Is there any way to empty the touch array.

hey, I'm creating a shooting game for mobile platform but i'm facing problem in touch.It is a shooting game so player have to press the button continuously,but after some time bullet creation is stop and if i leave the control for 1-2sec it start instantiate again.I'm using GUITexture for touch response. here is the code:-

`if (Input.touchCount > 0) {

   for (int i = 0; i < Input.touchCount; i++)
   {

     Touch touch = Input.GetTouch(i);
     if (touch.phase == TouchPhase.Began)
     {
       if(this.mJumpGUI.guiTexture.HitTest(touch.position)){    
     this.isclicked = true;
       }
       if (this.mFireGUI.guiTexture.HitTest(touch.position)){ 
          this.isPressed = true;
      this.isFired = false;
       }
     }
   }                        
 }
 //bullet code
 if (this.isPressed)
         {
             this.myAnimation.SetAnimation(2);
             if (this.myAnimation.GetCurrentFrame() == 2)
             {
                 if (!this.isFired)
                 {
                     this.CreateBullet(States.globalPSet._multibullet);
                     this.isFired = true;
                     this.mBulletFireTimer = (float)0;
                 }
             }
             else
             {
                 this.isFired = false;
             }
         }

 

 //bullet funtion
     public void CreateBullet(bool single)
     {
         this.PlaySound();
         checked
         {
             if (!single)
             {
                 GameObject gameObject = (GameObject)Instantiate(this.mBulletprefab, new Vector3(this.transform.position.x, unchecked(this.transform.position.y + 0.5f), this.transform.position.z), Quaternion.identity);
                 gameObject.rigidbody.AddForce(Vector3.up * this.mBulletSpeed, ForceMode.VelocityChange);
                 PlayerControl.mBulletList.Add(gameObject);
                     
             }
             else
             {
                 this.CreateMultiBullet();
                 
             }
         }
     }

this function is inside the update(), player have to press the button each time to create a bullet.
