Problem with objectpooling and getting NullReference Exception

This is my first post so I am sorry in advanced if i have laid this out poorly or posted it in the wrong section. I just tried to be as thorough and detailed as i could be.

I'm very new to unity and making a modified bullet hell game (thought I would set myself a challenge for my first game). I've so far managed to make a character and an object pool using an array for my projectiles, after I managed (albeit i really had to try) to get my frame rate under 1FPS, and decided against using simple instantiate/destroy.

I followed along with a tutorial on youtube to make an object pool and i can get it working exactly the same as he did (albeit it is an old tutorial using setActiveRecursively) the issue i am having is spawning (activating) the projectile at my players position. Currently i can only get it to spawn a 0,0,0.

Here is the code i am using: Projectile Code;

 ***using UnityEngine;
 using System.Collections;
 
 public class projectileTest : MonoBehaviour {
 
 
     public float life =2.0f;
     public float speed = 10.0f;
     private float timeToDie = 0.0f;
     private Transform myTransform;
 
 
     void Start()
     {
         myTransform = transform;
     }
 
     // Update is called once per frame
     void Update ()
     {
         Countdown ();
         Automove ();
     }
 
     public void Activate()
     {
         myTransform.position = Vector3.zero;
         timeToDie = Time.time + life;
 
     }
 
     private void Deactivate()
     {
         this.gameObject.SetActive(false);
     }
 
     private void Countdown()
     {
         if (timeToDie < Time.time)
         {
             Deactivate();
         }
     }
 
     private void Automove ()
     {
         Vector3 velocity = speed * Time.deltaTime * Vector3.up;
         myTransform.Translate(velocity);
     }
 }***

the script for the object pool.

 ***using UnityEngine;
 using System.Collections;
 
 public class objectPool : MonoBehaviour {
 
     GameObject[] projectiles;
     public int numOfProjectilesToCreate = 0;
 
     // Use this for initialization
     void Start () {
         projectiles = new GameObject[numOfProjectilesToCreate];
         InstantiateProjectiles ();
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetMouseButtonDown(0))
         {
             ActivateProjectile ();
         }
     }
 
     private void InstantiateProjectiles()
     {
         for (int i = 0; i < numOfProjectilesToCreate; i++)
         {
             projectiles[i] = Instantiate (Resources.Load ("projectiletest")) as GameObject;
             projectiles[i].SetActive (false);
         }
     }
 
     private void ActivateProjectile()
     {
         for (int i = 0; i < numOfProjectilesToCreate; i++)
         {
             if (projectiles[i].activeInHierarchy == false)
             {
             projectiles[i].SetActive(true);
             projectiles[i].GetComponent<projectileTest>().Activate();
             return;
             }
         }
     }
 }***

I have tried swapping out the Vector3.Zero for transform.position = new Vector3(playerPosition.transform.position.x,playerPosition.transform.position.y,1); after setting a new public variable in the inspector for playerPosition

I have also tried adding the same script at the end of the activate projectile function.

Been banging my head for 3 days trying to figure this one out, and i've exhausted every logical method my limited knowledge can muster. Every time i try and change the position of activation i get a NullReferenceException on the line when i try to set the x and y axis to playerPosition.

I'm sure the answer is glaringly obvious and i'm just missing it. So I thought the best place to ask was here.
