Question

在我的游戏中，我有一个相机，我希望在相机上安装一个像旋转一样的FPS。

因此，如果我将光标移到左侧，我希望我的相机向左旋转。如果我向上移动光标，那么凸轮应该向上看，等等。

我目前正在部分工作。我可以向左，向右，向上和向下看。当我向下看，然后左右移动光标时，会出现问题。然后它给我一个“滚动”效果。

观看此视频，了解我的意思： http://www.screencast.com/t/Phedh8H0K13

显然，当我向下看时，我仍然希望产生“偏航”效果，而不是“滚动”效果。任何人都知道如何做到这一点？这就是我到目前为止所做的：

// Update is called once per frame
public override void update ()
{
    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityRoll * Input.GetAxis("Vertical"), Vector3.forward );

    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityYaw * Input.GetAxis("Mouse X"), Vector3.up );

    this.camera.transform.rotation *= 
        Quaternion.AngleAxis( Time.deltaTime * sensitivityPitch * Input.GetAxis("Mouse Y"), Vector3.left );
}

我刚才在这个主题中找到了答案：

http://forum.unity3d.com/threads/109250-Looking-with-the-Mouse?highlight=person+camera

该主题的代码：

C＃Mono代码：

using UnityEngine;
using System.Collections;

/// MouseLook rotates the transform based on the mouse delta.
/// Minimum and Maximum values can be used to constrain the possible rotation

/// To make an FPS style character:
/// - Create a capsule.
/// - Add the MouseLook script to the capsule.
///   -> Set the mouse look to use LookX. (You want to only turn character but not tilt it)
/// - Add FPSInputController script to the capsule
///   -> A CharacterMotor and a CharacterController component will be automatically added.

/// - Create a camera. Make the camera a child of the capsule. Reset it's transform.
/// - Add a MouseLook script to the camera.
///   -> Set the mouse look to use LookY. (You want the camera to tilt up and down like a head. The character already turns.)
[AddComponentMenu("Camera-Control/Mouse Look")]
public class MouseLook : MonoBehaviour {

    public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
    public RotationAxes axes = RotationAxes.MouseXAndY;
    public float sensitivityX = 15F;
    public float sensitivityY = 15F;

    public float minimumX = -360F;
    public float maximumX = 360F;

    public float minimumY = -60F;
    public float maximumY = 60F;

    float rotationY = 0F;

    void Update ()
    {
        if (axes == RotationAxes.MouseXAndY)
        {
            float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX;

            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
        }
        else if (axes == RotationAxes.MouseX)
        {
            transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0);
        }
        else
        {
            rotationY += Input.GetAxis("Mouse Y") * sensitivityY;
            rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);

            transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
        }
    }

    void Start ()
    {
    //if(!networkView.isMine)
        //enabled = false;

        // Make the rigid body not change rotation
        //if (rigidbody)
            //rigidbody.freezeRotation = true;
    }
}

我为我的FPS项目创建了2个脚本，这些脚本可以完美地适应我的运动（目前已经添加了跳跃机制），而且似乎使很多事情变得过于复杂了，这些事情可能非常简单直接。我对代码也很陌生，所以如果我做错了，请纠正我的代码

//这是在播放器脚本中，我把它放在相机和播放器精灵的空父对象上

public class player : MonoBehaviour
{
    [Header("player Movement")]
    [SerializeField] float moveSpeed = 5f;
    [SerializeField] public float mouseSensitivity = 5f;


    Rigidbody rigidBody;

    // Use this for initialization
    void Start()
    {

    }

 void Update()
    {
        Move();

    }


    private void Move()
    {
        transform.Translate(Vector3.forward * Input.GetAxis("Vertical") * moveSpeed * Time.deltaTime);
        transform.Translate(Vector3.right * Input.GetAxis("Horizontal") * moveSpeed * Time.deltaTime);
        transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime);
    }

//这是我放在相机上的相机移动脚本（还将使用此脚本添加一项功能，以将某些功能从第一人称更改为第三人称）

{

    player player;
    // Use this for initialization
    void Start()
    {
        player = FindObjectOfType<player>();
    }

    // Update is called once per frame
    void Update()
    {
        MoveView();
    }
    private void MoveView()
    {
        transform.Rotate(Vector3.left * Input.GetAxis("Mouse Y") * player.mouseSensitivity * Time.deltaTime);
    }
}

简单的脚本（不确定它是否可以与您一起使用），不妨尝试一下

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Security.Cryptography;
using System.Threading;
using UnityEngine;

public class mouse_lookat : MonoBehaviour
{
    public float mouseSensitivity = 100f;

    public Transform playerBody;

    float xRotation = 0f;

    // Start is called before the first frame update
    void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
    }

    // Update is called once per frame
    void Update()
    {
        float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
        float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.localRotation = Quaternion.Euler(xRotation, 0f, 0f);
        playerBody.Rotate(Vector3.up * mouseX);
    }
}
