Godot 学习笔记(5):国际化多语言翻译，包含常用10种语言机翻！

本文主要是介绍Godot 学习笔记(5):国际化多语言翻译，包含常用10种语言机翻！，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

前言

为了面向更大的市场，国际化是肯定的。我想如果我开发游戏，至少要支持两种语言，英语和中文简体。

国际化

翻译Api选择

国内Api也有三种选择，百度，有道和小牛。我这里就选小牛了，比较便宜。

小牛测试

小牛翻译平台

使用PostMan测试成功

语言选择

首先，作为中文为母语，所以我至少支持三种语言。简中，繁中和英语。下面附上小牛的对应参数表

语言	参数
简中	zh
繁中	cht
英语	en
德语	de
法语	fr
西班牙语	es
意大利语	it
葡萄牙语	pt
俄语	ru
日语	ja
韩语	ko

吐槽一下，写了这么多，我都快认不清这个【语】字是什么意思了。

原文选择我这里选择英语作为原文，因为这样可以顺便学一下英语。

代码逻辑

这里使用了MiniExcel

Json化方式

实体对象

public class TranslateModel
{public TranslateModel() { }public TranslateModel(string scene,string key,string en) {Scene = scene;Key = key;EN = en;}public string Scene { get; set; }public string Key { get; set; }/// <summary>/// 英语/// </summary>public string EN { get; set; }/// <summary>/// 简体中文/// </summary>public string ZH { get; set; }/// <summary>/// 繁体中文/// </summary>public string CHT { get; set; }/// <summary>/// 德语/// </summary>public string DE { get; set; }/// <summary>/// 法语/// </summary>public string FR { get; set; }/// <summary>/// 西班牙语/// </summary>public string ES { get; set; }/// <summary>/// 意大利语/// </summary>public string IT { get; set; }/// <summary>/// 葡萄牙语/// </summary>public string PT { get; set; }/// <summary>/// 俄语/// </summary>public string RU { get; set; }/// <summary>/// 日语/// </summary>public string JA { get; set; }/// <summary>/// 韩语/// </summary>public string KO { get; set; }
}

翻译帮助类

public class TranslateHelper
{/// <summary>
/// 存放读取的数据
/// </summary>
public IEnumerable<TranslateModel> Translates { get; private set; }/// <summary>/// 模板路径/// </summary>public readonly string TemplateUrl = "Assests/translate_template.xlsx";/// <summary>/// 读取路径/// </summary>public readonly string ReadUrl = "Assests/translate_read.xlsx";/// <summary>/// 翻译导出路径/// </summary>public readonly string WriteUrl = "Assests/translate_read.xlsx";public TranslateHelper(){}}

导出模板

/// <summary>
/// 导出模板，如果文件存在则跳过
/// </summary>
public void CreateTemplate()
{if (!File.Exists(TemplateUrl)){var config = new OpenXmlConfiguration(){TableStyles = TableStyles.None};var saveTemplate = new List<TranslateModel>();saveTemplate.Add(new TranslateModel("Main", "Hello", "Hello World!"));MiniExcel.SaveAs(TemplateUrl, saveTemplate,configuration: config);}
}

读取文件

翻译

这里用一下我的封装

C# HttpClient Get Post简单封装

先来一个Hello world!翻译

public class TranslateHelper
{public enum Language { zh, cht, en, de, fr, es, it, pt, ru, ja, ko }/// <summary>/// 存放读取的数据/// </summary>public IEnumerable<TranslateModel> Translates { get; private set; }/// <summary>/// 模板路径/// </summary>public const string TemplateUrl = "Assests/translate_template.xlsx";/// <summary>/// 读取路径/// </summary>public const string ReadUrl = "Assests/translate_read.xlsx";/// <summary>/// 翻译导出路径/// </summary>public const string WriteUrl = "Assests/translate_read.xlsx";public const string API_KEY = "你的key";public const string APPID = "你的ip";public const string API_URL = "https://api.niutrans.com/NiuTransServer/translation";public TranslateHelper(){}/// <summary>/// 导出模板，如果文件存在则跳过/// </summary>public void CreateTemplate(){if (!File.Exists(TemplateUrl)){var config = new OpenXmlConfiguration(){TableStyles = TableStyles.None};var saveTemplate = new List<TranslateModel>();saveTemplate.Add(new TranslateModel("Main", "Hello", "Hello World!"));MiniExcel.SaveAs(TemplateUrl, saveTemplate, configuration: config);}}public void Read(){Translates = MiniExcel.Query<TranslateModel>(ReadUrl);}public async Task<string> TranslateFromEN(string en, Language language){//这个是我自己封装的，你也可以用微软官方的原生httpclientvar httpHelper = new MyHttpHelper(API_URL);var data = new{src_text = en,from = "en",to = language.ToString(),apikey = API_KEY,};var res = await httpHelper.JsonHttpPost<Dictionary<string,string>>("", data, null);var str = res["tgt_text"];return str;}}

