最近老是被一些底层的东西困扰着，老大说可能的话自己要做个编译器。嘿嘿，这两小罗那边也在叫嚣着自己做个小编译器，嘿嘿。。再者是最近项目里用到了as的正则表达式，非常恶心，反正还是不能满足目前自己的需求，而听老大说as的正则是用perl那的一套，什么版本我也搞不清了，所以也想看看AVM2的底层代码，底层的东西还是很好玩的。。结果发现其早就开源了，找到了篇外国人写的文章，也就不翻译了，直接贴出全文，相信牛人应该都看过了，，直接上地址。。

On November 7 at the Web 2.0 Conference in San Francisco, we announced that Adobe is contributing source code for the latest ActionScript Virtual Machine (AVM2) to the Mozilla Foundation. AVM2, the new scripting language engine for ActionScript 3.0 introduced with Flash Player 9, was designed to deliver the performance and features to support the needs of rich Internet application developers. The new open source project, known as Tamarin, will be hosted at mozilla.org and contributions will be managed by a governing body of developers from Adobe and Mozilla.
By partnering on the Tamarin open source project, Adobe and Mozilla hope to accelerate the adoption of a standard language for creating rich and engaging web applications. The Tamarin virtual machine will be implementing the final version of the ECMAScript Edition 4 (ES4) language specification. ECMAScript is a standards-based programming language widely used on the web—although you are more likely to be familiar with references to Adobe ActionScript, JavaScript, and Microsoft JScript than the name of the foundational standard these languages are based on. Adobe and Mozilla have been working together alongside other companies—such as Yahoo!, Apple, Microsoft, and Opera—on developing the ES4 language proposal as part of the Ecma International Programming Language technical committee (TC39-TG1).
"There is nothing better for a standard than to have it implemented in multiple products," said Secretary General Jan

将上次的源码进行修改一下，可以分离出一些共用的代码。
设计一个主角类，这个主角类实现了一个方向的接口。
player 实现IDirection4 的方向接口 ，意思就是代表上下左右四种方向，以及站立不动的接口。可 ......
