今天开始做战斗，回合制战斗代码实现第一篇，从头开始，简单的2d回合制游戏

拖了这么久，终于弄到战斗系统了，不过仙剑demo的回合制战斗比较复杂，所以我们从最简单的2d回合制游戏战斗开始讨论，看看游戏战斗系统代码什么样子。

还记得回合制战斗的流程图吗，UI的时候我曾经贴过，，我们看下我们的战斗过程动画是什么样的，不要吐槽动画，我从神仙道用ps抠出来，没那么精细，反正不影响代码使用，我们直接看代码结构，这是bin目录也就是我们的生成目录（忘了说了，开发环境flashdevelop4.3，纯as3）lib路径下面fight.swc这个很重要（编译过程中需要里面的东西），因为fight.swc的底层写的很好，所以，我们的src代码相对简单，sampleBnt.as是我写的一个按钮类（比较简陋），main.as文档类（这是我们工程的代码入口类），fightmap.as战斗地图类，fightstarttip.as是我们的数据解析，战斗状态判断类，npc文件夹下面是控制动画和战斗逻辑部分，我们上代码，

package
{import BtnTip.SampleBnt;import com.FightTip.FightStartTip;import flash.display.Sprite;import flash.events.Event;/*** ...* @author swordfishx*/[SWF(width="1250",height="650",frameRate="24",backgroundColor="0")]public class Main extends Sprite{public function Main():void{if (stage)init();elseaddEventListener(Event.ADDED_TO_STAGE, init);}private function init(e:Event = null):void{removeEventListener(Event.ADDED_TO_STAGE, init);// entry pointaddChild(new FightStartTip());}}}

文档类没有什么东西，这里我们把fightStartTip类addchlid到舞台中，

package com.FightTip
{import flash.display.Sprite;import com.ot.FightMap;import com.ot.BaseRemove;import com.npc.XMLLoader;import flash.events.MouseEvent;import flash.display.Loader;import flash.events.Event;import flash.net.URLRequest;import flash.net.URLLoader;import flash.geom.Point;import flash.system.System;/*** ...* @author swordfishx*///[SWF(width="1250",height="650",frameRate="24",backgroundColor="0")]public class FightStartTip extends Sprite{private var _fight_mc:Sprite;//xml载入类private var loader:XMLLoader;private var _i:int = 0;public function FightStartTip(){System.useCodePage = true;//载入属性Xmlloader = new XMLLoader();loader.onLoadComplete = initMap;loader.load("data/fight/fight.xml", XMLLoader.GB2312);}public function initMap(xml:XML):void{_fight_mc = new Sprite();addChild(_fight_mc);fightStart("fight002");}//战斗开始public function fightStart(mapValue:String = "", fun:Function = null):void{//通过名称显示相应地图var fightmap:FightMap = new FightMap("data/fight/" + mapValue + ".xml", fun, this);_fight_mc.addChild(fightmap);}//战斗结束public function fightEnd(fun:Function):void{overEnd();//BaseRemove.removeAllChildren(_fight_mc);//_fight_mc.visible = false;//fun();}public function overEnd():void {trace("到这里就先结束了。");try {dispatchEvent(new Event("FightStartTipSTR"));trace("发送成功");} catch (err:Error) {trace("没有发送");}}}}

上面的流程图很清楚，这里的数据应该填写的地方，我们看下fightstart方法，参数fight002，我们看下这个xml配置文件里面写了什么，

<?xml version="1.0" encoding="GB2312"?>
<data><map>fight02.jpg</map><our><list>jianyu</list><list>daji</list></our><enemy><list>shibing</list><list>shibing</list><list>shibing</list></enemy>
</data>

fight02.jpg是背景图，<our>是我方阵营，<enemy>是敌方，这个xml可以根据list的增减进行拓展（网络的话，只需要在解析部分修改一下，把赋值过程从xml解析改成网络监听方法解析的字符串就可以了），

package BtnTip
{import flash.display.Shape;import flash.display.Sprite;import flash.display.SimpleButton;import flash.text.TextField;import flash.text.TextFormat;/*** ...* @author swordfishx*/public class SampleBnt extends Sprite{public function SampleBnt(acol:uint = 0xffffff, bcol:uint = 0xffffff,ccol:uint = 0xffffff,Str:String = "btn", tfcol:uint = 0xffffff):void{var a:Sprite = new Sprite();huitu(a, acol, Str, tfcol)var b:Sprite = new Sprite();huitu(b, bcol, Str, tfcol);var c:Sprite = new Sprite();huitu(c, ccol, Str, tfcol);var abc:SimpleButton = new SimpleButton(a, b, c, c);addChild(abc);}public function huitu(obj:Sprite, col:uint = 0xffffff, str:String = "btn", tfcol:uint = 0xffffff):void{obj.graphics.beginFill(col);obj.graphics.drawRect(0, 0, 80, 30);obj.graphics.endFill();var lable:TextField = new TextField();lable.text = str;lable.width = 80;lable.height = 30;var tf:TextFormat = new TextFormat();tf.bold = true;tf.size = 24;tf.color = tfcol;lable.selectable = false;lable.setTextFormat(tf);obj.addChild(lable);}}}

这是个简陋的画按钮方法，当然可以自己修改，把里面的huitu方法改成图片，或者在里面直接加一个就行了，

图像处理类，我们bin文件夹里面的序列图片，在这个类里面被分割，生成动画（如果使用cocos2dx和u3d的话，可以直接做动画，当然flash也可以，当时做的时候就是一个评估，因为游戏最终流产，所以没有做更好的效果，这里见谅，只是给大家提供个思路），

其实整个事例最重要的类莫过于上面这个fightmap累了，回合制游戏的状态机基本代码都在上面（参考了一个成熟的回合制游戏），开发回合制游戏的话，建议按照上面这个类重写一下，比如使用u3d（或者cocos2dx），可以先作出2d动画，然后按上面这个类的思路对动画进行操作，因为本身代码量不大，而且注释很详细，所以也不多说了，
