JSON相关

格式

对象表示为键值对 "age" : 10
数据逗号分隔
花括号保存对象
方括号保存数组

JSON 键/值对

配置文件:

一般游戏中的配置文件使用两种格式: json或者xml格式
为游戏运行提供数据支持

游戏策划:

数值 功能 总测

游戏中的数据: 固定(本地/基础 数据) 可变数据(玩家数据 )

解析配置文件

将json文件读取出来存成string
用过JsonUtility类将Json保存成对象

public class ReadTeaJson : MonoBehaviour {
    public AllItem allItem;
    // Use this for initialization
    void Start () {
        //将js读取到内存
        string jsonInfo = File.ReadAllText(Application.dataPath + @"\Scripts\Item.json"
        ,System.Text.Encoding.UTF8);
        //获取到了json对象的数组
        allItem = JsonUtility.FromJson<AllItem>(jsonInfo);
        //print(allItem.items[0].name);
    }
    
    // Update is called once per frame
    void Update () {
        
    }
    
}

[System.Serializable]
public class AllItem
{
    public Item[] items;
}
[System.Serializable]
public class Item
{
    public int id;
    public string name;
    public string describe;
    public string sprite_Name;
    public int price;
    public int type;
}

通过[System.Serializable]
进行串行化，将存储和读取文件、内存或其他地方中的对象，示例数据保存在存储介质上。

LitJson插件

通过插件生成Json文件

public class CreateJsonFromUnity : MonoBehaviour {

    // Use this for initialization
    void Start () {
        //JsonMapper

        CreateJson();
    }

    private void CreateJson()
    {

        JsonData jsonData = new JsonData();
        jsonData["age"] = 233;
        jsonData["name"] = "kk";
        jsonData["ItemBag"] = new JsonData();
        jsonData["WeaponBag"] = new JsonData();

        JsonData jsonData2 = new JsonData();
        jsonData2["item"] = new JsonData();

        JsonData jsonData3 = new JsonData();
        jsonData3["id"] = 1;
        jsonData3["name"] = "tulong";
        jsonData3["Description"] = "baodao";

        jsonData2["item"].Add(jsonData3);
        jsonData2["item"].Add(jsonData3);

        jsonData["ItemBag"].Add(jsonData2);
        //=================================
        JsonData jsonData4 = new JsonData();
        jsonData4["weapons"] = new JsonData();

        JsonData jsonData5 = new JsonData();
        jsonData5["id"] = 0;
        jsonData5["name"] = "轩辕剑";
        jsonData5["weaponAttribute"] = new JsonData();

        JsonData jsonData6 = new JsonData();
        jsonData6["atk"] = 0;
        jsonData6["def"] = 1;
        jsonData6["miss"] = 2;

        jsonData5["weaponAttribute"].Add(jsonData6);
        jsonData4["weapons"].Add(jsonData5);
        jsonData4["weapons"].Add(jsonData5);
        jsonData["WeaponBag"].Add(jsonData4);


        string json = jsonData.ToJson();
        json = ConvertJson(json);

        StreamWriter streamWriter = new StreamWriter(Application.dataPath + "PersonJson.Json");
        streamWriter.Write(json);
        streamWriter.Close();
        streamWriter.Dispose();

    }


    /// <summary>
    /// 编码转换
    /// </summary>
    /// <param name="jsonStr"></param>
    /// <returns></returns>
    public string ConvertJson(string jsonStr)
    {
        Regex reg = new Regex(@"(?i)\\[uU]([0-9a-f]{4})");
        string ss = reg.Replace(jsonStr, delegate (Match m) { return ((char)Convert.ToInt32(m.Groups[1].Value, 16)).ToString(); });
        return ss;
    }
}

class Person
{
    int age;
    string name;
    ItemBag itemBag;
    WeaponBag weaponBag;
}

internal class WeaponBag
{
    Weapon[] weapons;
}

internal class Weapon
{
    int id;
    string name;
    WeaponAttribute weaponAttribute;
}

internal class WeaponAttribute
{
    int atk;
    int def;
    int miss;
}

internal class ItemBag
{
    Item[] item;
}



internal class Item
{
    int id;
    string name;
    string description;
}

第二种方法进行写入Json，注意类的成员要全部public

private void CreateJsonNew()
    {
        Item item0 = new Item(0, "MP4", "Auto GUN");
        Item item1 = new Item(0, "AK47", "Auto GUN");
        Item[] items = new Item[] { item0, item1};
        ItemBag itemBag = new ItemBag(items);
        WeaponAttribute weaponAttribute = new WeaponAttribute(2, 3, 3);
        Weapon weapon0 = new Weapon(0, "HandGun", weaponAttribute);
        Weapon weapon1 = new Weapon(0, "HandGun", weaponAttribute);
        Weapon[] weapons = new Weapon[] { weapon0, weapon1 };
        WeaponBag weaponBag = new WeaponBag(weapons);

        Person kk = new Person(666, "kk", itemBag, weaponBag);
        //print(kk.)

        string json =  JsonMapper.ToJson(kk);
        json = ConvertJson(json);
        StreamWriter streamWriter = new StreamWriter(Application.dataPath + "/PersonJson.Json");
        streamWriter.Write(json);
        streamWriter.Close();
        streamWriter.Dispose();
    }

解析Json

private void ReadJson()
    {
        string jsonData = File.ReadAllText(Application.dataPath + "/PersonJson.Json");
        JsonReader jsonReader = new JsonReader(jsonData);
        Person mjsonData = JsonMapper.ToObject<Person>(jsonReader);
    }
