立志一定要會用框架來寫東西阿！所以這次project改版，就決定用框架來寫，即使以前從來沒用過... 所以先從大家都在推的pureMVC開始，學了它，至少以後要改用其他語言來寫東西，他一樣可以用。剛開始真的非常不習慣，腦袋瓜子還在flex那個很好用的framework，拉一拉疊一疊就有東西可以跑的懶人作法。剛好看到隔壁有一本Head First Design Pattern，一整個有種挖到寶的感覺。預計三個禮拜的工作時間，大概超過一半都在念書學習跟trace code吧...

Object: *. 一個object最重要的兩個characteristics—state, behavior。(Real-World中的物件也是一樣的概念) *. State相當於一個物件所有的特徵。例如長度，高度，名稱，種類，顏色等等。 *. Behavior相當於這個物件能做的行為。例如跑，跳，說話，搖尾巴等等。 *. An object stores its state in fields (variables in some programming languages) and exposes its behavior through methods (functions in some programming languages). *. Hiding internal state and requiring all interaction to be performed through an object's methods is known as data encapsulation Class: *. Class相當於做出一個Object的藍圖或是模型，不是instance本身。 Inheritance: *. Common behavior can be defined in a superclass and inherited into a subclass using the extends keyword. Interface: *. Methods的集合，無implementation。 *. API: Application Programming Interface. Package: *. 用途相似的類別分門別類放在folder裡面。

新開個很冷的Tag，叫OO學OO，把念ActionScript的心得放這裡。 至於為什麼叫做OO學OO，(其正確念法為，圓圓學歐歐)那是因為，老是署名直接寫OO的敝人我，現在正在乖乖的學Object-Oriented的ActionScript。我的生活簡直充滿了圈圈阿～～～ 乖乖的從基本開始念，打底子。 先記下寫程式的金科玉律一條：One task per function. 這樣才能維持程式的乾淨與可讀性，當然，也才能徹底發揮OOP的優點。
