一个象棋手机游戏的源代码

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},
              {0,10,0,0,0,0,0,11,0},
        {12,0,13,0,14,0,15,0,16},
