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 = MyUtil.ToJson(list_dataHave_gt);
        string str = list_sbHave.ToJson();
        Debug.LogError("save:" + str);
        PlayerPrefs.SetString("have_sb", str);
    }

    public void DataGet(string sbType)
    {
        switch (sbType)
        {
            case "gt":
                string st = PlayerPrefs.GetString("have_sb", "");
                JArray ja = (JArray)JsonConvert.DeserializeObject(st);
                Debug.LogError("ja:" + ja.Count);
                for (int i = 0; i < ja.Count; i++)
                {
                    DataSave ds = new DataSave();
                    ds.obj_name = "gt";
                    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);
                }
                foreach (DataSave ds in list_sbHave)
                {
                    Debug.LogError(ds.obj_name + "..." + ds.obj_id + "..." + ds.obj_pos.ToString() + "..." + ds.obj_scale.ToString());
                }
                break;
        }
    }
