Waiting for fractions of a Second

Question

I'm trying to make a laser that shoots 3 shots every 3 seconds(but with just a tiny delay between shots). I have got the laser shooting, but I don't understand how to add the delay to the shot. I tried using a delay method WaitForSeconds but it crashes the game(stuck in an infinite loop somehow?). amnt is preset to 3.

     private void fire(int amnt)
     {
         for(int x = 0; x < amnt; x++)
         {
             w$$anonymous$$le(!canShoot)
             {
                 //wait until timer goes
             }
             pos = gun.transform.position;
             Instantiate(laser, pos, Quaternion.LookRotation(player.transform.position - pos + new Vector3(0, 1.5f, 0)));
             canShoot = false;
             StartCoroutine(waitBetweenShots());
         }
     }
 
     IEnumerator waitBetweenShots()
     {
         yield return new WaitForSeconds(.1f);
         canShoot = true;
     }
 }

T$$anonymous$$s isn't going to work because you are starting 3 coroutines in the same frame. Additionally, unless your "wait until timer goes" comment is $$anonymous$$ding other code, that w$$anonymous$$le loop will be an infinite loop. Once you get into the w$$anonymous$$le loop, you cannot leave. T$$anonymous$$s is because coroutines are still executed on the main thread, just possibly at a later time. You cannot have a coroutine running simultaneously with your other code (well, you can, but there are a ton of limitations and generally it's not done). What you want is somet$$anonymous$$ng like t$$anonymous$$s:

 private void fire(int amount) {
     StartCoroutine(FireShots(amount));
 }
 
 private IEnumerator FireShots(int num){
     for (int i = 0; i < num; i++){
         pos = gun.transform.position;
         Instantiate(laser, pos, Quaternion.LookRotation(player.transform.position - pos + new Vector3(0, 1.5f, 0)));
         yield return new WaitForSeconds(.1f);
     }
 }
