullet;

 public CharacterController2D player;

 public Transform launchPoint;

 public float waitBetweenShots;
 private float shotCounter;

  

 // Start is called before the first frame update
 void Start()
 {
     player = FindObjectOfType<CharacterController2D>();
     shotCounter = waitBetweenShots;


 }

 // Update is called once per frame
 void Update()
 {

     Debug.DrawLine(new Vector3(transform.position.x - playerRange, transform.position.y, transform.position.z), (new Vector3(transform.position.x + playerRange, transform.position.y, transform.position.z)));
     shotCounter -= Time.deltaTime;


     if (transform.localScale.x < 0 && player.transform.position.x > transform.position.x && player.transform.position.x < transform.position.x + playerRange && shotCounter < 0)
     {
         Instantiate(enemyBullet, launchPoint.position, launchPoint.rotation);
         shotCounter = waitBetweenShots;
     }


     

     if (transform.localScale.x > 0 && player.transform.position.x < transform.position.x && player.transform.position.x > transform.position.x - playerRange && shotCounter < 0)
     {
         Instantiate(enemyBullet, launchPoint.position, launchPoint.rotation);
         shotCounter = waitBetweenShots;
     }

 
 }

}

Here's one solution (not necessarily the best one):

In the ShootAPlayerInRange script:

Add the field public bool shootingAtPlayer

At the top of the Update method, add the code shootingAtPlayer = false;

In both If-statements, add the code shootingAtPlayer = true;

In the Patrolling script:

Add the field private ShootAPlayerInRange shootAPlayerInRageComponent

In the Start method, add the code:

 shootAPlayerInRageComponent = GetComponent<ShootAPlayerInRange>();

In the Update method, add an if-statement that sets the object's velocity to zero if shootAPlayerInRageComponent.shootingAtPlayer is true.

I would also recommend that you cache a reference to your Rigidbody2D. You are currently calling GetComponent every frame (twice even).
