Unity基础用C#脚本读取JSON文件数据

浏览数：52 / 时间：2015年06月09日

　　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;
    }
}

ConfigAchieveItem类代码：

    }

    public void loadDataFromJson(ConfigAchieve achieve, string key)
    {
        ConfigAchieveItem temp = (ConfigAchieveItem)achieve.GetItem(key);

        _configId = temp.Id;
        _configName = temp.Name;
        _configRace = temp.Race;

        _configTimes = temp.Times;
        _configImage = temp.Image;
    }
}

ConfigManager类代码：

using System;

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)

        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()
