Question character moves backwards while pressing left/right

Hey, so I tried to make a movement script where the camera direction should be the players forward direction. That works very well, but when I walk sideways by pressing A or D the character is turning to the right side and walks backwards.
I would like that the player is walking left from camera direction when A is pressed and right when D is pressed, but dont really know what to change...

I used the new inputsystem with a Cinemachine FreeLook cam and just attached a CharacterController component on the gameobject itself. I'm using this code:

Code (CSharp):

1. using System;
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using UnityEngine.InputSystem;
6. using Cinemachine;
7.  
8. [RequireComponent(typeof(CharacterController))]
9. public class BasicMovementFinal : MonoBehaviour
10. {
11.     [SerializeField] private float moveSpeed = 10f;
12.     [SerializeField] private float jumpSpeed = 0.5f;
13.     [SerializeField] private float gravity = 2f;
14.     [SerializeField] private float rotationSpeed = 4f;
15.     private bool isJumped = false;
16.  
17.     [SerializeField] private InputActionReference movementControl;
18.     [SerializeField] private InputActionReference jumpControl;
19.     [SerializeField] private CinemachineFreeLook freeLookCam;
20.  
21.     private CharacterController characterController;
22.     private Transform cameraTransform;
23.  
24.     private void Awake()
25.     {
26.         characterController = gameObject.GetComponent<CharacterController>();
27.         cameraTransform = Camera.main.transform;
28.     }
29.  
30.     private void OnEnable()
31.     {
32.         movementControl.action.Enable();
33.  
34.         jumpControl.action.performed += HandleJump;
35.         jumpControl.action.Enable();
36.     }
37.  
38.     private void OnDisable()
39.     {
40.         movementControl.action.Disable();
41.  
42.         jumpControl.action.performed -= HandleJump;
43.         jumpControl.action.Disable();
44.     }
45.  
46.     private void HandleJump(InputAction.CallbackContext obj)
47.     {
48.         var value = obj.ReadValue<float>();
49.         isJumped = value >= .5f;
50.     }
51.  
52.     private Vector3 moveDirection;
53.  
54.     private void FixedUpdate()
55.     {
56.         #region Move
57.         Vector2 input = movementControl.action.ReadValue<Vector2>();
58.         Vector3 inputDirection = new Vector3(input.x, 0, input.y);
59.         Vector3 transformDirection;
60.  
61.         //Wenn S gedrückt wird läuft der Character in die entgegengesetzte Richtung in die die Cam zeigt
62.         if (inputDirection.z < 0)
63.         {
64.             Vector3 inverseDirection = new Vector3(inputDirection.x, inputDirection.y, inputDirection.z * -1f);
65.             transformDirection = transform.TransformDirection(inverseDirection);
66.         }
67.         else
68.             transformDirection = transform.TransformDirection(inputDirection);
69.  
70.         Vector3 flatMovement = moveSpeed * Time.deltaTime * transformDirection;
71.         moveDirection = new Vector3(flatMovement.x, moveDirection.y, flatMovement.z);
72.  
73.         //Jump
74.         if (isJumped && characterController.isGrounded)
75.             moveDirection.y = jumpSpeed;
76.         else if (characterController.isGrounded)
77.             moveDirection.y = 0f;
78.         else
79.             moveDirection.y -= gravity * Time.deltaTime;
80.  
81.         //Bewege
82.         characterController.Move(moveDirection);
83.  
84.         #endregion
85.         #region Rotation
86.         if (input != Vector2.zero)
87.         {
88.             float targetAngle = Mathf.Atan2(input.x, input.y) * Mathf.Rad2Deg + cameraTransform.eulerAngles.y;
89.             Quaternion rotation = Quaternion.Euler(0f, targetAngle, 0f);
90.             transform.rotation = Quaternion.Lerp(transform.rotation, rotation, Time.deltaTime * rotationSpeed);
91.         }
92.         #endregion
93.     }

i have the same problem in 2022
