Unity 用C#脚本读取JSON文件数据

　　读取JSON文件数据网上有很多方法吗，这里采用SimpleJSON，关于SimpleJSON的介绍参考以下链接：http://wiki.unity3d.com/index.php/SimpleJSON，使用之前要先导入SimpleJSON的相关文件。

JSON文件名：achieve.json，文件内容：

{



"30002":{"achieve_id":30002,"achieve_name":"连胜","achieve_race":3,"achieve_type":41,"achieve_des":"排位赛连续胜利10场","achieve_gold":20,"achieve_times":10,"image":"athletics_2"},

"30003":{"achieve_id":30003,"achieve_name":"百战百胜","achieve_race":3,"achieve_type":41,"achieve_des":"排位赛连续胜利100场","achieve_gold":100,"achieve_times":100,"image":"athletics_3"},

"30004":{"achieve_id":30004,"achieve_name":"不屈","achieve_race":3,"achieve_type":42,"achieve_des":"排位赛连续失败10场","achieve_gold":5,"achieve_times":10,"image":"athletics_4"}



     }

这里直接贴出脚本代码：

ConfigAchieve类代码：

using UnityEngine;

using System.Collections;



using SimpleJSON;



public class ConfigAchieve

{

    private Hashtable hash = new Hashtable();  



    // 从Json文件中载入信息保存至Hashtable

    public void loadFromJson(JSONNode data)

    {

        if (data == null)

            Debug.Log("read faild");

        else

        {

            for(int i=0 ; i<data.Count; i++)

            {

                ConfigAchieveItem node = new ConfigAchieveItem();



                node.Id = data [i] ["achieve_id"];

                node.Name = data [i] ["achieve_name"];

                node.Race = data [i] ["achieve_race"];

                node.Type = data [i] ["achieve_type"];

                node.Des = data [i] ["achieve_des"];

                node.Gold = data [i] ["achieve_gold"];

                node.Times = data [i] ["achieve_times"];

                node.Image = data [i] ["image"];



                hash.Add(node.Id, node); 

            }

        }

    }



    // 从Hashtable中返回键为key的值

    public ConfigAchieveItem GetItem(string key)

    { 

        ConfigAchieveItem itemAchieve = (ConfigAchieveItem)hash[key];

        return itemAchieve;

    }

}

ConfigAchieve

ConfigAchieveItem类代码：

using System;

using SimpleJSON;



public class ConfigAchieveItem

{

    private string _configId = "";

    private string _configName = "";

    private string _configRace = "";

    private string _configType = "";

    private string _configDes = "";

    private string _configGold = "";

    private string _configTimes = "";

    private string _configImage = "";



    public string Id

    {

        get { return _configId; }

        set { _configId = value; }

    }

    

    public string Name

    {

        get { return _configName; }

        set { _configName = value; }

    }

    

    public string Race

    {

        get { return _configRace; }

        set { _configRace = value; }

    }

    

    public string Type

    {

        get { return _configType; }

        set { _configType = value; }

    }

    

    public string Des

    {

        get { return _configDes; }

        set { _configDes = value; }

    }

    

    public string Gold

    {

        get { return _configGold; }

        set { _configGold = value; }

    }

    

    public string Times

    {

        get { return _configTimes; }

        set { _configTimes = value; }

    }

    

    public string Image

    {

        get { return _configImage; }

        set { _configImage = value; }

    }



    public void loadDataFromJson(ConfigAchieve achieve, string key)

    {

        ConfigAchieveItem temp = (ConfigAchieveItem)achieve.GetItem(key);



        _configId = temp.Id;

        _configName = temp.Name;

        _configRace = temp.Race;

        _configType = temp.Type;

        _configDes = temp._configDes;

        _configGold = temp.Gold;

        _configTimes = temp.Times;

        _configImage = temp.Image;

    }

}

ConfigAchieveItem

ConfigManager类代码：

using System;

using System.Collections;

using System.Collections.Generic;

using System.IO;

using UnityEngine;

using SimpleJSON;



public class ConfigManager : MonoBehaviour

{

    public ConfigAchieve _config_achieve = new ConfigAchieve();



    // Use this for initialization

    void Start()

    {

        Test(); // 测试函数

    }

    

    // Update is called once per frame

    void Update()

    {   

    }



    // 打开对应路径的json文件

    public JSONNode jsonFromFile(string filename)

    {

        JSONNode json_object = null;

        TextAsset filePath = (TextAsset)Resources.Load(filename);

        

        if (filePath == null)   // Json文件读取失败，打印日志

            Debug.Log("find json file faild!");

        else

            json_object = JSON.Parse(filePath.text);    // 转为json格式



        return json_object;

    }



    public void Test()

    {

        _config_achieve.loadFromJson(jsonFromFile("Config/achieve"));

        ConfigAchieveItem temp = _config_achieve.GetItem("10001");



        Debug.Log("id = " + temp.Id + " name = " + temp.Name);

        Debug.Log("race = " + temp.Race + " type = " + temp.Type);

        Debug.Log("des = " + temp.Des + " gold = " + temp.Gold);

        Debug.Log("times = " + temp.Times + " image = " + temp.Image);

    }

}

ConfigManager　　

　　其中ConfigManager用来控制打开json文件，ConfigAchieve用来读取数据，ConfigAchieveItem用来保存每条数据然后就可以用代码中的Test函数来测试读取是否正确。（很久了，大概是这个样子~~）
