How to let my gun shoot ??

var colpi : float;//colpi in totale

var tempo: float;//tempo tra un colpo e l'altro var colpo_fuori : GameObject;// copertura del proiettile var projectile : Rigidbody;// proiettile che esce dalla canna var Spawn1: Transform;// var Spawn2: Transform; // var Spawn3: Transform; // var Spawn4: Transform; //Le 6 zone dalle quali spara la mitragliatrice var Spawn5: Transform; // var Spawn6: Transform;// var Shoot_Bullet_Speed : int; // velocit dei proiettili

function Update () { if(Input.GetButtonDown("Fire1")) {//var clone1 : Rigidbody;//Per sparare clone1 = Instantiate(projectile, Spawn1.position, Quaternion.identity); clone1.AddForce(transform.forward*Shoot_Bullet_Speed);

//var clone2 : Rigidbody; clone2 = Instantiate(projectile, Spawn2.position, Quaternion.identity); clone2.AddForce(transform.forward*Shoot_Bullet_Speed);

 var clone5 : Rigidbody;//Per sparare
 clone5 = Instantiate(projectile, Spawn5.position, Quaternion.identity);
 clone5.AddForce(transform.forward*Shoot_Bullet_Speed);  

var clone6 : Rigidbody; clone6 = Instantiate(projectile, Spawn6.position, Quaternion.identity); clone6.AddForce(transform.forward*Shoot_Bullet_Speed);


} }
