[AS3]心理测试题的开发

发布:kinglong | 发布时间: 2007年6月1日

    很久以前在《i时代报》看到心理测试题，就一直想开发这个好玩的程序！只是没时间开发，这次又报纸上看到测试题，突然又来兴趣了！这个程序逻辑我早就考虑过了，也不太难！正好用这个来练习自己对AS3编程感觉了！

    这次编程让我掌握了AS3中的XML，Stage，URLLoader，TextField，Sprite类的用法，还有AS3自带的组件使用。Flash帮助文件一直是我的老师，我的字典。它里面的调用实例一直很不错的。建议大家要养成看帮助文件的习惯，有些问题都可以在帮助文件中找到解决办法的，这个也是此次编程的心得。

   这个程序除使用Flash自带的组件外，其他全部是用代码实现的，而且采用了document class的方式，fla文件里没有一点代码。算是真正意义上的代码和设计分离吧!

Answer类

代码使用时，只要把"RadioButton","Button","ScrollPane"放到fla文件库就可以了，然后只在fla文件属性里设置document class值为"project.topic.Main"就可以了

所使用到的xml文件路径：“t1.xml” ，当然你也可以继续完善代码！
