I need to summon projectiles

Question

I cant figure out how to make the prefab instantiate facing the player, then fire.

     int randomO;
     float randomY;
     float randomX;
     public GameObject projectilePrefab;
     public Transform spawner;
     public Transform player;
     public float WaterSpeed;
 
     private float time;
     public float maxtime;
     // Start is called before the first frame update
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {
         randomO = Random.Range(1, 5);
         switch(randomO)
         {
             case 1:
                 randomY = 62.9f;
                 randomX = Random.Range(-83.9f, 83.1f);
                 break;
             case 2:
                 randomY = -66.8f;
                 randomX = Random.Range(-83.9f, 83.1f);
                 break;
             case 3:
                 randomX = -107.9f;
                 randomY = Random.Range(48.7f, -58.7f);
                 break;
             case 4:
                 randomX = 100.6f;
                 randomY = Random.Range(48.7f, -58.7f);
                 break;
         }
 
         transform.position = new Vector2(randomX, randomY);
 
         if (time <= 0.0f)
         {
             //Heres where i want to instantiate the object.
             time = maxtime;
         }
 
     }
 
     private void FixedUpdate()
     {
         if (time >= 0.0f)
         {
             time -= Time.deltaTime;
         }
     }

I didn't test that but I think you can rotate the prefab in the prefab mode then save then should work. Didn't test that but I think it should work.

Or if you want to change rotation via script maybe you can use

 public static Object Instantiate(Object original, Vector3 position, Quaternion rotation);

And set the rotation , something like this
Instantiate(cubePrefab, Vector3.zero, Quaternion.Euler(45, 0, 0));

I'd go with something like this:

          if (time <= 0.0f)
          {
              //Heres where i want to instantiate the object.
             GameObject myProjectile = Instantiate(projectilePrefab, spawner.position, spawner.rotation , spawner)
          myProjectile.transform.LookAt(player.position);
 
              time = maxtime;
          }

You could probably also do this by replacing spawner.rotation with player.rotation and multiplying that with some Quaternion to turn the game object the way you want.
