How To Make Enemy Shoot At You?

Hello, i want to make enemy shoot at me when it starts to follow me, im not sure but i think i should put the enemy shooting script in enemy AI script. What i am looking for is enemy shooting script, and where do i put it in enemy AI script.
Enemy AI:

var distance;

    var target : Transform;    

    var lookAtDistance = 15.0;

    var attackRange = 10.0;

    var moveSpeed = 5.0;

    var damping = 6.0;

    private var isItAttacking = false;

    function Update () 
    {
    distance = Vector3.Distance(target.position, transform.position);
    if(distance < lookAtDistance)
    {
    isItAttacking = false;
    renderer.material.color = Color.yellow;
    lookAt ();
    }   
    if(distance > lookAtDistance)
    {
    renderer.material.color = Color.green; 
    }
    if(distance < attackRange)
    {
    attack ();
    }
    if(isItAttacking)
    {
    renderer.material.color = Color.red;
    }
}
function lookAt ()
{
var rotation = Quaternion.LookRotation(target.position - transform.position);
transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * damping);
}
function attack ()
{
    isItAttacking = true;
    renderer.material.color = Color.red;
    transform.Translate(Vector3.forward * moveSpeed *Time.deltaTime);
}

//Enemy.js

public var Target : Transform;    
public var Projectile : Transform;

public var MaximumLookDistance : float = 15;
public var MaximumAttackDistance : float = 10;
public var FollowSpeed : float = 5;
public var MinimumDistanceFromPlayer : float = 2;

public var RotationDamping : float = 6;

function Update ()  {

    var distance = Vector3.Distance(Target.position, transform.position);

    if(distance <= MaximumLookDistance) {
        LookAtTarget ();

        if(distance <= MaximumAttackDistance)
            AttackAndFollowTarget (distance);
    }   
    else
        renderer.material.color = Color.green; 
}


function LookAtTarget () {
    renderer.material.color = Color.yellow;
    var dir = Target.position - transform.position;
    dir.y = 0;
    var rotation = Quaternion.LookRotation(dir);
    transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * Damping);
}


function AttackAndFollowTarget (distance : float) {
    renderer.material.color = Color.red;
    if(distance > MinimumDistanceFromPlayer)
        transform.Translate((Target.position - transform.position).normalized * MoveSpeed * Time.deltaTime);

    Instantiate(Projectile, transform.position + (Target.position - transform.position).normalized, Quaternion.LookRotation(Target.position - transform.position));
}

//Projectile.js

function Update () {
    transform.Translate(transform.forward);
}

function OnCollisionEnter (c : Collision) {
    //if(c.collider.CompareTag("Player"))
        //c.collider.gameObject.GetComponent(PlayerScript).Damage();

    Destroy(gameObject);
}

In function attack() if isItAttacking is true then instantiate a prefab (ex. a sphere) from the enemy position and add forward speed to your sphere or use a raycast…if the ray intersects your player then use instantiate again.
