java代码实现俄罗斯方块

本文实例为大家分享了java实现俄罗斯方块的具体代码，供大家参考，具体内容如下

俄罗斯方块设计思想

俄罗斯方块都从小玩到大吧，什么规则大家都知道了吧，以前感觉那玩意贼好玩，但是就是老赢不了，现在学会了自己写一个天天练！

键盘操作：

左键：左移； 右键：右移；
上键：变换造型 下键：加速下掉（没毛病吧，没有继续整）

任意一行的方块满格，这一行就消除，消除一行方块得10分，目前小主我还没有设置关卡，各位喜欢的宝宝们可以自己设置关卡哦；

那么那些方块的造型到底从哪里来的呢，那就是我们自己设计的，常见的几种造型就是：i型，t型，l型，田字格型等等吧，自己个加呗！
那么到底咋整的咧？其实啊就是一个4*4的数组，当然了你开心设计n*n也可以，你牛皮你说了算！
那么下面举了一个例子，用来告诉你们为啥你们看见的造型可以变换的原因就是这样提前设计好，0为空，1为填充格，这样你就可以在你的游戏里面凹造型了！

算了：直接放图先看代码运行结果吧：

喜欢吗？喜欢就直接做吧，可能代码写的不够好，请各位大神多多包涵，我回头也会多总结，会不断更新代码的；

gamepanel类：游戏界面类，整个方块掉落和显示，游戏的逻辑斯洛都在这个类里面实现；

gameframe类：整个游戏的进入口，好吧，说白了就是有main()函数的类，这个类里面实现游戏界面的一些设计，你可以理解为一个小小小小的ui；

package tetris;

 private jmenuitem newgame = menuone.add("重新开始");//创建一个内置菜单选项
 private jmenuitem exitgame = menuone.add("游戏退出");
 private jmenuitem stopgame = menuone.add("游戏暂停");
 private jmenuitem goongame = menuone.add("游戏继续");

 private jmenu menutwo = new jmenu("帮助");//创建第二个菜单
 private jmenuitem aboutgame = menutwo.add("关于游戏");
 gamepanel gamepanel = new gamepanel();

 public gameframe()//构造函数
 {
 addkeylistener(gamepanel);
 newgame.addactionlistener(this);
 exitgame.addactionlistener(this);
 stopgame.addactionlistener(this);
 goongame.addactionlistener(this);
 aboutgame.addactionlistener(this);

 this.add(gamepanel);

 jmenubar menu = new jmenubar();
 menu.add(menuone);
 menu.add(menutwo);
 this.setjmenubar(menu);

 this.settitle("俄罗斯方块");
 this.setbounds(50, 10, widthframe, heightframe);
 this.setvisible(true);
 this.setdefaultcloseoperation(jframe.exit_on_close);

 }

 public void actionperformed(actionevent e)
 {
 if(e.getsource() == newgame)//游戏重新开始
 {
  gamepanel.newgame();
 }
 if(e.getsource() == exitgame)//游戏退出
 {
  system.exit(0);
 }
 if(e.getsource() == stopgame)//游戏暂停
 {
  gamepanel.stopgame();
 }
 if(e.getsource() == goongame)//游戏继续
 {
  gamepanel.continuegame();
 }
 if(e.getsource() == aboutgame)//关于游戏信息
 {
  joptionpane.showmessagedialog(null, "左右键移动，向上建旋转", "提示", joptionpane.ok_option);
 }
 }


 public static void main(string[] args) {
 new gameframe();
 }
}
