How would I make it where the character moves where its facing based on camera?

Question

Im using Input Actions which I'm not too familiar with. How would I make it where the character moves where he is looking?

 PlayerInput playerInput;
 CharacterController characterController;
 Animator animator; 

 Vector2 currentMovementInput;
 Vector3 currentMovement;
 bool isMovementPressed;
 public float rotationFactoredPerFrame = 1f;
 public Transform camera;

 float turnSmoothVelocity;

 void Awake()
 {
     playerInput = new PlayerInput();
     characterController = GetComponent<CharacterController>();
     animator = GetComponent<Animator>();

     playerInput.CharacterControls.Move.started += OnInputMovement;
     playerInput.CharacterControls.Move.canceled += OnInputMovement;
     playerInput.CharacterControls.Move.performed += OnInputMovement;

 }

 void HandleRotation()
 {
    /* Vector3 postionToLookAt;

     postionToLookAt.x = currentMovement.x;
     postionToLookAt.y = 0;
     postionToLookAt.z = currentMovement.z;
     
     Quaternion currentRotation = transform.rotation;

     if(isMovementPressed)
     {
         Quaternion targerRotation = Quaternion.LookRotation(postionToLookAt);
         transform.rotation = Quaternion.Slerp(currentRotation, targerRotation, rotationFactoredPerFrame * Time.deltaTime);
     } */

     if(isMovementPressed)
     {
         float targetAngle = Mathf.Atan2(currentMovement.x, currentMovement.z) * Mathf.Rad2Deg + camera.eulerAngles.y;
         float angle = Mathf.SmoothDampAngle(transform.eulerAngles.y, targetAngle, ref turnSmoothVelocity, rotationFactoredPerFrame);
         transform.rotation = Quaternion.Euler(0f, targetAngle, 0f);
     }

 }

 void OnInputMovement(InputAction.CallbackContext context)
 {
     currentMovementInput = context.ReadValue<Vector2>();
     currentMovement.x = currentMovementInput.x;
     currentMovement.z = currentMovementInput.y;
     isMovementPressed = currentMovementInput.x != 0 || currentMovementInput.y != 0;
 }

 void HandleAnimation()
 {
     bool isWalking = animator.GetBool("isWalking");
     bool isRunning = animator.GetBool("isRunning");

     if(isMovementPressed && !isWalking)
     {
         animator.SetBool("isWalking", true);
     }
     else if(!isMovementPressed && isWalking)
     {
         animator.SetBool("isWalking", false);
     }
 }

 void Update()
 {
     HandleAnimation();
     HandleRotation();
     characterController.Move(currentMovement * Time.deltaTime);
 }

 void OnEnable()
 {
     playerInput.CharacterControls.Enable();
 }

 void OnDisable()
 {
     playerInput.CharacterControls.Disable();
 }

}

So I post my code where you can get both functions by removing the condition unless you want to I know i used rigidbody so i think you can use Slerp to rotate

 //the position where the camera look (so about the head)
 lookPos = new Vector3(transform.position.x, transform.position.y + lookHeight, transform.position.z);
 
             _xRotation += Mouse_X * sensX * Time.smoothDeltaTime;
             _yRotation += -Mouse_Y * sensY * Time.smoothDeltaTime;
 
             _yRotation = Mathf.Clamp(_yRotation, limitUp, limitDown);
 
             Vector3 Direction = new Vector3(0, 0, -distance);
             Quaternion rotation = Quaternion.Euler(_yRotation, _xRotation, 0);
             _mainCamera.transform.position = lookPos + rotation * Direction;
 
             _mainCamera.transform.LookAt(lookPos);
 
             //remove this condition if you want to rotate always not only when moved
             if (_inputManager.Move != Vector2.zero)
             {
                 _playerRigidbody.MoveRotation(Quaternion.Euler(0, _xRotation, 0));
             }

THIS

 Quaternion newRotation = Quaternion.Euler(0, _xRotation, 0));
    transform.rotation = Quaternion.Slerp(
                                transform.rotation, newRotation, rotationSpeed * Time.deltaTime);

I think the problem for me is that I dont know how to get AxisRaw from currentMovement.x and z

Create a Vector2 of your inputs of the inputsystem and normalize it

so

 Vector2 _inputDirection = new Vector2(_inputManager.Move.x, _inputManager.Move.y).normalized;

other I advice you to create another script with all the references of the InputSystem like this https://pastebin.com/R20XJkK7 if you need other stuff ask me ;)

remember to declare after in your code the references of the new script

  private InputManager _inputManager;  //in the variables
     
     _inputManager = GetComponent<InputManager>(); //in the Start/Awake

Ok thank you.

How would I make it where the character moves where its facing based on camera?
