最近看到了一些五子棋，掃雷的代碼講解的文章，我也就寫(xiě)了個(gè)手機(jī)的象棋游戲，寫(xiě)的不是太全面，但還是能實(shí)現(xiàn)基本功能，共享出來(lái)供大家交流交流。

先介紹一下我的大體思路吧，我采用canvas讓手機(jī)自己畫(huà)出棋盤(pán)和棋子，而不是采用調(diào)用圖片，雖然麻煩，但能鍛煉自己的編程能力還能讓算法簡(jiǎn)單，同時(shí)還能節(jié)省空間。具體的細(xì)節(jié)在代碼中在說(shuō)吧。首先要有一個(gè)主程序Game，這里比較簡(jiǎn)單，大家一看就能明白，我就不多說(shuō)了．

import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
public class Game extends MIDlet {
    GameCanvas game;//定義游戲界面的Canvas類(lèi)GameCanvas的對(duì)象gobang
    public Game() {
        super();
        game=new GameCanvas(this);//生成GameCanvas類(lèi)的對(duì)象game
    }
    PRotected void startApp(){
        Display.getDisplay(this).setCurrent(game);
          //在屏幕上繪出游戲見(jiàn)面game
    }
    protected void pauseApp(){
    }
    protected void destroyApp(boolean arg0){
    }
}

然后就是程序的主題部分了－－GameCanvas，這里實(shí)現(xiàn)了從畫(huà)棋盤(pán)棋子一直到判定和輸出．
我的主題思想是把棋盤(pán)初始化為一個(gè)2維數(shù)組，在有棋子的地方初始化為非0數(shù)，其他的都初始化為0；
大家可在代碼中看到，在圖象輸出和棋子移動(dòng)也都是基于這個(gè)數(shù)組進(jìn)行的。

    protected Game game;

    protected int x;//棋盤(pán)輸出的坐標(biāo)
    protected int cellWidth;//每個(gè)棋格的邊長(zhǎng)
    protected int mapWidth,canvasW;//棋盤(pán)的寬度和畫(huà)布的寬度
    protected int a,b,c,d;//這是畫(huà)炮下面的那幾個(gè)折線，沒(méi)什么用
