五、总结

说明

该课设一共分成8个类，分别是Check_mark、Double_Login、Double_People、Login、Mark_user、MUSIC、prinBall、主页面。另外还有一个放在桌面的文件夹存放音乐文件和主界面的背景图和连接mysql的数据库，具体说明放后面这样程序才能完全运行

一、游戏概述

弹珠传说是一个基于java swing的弹球小游戏，运行程序后允许用户选择执行选项菜单。双缓冲就是在内存中开辟一片区域，作为后台图像，程序对他进行更新、修改绘制完成后再显示到屏幕上。可以简单地这样理解，将开辟区域可以理解为新建一个图层，然后将之前所建立的图片图层都放在这个图层上面，然后最他们进行合并图层合并成一个图层，然后不管再怎样刷新渲染，几个图像组件都是保持一致的，出现频率不一样的情况也就不会出现了。本设计的主要实现功能是通过双缓冲技术绘制弹珠小球，键盘控制滑块让弹珠能够弹射到墙面得分，并不断升级游戏难度，记录最终得分上传至数据库中进行排序，实现了单人模式和双人合作模式。

二、需求分析

当前各种游戏层出不穷，因为游戏的开发成本非常大，所以游戏开发具有一定的风险性，但是一些小游戏的开发成本具有成本小、编写简单、易上手的优势，所以这些小游戏的开发也在市场占有一席之地。在这类小游戏中包括换装类，益智类，动作类等等，它以画面精美、操作简单得到大家认可，使人们在休息时间可以得到适当的放松。针对这个情况，我们选择了弹珠传说作为我们的小组课程设计。通过拖动滑块使弹球反弹到墙壁，并提前预判其下落的位置等玩法，从而提高人们的观察能力、反应能力与计算能力。

三、运行环境

本项目的开发环境如下：

操作系统：Windows 10。

开发工具：IntelliJ IDEA JDK17、MySQL 。

开发语言：JAVA语言。

初始化界面调用的音乐类

import java.io.File;
import java.net.URI;public class MUSIC {public void focus(){try{File file=new File("C:\\Users\\Lenovo\\Desktop\\Music\\Jump1.wav");URI uri=file.toURI();System.out.println(uri);AudioInputStream audioIn= AudioSystem.getAudioInputStream(file);Clip clip=AudioSystem.getClip();clip.open(audioIn);clip.start();}catch (Exception e){e.printStackTrace();}}public void defeat(){try{File file=new File("C:\\Users\\Lenovo\\Desktop\\Music\\Defeat1.wav");URI uri=file.toURI();System.out.println(uri);AudioInputStream audioIn= AudioSystem.getAudioInputStream(file);Clip clip=AudioSystem.getClip();clip.open(audioIn);clip.start();}catch (Exception e){e.printStackTrace();}}}

2.单人闯关模式的设计

开始单人闯关前需先注册用户名方便上传到数据库保存成绩，通过键盘事件监听使木板在画板上的坐标移动，小球使通过一帧一帧改变横坐标和纵坐标重绘出来的，使用双缓冲技术实现小球在页面中移动得更丝滑，调用定时器Timer实现关卡自动升级，3000ms为一个关卡，在第三关时会有另一个小球出现。超级模式即是在木板的右边无限延长需要用户来判断哪个时机适合接小球，空格键触发，一共只能用3次。在初始界面点击单人闯关即可进入游戏，当未接到小球时则会结束游戏显示排行榜上的名次，点击右上角即可返回主菜单。

