这是本系统的一大亮点,也是Unity开发的一个神奇的特性。往往我们做的程序想要修改信息都要连接云服务器、数据库什么的,很少有能在本地直接修改的,并且修改完内置文件之后往往都会使程序崩溃,本系统使用的数据修改方法是将题目写在外部文档,使程序能够动态读取和修改题目信息。这种方式支持的文档格式可以是txt、xml、json,本系统用的是最简便的txt文本。
这是因为我们在Unity中新建一个StreamingAssets文件夹,这个文件夹中的内容可以在应用发布时原封不动地打包进去(不会被加密和压缩),一般用来存放二进制文件。
有了这个文件夹,我们就可以在打包完之后也可以进行文件中的修改(只限制于StreamingAssets文件夹)从而实现增删题目的功能。
唯一的限制就是添加修改题目要满足固定格式,不然读取会出现错误。
(按此路径找到题目文件)
