java swing开发贪吃蛇游戏javaweixin43824233的博客-

本篇是根据视频学习完成的，视频和静态资源在最末尾。
所以我就直接放代码了，详细过程看视频。
项目结构

Data.java

package snake; import java.net.*; import javax.swing.*; //存放外部数据 public class Data { //头部的图片 URL：定位图片的地址 ImageIcon：图片 public static URL headerURL = Data.class.getResource("/statics/header.png"); public static ImageIcon header = new ImageIcon(headerURL); public static URL upURL = Data.class.getResource("/statics/up.png"); public static URL downURL = Data.class.getResource("/statics/down.png"); public static URL leftURL = Data.class.getResource("/statics/left.png"); public static URL rightURL = Data.class.getResource("/statics/right.png"); public static ImageIcon up = new ImageIcon(upURL); public static ImageIcon down = new ImageIcon(downURL); public static ImageIcon left = new ImageIcon(leftURL); public static ImageIcon right = new ImageIcon(rightURL); public static URL bodyURL = Data.class.getResource("/statics/body.png"); public static ImageIcon body = new ImageIcon(bodyURL); public static URL foodURL = Data.class.getResource("/statics/food.png"); public static ImageIcon food = new ImageIcon(foodURL); } 

GamePanel.java

package snake; import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.KeyEvent; import java.awt.event.KeyListener; import java.util.Random; public class GamePanel extends JPanel implements KeyListener, ActionListener{ int lenth;//长度 int[] snakeX = new int[600]; int[] snakeY = new int[500];  String fx;//RLUD左右上下  Boolean isStart = false;//游戏开始没有  Timer timer = new Timer(100,this); //定义一个食物 int foodx; int foody;  Random random = new Random(); //死亡判断 boolean isFail = false; //积分系统 int score; //构造器 public GamePanel() { init(); //获取键盘的监听事件 this.setFocusable(true); this.addKeyListener(this);   timer.start();//让时间动起来 } //初始化 public void init() {   lenth = 3;   snakeX[0] =100;snakeY[0] = 100;   snakeX[1] =75;snakeY[1] = 100;   snakeX[2] =50;snakeY[2] = 100;   fx = "R";      foodx = 25+25*random.nextInt(34);   foody = 75+25*random.nextInt(24);      score = 0; } //画板 ：画界面，画蛇 @Override protected void paintComponent(Graphics g) { super.paintComponent(g);//清屏 this.setBackground(Color.WHITE);//背景颜色 //绘制头部的广告栏   Data.header.paintIcon(this, g, 25, 11); //绘制游戏区域   g.fillRect(25, 75, 850, 600); //画蛇 if(fx.equals("R")) {    Data.right.paintIcon(this,g, snakeX[0], snakeY[0]); } else if(fx.equals("L")) {    Data.left.paintIcon(this,g, snakeX[0], snakeY[0]); } else if(fx.equals("U")) {    Data.up.paintIcon(this,g, snakeX[0], snakeY[0]); } else if(fx.equals("D")) {    Data.down.paintIcon(this,g, snakeX[0], snakeY[0]); } for(int i=1;i<lenth;i++) {    Data.body.paintIcon(this,g, snakeX[i], snakeY[i]);//蛇的身体长度通过lenth控制 } //画积分   g.setColor(Color.WHITE);   g.setFont(new Font("微软雅黑",Font.BOLD,18));   g.drawString("长度："+lenth, 750, 35);   g.drawString("分数："+score, 750, 50); //画食物   Data.food.paintIcon(this, g, foodx, foody); //游戏提示，是否开始 if(isStart == false) { //画一个文字    g.setColor(Color.white);    g.setFont(new Font("微软雅黑",Font.BOLD,40));//设置字体    g.drawString("按下空格开始游戏", 300, 300); } //失败提醒 if(isFail) { //画一个文字    g.setColor(Color.RED);    g.setFont(new Font("微软雅黑",Font.BOLD,40));//设置字体    g.drawString("游戏失败,按下空格重新开始游戏", 200, 300); } } //接受键盘的输入:监听 @Override public void keyTyped(KeyEvent e) { // TODO Auto-generated method stub //键盘按下，弹起 } @Override public void keyPressed(KeyEvent e) { // TODO Auto-generated method stub //键盘按下，未释放 //获取按下的键盘是哪个键 int keyCode = e.getKeyCode(); if(keyCode == KeyEvent.VK_SPACE) { if(isFail)//失败，游戏再来一次 {     isFail = false; init();//初始化游戏 } else//暂停游戏 {     isStart = !isStart; } repaint();//刷新界面 } //键盘控制走向 if (keyCode==KeyEvent.VK_UP) {             fx="U"; }else if (keyCode==KeyEvent.VK_DOWN) {             fx="D"; }else if (keyCode==KeyEvent.VK_LEFT) {             fx="L"; }else if (keyCode==KeyEvent.VK_RIGHT) {             fx="R"; } } @Override public void keyReleased(KeyEvent e) { // TODO Auto-generated method stub //释放某个键 } //定时器：监听事件，帧 @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub //如果游戏处于开始转态，并且游戏没有结束 if(isStart && isFail==false) { for(int i=lenth-1;i>0;i--)//除了脑袋身体都往前移动 {     snakeX[i] = snakeX[i-1];     snakeY[i] = snakeY[i-1]; } //通过控制方向让头部移动 if(fx.equals("R")) {                 snakeX[0]=snakeX[0]+25; if(snakeX[0]>850){ snakeX[0]=25; } }else if (fx.equals("L")) {                 snakeX[0]=snakeX[0]-25; if(snakeX[0]<25){ snakeX[0]=850; } }else if (fx.equals("U")) {                 snakeY[0]=snakeY[0]-25; if(snakeY[0]<75){ snakeY[0]=650; } }else if (fx.equals("D")) {                 snakeY[0]=snakeY[0]+25; if(snakeY[0]>650){ snakeY[0]=75; } } //如果小蛇的头和food坐标重合 if(snakeX[0] == foodx && snakeY[0]==foody) {     lenth++;     score += 10; //重新生成food     foodx = 25+25*random.nextInt(34);     foody = 75+25*random.nextInt(24); } //结束panduan for(int i=1;i<lenth;i++) { if(snakeX[0]==snakeX[i] && snakeY[0]==snakeY[i])      isFail = true; } repaint(); }   timer.start();//让时间动起来 } } 

StartGames.java

package snake; import javax.swing.*; public class StartGames { public static void main(String[] args) { // TODO Auto-generated method stub //绘制一个静态窗口 JFrame   JFrame frame = new JFrame("贪吃蛇");   frame.setBounds(10,10,900,720);//设置界面大小   frame.setResizable(false);   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//让游戏能够关闭 //面板Jpanel  可以加入到JFrame   frame.add(new GamePanel());      frame.setVisible(true);//让窗口可以显示出来 } } 

代码好了，接下来是静态资源:
