Why my playerMovement lagging?,Why my camera lagging when player moves

Questions & Answers

Hi I’m making a tiny game right now and I have a small issue with the smooth camera movement. When I start playing and move the player around the platform the camera follows the player but the player movement starts lagging and player movement is not smooth. Can someone help me with that? Thanks! Im putting a script of cameraController down below.

camera controller:

public Transform target;

public float smoothSpeed = 0.125f;
public Vector3 offSet;

private void FixedUpdate()
{
    Vector3 desiredPosition = target.position + offSet;
    Vector3 smoothedPosition = Vector3.Lerp(transform.position, desiredPosition, smoothSpeed);
    transform.position = smoothedPosition;

    transform.LookAt(target);
}

and player movement script:

public Transform playerTransform;

public CharacterController characterController;

public float speed = 6f;

private void Update()
{
    Move();

    if (Input.GetKey(KeyCode.Q))
    {
        playerTransform.transform.Rotate(0f, -1f, 0f);
    }

    if (Input.GetKey(KeyCode.E))
    {
        playerTransform.transform.Rotate(0f, 1f, 0f);
    }
}

void Move()
{
    float HorizontalMove = Input.GetAxis("Horizontal");
    float VerticalMove = Input.GetAxis("Vertical");

    Vector3 move = transform.forward * VerticalMove + transform.right * HorizontalMove;
    characterController.Move(speed * Time.deltaTime * move);

Hi, I’m new to unity too but I think I can give you tips that might help you. Well, using transform.Rotate(), Isn’t recommended in there, because it uses eulers, and they can get “glitchy” really easily, I recommend you to try using Quaternion, and used FixedUpdate on player movement instead of just Update, and about the camera, instead of FixedUpdate, use LateUpdate, maybe that could help. Hopefully, I helped you a little.
