For 迴圈常用到的地方是律定”跑幾次”
While 迴圈則是用條件來控制”要不要離開迴圈”

for 控制次數
while 控制條件

Do – while 則是一定會進入一次…
但是當有設定條件時仍會依 是否符合條件才會進入迴圈

Let’s say, 人類,就是一個被定義好的物件, 而人類的職業就有點像是類別(class)

像是戰士(method)懂得作戰, 使用大劍(function), 魔術士具有魔法, 不管戰士或是魔術士都繼承了人類的

所有屬性(property)(皮膚顏色, 打的死…).  假使我們想讓戰士等級提升變的可以

使用其他技能(假設學會射箭), 就得給戰士一個轉職寶物(自訂類別), 這樣戰士就可以

使出百步穿楊的技能(定義好的弓箭手類別(class)中的精準命中技能(function)).

而戰士也具備有戰士原有的技能.

而在實作裡面來說就是

假使我們建立了一個影片片段來做一段火箭的動畫, 由於是從MovieClip類別中建立,

所以一開始就具備了MC的所有屬性(.x, .y, .alpha…) 那假使今天我想建立一個屬性

可以設定火箭的加速度(比如 .spped), 由於影片片段原本沒有speed屬性, 所以就必須

在外部檔案(當然寫在裡面也可以) 另外自訂一個類別, 並建立speed 這個屬性

這就是物件導向語法的基本概念

Package- Import a Class(.as) file into Flash(.fla).
封包程式- 把程式碼寫在外部as檔案, 需要的時候在呼叫

* The linkage name needs to be the same with Class file.

* Check this:

* A variable is a place to store information.
* Making data dynamic.

EX1:
var test:String
test = “hello”;
trace(test);

簡單一點也可以這樣寫

var test:String = “hello”;
trace(test);
_____________________

EX2:
var my_string:Number = 100;
var my_num:Number = 20;
trace(my_string + my_num);

也可以這樣寫

var my_string:Number = 100;
var my_num:Number = 20;
var my_answer:Number = my_string + my_num;
trace(my_answer);

Instance Name
* letter without space
* English only

Framerate
* recommended: 25-31
* most of computer cannot keep up with a framerate higher than 31fps
* Swf  runs slower on Mac Flash Player

Void
When it doesnt need to return anyting, just apply “void”
ex: put Number to instead of void, if it should return “numbers”

Function Syntax
property_btn.addEventListener(MouseEvent.MOUSE_DOWN,changeProperties);
The name of button (instance name)

The name if the function ( 從上一行來的名字)
function changeProperties(event:MouseEvent):void{
box_mc.x = 200;
box_mc.y = 200;
}

Number
* no need to be enclosed within (“)

int / Uint
* Only works in whole numbers.
<Some said The Number works faster, see here, or here.>

Array
* Arrays are lists of data under which each item is identified by its order within the list
* The first element in an Array has index 0

Boolean
* true or false
* default value is false

Object
* A lazy way.. Ex: var dw = document.write;

Custom Object
* A group of object. Ex: An apple contains smell, taste, color, and so on.

In CS4, action script 3, you can make a 3D movies.
Just insert a moive file to a Movie clip, then you can rotate the Movie Clip by “3D rotation tool”.
