上次初学AS3.0的时候，我充分利用了AS3 的OOP，实现2楼所说的，很直观，很好用，做了一个会走动会跳的简单Hero。。。

在Flash CS4我有define Land, Arm Hero Movieclip。
Land有很多个Frame，不同的frame代表不同的地形
Arm是Hero的手，Hero走路的时候Arm会摇动。
Hero可以向左向右，也可以跳。
我设定舞台的Main as file 为 LevelMain.as

package {
import flash.display.MovieClip;
import com.level.World;
import com.level.Config;
import com.level.Hero;
import com.level.Control;
import flash.events.Event;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
public class LevelMain extends MovieClip {
var config:Config = new Config();
var world:World = new World();
var hero:Hero = new Hero();
var control:Control = new Control();
public function LevelMain() {
initGame();
}
public function initGame():void {
config.configWorld(world);
config.configHero(hero);
config.configControl(control);
addChild(world);
addChild(hero);
this.addEventListener(Event.ENTER_FRAME, gameloop);
stage.addEventListener(KeyboardEvent.KEY_UP, control.key_up);
stage.addEventListener(KeyboardEvent.KEY_DOWN, control.key_down);
}
public function gameloop(e:Event):void {
heromove();
}
public function heromove():void {
var keyNames = control.getKeys();
if(keyNames.length > 0) {
for(var i:int; i<keyNames.length; i++) {
var keyName:String = keyNames[i];
if(keyName != null) {
hero.walk(keyName); // direction
}
}
} else {
hero.stops();
}
}
}
}

在 folder com/level define 了 5 个 class
Arm.as

package com.level {
import flash.display.MovieClip;
public class Arm extends MovieClip {
var _isSwing:Boolean = false;
public function Arm() {

public function startSwing():void {
this.gotoAndPlay(2);
_isSwing = true;

this.gotoAndStop(1);
