AVG只是下属分支中的一环罢了AVG包含GalGame但GalGame并不能完全代表AVG/ADV。另外关于GalGame的详细介绍在若木民喜《只有神才知道的世界》中演绎的相当生动有兴趣的可以自己去看看~ 就技术角度而言AVG开发可以算得所有游戏类型中最容易的。一款简单AVG游戏的制作难度甚至在贪食蛇、俄罗斯方块之下。由于实现的简易性导致AVG的开发重心往往着重于策划及美工程序员的作用则微乎其微。同时也正因AVG开发的门坎约等于0所以此类型的同人游戏之多即可堪称世界之冠。另外AVG开发工具普及的也促进了AVG的量产化。利用工具即始是小说作者、漫画家等非软件专业出身的人士往往也能轻易制作出顶级的AVG大作。顺便一提目前我所见过最好的AVG制作工具是鬼子的livemaker采用类似思维导图的方式构造整个游戏很多轻小说作者乃至网络漫画家用它制作自己作品的宣传游戏。但就技术角度上说livemaker的开发依旧没什么难度...... 由于AVG的大泛滥通常仅有文字、图片及语音的AVG往往无法满足用户需求H除外-_-。我们每每可在AVG游戏类型后发现个号比如《樱花大战》是AVGSLG《生化危机》是AVGACT。所以客观上说AVG开发仅仅能进行字图的交互是不够的还要解决多模块组件的协调问题。 在Java桌面应用开发中,我们都知道绘图是极为简单的有Image、Graphics两个对象就可以Paint一个图形即使图形对象再多最后它们也必须统一在一个Paint中所以Java中不存在图像的交互问题。 但问题在于图像的显示可以统一但是触发图像变化的事件却是很难统一的。比如现在有需求如下在AVG模式中触发键盘事件上、下、左、右时为控制画面的前进、后退切换模式到SLG模式后设定上、下、左、右是光标移动那么如果我要在程序中实现就必须记录当前模式而后根据不同模式调用事件再反馈到图形上。如果只有几个事件的区别我们当然可以很容易用分支来实现问题是随着游戏规模的加大这些分支将成几何倍数增多单纯的分支判定到最后只能忙于应付落个费力不讨好。 其实在这时我们大可以使用一些技巧来轻松解决问题。 示例如下 首先我们构造一个接口命名为IControl继承鼠标及键盘监听并在其中设定两个抽象方法 package org.loon.simple.avg; import java.awt.Graphics; import java.awt.event.KeyListener; import java.awt.event.MouseListener; import java.awt.event.MouseMotionListener; /** * Copyright 2008 - 2009 * * Licensed under the Apache License, Version 2.0 (the License); you may not * use this file except in compliance with the License.