界面展示

代码展示

我们先是跳转到一个输入用户界面的源代码

package JAVA_Lesson_Myprocess;
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;public class Login {public  String username;public void init(){//初始化组件JFrame frame1=new JFrame("弹珠传说");JLabel label_uername=new JLabel("用户名称：");JButton jButton=new JButton("确定");JPanel panel=new JPanel();JTextField jTextField=new JTextField(8);frame1.setResizable(false);//设置不可改变jTextField.setMaximumSize(new Dimension(100,50));frame1.setLayout(new BorderLayout());//设置布局panel.add(label_uername,BorderLayout.WEST);panel.add(jTextField,BorderLayout.CENTER);panel.add(jButton,BorderLayout.SOUTH);frame1.add(panel);jButton.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {username=jTextField.getText();System.out.println(username);try {prinBall p=new prinBall();p.setUsername(username);//这里调用setter方法传参到prinBall界面去p.init();frame1.dispose();} catch (Exception ex) {throw new RuntimeException(ex);}}});frame1.setBounds(500,300,300,100);frame1.setVisible(true);}}

这边我们先说一下双缓冲技术，所谓的双缓冲就是先画一个等比例大小的画布再盖上去这里话不多说直接上代码

private static Image offScreenImage = null;//用于实现双缓冲
//以下在画布中重写public void update(Graphics g) {if(offScreenImage == null) {offScreenImage = this.createImage(TABLE_WIDTH, TABLE_HEIGHT);//创建一张大小和窗口大小一样的虚拟图片}Graphics gOffScreen = offScreenImage.getGraphics();//获得画笔//刷新背景，否则物体运动痕迹会保留Color c = gOffScreen.getColor();gOffScreen.setColor(Color.white);gOffScreen.fillRect(0, 0,TABLE_WIDTH, TABLE_HEIGHT);gOffScreen.setColor(c);paint(gOffScreen);//画到虚拟图片上g.drawImage(offScreenImage, 0, 0, null);//把图片画到屏幕上

这里的update一定要重写，具体的你们可以去看下其他博主写的update与paint的关系，update与paint重写与画布中，每当重绘的时候都要取前景色设置前景色

            Color c = g.getColor();//取出原前景色g.setColor(Color.RED);//设置前景色

然后在你每次绘制完一个图形之后要恢复它

 g.setColor(c);//恢复原前景色

具体可以看下单人闯关整个界面的源代码展示

3.双人合作模式

双人合作模式就和单人闯关一样的原理，只是代码有点长。超级模式也是在木板的右边无限延长需要用户来判断哪个时机适合接小球，核心内容万变不离其宗，我只是添加了两个画布然后两个监听就能实现本地双人游戏的进行，下面就简单展示一下：

在这点进去之前还是有一个需要输入用户名的界面

代码如下：

package JAVA_Lesson_Myprocess;import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;public class Double_Login {public  String username;public void init(){JFrame frame1=new JFrame("弹珠传说");JLabel label_uername=new JLabel("用户名称：");JButton jButton=new JButton("确定");JPanel panel=new JPanel();JTextField jTextField=new JTextField(8);jTextField.setMaximumSize(new Dimension(100,50));frame1.setLayout(new BorderLayout());panel.add(label_uername,BorderLayout.WEST);panel.add(jTextField,BorderLayout.CENTER);panel.add(jButton,BorderLayout.SOUTH);frame1.add(panel);jButton.addActionListener(new ActionListener() {@Overridepublic void actionPerformed(ActionEvent e) {username=jTextField.getText();System.out.println(username);try {Double_People p2=new Double_People();p2.setUsername(username);p2.init();frame1.dispose();} catch (Exception ex) {throw new RuntimeException(ex);}}});// frame1.setLocation(500,300);frame1.setBounds(500,300,300,100);frame1.setResizable(false);frame1.setVisible(true);}}

下面是双人合作的界面及源代码：

4.数据库连接与操作

在这成绩上传到数据库之前记得要设置好数据库，由于单人闯关模式和双人合作模式在结束时都会显示排名，因此我们需要新建一个类来调用它的方法遍历数据库的内容再对成绩排序，然后遍历每个数组找到相符合的用户名再返回相关排名，一般情况下我们是放到一个二维数组里面去的

