java使用GUI实现贪吃蛇游戏
本文实例为大家分享了java使用GUI实现贪吃蛇游戏的具体代码,供大家参考,具体内容如下
整个代码分为三部分
1.游戏开始界面
2.data基本图片的添加
3.面板,将小蛇画到面板上
这是游戏完整界面
1. 游戏开始界面
public class StartGame { public static void main(String[] args) { JFrame frame = new JFrame(); frame.setBounds(10,10,900,720); frame.setResizable(false); frame.add(new GamePanel()); frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE); frame.setVisible(true); } }
2.data数据
public class Data { private static URL headerURL=Data.class.getResource("statics/header.png"); public static ImageIcon header=new ImageIcon(headerURL); private static URL upURL=Data.class.getResource("statics/up.png"); private static URL downURL=Data.class.getResource("statics/down.png"); private static URL leftURL=Data.class.getResource("statics/left.png"); private 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); private static URL bodyURL=Data.class.getResource("statics/body.png"); public static ImageIcon body=new ImageIcon(bodyURL); private static URL foodURL=Data.class.getResource("statics/food.png"); public static ImageIcon food=new ImageIcon(foodURL); }
3.面板绘制
public class GamePanel extends JPanel implements KeyListener, ActionListener { int length; int [] snakeX=new int[600]; int [] snakeY=new int[500]; String fx; int foodx; int foody; Random random=new Random(); int score; boolean isStart=false; boolean isFail=false; Timer timer=new Timer(75,this); public GamePanel() { init(); this.setFocusable(true); this.addKeyListener(this); timer.start(); } public void init(){ length=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; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); this.setBackground(Color.WHITE); Data.header.paintIcon(this,g,25,11); g.fillRect(25,75,850,600); g.setColor(Color.white); g.setFont(new Font("微软雅黑",Font.BOLD,18)); g.drawString("长度"+length,750,30); g.drawString("分数"+score,750,50); Data.food.paintIcon(this,g,foodx,foody); 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]); } //Data.right.paintIcon(this,g,snakeX[0],snakeY[0]); for (int i = 1; i < length; i++) { Data.body.paintIcon(this,g,snakeX[i],snakeY[i]); } if(isStart==false){ g.setColor(Color.white); g.setFont(new Font("宋体",Font.BOLD,40)); g.drawString("想玩就嗯空格",300,300); } if(isFail){ g.setColor(Color.red); g.setFont(new Font("微软雅黑",Font.BOLD,40)); g.drawString("人生不能重来,请走好每一步",150,350); } } @Override public void keyPressed(KeyEvent e) { int keyCode = e.getKeyCode(); if(keyCode == KeyEvent.VK_SPACE){ if(isFail){ isFail=false; init(); }else{ isStart=!isStart; } repaint(); } 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 actionPerformed(ActionEvent e) { if(isStart&&isFail==false){ if(foodx==snakeX[0]&&foody==snakeY[0]){ length++; score+=10; foodx=25+25*random.nextInt(34); foody=75+25*random.nextInt(24); } for (int i = length-1; i >0 ; i--) { snakeX[i]=snakeX[i-1]; snakeY[i]=snakeY[i-1]; } 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;} } for (int i = 1; i < length; i++) { if(snakeY[0]==snakeY[i]&&snakeX[0]==snakeX[i]){ isFail=true; } } repaint(); } timer.start(); } @Override public void keyTyped(KeyEvent e) { } @Override public void keyReleased(KeyEvent e) { } }
小蛇的各个部位参数如下
