Using custom accelerometer, gyro & magnetometer to move objects

How do I make a player shoot right and left 2D platformer firing left and right, help! using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityStandardAssets.CrossPlatformInput;

public class movo : $$anonymous$$onoBehaviour { float bulletSpeed = 500f; public Animator anim; public Transform barrel; public Rigidbody2D bullet; private Rigidbody2D rb; private bool moveLeft; private bool moveRight; private float horizontal$$anonymous$$ove; public float speed = 5; public SpriteRenderer sp;

 private void Start()
 {
     anim = GetComponent<Animator>();
     rb = GetComponent<Rigidbody2D>();
     sp = GetComponent<SpriteRenderer>();
 
     moveLeft = false;
     moveRight = false;
 }
 
 public void PointerDownLeft()
 {
     anim.SetBool("run", true);
     moveLeft = true;
 }
 
 public void PointerUpLeft()
 {
     anim.SetBool("run", false);
     moveLeft = false;
 }
 
 public void PointerDownRight()
 {
     anim.SetBool("run", true);
     moveRight = true;
 }
 
 public void PointerUpRight()
 {
     anim.SetBool("run", false);
     moveRight = false;
 }
 
 void Update()
 {
     $$anonymous$$ovementPlayer();
     if (CrossPlatformInput$$anonymous$$anager.GetButtonDown ("Fire1"))
         Fire ();
 }
 
 void $$anonymous$$ovementPlayer()
 {
     if (moveLeft)
     {
         sp.flipX = true;
         horizontal$$anonymous$$ove = -speed;
     }
 
     else if (moveRight)
     {
         sp. flipX = false;
         horizontal$$anonymous$$ove = speed;
     }
 
     else
     {
         horizontal$$anonymous$$ove = 0;
     }
 }
 
 private void FixedUpdate()
 {
     rb.velocity = new Vector2(horizontal$$anonymous$$ove, rb.velocity.y);
 }

 void Fire()
 {
     var firedBullet = Instantiate (bullet, barrel.position, barrel.rotation);
     firedBullet.AddForce (barrel.up * bulletSpeed);
 }

}
