Question

我从Youtube Unity教程视频中复制了这段代码，但我无法弄清楚它有什么问题。

当我团结一致地玩游戏时，我试着用鼠标向上看，它试图阻止我这样做。

using UnityEngine;
using System.Collections;

public class FirstPersonController : MonoBehaviour {

    public float movementSpeed = 5.0f;
    float verticalRotation = 0; 
    public float upDownRange = 60.0f;

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {

        //Rotation
        float rotLeftRight = Input.GetAxis("Mouse X");
        transform.Rotate(0, rotLeftRight, 0);

        verticalRotation = Input.GetAxis("Mouse Y");
        verticalRotation = Mathf.Clamp(verticalRotation, -upDownRange, upDownRange);
        Camera.main.transform.localRotation = Quaternion.Euler(verticalRotation, 0, 0);

        //Movement
        float forwardSpeed = Input.GetAxis ("Vertical") * movementSpeed;
        float sideSpeed = Input.GetAxis("Horizontal") * movementSpeed;

        Vector3 speed = new Vector3 (sideSpeed, 0, forwardSpeed);

        speed = transform.rotation * speed;

        CharacterController cc = GetComponent<CharacterController>();

        cc.SimpleMove (speed);
    }
}

Answer 1

我认为问题在于您在verticalRotation中指定Mouse Y值而不是递增它。

尝试类似：

float yAxis = Input.GetAxis("Mouse Y");
verticalRotation = Mathf.Clamp(verticalRotation + yAxis, -upDownRange, upDownRange);`

也许你应该有一个rotationSpeed，就像你有movingSpeed一样。

如果此脚本在相机上，则：

在这里，尝试用更简单的方式替换您的更新。

void Update()
{

    //Rotation

    float rotLeftRight = Input.GetAxis("Mouse X");
    //transform.Rotate(0, rotLeftRight, 0);

    verticalRotation = Input.GetAxis("Mouse Y");
    verticalRotation = Mathf.Clamp(verticalRotation, -upDownRange, upDownRange);
    //Only add the rotation when both values are set so you don't overwrite the first one.
    transform.Rotate(-verticalRotation, rotLeftRight, 0);

    //Movement
    float forwardSpeed = Input.GetAxis("Vertical") * movementSpeed;
    float sideSpeed = Input.GetAxis("Horizontal") * movementSpeed;

    Vector3 speed = new Vector3(sideSpeed, 0, forwardSpeed);

    speed = transform.rotation * speed;

    CharacterController cc = GetComponent<CharacterController>();

    cc.SimpleMove(speed);
}

我相信你的主要问题是你在设置X时将Y设置为0然后稍微设置Y后将X设置为0，因为这是在更新中，它看起来很紧张并且结束了两者均为0。

Unity旋转不能在Y轴上工作
