贪吃蛇完整代码----GUI

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
在这里插入图片描述

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;}@Overrideprotected 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);}}@Overridepublic 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";}}@Overridepublic 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();}@Overridepublic void keyTyped(KeyEvent e) {}@Overridepublic void keyReleased(KeyEvent e) {}}
