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; } }

 

<?xml version="1.0" encoding="utf-8"?> <mx:Application layout="absolute" xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="onCreationComplete()"> <mx:Script> <!--[CDATA[ import cn.vicky.mco.Person; import cn.vicky.inter.Animal; import mx.core.UIComponent; import mx.core.ByteArrayAsset; // 嵌入car.swf文件 [Embed(source="assets/Car.swf", mimeType="application/octet-stream")] private var swf:Class; private var loader:Loader; private function onCreationComplete():void{ loader = new Loader(); // 转换为ByteArrayAsset var baAsset:ByteArrayAsset = ByteArrayAsset(new swf()); // 使用Loader组件载入二进制数据到当前Domain loader.loadBytes(baAsset, new LoaderContext(false,ApplicationDomain.currentDomain)); // 添加事件侦听器 loader.contentLoaderInfo.addEventListener(Event.COMPLETE,onload); createPerson(); } private function onload(e:Event):void{ var cls:Class; try{ // 取得swf文件中的Car类定义 cls = loader.contentLoaderInfo.applicationDomain.getDefinition("cn.vicky.mco.Car") as Class }catch(e:Error){ throw new IllegalOperationError("Definition not found"); } // 使用UIComponent将取得的Car实例添加到场景中 var uicar:UIComponent = new UIComponent(); var car:Object = new cls; uicar.addChild(car as DisplayObject); uicar.x=0; uicar.y = 200; addChild(uicar); } private function createPerson():void { var person:Animal = new Person(); var uiperson:UIComponent = new UIComponent(); uiperson.addChild(person as DisplayObject); uiperson.x = 50; uiperson.y = 50; addChild(uiperson); Person(person).username = "Vicky" person.eat(); person.sleep(); } ]]--> </mx:Script> </mx:Application>

 

运行后，打印：

Vicky can eat !
Vicky is sleeping !
