Unity 相机在屏幕上滑动，第一人称 [英] Unity camera flicks across screen, first person

问题描述

您好，我是 UNITY 的新手，我为第一人称相机编写了一些代码，但是有时当我环顾四周时，它会轻弹相机面向的方向.这是我的代码

Hello I am new to UNITY I have written some code for a first person camera however sometimes when I am looking around it will flick what way the camera is facing. This is my code

public float mouseSensitivity = 200f;
public Transform playerBody;
float yRotation = 0f;

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

// 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;

    yRotation -= mouseY;
    yRotation = Mathf.Clamp(yRotation, -90f, 90f);
    transform.localRotation = Quaternion.Euler(yRotation, 0f, 0f);
    playerBody.Rotate(Vector3.up * mouseX);
}

我有一个视频来展示我的问题https://youtu.be/nMopJzNyYr4问题不清楚.

I have a video to show my issue as well https://youtu.be/nMopJzNyYr4 for is the question is not clear.

我有一个胶囊作为我的父母，它是玩家的实际身体，然后我的相机是 playerBody 的孩子(我的胶囊)

I have a capsule as my parent it is the players actual body and then my camera is a child to the playerBody ( my capsule )

推荐答案

尝试不用 deltaTime 乘法.鼠标轴上的 GetAxis 为您提供鼠标位置的差异，除非您对 deltaTime 或任何其他时间增量="https://en.wikipedia.org/wiki/Absement" rel="nofollow noreferrer">Absement 你可能不是！

Try it without the deltaTime multiplication. GetAxis on a mouse axis gives you a difference in mouse position, which should not be multiplied by deltaTime or any other time delta unless you are interested in a measurement of Absement which you probably are not!!

您对距离测量更感兴趣，因此您可以使用float mouseABC = Input.GetAxis("Mouse ABC") * mouseSensitivity;.

You are more interested in a distance measurement, so you can just use float mouseABC = Input.GetAxis("Mouse ABC") * mouseSensitivity;.

或者，如果您想要鼠标移动的速度，您实际上宁愿除以time.deltaTime，例如float mouseHorizo​​ntalVelocity = Input.GetAxis("Mouse X") * mouseSensitivity/Time.deltaTime;.

Alternatively, if you were to want the speed of the mouse movement, you would actually rather divide by time.deltaTime such as float mouseHorizontalVelocity = Input.GetAxis("Mouse X") * mouseSensitivity / Time.deltaTime;.
