Unity多语言本地化改进版
来源：互联网 发布：微交易平台软件开发 编辑：程序博客网 时间：2024/05/16 08:15
简介
之前捣鼓过一个通过csv配置游戏多语言支持的小工具，但是发现使用过程中，通过notepad++去进行转码很不方便，并且直接将配置的csv不加密的放在游戏中心里感觉不是很踏实
于是乎~~
新的方案
1.在PC/MAC平台上解析多语言配置，也就是editor运行环境中解析csv或者excel
2.通过在Editor运行过程中生成多个语言对象，然后序列化并加密存盘
3.在使用端（移动端）通过resources加载加密之后的文件
4.读取对应的语言序列化文件并实例化加载到游戏中进行使用
使用方法
由于不想让csv文件被打包入游戏工程中，所以选择与Assets文件夹并列的路径文件：
PS:当然路径可以自己指定 
然后里面存放多语言csv 
然后代码中是调用是这样的：

感觉比上一个版本好了很多
1.不用考虑csv编码的问题了
2.反序列化速度比读取csv更快
3.加了密更可靠
4.不同语言分开读取，占用内存更小
缺点嘛，暂时觉得还不错~~继续先用着，有问题再改
