How to make A Joystick Movement Controller that moves the character based on the camera Angle (ARCore)

Hi!

I am working in a ARCore Game project. In a scene, Where user will spawn the Playable Character, I want the user to be able to move the character using a joystick. But the catch is, since I am making it with Augmented reality, that means User will move around the area with their phone.

So, I want the joy stick to work such that, if the User Pushes "Vertical Up" the character should always walk Away from the camera. In other worlds I want the joystick to take the Phones's camera Origin and Orientation as its parent rather than taking the Game-Scene's Origin as Parent when it comes to defining X, Y and Z Axis.

Also I have added a second Joystick that user can use to rotate the Character around the Character's axis to shoot enemies at 360 degrees around it.

I found "THIS" tutorial that I Implemented. When I tested it, the object is moving and rotating just fine, But it is not moving the way I mentioned above. It seems to go forward in the same direction regardless of where I position the camera.

Here's the Scripts I have written (Movement_Controller.cs):

 using System;
 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Movement_Controller : MonoBehaviour
 {
     public FixedJoystick moveJoystick;
     GameObject objMove_Joystick;
 
     public FixedJoystick LookJoystick;
     GameObject objLook_Joystick;
 
 
     private static float hoz;
     private static float ver;
 
     Vector3 direction;
     void Update()
     {
         if (NewTap2Place.objectinScene == true)
         {
             MoveJoystick();
             look_JoyStick();
         }
     }
 
     void MoveJoystick()
     {
         objMove_Joystick = GameObject.FindGameObjectWithTag("Movement_Stick") as GameObject;
         moveJoystick = objMove_Joystick.GetComponent<FixedJoystick>();
 
         hoz = moveJoystick.Horizontal;
         ver = moveJoystick.Vertical;
 
         Vector3 convertedXY = ConvertWithCamera(Camera.current.transform.position, hoz, ver);
 
         direction = new Vector3(convertedXY.x, 0, convertedXY.y);
 
       
         //Debug.Log(direction);
     }
 
     void look_JoyStick()
     {
         objLook_Joystick = GameObject.FindGameObjectWithTag("Look_Stick") as GameObject;
         LookJoystick = objLook_Joystick.GetComponent<FixedJoystick>();
 
         hoz = LookJoystick.Horizontal;
         ver = LookJoystick.Vertical;
 
         Vector3 convertedXY = ConvertWithCamera(Camera.current.transform.position, hoz, ver);
 
         direction = new Vector3(convertedXY.x, 0, convertedXY.y);
 
         Vector3 LookatPosition = transform.position + direction;
         transform.LookAt(LookatPosition);
         //Debug.Log(direction);
     }
     private Vector2 ConvertWithCamera(Vector3 cameraPos, float hor, float ver)
     {
         Vector2 joyDirection = new Vector2(hor, ver).normalized;
         Vector2 camera2Pos = new Vector2(cameraPos.x, cameraPos.y);
         Vector2 cameraToPlayerDirection = (Vector2.zero - camera2Pos).normalized;
         float angle = Vector2.SignedAngle(cameraToPlayerDirection, new Vector2(0, 1));
         Vector2 finalDirection = RotateVector(joyDirection, -angle);
         return finalDirection;
     }
 
     private Vector2 RotateVector(Vector2 v, float angle)
     {
         float radian = angle * Mathf.Deg2Rad;
         float _x = v.x * Mathf.Cos(radian) - v.y * Mathf.Sin(radian);
         float _y = v.x * Mathf.Sin(radian) + v.y * Mathf.Cos(radian);
 
         return new Vector2(_x, _y);
     }
 }
 

I am using Unity: 2019.4, ARFoundation: 4.1.0 I have also tagged the ARCamera as Main Camera in its inspector.

Also I am instantiating the object after the user taps on the screen, does that affect the coordinate system?

Thanks in advance!