接下来就是代码展示

//查询所有的数据，先遍历一共有几行int line=0;while (rs.next()) {line++;}rs.close();rs = stat.executeQuery(sql);//清空之后回到原点先将数据存储在数组中Object[][] data = new Object[line][];for (int i = 0; rs.next(); i++) {// number = i + 1;data[i] = new Object[]{0, rs.getString("username"), rs.getInt("mark"),};}rs.close();Arrays.sort(data, new Comparator<Object[]>() {@Overridepublic int compare(Object[] o1, Object[] o2) {return (Integer) o2[2]-(Integer)o1[2];}});//定义一个二维数组的比较器 降序排序for (int i = 0; i < line; i++) {data[i][0]=i+1;}//重新给它排名赋值for (int i = 0; i < line; i++) {if (user.equals(data[i][1])){return (Integer) data[i][0];//查询相符合的用户名称就返回}}return 0;}public int run (String user) throws Exception {String url = "jdbc:mysql://localhost:3306/ceshi";String username = "root";String password = "123456";Class.forName("com.mysql.cj.jdbc.Driver");JFrame frame = new JFrame("排行榜");JPanel panel = new JPanel();JLabel label_1 = new JLabel("单人闯关排行榜");JLabel label_2 = new JLabel("双人合作排行榜");Object[] titles = {"排名", "用户名", "成绩"};Connection conn = DriverManager.getConnection(url, username, password);String sql = "SELECT * FROM mark_table";Statement stat = conn.createStatement();int line = 0, number;number = 0;conn = DriverManager.getConnection(url, username, password);ResultSet rs = stat.executeQuery(sql);sql = "SELECT * FROM Double_people";stat = conn.createStatement();rs = stat.executeQuery(sql);// ResultSet rs_2=stat.executeQuery(sql);line = 0;while (rs.next()) {line++;}System.out.println(line);rs.close();rs = stat.executeQuery(sql);Object[][] data_2 = new Object[line][];for (int i = 0; rs.next(); i++) {// number = i + 1;data_2[i] = new Object[]{0, rs.getString("username"), rs.getInt("mark"),};}rs.close();Arrays.sort(data_2, new Comparator<Object[]>() {@Overridepublic int compare(Object[] o1, Object[] o2) {return (Integer) o2[2]-(Integer)o1[2];}});for (int i = 0; i < line; i++) {data_2[i][0]=i+1;}for (int i = 0; i < line; i++) {if (user.equals(data_2[i][1])){return (Integer) data_2[i][0];}}return 0;}
}

5.数据库连接，排行榜

五、总结

把每份代码都复制下来放到同一个包里面，改改数据库连接，音乐文件路径，就能运行。通过本次的课设实践使我更加认识java的实用性，本次使用的版本为JDK17。从界面的绘画、音效素材的寻找与设置、游戏关卡设置、数据库连接，让我更加对一整个游戏体系有了不一样的认识，再者每当我调试自己亲手做的游戏时都会有一种喜悦的心情，我体会到了作为开发者的乐趣。一开始我是使用AWT来绘画的，但是由于画面太过于闪烁于是我找遍各种论坛，经过一下午的学习我了解到了计算机图形基础—双缓存原理。从概念到实践我终于在程序中使用了双缓冲的技术，这是我在本次开发以来最为开心的一件事。游戏音效则是通过RPG Maker MZ一个RPG 的游戏引擎的音效素材库来寻找的，通过事件监听，来使小球碰撞发出声音，给用户一种身临其境的感受。每当用户接不到小球结束时我们设置的是victory的音效，因为在我们看来每个人都是成功的，我们选择音效时都有不同的含义。数据库连接则是通过JTable来实现的，通过一个二维数组和我们对二维数组进行排列来使得内容呈降序呈现，再放入到JTable中。还有就是JFrame的布局，我们采用最多的就是流体式布局和绝对布局，再这布局中我们了解到了每一个组件。
