【Unity-學習-006】Unity 使用 JsonDotNet 插件,實現數據本地化

Unity商城裏有一個免費插件 JsonDotNet，可以實現以json文件的形式實現數據本地化。

這個插件支持自定義class的存儲，SaveData<T> 和 ReadData<T> 需要把要存儲的類型一塊傳過去。

 

以下是完整代碼。

public class DataHandle
{

    StreamWriter writer;
    StreamReader reader;
    string filePath = Application.persistentDataPath; //安卓路徑 是 android/data/xxx.xxx.xxx/file  


    //把所有的數據寫入文本中
    public void WriteIntoTxt(string message, string fileName)
    {
        FileInfo file = new FileInfo(filePath + "/" + fileName);
        if (!file.Exists)
        {
            writer = file.CreateText();
        }
        else
        {
            file.Delete();
            writer = file.CreateText();
        }
        writer.WriteLine(message);
        writer.Flush();
        writer.Dispose();
        writer.Close();
    }


    //讀取存儲到列表中
    public string ReadOutTxt(string fileName)
    {
        FileInfo file = new FileInfo(filePath + "/" + fileName);
        if (!file.Exists)
        {
            writer = file.CreateText();
            writer.Flush();
            writer.Dispose();
            writer.Close();

            return "nil"; //null 文件不存在並切已經剛剛創建了一個
        }


        reader = new StreamReader(filePath + "/" + fileName);
        string text;
        string str = "";
        while ((text = reader.ReadLine()) != null)
        {
            str += text;
        }

        reader.Dispose();
        reader.Close();

        return str;
    }

    //存儲數據
    public void SaveData<T>(T tempT, string fileName)
    {
        string str = JsonConvert.SerializeObject(tempT);
        WriteIntoTxt(str, fileName);
    }

    public void DeletData(string fileName)
    {
        FileInfo file = new FileInfo(filePath + "/" + fileName);
        if (file.Exists)
        {
            file.Delete();
        }
    }


    //讀取數據
    public T ReadData<T>(string fileName)
    {
        T tempT;
        string str = ReadOutTxt(fileName);
        if (str != "nil")
        {
            tempT = JsonConvert.DeserializeObject<T>(str);
        }
        else
        {
            tempT = default;
        }
        return tempT;
    }
