Unity3D教程：Streaming Assets路径-Toy模板网

这篇具有很好参考价值的文章主要介绍了Unity3D教程：Streaming Assets路径。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

我们在读写例如XML和TXT文件的时候，在电脑上和手机上路径不一致，造成了很多麻烦，其实有个简单的方法，在项目工程中新建一个StreamingAssets文件夹，把你的XML和TXT文件放到这里。

注：其实每个平台的路径都可以是Application.streamingAssetsPath+“/Achievement.xml”。但是android平台必须要用WWW加载。文章来源地址https://www.toymoban.com/news/detail-588431.html
