五子棋手机游戏开发需要安装，j2me环境，MyManagerPro.exe开发工具
需要创建三个类，棋子类，棋盘类，界面类
如果在jbuilder中开发，工具中自带有j2me插件功能，如果在myEclipse中开发，需要下载j2me插件
此类为Gobang.java
package com.occo.j2me.game.gobang;
import javax.microedition.lcdui.Display;
import javax.microedition.midlet.MIDlet;
public class Gobang extends MIDlet {
GobangCanvas gobang;//定义游戏界面的Canvas类GobangCanvas的对象gobang
public Gobang() {
super();
gobang=new GobangCanvas(this);//生成GobangCanvas类的对象gobang
}
protected void startApp(){
Display.getDisplay(this).setCurrent(gobang);
//在屏幕上绘出游戏见面gobang
}
protected void pauseApp(){
}
protected void destroyApp(boolean arg0){
}
}
此类为Chesses.java
package com.occo.j2me.game.gobang;
public class Chesses {
boolean isPlayer1;
public Chesses() {
}
public Chesses(boolean isPlayer1) {
this.isPlayer1=isPlayer1;
}
}
此类为GobangCanvas类
