🎶PlayerPrefs基本内容

• API大全图解
  

🎶PalyerPrefs存储知识

• windows平台存储路径
  
  HKCU\Software[公司名称][产品名称] 项下的注册表中
  公司和产品名称是 在“Project Settings”中设置的名称。
  1.运行 regedit (win+R)
  2/HKEY_CURRENT_USER
  3/SOFTWARE
  4.Unity
  5.UnityEditor
  6.公司名称
  7.产品名称
  
• Android平台存储路径
  
  /data/data/包名/shared_prefs/pkg-name.xml
  
• IOS平台存储路径
  
  /Library/Preferences/[应用ID].plist

🎶PalyerPrefs知识小结

• 用palyerfabs存储多对象数据时的代码模块

1.list列表 List
2.存储方法 Save()
3.读取方法 Read()

🎶PalyerPrefs代码实践

>题目：现在有玩家信息类，有名字，年龄，攻击力，防御力等成员现在为其封装两个方法，—个用来存储数据，一个用来读取数据现在在装备信息类，装备类中有id，数量两个成员。

using System.Collections.Generic;
using UnityEngine;


class PalyerMess
{
   private  string name;
   private int age;
   private int atack;
   private int defend;

    /// 存储数据
    /// </summary>
    public void Save()
    {
        PlayerPrefs.SetString("name","孙悟空");
        PlayerPrefs.SetInt("age", 108);
        PlayerPrefs.SetInt("atack", 999);
        PlayerPrefs.SetInt("defend", 1000);
