我在努力改进角色的鼠标移动。在第一人称场景中，水平移动看起来很完美，但有时会随机地向上看/向下看的机制失控并自行运作。我用于水平和垂直的函数是相同的，但我不确定是什么原因会导致这种情况。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class MouseMovement : MonoBehaviour
{

    public float mouseSensitivity = 200f;

    float xRotation = 0f;
    float YRotation = 0f;

    void Start()
    {
        //Locking the cursor to the middle of the screen and making it invisible
        Cursor.lockState = CursorLockMode.Locked;
    }

    void Update()
    {
        if (!InventorySystem.Instance.isOpen ) //remove these) && !CraftingSystem.Instance.isOpen)
        {
            float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity * Time.deltaTime;
            float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity * Time.deltaTime;

            //control rotation around x axis (Look up and down)
            xRotation -= mouseY;

            //clamp the rotation so we dont Over-rotate (like in real life)
            xRotation = Mathf.Clamp(xRotation, -90f, 90f);

            //control rotation around y axis (Look up and down)
            YRotation += mouseX;

            //applying both rotations
            transform.localRotation = Quaternion.Euler(xRotation, YRotation, 0f);

        }
    }
}

解决方案

没错，似乎移除

Time.deltaTime

才是问题所在。下面的代码效果要好得多，但在较低的

public float mouseSensitivity = 3f;

请在这里查看最终的鼠标代码变更：

float mouseX = Input.GetAxis("Mouse X") * mouseSensitivity;
float mouseY = Input.GetAxis("Mouse Y") * mouseSensitivity;

再次感谢你的帮助！
