Unity翻译工具（使用百度翻译）

有时候临时改了加了一些中文，然后多语言那边没有及时给到外包翻译，这时候拿个百度翻译做一下翻译，不过简单的翻译还是可以用的。

http://api.fanyi.baidu.com/api/trans/product/apidoc 这个是百度翻译api文档

代码里面必须要加appid和password（秘钥）

上面地址打开管理控制台就可以申请，是免费的

如下图，最下面是appid和秘钥

 

工具在tool/翻译工具

打开之后执行翻译如下图

如果定义语言类型，这个枚举定义了几种具体可以看看下面截图

public enum Language
{
    zh,
    en,
    spa,
    fra,
    th,
    ara,
    ru,
    pt,
    de,
    el,
    vie,
    cht,
    yue,
}
