Y轴相机移动[重复]答案

【问题标题】：Y axis camera movement [duplicate]Y轴相机移动[重复]

【问题描述】：

我一直在为 3D FPS 制作运动，除了相机运动外，一切都很好。

我将其设置为根据光标在 X 轴上旋转刚体，并根据光标在 Y 轴上旋转相机。

问题在于 Y 轴没有限制，您可以向后看，甚至可以进行多次 360 转。我没有使用 Clamp 的经验。

我的两个脚本控制播放器。

using UnityEngine;

[RequireComponent(typeof(PlayerMotor))]
public class PlayerControler : MonoBehaviour {

    private float speed = 5f;

    float lookSensitivity = 70f;

    private PlayerMotor motor;

    void Start ()
    {
        motor = GetComponent<PlayerMotor>();
    }

    void Update ()
    {
        float _xMov = Input.GetAxis("Horizontal");
        float _zMov = Input.GetAxis("Vertical");

        Vector3 _movHorizontal = transform.right * _xMov;
        Vector3 _movVertical = transform.forward * _zMov;

        Vector3 _velocity = (_movHorizontal + _movVertical).normalized * speed;

        motor.Move(_velocity);

        //Turning

        float _yRot = Input.GetAxis("Mouse X");

        Vector3 _rotation = new Vector3 (0f, _yRot, 0f) * lookSensitivity;

        motor.Rotate(_rotation);

        //Camera Rotation

        float _xRot = Input.GetAxis("Mouse Y");

        Vector3 _cameraRotation = new Vector3 (_xRot, 0f, 0f) * lookSensitivity;

        motor.RotateCamera(-_cameraRotation);
    }
}

using UnityEngine;

[RequireComponent(typeof(Rigidbody))]

public class PlayerMotor : MonoBehaviour {

    [SerializeField]
    private Camera cam;

    private Vector3 velocity = Vector3.zero;
    private Vector3 rotation = Vector3.zero;
    private Vector3 cameraRotation = Vector3.zero;

    private Rigidbody rb;

    void Start ()
    {
        rb = GetComponent<Rigidbody>();
    }

    public void Move (Vector3 _velocity)
    {
        velocity = _velocity;
    }

    public void Rotate (Vector3 _rotation)
    {
        rotation = _rotation;
    }

    public void RotateCamera (Vector3 _cameraRotation)
    {
        cameraRotation = _cameraRotation;
    }

    void FixedUpdate ()
    {
        PerformMovement();
        PreformRotation();

    }

    void PerformMovement ()
    {
        if (velocity != Vector3.zero)
        {
            rb.MovePosition(rb.position + velocity * Time.fixedDeltaTime);
        }
    }

    void PreformRotation ()
    {
        rb.MoveRotation(rb.rotation * Quaternion.Euler (rotation));

        if (cam != null)
        { 
            cam.transform.Rotate(cameraRotation);
            Cursor.lockState = CursorLockMode.Locked;
            Cursor.visible = false;

        }
            /*cameraRotation = Mathf.Clamp(cameraRotation.x, -89f, 89f);
            Cursor.lockState = CursorLockMode.Locked;
            Cursor.visible = false;
        localRotation = Quaternion.Euler(cameraRotation, rotation, 0);*/
    }
}

请提出建议。

到底是什么问题？

【解决方案1】：

我假设您想将 x 旋转限制在最大值和最小值之间，这就是夹紧的意思。

这一行之后

float _xRot = Input.GetAxis("Mouse Y");

首先确保角度在 0 到 360 度之间：

if (_xRot < -360F) _xRot += 360F;
if (_xRot > 360F) _xRot -= 360F;

然后将其限制在最大值和最小值之间：

float min = -70f;
float max = 70f;
_xRot = Mathf.Clamp(_xRot, min, max);
