Object Pooling issue. GameObject instantiating 1 bullet instead of multiple bullets

Questions & Answers

So I have this GO which supposed to shoot multiple bullets everytime it changes its designated spot/position. Unfortunately, it only instantiates one bullet everytime it changes position. I’m using object pooling to instantiate the bullet. I think the issues here are my loops and coroutine but can’t still figure it out.

Here’s my messy code.
PLEASE TAKE NOTE: I didn’t include all the variables here but I declared everything in my actual code, so don’t worry about it.

public GameObject bullet;                                                                          void Start ()
	{
        // OBJECT POOLING RIGHT HERE!!!
		// To store pooledAmount of game objects once the game starts 
		pooledAmount = 50;
		bulletS = new List<GameObject> ();
		for (int i = 0; i < pooledAmount; i++) {
			GameObject obj = (GameObject)Instantiate (bullet);
			obj.SetActive (false);
			bulletS.Add (obj);
		}
               StartCoroutine  ("Pattern");
     }

IEnumerator Pattern ()
	{	
		// First Pattern Spot
		while (transform.position != patternSpot [0].position) {
			transform.position = Vector2.MoveTowards (transform.position, posXY, movementSpeed * Time.deltaTime);
			yield return null;
		}

		StartCoroutine ("Shoot", 1f);
		yield return new WaitForSeconds (3f);

		// Second Pattern Spot
		while (transform.position != patternSpot [1].position) {
			transform.position = Vector2.MoveTowards (transform.position, posXY1, movementSpeed * Time.deltaTime);
			yield return null;

		}

		StartCoroutine ("Shoot", 1f);
		yield return null;
}

IEnumerator Shoot () {
		//Don't pool any game objects that is already active
		for (int i = 0; i < bulletS.Count; i++) {
		if (bulletS *!= null) {*

_ if (!bulletS .activeInHierarchy) {_
_ bulletS .transform.position = transform.position;
bulletS .transform.rotation = transform.rotation;
bulletS .SetActive (true);
* break;
}
} yield return new WaitForSeconds (.1f);
}
}*_

Is the Shoot() method supposed to activate more than one bullet? If so, you should remove the break in line 45 that exits the loop after the first bullet creation.

I don’t know how many bullets you want to create each time. You maybe want a second counter to break if for example 5 bullets have been created.

 IEnumerator Shoot () {
     //Don't pool any game objects that is already active
     int createdBullets = 0;
     for (int i = 0; i < bulletS.Count; i++) {
         if (bulletS *!= null) {*

if (!bulletS .activeInHierarchy) {
bulletS .transform.position = transform.position;
bulletS .transform.rotation = transform.rotation;
bulletS .SetActive (true);
if (++createdBullets == 5) break;
}
}
yield return new WaitForSeconds (.1f);
}
}
(I guess there is another part somewhere that disables the bullets again?)