测试

        static void Main(string[] args){var helper = new TranslateHelper();helper.CreateTemplate();Console.WriteLine("开始!");Task.Run(async () =>{var res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.zh);Console.WriteLine(res);});Console.WriteLine("结束!");Console.ReadKey();}

多语言测试

Task.Run(async () =>
{var res = "";res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.zh);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.cht);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.de);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.fr);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.es);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.it);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.pt);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.ru);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.ja);Console.WriteLine(res);res = await helper.TranslateFromEN("Hello world!", TranslateHelper.Language.ko);Console.WriteLine(res);
});

综合翻译

/// <summary>
/// 读取并写入机翻结果
/// </summary>
/// <returns></returns>
public async Task ReadAndWrite()
{if(!File.Exists(ReadUrl)){Console.WriteLine($"[{ReadUrl}]文件不存在，读取失败");return;}else{Translates = MiniExcel.Query<TranslateModel>(ReadUrl).ToArray();}if (File.Exists(WriteUrl)){Console.WriteLine($"[{WriteUrl}]文件已存在，跳过翻译");return ;}else{for(var i = 0;i< Translates.Count();i++){Console.WriteLine($"翻译进度：[{i}/{Translates.Count()}]");Translates[i] = await TranslateAllFromEN(Translates[i]);}//将数据保留MiniExcel.SaveAs(WriteUrl, Translates);}}/// <summary>
/// 从EN翻译全部
/// </summary>
/// <returns></returns>
public async Task<TranslateModel> TranslateAllFromEN(TranslateModel translateModel)
{if (translateModel.EN != null && translateModel.EN != ""){var en = translateModel.EN;translateModel.ZH = await TranslateFromEN(en, Language.zh);translateModel.CHT = await TranslateFromEN(en, Language.cht);translateModel.DE = await TranslateFromEN(en, Language.de);translateModel.FR = await TranslateFromEN(en, Language.fr);translateModel.ES = await TranslateFromEN(en, Language.es);translateModel.IT = await TranslateFromEN(en, Language.it);translateModel.PT = await TranslateFromEN(en, Language.pt);translateModel.RU = await TranslateFromEN(en, Language.ru);translateModel.JA = await TranslateFromEN(en, Language.ja);translateModel.KO = await TranslateFromEN(en, Language.ko);Console.WriteLine(JsonConvert.SerializeObject(translateModel));}else{Console.WriteLine($"Scene[{translateModel.Scene}],Key[{translateModel.Key}]的EN为空");}return translateModel;}/// <summary>
/// EN单独翻译
/// </summary>
/// <param name="en"></param>
/// <param name="language"></param>
/// <returns></returns>
public async Task<string> TranslateFromEN(string en, Language language)
{//防止请求过快,小牛API并发有限制await Task.Delay(100);//Console.WriteLine(language.ToString());var httpHelper = new MyHttpHelper(API_URL);var data = new{src_text = en,from = "en",to = language.ToString(),apikey = API_KEY,};var res = await httpHelper.JsonHttpPost<Dictionary<string,string>>("", data, null);var str = res["tgt_text"];return str;
}

文件准备

最终效果

翻译后

总结

多语言发布，这样可以让我们的游戏在更多的国家用户使用。虽然我暂时没有这个需求，但是说不定也有别的项目需要多语言的本地化接入。

这篇关于Godot 学习笔记(5):国际化多语言翻译，包含常用10种语言机翻！的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
