Change Gun Fire Rate

Question

Hi, I am trying to make a gun shoot 14 bullets a second. I have tried many codes, but the only that will shoot at all. One will shoot one bullet every frame, and the other will shoot one bullet a second. My question is, what should my code be (in Javascript) to make a game object emit 14 bullets a second when I click the primary click button on my mouse.

My codes are:

this one shoots once per frame

 var bullet : GameObject;
 
 function Update(){
     if(Input.GetAxis("Fire1")){
     Instantiate(bullet, transform.position, transform.rotation);
     }
 
 }

This one shoots once per click

 var bullet : GameObject;
 
 function Update(){
     if(Input.GetButtonDown("Fire1")){
     Instantiate(bullet, transform.position, transform.rotation);
     }
 
 }

Here is an alternate solution of @cdrandin's that might be simpler for you to work with. It works by having a Shoot function that tries to fire ever 1/14 of a second, but will only fire if 'shooting' is set to true.

 #pragma strict
 
 var bullet : GameObject;
 var bulletsPerSecond = 14.0;
 private var shooting = false;
 
 function Start() {
    InvokeRepeating("Shoot", 0.0, 1.0 / bulletsPerSecond);
 }
 
 function Shoot() {
   if (!shooting) return;
   var go = Instantiate(bullet, transform.position, transform.rotation);
   go.rigidbody.AddRelativeForce(Vector3.forward * 1000.0);
 }
  
 function Update(){
     shooting = false;
     if(Input.GetAxis("Fire1")){
         shooting = true;
     }
 }

Note that this solution introduces an average lag between the time the fire button is hit to the shot fired of 0.035 seconds, but I don't think it would be noticed in game play.

Make a timer. Allow it to shot fireRate amount of time or you could use corountines, but making your own timer is just as simple.

 // Fire gun at the given fireRate. 
 //This is machine indepedent as it uses Time.DeltaTime
 timer += Time.DeltaTime
 if(timer > fireRate)
 {
     gun.fire()
     timer = 0 // reset timer for fire rate
 }
