Shots on loop

Hi guys,

I have this script attached to the boss, but it's shooting only when I press mouse, and I would like to put it in the loop to shoot 2times per second, how could I do it?

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4.  
5. public class EnemiesShots : MonoBehaviour
6. {
7.     public float speed;
8.  
9.     public GameObject shot;
10.     public Transform shotSpawn;
11.     public float fireRate;
12.  
13.     private float nextFire;
14.  
15.     void Update ()
16.     {
17.         if (Input.GetButton("Fire1") && Time.time > nextFire)
18.         {
19.             nextFire = Time.time + fireRate;
20.             Instantiate(shot, shotSpawn.position, shotSpawn.rotation);
21.         }
22.     }
23.  
24. }

 

I found out, If I remove "Input.GetButton("Fire1") &&" it works
