最近看到了一些五子棋，扫雷的代码讲解的文章，我也就写了个手机的象棋游戏，写的不是太全面，但还是能实现基本功能，共享出来供大家交流交流。
先介绍一下我的大体思路吧，我采用canvas让手机自己画出棋盘和棋子，而不是采用调用图片，虽然麻烦，但能锻炼自己的编程能力还能让算法简单，同时还能节省空间。具体的细节在代码中在说吧。首先要有一个主程序Game，这里比较简单，大家一看就能明白，我就不多说了．
import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
public class Game extends MIDlet {
GameCanvas game;//定义游戏界面的Canvas类GameCanvas的对象gobang
public Game() {
super();
game=new GameCanvas(this);//生成GameCanvas类的对象game
}
protected void startApp(){
Display.getDisplay(this).setCurrent(game);
//在屏幕上绘出游戏见面game
}
protected void pauseApp(){
}
protected void destroyApp(boolean arg0){
}
}
然后就是程序的主题部分了－－GameCanvas，这里实现了从画棋盘棋子一直到判断和输出．
我的主题思想是把棋盘初始化为一个2维数组，在有棋子的地方初始化为非0数，其他的都初始化为0；
大家可在代码中看到，在图象输出和棋子移动也都是基于这个数组进行的。
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;
public class GameCanvas extends Canvas implements CommandListener
{
protected Game game;
protected int empty;//屏幕右侧留的空间
protected int x;//棋盘输出的坐标
protected int cellWidth;//每个棋格的边长
protected int mapWidth,canvasW;//棋盘的宽度和画布的宽度
protected int a,b,c,d;//这是画炮下面的那几个折线，没什么用
protected int chessR;//棋子的半径
protected int selectedX,selectedY;//选择框在棋盘格局上的x,y位置
protected static int i,j;
protected int m,n,p;//记住开始的selectedX,selectedY和point[selectedX][selectedY]
protected String q;//记住word[selectedX][selectedY]
protected int guard,guard1,guard2,g,g1;//标记FIRE被按了多少次,g是用来判断走直线时前后的棋子,中间是否有其他棋子的累加器
protected static int g2,isRedWin,isWhiteWin;//g2表示该谁走了，后面那俩顾名思义了
protected Command exitCmd;
protected int point[][]={{1,2,3,4,5,6,7,8,9},//初始化INT数组
{0,0,0,0,0,0,0,0,0},

代码程序就是这些，看起来很麻烦吧，如果仔细看了的话，其实很简单，只不过象棋不比五子棋，规则太多了，但是我的代码里有很多缺陷，例如由于采用了canvas而不是gamecanvas，所以在paint()函数里面就会有很多的输出，这样在一些功能不强大的手机里会有闪屏的现象，我现在正在用gamecanvas写这个程序，大家先凑合看这个吧．还有，由于象棋游戏的自身因素，所以导致了只能在大屏幕手机上使用，我这个是针对ＷＴＫ２２的默认的彩色模拟器编的，而且都实现了，感觉效果还行，但是在一些其他的小屏手机上就不理想了，这个也没办法．
最后声明一下，大家可以拿我的代码转载，但毕竟是我的原创，请大家转载是把我的名字挂上-----dlut_608_#4,呵呵还有，代码太长了，没好好整理就发上来了，希望大家能耐心。
这个程序有很多需要赶紧的地方，希望大家看了以后多提宝贵意见．
