Flash分模块开发，Flash分模块加载，以及使用Flex经行游戏开发！

     目前我主要使用的flash，ActionScript开发IDE为：Flex builder3/4，Flash CS3/4，FlashDevelop3.

 

    一个游戏项目：如果不分模块开发，一个主程序会是相当的庞大，且不容易维护与多人并行开发。

 

    分模块开发主要涉及到ActionScript面向接口开发。

 

    一个程序员在经行一块开发的时候，应当将涉及的对象面向接口，而主程序只需要存在同样的接口，而不需要接口具体实现的类。虽然主程序与单块模块都同时存在这个接口，编译后的swf也许会大一点，但相对于其有点，这可以完全忽略。

 

    将Flash编写的游戏会使用的元件等，编译生成.swf文件

接口：

package application.view.components.ui.chat.base{public interface IChat{function show(app:Object):void;function setMessage(kind:String,msg:String):void;}}

 

核心代码：

 

var loader:SWFLoader=new SWFLoader();loader.Load("assets/ui/chat/mc_chat_world.swf");loader.addEventListener(Event.COMPLETE,function(event:Event):void{// 获得非主程序中的其他类，通过swf获得var ChatBig:Class=loader.GetClass("application.view.components.ui.chat.cls.ChatBig",loader.loadinfo);chatUI = new ChatBig() as IChat;chatUI.show(App.getApp());App.getApp().chatFactory.bigChar = chatUI;});

使用ChatBig的时候： (ChatBig as IChat).show(XXXXX);

Flex使用ActionScript Project开发游戏。

由于Flex的MXML中，addChild(mx.core.IUIComponent)无法使用MovieClip。故Flex开发游戏开发游戏是基于Sprite的。这是鄙人的错误，FlexMXML中使用Flash自定义组件方式，请参见后面！

 

 将Flash编写的游戏会使用的元件等，编译生成.swc文件.再ActionScript Project中ActionScript Build Path-->Library Path-->Add SWC

 

直接使用.swc中的类。

 

 

 

附带常用的类SWFLoder

/* * SWF加载 */package cn.vicky.as3.utils{import flash.display.Loader;import flash.display.LoaderInfo;import flash.events.Event;import flash.events.EventDispatcher;import flash.events.IOErrorEvent;import flash.events.ProgressEvent;import flash.events.SecurityErrorEvent;import flash.net.URLRequest;import flash.system.ApplicationDomain;import flash.system.LoaderContext;/** * SWF加载器 */public class SWFLoader extends EventDispatcher{private var m_loadinfo:LoaderInfo;public function get loadinfo():LoaderInfo{return m_loadinfo}public function SWFLoader() {}/** 加载SWF */public function Load(url:String):void {var loader:Loader = new Loader();var context:LoaderContext = new LoaderContext();/** 加载到子域 */context.applicationDomain = new ApplicationDomain(ApplicationDomain.currentDomain);InitLoadEvent(loader.contentLoaderInfo);loader.load(new URLRequest(url),context);}/** * 获取当前ApplicationDomain内的类定义 * * name类名称，必须包含完整的命名空间,如 Grave.Function.SWFLoader * info加载swf的LoadInfo，不指定则从当前域获取 * return获取的类定义，如果不存在返回null */public function GetClass(name:String, info:LoaderInfo = null):Class {try {if (info == null) {return ApplicationDomain.currentDomain.getDefinition(name) as Class;}return info.applicationDomain.getDefinition(name) as Class;} catch (e:ReferenceError) {//trace("定义 " + name + " 不存在");return null;}return null;}/** * @private * 监听加载事件 * * @param info加载对象的LoaderInfo */private function InitLoadEvent(info : LoaderInfo):void {info.addEventListener(ProgressEvent.PROGRESS, this.onProgress);info.addEventListener(Event.COMPLETE, this.onComplete);info.addEventListener(IOErrorEvent.IO_ERROR, this.onError);info.addEventListener(SecurityErrorEvent.SECURITY_ERROR, this.onError);}/** * @private * 移除加载事件 * * @param inft加载对象的LoaderInfo */private function RemoveLoadEvent(info:LoaderInfo):void {info.removeEventListener(Event.COMPLETE,onComplete);info.removeEventListener(ProgressEvent.PROGRESS,onProgress);info.removeEventListener(IOErrorEvent.IO_ERROR,onError);info.removeEventListener(SecurityErrorEvent.SECURITY_ERROR,onError);}/** 加载事件 */private function onComplete(e:Event):void {var info:LoaderInfo = e.currentTarget as LoaderInfo;RemoveLoadEvent(info);m_loadinfo = info;this.dispatchEvent(e);}/** 加载中 */private function onProgress(e:ProgressEvent):void {this.dispatchEvent(e);}/** 出错事件 */private function onError(e:Event):void {this.dispatchEvent(e);}}}

 

 

对比

 

[Embed(source="../Assets/NearHill1.swf")] var NearHill1:Class; [Embed(source="../Assets/NearHill2.swf")] var NearHill2:Class;var url1:String = "Assets/NearHill1.swf";//var url2:String = "Assets/NearHill2.swf";//var urlReq:URLRequest = new URLRequest(url1);//var urlReq2:URLRequest = new URLRequest(url2);//var loader:Loader = new Loader();new NearHill1();

 

错误更正：

 

Flex使用MXML同样能加入使用Flash自定义的组建！

 

package cn.vicky.mco{import flash.display.MovieClip;public class Car extends MovieClip{public function Car(){super();}}}

 

package cn.vicky.mco{import cn.vicky.inter.Animal;import flash.display.MovieClip;public class Person extends MovieClip implements Animal{public var username:String ;public function Person(){super();}public function eat():void{trace(username + " can eat !");}public function sleep():void{trace(username + " is sleeping !");}}}

 

package cn.vicky.inter{public interface Animal{function eat():void;function sleep():void;}}
