How to Move rigidbody2D on touch ?

In my 2d Platformer (Unity 4.3) I had 3 scripts for left & right movement. One was Player.cs (Player Raycasting, Left and right movement, etc), MoveLeft.cs and Move Right.cs.

With Player.cs I had a setup Like this (Attached to Player)

 using UnityEngine;
 using System.Collections;
 
 public class Player : MonoBehaviour {
 
     public float PlayerMoveSpeed = 3f;
     public static bool PlayerMoveRight = false;
     public static bool PlayerMoveLeft = false;
     // Use this for initialization
     void Update()
     {
         //Run these to functions
         Movement();
     }
 
 void Movement()
     {
         //Touch Controls
 
         if(MoveRight == true)
         {
             transform.Translate(Vector2.right * PlayerMoveSpeed * Time.deltaTime);
             transform.eulerAngles = new Vector2(0, 0);
         }
             //Left Movement triggered
         if(MoveLeft == true)
         {
             transform.Translate(Vector2.right * PlayerMoveSpeed * Time.deltaTime);
             transform.eulerAngles = new Vector2(0, 180);  
         }
         }
    }

The variables MoveLeft & MoveRight would be set to true/false with these scripts..

MoveLeft.cs... For Left movement on touch (Attach to guiTexture Called MoveLeft)

 using UnityEngine;
 using System.Collections;
 
 public class MoveLeft : MonoBehaviour {
     
     // Update is called once per frame
     void Update () 
     {
         //Is there a touch?
         if(Input.touches.Length <= 0)
         {
             //If no touches...
         }
         else //If screen touched..
         {
             //Loop through these
             for(int i = 0; i < Input.touchCount; i++)
             { 
                 //executes this code for current touch
                 if(this.guiTexture.HitTest(Input.GetTouch(i).position))
                 {
                     //If current touch hits the guitexture...
 
 //MoveRight bool within PlayerLogic = false when touch has Began                if(Input.GetTouch(i).phase == TouchPhase.Began)
                     {  
                         Player.PlayerMoveLeft = true;
                     }
 //MoveLeft bool within PlayerLogic = false when touch has ended                    if(Input.GetTouch(i).phase == TouchPhase.Ended)
                     {
                     Player.PlayerMoveLeft = false;
                     }
                 }
             }
         }
     }
 }

MoveRight.cs... For Left movement on touch (Attach to guiTexture Called MoveRight)

 using UnityEngine;
 using System.Collections;
 
 public class MoveRight : MonoBehaviour {
 
     // Update is called once per frame
     void Update () 
     {
         //Is there a touch?
         if(Input.touches.Length <= 0)
         {
             //If no touches...
         }
         else //If screen touched..
         {
             //Loop through these
             for(int i = 0; i < Input.touchCount; i++)
             { 
                 //executes this code for current touch
                 if(this.guiTexture.HitTest(Input.GetTouch(i).position))
                 {
                     //If current touch hits the guitexture...
                     if(Input.GetTouch(i).phase ==  TouchPhase.Began)
                     { 
                         Player.PlayerMoveRight = true;
                     }
                     if(Input.GetTouch(i).phase == TouchPhase.Ended)
                     {
                         Player.PlayerMoveRight = false;
                     }
                 }
             }
         }
     }
 }

Change script names if needed and If you're using Javascript Google c# to javascript online and click on the first result.
