Aiming a shot in Unity 2d?

Hello, I'm working on a 2d platformer project involving a grappling hook. I'm currently trying to script a basic projectile fired by the player. I followed a tutorial for doing so in a 2d shooter, using a shot prefab (with it's own "movement" and "shot" scripts) fired by a "WeaponScript" attached to the player character.

The problem is that this only fires the shot straight forward. I'd like for the shot to be fired in whatever direction the player character is facing, or whatever direction the player is holding on the game pad/keyboard.

Here is the weapon script attached to the player:

 using UnityEngine;
 
 
 public class WeaponScript : MonoBehaviour
 {
 
     public Transform shotPrefab;
 
     public float shootingRate = 0.25f;
     
 
     private float shootCooldown;
     
     void Start()
     {
         shootCooldown = 0f;
     }
     
     void Update()
     {
         if (shootCooldown > 0)
         {
             shootCooldown -= Time.deltaTime;
         }
     }
     
 
     public void Attack(bool isEnemy)
     {
         if (CanAttack)
         {
             shootCooldown = shootingRate;
             
             // Create a new shot
             var shotTransform = Instantiate(shotPrefab) as Transform;
             
             // Assign position
             shotTransform.position = transform.position;
             
             // The is enemy property
             ShotScript shot = shotTransform.gameObject.GetComponent<ShotScript>();
             if (shot != null)
             {
                 shot.isEnemyShot = isEnemy;
             }
             
             // Make the weapon shot always towards it
             MoveScript move = shotTransform.gameObject.GetComponent<MoveScript>();
             if (move != null)
             {
                 move.direction = this.transform.right; // towards in 2D space is the right of the sprite
             }
         }
     }
     
 
     public bool CanAttack
     {
         get
         {
             return shootCooldown <= 0f;
         }
     }
 }

I can tell the problem probably lies in the "move.direction = this.transform.right;" I have a function in my player character movement script that flips the sprite when moving in another direction, but I don't know how to flip this along with it.
