1、精选优质文档-倾情为你奉上Java贪吃蛇源代码 import java.awt.*; import java.awt.event.*; public class GreedSnake /主类 /* * param args */ public static void main(String args) / TODO Auto-generated method stub new MyWindow(); class MyPanel extends Panel implements KeyListener,Runnable/自定义面板类，继承了键盘和线程接口 Button snake; /定义蛇按钮

2、 int shu=0; /蛇的节数 int food; /食物数组 boolean result=true; /判定结果是输 还是赢 Thread thread; /定义线程 static int weix,weiy; /食物位置 boolean t=true; /判定游戏是否结束 int fangxiang=0; /蛇移动方向 int x=0,y=0; /蛇头位置 MyPanel() setLayout(null); snake=new Button20; food=new int 20; thread=new Thread(this); for(int j=0;j20;j+) foodj=

3、(int)(Math.random()*99);/定义20个随机食物 weix=(int)(food0*0.1)*60; /十位*60为横坐标 weiy=(int)(food0%10)*40; /个位*40为纵坐标 for(int i=0;i1)/判断是否咬自己的尾巴 if(snakenum1.getBounds().x=snake0.getBounds().x&snakenum1.getBounds().y=snake0.getBounds().y) t=false; result=false; repaint(); num1-; if(x=this.getWidth()|y=this.ge

4、tHeight()/判断是否撞墙 t=false; result=false; repaint(); int num=shu; while(num0) /设置蛇节位置 snakenum.setBounds(snakenum-1.getBounds(); num-; if(shu=15) /如果蛇节数等于15则胜利 t=false; result=true; repaint(); public void keyPressed(KeyEvent e) /按下键盘方向键 if(e.getKeyCode()=KeyEvent.VK_RIGHT)/右键 if(fangxiang!=1)/如果先前方向不为

5、左 fangxiang=0; else if(e.getKeyCode()=KeyEvent.VK_LEFT) if(fangxiang!=0) fangxiang=1; else if(e.getKeyCode()=KeyEvent.VK_UP) if(fangxiang!=3) fangxiang=2; else if(e.getKeyCode()=KeyEvent.VK_DOWN) if(fangxiang!=2) fangxiang=3; public void keyTyped(KeyEvent e) public void keyReleased(KeyEvent e) publi

6、c void paint(Graphics g) /在面板上绘图 int x1=this.getWidth()-1; int y1=this.getHeight()-1; g.setColor(Color.red); g.fillOval(weix, weiy, 10, 10);/食物 g.drawRect(0, 0, x1, y1); /墙 if(t=false&result=false) g.drawString(GAME OVER!, 250, 200);/输出游戏失败 else if(t=false&result=true) g.drawString(YOU WIN!, 250, 20

7、0);/输出游戏成功 class MyWindow extends Frame implements ActionListener/自定义窗口类 MyPanel my; Button btn; Panel panel; MyWindow() super(GreedSnake); my=new MyPanel(); btn=new Button(begin); panel=new Panel(); btn.addActionListener(this); panel.add(new Label(begin后请按Tab键选定蛇); panel.add(btn); panel.add(new Lab

8、el(按上下左右键控制蛇行动); add(panel,BorderLayout.NORTH); add(my,BorderLayout.CENTER); setBounds(100,100,610,500); setVisible(true); validate(); addWindowListener(new WindowAdapter() public void windowClosing(WindowEvent e) System.exit(0); ); public void actionPerformed(ActionEvent e)/按下begin按钮 if(e.getSource()=btn) try my.thread.start(); /开始线程 my.validate(); catch(Exception ee) /文件名保存为：GreedSnake.java专心-专注-专业
