Spawning enemies with Prefab script values

Question

I just wanted to ask if you can Instantiate a Prefab with the prefabs own script values. I have a Character stat class in an enemy and I am trying to make the Stats go up when a spesific time is passed.

 public class Stat
     {
         public int BaseValue;
         private int Value;
 
     public int GetValue()
     {
         return Value;
     }

     public void SetValue(int value)
     {
         Value = value;
     }

     public void AddValue(int value)
     {
         Value += value;
     }
 }
   public class CharacterStats:MonoBehaviour
     {
         private int Health;
         private int CurrentHealth;
         public int BaseHealth = 100;
         public Stat Damage;
         public Stat Agility;
         public Stat Vitality;
         void Awake()
         {
             Damage.SetValue(Damage.BaseValue);
             Agility.SetValue(Agility.BaseValue);
             Vitality.SetValue(Vitality.BaseValue);
             Health = BaseHealth * Vitality.GetValue();
             CurrentHealth = Health;
         }
         void start()
         {
             
         }
 
         void update()
         {
         }
         public void TakeDamage(int damage)
         {
             CurrentHealth-=damage;
         }
 
         public int GetCurrentHealth()
         {
             return CurrentHealth;
         }
 
         public int GetHealth()
         {
             return Health;
         }
     }

but when I am Instantiating the prefab it seems like it has its own values is there a way to force the prefabs values to the Instantiated object.

 public IEnumerator SpawnEnemy()
     {
         while (true)
         {
             var index = Random.Range(0, Enemies.Count);
             Instantiate(Enemies[index], transform.position, transform.rotation);
             
             yield return new WaitForSeconds(2);
         }
     }

There are a few ways to go about this, but you might find it helpful to have some sort of Initialize function on your enemies for this purpose.

 public void Initialize() // <-- add whatever values you need
 {
     // Assign those values
 }

which you'd then call within your spawner thing:

 public IEnumerator SpawnEnemy()
 {
     while (true)
     {
         var index = Random.Range(0, Enemies.Count);
         var enemy = Instantiate(Enemies[index], transform.position, transform.rotation);
 
         // Provide your values here
         enemy.Initialize();
 
         yield return new WaitForSeconds(2);
     }
 }

For the "make stats go up" part, you may also want to consider keeping a reference to whatever was spawned. That will make it a bit simpler to modify whatever enemies are still alive after a certain amount of time etc.

Coroutines don't return values, but you can pass a callback for when certain events happen to help with these things.

 public IEnumerator SpawnEnemy(System.Action<Enemy> onEnemySpawned)
 {
     while (true)
     {
         var index = Random.Range(0, Enemies.Count);
         var enemy = Instantiate(Enemies[index], transform.position, transform.rotation);
 
         // Provide your values here
         enemy.Initialize();
 
         onEnemySpawned?.Invoke(enemy);
 
         yield return new WaitForSeconds(2);
     }
 }
