JAVA代码flappy Bird(飞翔的小鸟)附图

1、package flappyBrid01;import java.awt.Color;import java.awt.Font;import java.awt.Graphics;import java.awt.Graphics2D;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;import java.awt.event.MouseListener;import java.awt.image.BufferedImage;import javax.imageio.ImageIO;import javax.sw

2、ing.JFrame;import javax.swing.JPanel;public class BirdGame extends JPanel Bird bird;Column column1, column2;Ground ground;BufferedImage backGround;/ 分数int score;/ 标志游戏是否结束/ boolean gameOver;BufferedImage gameOverImage;BufferedImage startImage;/ 游戏状态int state;public static final int START = 0;/ 常量名字大

3、写public static final int RUNNING = 1;public static final int GAMEOVER = 2;public BirdGame() throws Exception score = 0;bird = new Bird();column1 = new Column(1);column2 = new Column(2);ground = new Ground();backGround = ImageIO.read(getClass().getResource(bg.png);/ gameOver = false;state = START;gam

4、eOverImage = ImageIO.read(getClass().getResource(gameover.png);startImage = ImageIO.read(getClass().getResource(start.png);/ 游戏启动方法public static void main(String args) throws Exception JFrame frame = new JFrame(Flappy Bird);BirdGame game = new BirdGame();frame.add(game);frame.setSize(432, 644);frame

5、.setLocationRelativeTo(null);frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);frame.setVisible(true);game.action();/ 画图Override/认定是重写，下面有错就会指出public void paint(Graphics g) g.drawImage(backGround, 0, 0, null);g.drawImage(column1.image, column1.x - column1.width / 2, column1.y- column1.height / 2,

6、 null);g.drawImage(column2.image, column2.x - column2.width / 2, column2.y- column2.height / 2, null);g.drawImage(ground.image, ground.x, ground.y, null);/ 鸟的旋转放在鸟的前面Graphics2D g2 = (Graphics2D) g;/ 强转g2.rotate(-bird.alpha, bird.x, bird.y);/ （角度，中心点的x，中心点的一）g.drawImage(bird.image, bird.x - bird.widt

9、结束，所有游戏内容重置bird = new Bird();column1 = new Column(1);column2 = new Column(2);ground = new Ground();score = 0;/ 改变状态state = START;break;case START:state = RUNNING;case RUNNING:/ 鸟向上飞bird.fly(); catch (Exception e1) e1.printStackTrace();this.addMouseListener(l);while (true) /* * if (!gameOver) ground.
