Shooing and moving code

I am trying to move AND shoot (one bullet at a time) but what ends up happening is that I do either or, not both.

 using UnityEngine;
     using System.Collections;
     
     public class shootingscript : MonoBehaviour
     {
         public GUITexture guiShoot;
         public GUITexture guiLeft;
         public GUITexture guiRight;
         bool buttonShoot = false;
         bool buttonLeft = false;
         bool buttonRight = false;
     
         void ReadButtons ()
         {
             if (Input.touchCount > 0)
             {
                 // Get the touch info
             Touch t = Input.GetTouch(0);
                 
             // Did the touch action just begin?
             if (t.phase == TouchPhase.Began) { 
             if(guiShoot.HitTest (t.position))
                 Button ();
             if (guiLeft.HitTest (t.position))
                  buttonLeft = true;                      
             if (guiRight.HitTest (t.position))
                 buttonRight = true;
                 }
             // Did the touch end?
             if (t.phase == TouchPhase.Ended) {
             buttonLeft = false;
             buttonRight = false;
             buttonShoot = false;
             }
         }
  }
         void Update()
         {
         ReadButtons ();
         if (buttonRight){
     transform.Translate(Vector2.right * 4f *Time.deltaTime);
     transform.eulerAngles = new Vector2(0, 0);    
             }
             if (buttonLeft){
    transform.Translate(Vector2.right * 4f * Time.deltaTime);
     transform.eulerAngles = new Vector2(0, 180);
             }
             }
         void Button ()
     {
          WeaponScript weapon = GetComponent<WeaponScript>();
              if (weapon != null)
             {
             weapon.Attack(false);
             }
         }
     
     }
