flash中三维动画学习(关于类)
这几天认真学习了flash中,action script,虽然他无法与.net相比,不过同样是面对对象的语言,
实在是体会了这个思想的伟大,我是学习了Robert Peners的文章,现在负上一个试验,几个类的源码
,由于是初学,请见谅
在vectors.as中
只是定义几个关于坐标转换的function,但是实际的效果太出乎意料了,虽然我血flash才短短的11天
但是我已经被深深吸引了,有在c#的基础,action script实在太简单,学起来相当容易,毕竟他现在还不
是
真正面对对象的语言,不知道,我都快放弃.net了,要是大家有建议请告诉我,谢谢!!
请问asp.net能不能和flash产生交互,我只知道和php,能进行交互,在asp.net条件下,要是能行的话,就太好了
z这是三维的类
