【问题描述】：

我无法限制 Y 轴上的旋转，而且我会让我的玩家朝他移动的方向看，我已经尝试将 Mathf.calmp 放在Touchfiled.Touchdist.y（相机 Y 轴）但它不起作用我不知道问题出在哪里，但我想解决它，所以请帮助我。 这是我的代码：

    public FloatingJoystick joystick;
    public TouchField touchField;
    public GameObject FocusPoint;

    [HideInInspector] public CharacterController characterController;
    [HideInInspector] public Vector3 motionVector , gravityVector, RelativeVector;

    [Header("Player Settings")]
    [Range(0,6)] public float PlayerSpeed = 2.5f;
    [Range(0, 100)] public float Sensivility = 50;
    [Range(0, 0.5f)] public float groundClearance;

    private float gravityForce = -9.18f;
    private float gravityPower = -9.8f;
    private float JumpValue = 9.8f;
    private float TurnDiraction;

    private void Start()
    
        characterController = GetComponent<CharacterController>();
    

    private void Update()
    
        Movment();
        CameraController();

        if (characterController.isGrounded)
        
            print("Grounded");
        

    

    public void CameraController()
    
        RelativeVector = transform.InverseTransformPoint(FocusPoint.transform.position);
        RelativeVector /= RelativeVector.magnitude;
        TurnDiraction = (RelativeVector.x / RelativeVector.magnitude);
        FocusPoint.transform.eulerAngles = new Vector3(FocusPoint.transform.eulerAngles.x + touchField.TouchDist.y, FocusPoint.transform.eulerAngles.y, 0) ;
        FocusPoint.transform.parent.Rotate(transform.up * touchField.TouchDist.x * Sensivility * Time.deltaTime);

    

    public void Movment()
    
        if (characterController.isGrounded && gravityVector.y < 0)
        
            gravityVector.y = -2;
        

        gravityVector.y += gravityPower * Time.deltaTime;
        characterController.Move(gravityVector * Time.deltaTime);

        if (characterController.isGrounded)
        
            motionVector = transform.right * joystick.Horizontal + transform.forward * joystick.Vertical;
            characterController.Move(motionVector * PlayerSpeed * Time.deltaTime);

            if(joystick.Vertical > 0)
            
                transform.Rotate(transform.up * TurnDiraction * 800 * Time.deltaTime);
                FocusPoint.transform.parent.Rotate(transform.up * -TurnDiraction * 800 * Time.deltaTime);
            
        

    

【参考方案1】：

您分两步旋转，然后在第二步和第二步中旋转：

FocusPoint.transform.parent.Rotate(transform.up * touchField.TouchDist.x * Sensivility * Time.deltaTime);

如果您旋转父对象，则所有子对象都沿 y 轴旋转，同时旋转给层次结构中的父对象。 所以你在上一步中夹住y旋转并不重要

FocusPoint.transform.eulerAngles = new Vector3(FocusPoint.transform.eulerAngles.x + touchField.TouchDist.y, FocusPoint.transform.eulerAngles.y, 0);

如果游戏对象之后要相对于 y 轴旋转。

尝试根据您的限制一次轮换，或在所有轮换步骤中考虑这些限制。
