从零开始自学Unity

网上浅尝了一下Unity
对C#一无所知。教程里的脚本记录一下。

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

public class cameralook : MonoBehaviour
{
    private float xmove;
    public float mousespeed;
    public Transform player;
    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        //锁定鼠标位置 
    }
    // Update is called once per frame
    void Update()
    {
        float x, y;
        x = Input.GetAxis("Mouse X")*mousespeed*Time.deltaTime;
        //getaxis:axis是轴。即Input输入mousex的值。
        //getAxis("horizontal")对应键盘上面的左右箭头，当按下左或右箭头时触发
        y = Input.GetAxis("Mouse Y")*mousespeed*Time.deltaTime;
      //在unity世界里，y是数学里的z轴，垂直方向上面的变化。
      即：x的数值=mousex的值*mouse速度（自定义的）*时间
      
        player.Rotate(Vector3.up * x); 
        横向旋转。vector3.up是一个已经定义的结构体
        xmove = xmove - y;
        xmove = Mathf.Clamp(xmove, -90, 90);
        this.transform.localRotation = Quaternion.Euler(xmove, 0, 0);

        //this是脚本所挂载的物体 即是这个相机
       
    }
