How to remove the Vertical axis on Joystick?

Hello! I’m new on this so I don’t realy know how to remove the Vertical movement of my joystick, so I will realy apreciate if someone can help me! here is the code and a picture with my Joystick.In this moment my Joystick can be moved in circle, even if the image shows that is only for right and left movement, and i dont know how to "block"or “stop” the movement in circle and up and down.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.EventSystems;

public class JoyStick : MonoBehaviour, IPointerDownHandler, IPointerUpHandler, IDragHandler
{
public RectTransform pad;
public Transform player;
Vector3 moveForward;
Vector3 moveRotate;
public float moveSpeed;
public float rotateSpeed;

public void OnPointerDown(PointerEventData eventData)
{
    StartCoroutine("PlayerMove");
}

public void OnPointerUp(PointerEventData eventData)
{
    transform.localPosition = Vector3.zero;
    moveForward = Vector3.zero;
    moveRotate = Vector3.zero;
    StopCoroutine("PlayerMove");
}

public void OnDrag(PointerEventData eventData)
{
    transform.position = eventData.position;
    transform.localPosition = Vector2.ClampMagnitude(eventData.position - (Vector2)pad.position, pad.rect.width * 0.3f);

    //moveForward = new Vector3(0, 0, transform.localPosition.y).normalized;
    moveRotate = new Vector3(0, transform.localPosition.x, 0).normalized;
}

IEnumerator PlayerMove()
{
    while (true)
    {
        player.Translate(moveForward * moveSpeed * Time.deltaTime);

        if (Mathf.Abs(transform.localPosition.x) > pad.rect.width * 0.2f)
            player.Rotate(moveRotate * rotateSpeed * Time.deltaTime);

        yield return null;
    }
}

}

The problem is at line 17 where you calculate the local position for x and y (y should be constant and 0 most likely) so the code should look like this:

     public void OnPointerDown(PointerEventData eventData)
     {
         StartCoroutine("PlayerMove");
     }
     public void OnPointerUp(PointerEventData eventData)
     {
         transform.localPosition = Vector3.zero;
         moveForward = Vector3.zero;
         moveRotate = Vector3.zero;
         StopCoroutine("PlayerMove");
     }
     public void OnDrag(PointerEventData eventData)
     {
         transform.position = eventData.position;
		 var maxXValue = pad.rect.width * 0.3f; 
		 var xPosition = Mathf.Clamp(eventData.position.x - pad.position.x, -maxXValue, maxXValue)
         transform.localPosition = new Vector2(xPosition, 0f);
         //moveForward = new Vector3(0, 0, transform.localPosition.y).normalized;
         moveRotate = new Vector3(0, transform.localPosition.x, 0).normalized;
     }
     IEnumerator PlayerMove()
     {
         while (true)
         {
             player.Translate(moveForward * moveSpeed * Time.deltaTime);
             if (Mathf.Abs(transform.localPosition.x) > pad.rect.width * 0.2f)
                 player.Rotate(moveRotate * rotateSpeed * Time.deltaTime);
             yield return null;
         }
     }

As you can see, I only calculated the x local position and for y I just pass the value 0f. Hope this helps
