How to Unity create your own button to control the player on mobile device - unity3d

Question

i am not sure how to do this ,my goal is to create a button that will control the player on the plane for the mobile touch devices.I created the button I am trying to make it to control the player but i am failing here is my player c# script
using UnityEngine;
using System.Collections;
public class PlayerMovement : MonoBehaviour
{
public float speed = 500f, jumpHeight = 500f;
Transform myTrans;
Rigidbody2D myBody;
Vector2 movement;//used as temp holder variable before applying to velocity
bool isGrounded = true;
void Start ()
{
myTrans = this.transform;
myBody = this.GetComponent<Rigidbody2D>() ;
}
void Update ()
{
//Check if the player is grounded or not
isGrounded = Physics2D.Linecast(myTrans.position,
GameObject.Find(this.name+"/tag_ground").transform.position,
LayerMask.NameToLayer("Player"));
//Just for visualization, not needed for gameplay
Debug.DrawLine (myTrans.position,
GameObject.Find(this.name+"/tag_ground").transform.position,
Color.red);
//Works for keyboards and joysticks
#if !UNITY_ANDROID && !UNITY_IPHONE && !UNITY_BLACKBERRY && !UNITY_WINRT
Move (Input.GetAxisRaw("Horizontal"));
if (Input.GetButtonDown ("Jump"))
Jump ();
#endif
}
//
//Separate Move and Jump so they can be called externally by TouchButtons
//
public void Move(float horizontal_input)
{
movement = myBody.velocity;
if(isGrounded)//we can only move left and right if on the ground
movement.x = horizontal_input * speed * Time.deltaTime;
//Apply the movement to the player
myBody.velocity = movement;
}
public void Jump()//we can only jump if on the ground
{
if(isGrounded)
myBody.velocity += jumpHeight * Vector2.up * Time.deltaTime;
}
}
here is the touch logic script
using UnityEngine;
using System.Collections;
public class TouchLogicV2 : MonoBehaviour
{
public static int currTouch = 0;//so other scripts can know what touch is currently on screen
[HideInInspector]
public int touch2Watch = 64;
private new GUITexture guiTexture;
public virtual void Update()//If your child class uses Update, you must call base.Update(); to get this functionality
{
//is there a touch on screen?
if(Input.touches.Length <= 0)
{
OnNoTouches();
}
else //if there is a touch
{
//loop through all the the touches on screen
for(int i = 0; i < Input.touchCount; i++)
{
currTouch = i;
//executes this code for current touch (i) on screen
if(this.guiTexture != null && (this.guiTexture.HitTest(Input.GetTouch(i).position)))
{
//if current touch hits our guitexture, run this code
if(Input.GetTouch(i).phase == TouchPhase.Began)
{
OnTouchBegan();
touch2Watch = currTouch;
}
if(Input.GetTouch(i).phase == TouchPhase.Ended)
{
OnTouchEnded();
}
if(Input.GetTouch(i).phase == TouchPhase.Moved)
{
OnTouchMoved();
}
if(Input.GetTouch(i).phase == TouchPhase.Stationary)
{
OnTouchStayed();
}
}
//outside so it doesn't require the touch to be over the guitexture
switch(Input.GetTouch(i).phase)
{
case TouchPhase.Began:
OnTouchBeganAnywhere();
break;
case TouchPhase.Ended:
OnTouchEndedAnywhere();
break;
case TouchPhase.Moved:
OnTouchMovedAnywhere();
break;
case TouchPhase.Stationary:
OnTouchStayedAnywhere();
break;
}
}
}
}
//the default functions, define what will happen if the child doesn't override these functions
public virtual void OnNoTouches(){}
public virtual void OnTouchBegan(){print (name + " is not using OnTouchBegan");}
public virtual void OnTouchEnded(){}
public virtual void OnTouchMoved(){}
public virtual void OnTouchStayed(){}
public virtual void OnTouchBeganAnywhere(){}
public virtual void OnTouchEndedAnywhere(){}
public virtual void OnTouchMovedAnywhere(){}
public virtual void OnTouchStayedAnywhere(){}
}
I am following the touchlogic tuts but am struggling to move the player on mobile.Any with good examples on touch input is welcomed to give me the links for examples.thanks
