嗯…一般来说做游戏啥的都不会只发一个国家,但是每个国家语言不同,就存在多语言本地化的问题,然后直接用过一个通过xml完成本地化的东东,然后策划反馈不会修改xml,扔给我一个excel让我自己把字段填进去,然后我就自己写个csv的本地化工具….
PS:至于为啥用csv不用xls或者xlsx,因为!csv格式简单啊,自己就可以写解析器,excel的解析去又需要一大堆第三方库啥的
先在Assets/Resources文件夹下创建一个LTLocalization文件夹,然后在里面创建一个Localization.csv文件
然后通过wps或者excel编辑
像这样:
然后将csv文件转换成UTF-8编码格式
// 直接使用,会自动判断当前系统语言
LTLocalization.GetText(Key);
// 手动指定语言使用
LTLocalization.ManualSetLanguage(SystemLanguage.language);
LTLocalization.GetText(Key);
这个用法还算简单吧…
1.通过csv解析器将CSV文件整体读到内存中
2.转换为相应的table表格
3.根据需要的语言将对应的数据提取出来形成一个dictionary
4.通过dictionary需要需要的本地化语言

1.读取csv的时候是一次性全部读取到内存中,对于大文件可能会出问题
2.对于有中文的文件只支持UTF-8的格式,需要手动转换成UTF-8编码
其实还是高估的自己的代码突破能力,本来想通过File去读取的
结果发现unity打包支持的文件无法进行正常的File读取
只能使用unity自带的TextAsset文件类型去支持,然后就只支持UTF-8了
以后有机会的话再优化吧,先用着…
