Movement help 2D Android HELP ME

Hello, guys i'm just trying to make some buttons for my player to move. but already animated a player and script to control it.. here my scripts

Controller: using System.Collections;

public class PlayerController : MonoBehaviour { public GUITexture left; public GUITexture right; public GUITexture up; public GUITexture down; public Vector2 moving = new Vector2();

 // Use this for initialization
 void Start () {
     
 }
 
 // Update is called once per frame
 void Update () {
     
     moving.x = moving.y = 0;

     if(Input.touchCount > 0 && Input.GetTouch(0)){


     
         if(right.HitTest(Input.touches[0].position)){
         
             moving.x = 1;
         }
         if(left.HitTest(Input.touches[0].position)){
         
             moving.x = -1;
     }
     
         if(up.HitTest(Input.touches[0].position)
         
             moving.y = 1;
         }
         if(down.HitTest(Input.touches[0].position){
         
             moving.y = -1;
     }
     
 }

}

I'm tired of trying to make it work guys please help me out

here the player script:

using UnityEngine; using System.Collections;

public class Player : MonoBehaviour {

 public float speed = 10f;
 public Vector2 maxVelocity = new Vector2(3, 5);
 public bool standing;
 public float jetSpeed = 15f;
 public float airSpeedMultiplier = .3f;
 public AudioClip leftFootSound;
 public AudioClip rightFootSound;
 public AudioClip thudSound;
 public AudioClip rocketSound;
 public Vector2 moving = new Vector2();
 private Animator animator;
 private Movimiento controller;
 
 void Start(){
     controller = GetComponent<Movimiento> ();
     animator = GetComponent<Animator> ();
 }
 
 void PlayLeftFootSound(){
     if (leftFootSound)
         AudioSource.PlayClipAtPoint (leftFootSound, transform.position);
 }
 
 void PlayRightFootSound(){
     if (rightFootSound)
         AudioSource.PlayClipAtPoint (rightFootSound, transform.position);
 }
 
 void PlayRocketSound(){
     if (!rocketSound || GameObject.Find ("RocketSound"))
         return;
     
     GameObject go = new GameObject ("RocketSound");
     AudioSource aSrc = go.AddComponent<AudioSource> ();
     aSrc.clip = rocketSound;
     aSrc.volume = 0.7f;
     aSrc.Play ();
     
     Destroy (go, rocketSound.length);
     
 }
 
 void OnCollisionEnter2D(Collision2D target){
     if (!standing) {
         var absVelX = Mathf.Abs(rigidbody2D.velocity.x);
         var absVelY = Mathf.Abs(rigidbody2D.velocity.y);
         
         if(absVelX <= .1f || absVelY <= .1f){
             if(thudSound)
                 AudioSource.PlayClipAtPoint(thudSound, transform.position);
         }
     }
     
 }
 
 // Update is called once per frame
 void Update () {
     var forceX = 0f;
     var forceY = 0f;
     
     var absVelX = Mathf.Abs (rigidbody2D.velocity.x);
     var absVelY = Mathf.Abs (rigidbody2D.velocity.y);
     
     if (absVelY < .2f) {
         standing = true;
     } else {
         standing = false;
     }
     
     if (controller.moving.x != 0) {
         if (absVelX < maxVelocity.x) {
             
             forceX = standing ? speed * controller.moving.x : (speed * controller.moving.x * airSpeedMultiplier);
             
             transform.localScale = new Vector3 (forceX > 0 ? 1 : -1, 1, 1);
         }
         animator.SetInteger ("AnimState", 1);
     } else {
         animator.SetInteger ("AnimState", 0);
     }
     
     if (controller.moving.y > 0) {
         PlayRocketSound();
         if (absVelY < maxVelocity.y)
             forceY = jetSpeed * controller.moving.y;
         
         animator.SetInteger ("AnimState", 2);
     } else if (absVelY > 0) {
         animator.SetInteger("AnimState", 3);
     }
     
     rigidbody2D.AddForce (new Vector2 (forceX, forceY));
 }

}

WHAT CAN I DO?
