引言：

俄罗斯方块的代码实现很简单，很有意思！

思路：

1、创建主窗口，加载菜单及游戏面板。

2、在游戏面板中初始化各种参数，并建立各种功能组件。

3、利用paint()函数开始画方块。

4、游戏结束，收尾，准备下一局。

本游戏用的是JDK1.8，编码UTF-8；

共有5个类，Gobang.java是游戏入口类。GameFrame.java是主窗口类。GamePanel.java是游戏面板类。GameLogic.java是游戏逻辑类。先一口气把所有的代码贴上来再说。

1、Tetris.java 游戏入口类

package com.game.tetris;/*** 功能：俄罗斯方块<br>* 作者：我是小木鱼（Lag）<br>*/
public class Tetris 
{public static void main(String[] args){new GameFrame();}}

2、GameFrame.java 主窗口类。

package com.game.tetris;import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;/*** 功能：游戏窗口<br>* 作者：我是小木鱼（Lag）<br>*/
public class GameFrame extends JFrame implements ActionListener
{private static final long serialVersionUID = 1L;/** 游戏面板 */private GamePanel gamePanel;/*** 功能：构造函数<br>*/public GameFrame(){try{//菜单JMenuBar jmb_tetris = new JMenuBar();JMenu jm_game = new JMenu("游戏");JMenuItem jmi_game_new = jm_game.add("新游戏");jmi_game_new.addActionListener(this);jmi_game_new.setActionCommand("new");JMenuItem jmi_game_pause = jm_game.add("暂停");jmi_game_pause.addActionListener(this);jmi_game_pause.setActionCommand("pause");JMenuItem jmi_game_continue = jm_game.add("继续");jmi_game_continue.addActionListener(this);jmi_game_continue.setActionCommand("continue");jm_game.addSeparator();JMenuItem jmi_game_exit = jm_game.add("退出");jmi_game_exit.addActionListener(this);jmi_game_exit.setActionCommand("exit");jmb_tetris.add(jm_game);JMenu jm_help = new JMenu("帮助");JMenuItem jmi_help_about = jm_help.add("关于");jmi_help_about.addActionListener(this);jmi_help_about.setActionCommand("about");jmb_tetris.add(jm_help);this.setJMenuBar(jmb_tetris);//面板this.gamePanel = new GamePanel();this.add(this.gamePanel);//显示this.setTitle("俄罗斯方块");this.setSize(400,500);this.setResizable(false);this.setLocationRelativeTo(null);this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);this.setVisible(true);}catch(Exception e){JOptionPane.showMessageDialog(this,"程序出现异常错误，即将退出！\r\n\r\n"+e.toString(),"提示",JOptionPane.ERROR_MESSAGE);System.exit(0);}}/*** 功能：事件监听<br>*/@Overridepublic void actionPerformed(ActionEvent e){String command = e.getActionCommand();if("new".equals(command)){this.gamePanel.newGame();}else if("pause".equals(command)){this.gamePanel.pauseGame();}else if("continue".equals(command)){this.gamePanel.continueGame();}else if("exit".equals(command)){System.exit(0);}else if("about".equals(command)){JOptionPane.showMessageDialog(this,"左右键移动，向上键旋转！\r\n\r\n我是小木鱼（Lag）\r\n\r\n","提示",JOptionPane.INFORMATION_MESSAGE);}}}
