小狗踢足球

马里奥是左哥教我们做的线程游戏，让我们认识线程游戏的做法，处理游戏中的元素，和一系列的原理，让我们从程序的角度去理解游戏。

然后让我们自己去做一个线程游戏出来，我自己做的游戏是小狗踢足球。

马里奥的代码我就不发了，发我自己做的小狗踢足球。

package 足球小狗;import java.awt.Graphics;import java.awt.Image;import java.awt.event.KeyAdapter;import java.awt.event.KeyEvent;import java.awt.image.BufferedImage;import java.util.ArrayList;import javax.swing.Icon;import javax.swing.ImageIcon;import javax.swing.JLabel;import javax.swing.JPanel;public class GamePanel extends JPanel{public ImageIcon image = new ImageIcon("image/Dog.png");public FootBall footBall;public Ball ball;public BlackDog blackDog;public WhiteDog whiteDog;public static ArrayList<BlackDog> list = new ArrayList<BlackDog>();public boolean flagReady = true;public ImageIcon ready = new ImageIcon("runimages/READY.png");public boolean flag = true;public ImageIcon icon = new ImageIcon("image/开始界面.png");public GamePanel(FootBall footBall){ball = new Ball();whiteDog = new WhiteDog(this,ball);blackDog = new BlackDog(this,ball,whiteDog);blackDog.start();whiteDog.start();this.footBall = footBall;initPanel();}public void initPanel(){KeyAdapter blackka = new KeyAdapter(){public void keyPressed(KeyEvent e) {int code = e.getKeyCode();if(code == 68){blackDog.right = true ;}else if(code == 65){blackDog.left = true;}else if(code == 87){blackDog.up = true;}else if(code == 83){blackDog.down = true;}if(code == 39){whiteDog.right = true ;}else if(code == 37){whiteDog.left = true;}else if(code == 38){whiteDog.up = true;}else if(code == 40){whiteDog.down = true;}} public void keyReleased(KeyEvent e) {int code = e.getKeyCode();if(code == 68){blackDog.right = false ;}else if(code == 65){blackDog.left = false;}else if(code == 87){blackDog.up = false;}else if(code == 83){blackDog.down = false;}if(code == 39){whiteDog.right = false ;}else if(code == 37){whiteDog.left = false;}else if(code == 38){whiteDog.up = false;}else if(code == 40){whiteDog.down = false;}}};footBall.addKeyListener(blackka);}public void paint(Graphics g) {BufferedImage bi = (BufferedImage)createImage(this.getWidth(),this.getHeight());Graphics graphics = bi.getGraphics();graphics.drawImage(image.getImage(), 0, 0, null);graphics.drawImage(ball.getImage().getImage(), ball.getX(), ball.getY(), null);graphics.drawImage(blackDog.getBlackDog(), blackDog.getX(), blackDog.getY(), null);graphics.drawImage(whiteDog.getWhiteDog(), whiteDog.getX(), whiteDog.getY(), null);g.drawImage(bi, 0, 0, null);}}

这是游戏面板类

下面是黑狗类，白狗类和黑狗类差不多，就不发了。

然后在窗口的地方用卡片布局来切换面板，让游戏更多乐趣

package 足球小狗;import java.awt.CardLayout;import java.awt.event.MouseAdapter;import java.awt.event.MouseEvent;import javax.swing.JFrame;public class FootBall extends JFrame{public CardLayout cl;public static void main(String[] args) {FootBall fb = new FootBall();fb.initFrame();}public void initFrame(){setTitle("C罗Dog Vs 贝克Dog");setSize(735,520);cl = new CardLayout();this.setLayout(cl);setLocationRelativeTo(null);setDefaultCloseOperation(3);//添加开始面板StartFrame sf = new StartFrame();this.getContentPane().add(sf);//添加游戏面板GamePanel gp = new GamePanel(this);this.getContentPane().add(gp);setVisible(true);MouseAdapter ma = new MouseAdapter() {public void mouseClicked(MouseEvent e) {cl.last(FootBall.this.getContentPane());gp.setFocusable(false);sf.setFocusable(false);FootBall.this.setFocusable(true);}};this.addMouseListener(ma);}}

这就是我这几天做的小狗踢足球。
