Java实现游戏开发《俄罗斯方块》

一、用Java实现俄罗斯方块游戏：
1、效果图，如下图所示：
经典游戏-俄罗斯方块
7种形态的第一种形态, 如下所示：分布是：|、S、Z、J、O、L、T;
0 1 0 0 0 1 1 0 1 1 0 0 0 1 0 0 1 1 0 0 1 0 0 0 1 1 1 0
0 1 0 0 1 1 0 0 0 1 1 0 0 1 0 0 1 1 0 0 1 0 0 0 0 1 0 0
0 1 0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 1 1 0 0 0 0 0 0
0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
我在绘制图形的时候，让1的坐标绘制出来，0 不绘制；横数4位数，竖数4位数，16位数为一组形态；

1.1.需要新建窗口；
1.2.绘制游戏内容；
1.3.实现形状旋转功能；
1.4.实现形状的移动；（监听键盘事件）
1.5.实现图形自动降落；

2、首先创建java项目，web Project
3、创建项目成功后，添加一个class文件（文件名自定义命名）,代码如下：

package com.gx.games;

import java.util.Random;import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.Timer;/*** 俄罗斯方块游戏主体类* @author LXT**/
public class TetrisPanel extends JPanel implements KeyListener{TetrisPanel () {newBlock();newMap();drawWall();//调用画围墙方法Timer timer = new Timer(1000, new TimeListener());timer.start();//启动定时器}Random random = new Random();private int score = 0;private int delLineNum = 0;//定义方块的初始坐标；private int x;private int y;//shapes[0][1]private int blockType;//方块的类型 = random.nextInt(7)private int turnState;//方块的旋转状态 = random.nextInt(4)private int preBlockType = random.nextInt(7);private int preTurnState = random.nextInt(4);//定义方块的大小private int blockSize = 10;	//定义地图大小private int mapSizeX = 17;private int mapSizeY = 28;//定义地图int[][] map = new int[mapSizeX][mapSizeY];int i;int j;//地图中的值 0：没有  1：绘制形状 2：绘制围墙//定义形状private final static int shapes[][][] = new int[][][]{// |型{{0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0},{0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0},},// S型{{0, 1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},{0, 1, 1, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 0, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},},// Z型{{1, 1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0},},// J型{{0, 1, 0, 0, 0, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0},{1, 0, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0},{1, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},},// O型{{1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},},// L型{{1, 0, 0, 0, 1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0},{1, 1, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},{0, 0, 1, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},},// T型{{1, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0},{0, 1, 0, 0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},{1, 0, 0, 0, 1, 1, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0},}};/*** 产生新的形状*/public void newBlock(){//当前形状用预览形状代替blockType = preBlockType;turnState = preTurnState;//第三个preBlockType = random.nextInt(7);preTurnState = random.nextInt(4);//初始化xy坐标（方块的出现位置）x = 6;y = 0;if (gameOver (x, y) == 0) {newMap();drawWall();JOptionPane.showMessageDialog(null, "GAME OVER!");}}/*** 填充围墙*/public void drawWall(){for(i = 0;

4、然后在创建一个class文件（文件名自定义命名）,代码如下：

package com.gx.games;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.JOptionPane;public class LiuTetnis extends JFrame {public LiuTetnis () {TetrisPanel panel = new TetrisPanel ();addKeyListener(panel);add(panel);}public static void main(String[] args) {LiuTetnis frame = new LiuTetnis ();frame.setLocationRelativeTo(null); // 居中		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//点击关闭按钮，退出程序frame.setSize(270, 330);//设置窗体大小（高度和宽度）frame.setTitle("俄罗斯方块");//设置窗体标题//菜单栏JMenuBar menuBar = new JMenuBar();JMenu help = new JMenu("帮助");JMenuItem about = help.add("关于");menuBar.add(help);about.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {JOptionPane.showMessageDialog(null, "【俄罗斯方块练习版】作者：软件学院-liu");				}});frame.setJMenuBar(menuBar);//菜单栏frame.setVisible(true);//让窗体显示出来frame.setResizable(false);//不能调整窗口大小}}

5、然后在main方法里面的任意地方点击鼠标右键选择“Run AS”，选择“Java Application”,进行启动即可。
