摄像头抖动已经在非常简单的脚本中出现了

你好！

我正在尝试解决摄像头抖动的问题。在游戏模式下，无法解决这个问题。

我创建了一个新项目，包含两个简单的脚本：一个用于角色移动，一个用于摄像头控制（围绕角色旋转）。

输入通过新输入系统处理，WASD用于正交移动，鼠标用于摄像头控制。

以下是玩家控制器脚本：

using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerMovement : MonoBehaviour
{
    private PlayerInputAction inputActions;
    private Vector2 moveInput;

    public Transform cameraTransform;
    public float speed = 2.5f;

    private void Awake()
    {
        inputActions = new PlayerInputAction();
    }

    private void OnEnable()
    {
        inputActions.Player.Enable();

        inputActions.Player.Move.performed += ctx => moveInput = ctx.ReadValue<Vector2>();
        inputActions.Player.Move.canceled += ctx => moveInput = Vector2.zero;
    }

    private void OnDisable()
    {
        inputActions.Player.Disable();
    }

    void Update()
    {
        // direction caméra (flat sur le sol)
        Vector3 camForward = cameraTransform.forward;
        Vector3 camRight = cameraTransform.right;

        camForward.y = 0;
        camRight.y = 0;

        camForward.Normalize();
        camRight.Normalize();

        // direction de déplacement relative caméra
        Vector3 moveDir = camForward * moveInput.y + camRight * moveInput.x;

        transform.position += moveDir * speed * Time.deltaTime;

        // optionnel : rotation du player vers direction de mouvement
        if (moveDir != Vector3.zero)
        {
            transform.forward = moveDir;
        }
    }
}

以下是摄像头控制脚本：

using UnityEngine;
using UnityEngine.InputSystem;

public class CameraOrbit : MonoBehaviour
{
    [Header("Target")]
    public Transform target;

    [Header("Settings")]
    public float sensitivity = 0.5f;
    public float distance = 8f;
    public float minY = 30f;
    public float maxY = 30f;

    private PlayerInputAction input;

    private float yaw;
    private float pitch;

    private Vector2 lookInput;

    private void Awake()
    {
        input = new PlayerInputAction();
    }

    private void OnEnable()
    {
        input.Player.Enable();

        input.Player.Look.performed += ctx => lookInput = ctx.ReadValue<Vector2>();
        input.Player.Look.canceled += ctx => lookInput = Vector2.zero;
    }

    private void OnDisable()
    {
        input.Player.Disable();
    }

    void LateUpdate()
    {
        if (!target) return;

        yaw += lookInput.x * sensitivity;
        pitch -= lookInput.y * sensitivity;
        pitch = Mathf.Clamp(pitch, minY, maxY);

        Quaternion rotation = Quaternion.Euler(pitch, yaw, 0);

        Vector3 offset = rotation * new Vector3(0, 0, -distance);

        transform.position = target.position + offset;
        transform.LookAt(target.position);
    }
}

摄像头运动抖动已经存在，出现跳跃等问题，甚至在一个空白的新项目中也存在这些问题。
