1.基础存储

unity提供的现成可用的本地存储方式：

        PlayerPrefs.SetFloat("size", 1.5f);
        PlayerPrefs.SetInt("age", 10);
        PlayerPrefs.SetString("name", "David");

2.单个gameObjct数据存储

2.1实体类

 
using UnityEngine;
 
public class Entity_fwy
{
 
    public enum_fwy state;
    
    public string name_fwy = "";
    
    public int age;
 
}

2.2赋值存储

using System.Collections;
using System.Collections.Generic;
using Newtonsoft.Json;
using UnityEngine;
using static Pp_enum;
 
public class Contr_fwy : MonoBehaviour
{
    
    void Start()
    {
        
        Entity_fwy entityFwy = new Entity_fwy();
        entityFwy.state = enum_fwy.idle;
        entityFwy.name_fwy = "XiaoBai";
        entityFwy.age = 18;
 
        //存储
        PlayerPrefs.SetString("fwy", JsonConvert.SerializeObject(entityFwy));
 
        //获取
        Entity_fwy enFwy = JsonConvert.DeserializeObject<Entity_fwy>(PlayerPrefs.GetString("fwy", ""));
        Debug.LogError("cc:" + enFwy.name_fwy);
 
    }
 
  
}

3.多个gameObject数据存储

3.1实体类

public class DataSave
{
   
    public string obj_name;
 
    public int obj_id;
    public Vector3 obj_pos;
    public int obj_scale;
}

3.2list 转json 

/// <summary>
    /// list 转json 
    /// </summary>
    public static string ToJson<T>(this T list)
    {
        JsonSerializerSettings settings = new JsonSerializerSettings();
        settings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        return JsonConvert.SerializeObject(list, settings);
    }

3.3存储与解析

 
    [HideInInspector]
    public List<DataSave> list_sbHave = new List<DataSave>();
 
    public void dataSave( string str)
    {
        switch(str){
            case "sb":
            //string str = MyUtil.ToJson(list_dataHave_gt);
            string str = list_sbHave.ToJson();
            Debug.LogError("save:" + str);
            PlayerPrefs.SetString("have_sb", str);
            break;
        ......
    }
 
    public void DataGet()
    {
        string sb_str = PlayerPrefs.GetString("have_sb", "");
        if (string.IsNullOrEmpty(sb_str))
        {
            //默认拥有柜台
            DataSheBei ds1 = new DataSheBei
            {
                obj_name = "gt",
                obj_id = 12,
                obj_pos = new Vector3(-0.02f, 1.99f, -5),
                obj_scale = 1
            };
            PlayerPrefs.SetInt("barIndex", 0);
            list_sbHave.Add(ds1);
            //默认拥有1个四人桌
            DataSheBei ds2 = new DataSheBei
            {
                obj_name = "zy",
                obj_id = 1,
                obj_pos = new Vector3(-2.32f, 0.815f, -5),
                obj_scale = 1
            };
            PlayerPrefs.SetInt("tableIndex", 0);
            list_sbHave.Add(ds2);
        }
        else
        {
            JArray ja = (JArray)JsonConvert.DeserializeObject(sb_str);
            Debug.LogError("sb:" + ja.Count);
            for (int i = 0; i < ja.Count; i++)
            {
                DataSheBei ds = new DataSheBei();
                ds.obj_name = ja[i]["obj_name"].ToString();
                ds.obj_id = int.Parse(ja[i]["obj_id"].ToString());
 
                JObject jo = JObject.Parse(ja[i]["obj_pos"].ToString());
                ds.obj_pos = new Vector3(float.Parse(jo["x"].ToString()), float.Parse(jo["y"].ToString()), -5);
                ds.obj_scale = int.Parse(ja[i]["obj_scale"].ToString());
                list_sbHave.Add(ds);
            }
        }
 
        InitSbHave();
    ......
