How to remove the Vertical axis on Joystick?

Question

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
