How can I fire multiple projectiles at once?

I’m making a first person shooter, and I want to make it so that the shotgun fires 2 bullets/darts at once, the problem is, the darts are always facing the same direction, even if I shoot in another, and sometimes, it just freezes in mid-air, sometimes, it stutters in mid-air.

Here’s my code:

using UnityEngine;
using System.Collections;

public class ObjectPool : MonoBehaviour {
	
	GameObject[] projectiles;
	public GameObject projectileToCreate;
	public int numberOfProjectilesToCreate;
	public RayShoot gunScript;
	
	public float spread;
	public byte spreadAmount;
		
	public enum shootType
	{
		normal = 0,
		spread = 1,
		multiSource = 2
	}
	public shootType typeOfGun;
	public byte lifeSpan;
	
	// Use this for initialization
	void Start () 
	{
		projectiles = new GameObject[numberOfProjectilesToCreate];
		InstantiateProjectiles();
	}
	
	// Update is called once per frame
	void Update () 
	{
		if (gunScript.shooting)
		{
			Activate();
		}
	}
	
	private void InstantiateProjectiles()
	{
		for (int i = 0; i < numberOfProjectilesToCreate; i++)
		{
			Vector3 dartPosition = new Vector3 (transform.position.x, transform.position.y + Random.Range(-spread, spread),
							transform.position.z + Random.Range(-spread, spread)); 
			Quaternion dartRotation = Quaternion.Euler(transform.eulerAngles.x + Random.Range(-spread, spread), transform.eulerAngles.y +
							Random.Range(-spread, spread), transform.eulerAngles.z + Random.Range(-spread, spread));
			projectiles *= Instantiate(projectileToCreate, dartPosition, dartRotation) as GameObject;*

_ projectiles*.GetComponent().speed += Random.Range(-spread, spread);_
_ projectiles.SetActiveRecursively(false);
 }
 }*_

* private void Activate()*
* {*
* for (int s = 0; s < spreadAmount; s++)*
* {*
* for (int i = 0; i < numberOfProjectilesToCreate; i++)*
* {*
_ if (!projectiles*.active)
{
projectiles.transform.position = new Vector3 (transform.position.x, transform.position.y + Random.Range(-spread, spread),
transform.position.z + Random.Range(-spread, spread));
projectiles.transform.rotation = Quaternion.Euler(transform.eulerAngles.x + Random.Range(-spread, spread), transform.eulerAngles.y +
Random.Range(-spread, spread), transform.eulerAngles.z + Random.Range(-spread, spread));
projectiles.SetActiveRecursively(true);
projectiles.GetComponent().Activate();
return;
}
}
}
}
}
}
}
-----------------------------------------------------------*
using UnityEngine;
using System.Collections;_

public class ProjectileScript : MonoBehaviour {

* public float lifeSpan;*
* public float speed;*
* private float timeToDie;*

* // Use this for initialization*
* void Start ()*
* {*

* }*

* // Update is called once per frame*
* void Update ()*
* {*
* CountDown();*
* //AutoMove();*
* }*

* public void Activate()*
* {*
* timeToDie = Time.time + lifeSpan;*
* transform.position = Vector3.zero;*
_ Vector3 velocity = speed * Time.deltaTime * transform.forward;
* transform.Translate(velocity);
}*_

* private void Deactivate()*
* {*
* this.gameObject.SetActive(false);*
* }*

* private void CountDown()*
* {*
* if (timeToDie < Time.time)*
* {*
* Deactivate();*
* }*
* }*
}

How do I fix this?

transform.rotation is Quaternion. You are seeding your dartRotation Quaternion from Euler angles, however you are randomizing off of components of the Quaternion.

So you probably intended:

Quaternion dartRotation = Quaternion.Euler(transform.eulerAngles.x + Random.Range(-spread, spread), transform.eulerAngles.y +
                 Random.Range(-spread, spread), transform.eulerAngles.z + Random.Range(-spread, spread));
