Java如何实现接月饼小游戏

这篇文章给大家分享的是有关Java如何实现接月饼小游戏的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

主要设计

• 设计游戏界面，用swing实现

• 设计背景

• 设计得分物体-月饼，碰到加一分

• 设计障碍物-月亮，碰到会死亡

• 监听鼠标的左右键，用来控制篮子左右移动

• 设计积分系统

• 将resource文件夹设为resource（Project Manage中可以设置），因为要用里面的图片

游戏开始界面：

代码实现

游戏启动类

public class Start {    public static void main(String[] args) throws URISyntaxException {        new EatGame();    }}

核心类

public class EatGame extends JFrame implements ActionListener, MouseListener{    private final int WIDTH = 400;    private final int HEIGHT = 800;    private int score;    private int ticks;     private boolean gameOver = false;    private GameControl control;     private List moons;    private List cakes;    private Timer timer;    private ChangeE changeE;    /**     * Constructor for objects of class FallingGame     */    public EatGame() throws URISyntaxException {        changeE = new ChangeE(150, 650, "player.jpg", WIDTH);        moons = new ArrayList<>();        cakes = new ArrayList<>();        addMoonAndCake();                control = new GameControl(changeE, moons, cakes);        timer = new Timer(20, this);                 //add keybinds        control.addAction("Left", -20, KeyEvent.VK_LEFT);        control.addAction("Right", 20, KeyEvent.VK_RIGHT);                //add components        add(control);        addMouseListener(this);        control.addMouseListener(this);        setTitle("吃月饼");        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);        setSize(WIDTH, HEIGHT);        setResizable(false);        setVisible(true);               timer.start();    }    /**     * 添加月亮和月饼     */    public void addMoonAndCake() {        Random r = new Random();        int x, y;        x = 60 + (r.nextInt(35) * 2);        y = r.nextInt(20) + moons.size() * 30;        Moon moon1 = new Moon(x, y, "moon.png");        moons.add(moon1);        x = 190 + r.nextInt(35) * 2;        y = r.nextInt(20) + moons.size() * 30;        Moon moon2 = new Moon(x, y, "moon.png");        moons.add(moon2);        x = 80 + (r.nextInt(35) * 2);        y = r.nextInt(20) + moons.size() * 50;        Cake cake = new Cake(x, y, "cake.png");        cakes.add(cake);    }    /**     * 更新窗口     */    private void updateFrame() {        ticks++;        for(int i = 0; i < moons.size(); i++)        {            Moon moon = moons.get(i);            if(ticks % 25 == 0 && moon.getSpeed() < 10)            {                moon.setSpeed(moon.getSpeed() + 2);            }        }        Iterator moonIterator = moons.iterator();        while (moonIterator.hasNext()) {            Moon moon = moonIterator.next();            // 超出屏幕            if(moon.getY() > HEIGHT) {                moonIterator.remove();            } else                moon.move();        }        Iterator cakeIterator = cakes.iterator();        while (cakeIterator.hasNext()) {            Cake cake = cakeIterator.next();            // 超出屏幕            if(cake.getY() > HEIGHT) {                cakeIterator.remove();            } else                cake.move();        }        if(moons.size() == 0) {            addMoonAndCake();        }    }    private boolean checkCollision() {        Rectangle rectangle = (Rectangle) changeE.getShape();        for(Moon moon : moons) {            Ellipse2D circle = (Ellipse2D) moon.getShape();            // 判断是否与圆形相撞            if (circle.intersects(rectangle)) {                gameOver = true;            }        }        Iterator cakeIterator = cakes.iterator();        while (cakeIterator.hasNext()) {            Cake cake = cakeIterator.next();            Ellipse2D circle = (Ellipse2D) cake.getShape();            if (circle.intersects(rectangle)) {                score ++;   // 得分                cakeIterator.remove();            }        }        return gameOver;    }    public void actionPerformed(ActionEvent e)    {        if(gameOver) {            timer.stop();             control.drawEnd(control.getGraphics(), score);        } else {            //continue with game            updateFrame();            checkCollision();            control.repaint();         }    }    public void mouseClicked(MouseEvent e) {    }    public void mousePressed(MouseEvent e)    {        if(gameOver)        {            //reset game            moons.clear();            control.removeAll();             control.updateUI();             score = 0;            changeE.setX(150);            changeE.setY(650);            addMoonAndCake();            timer.start();            repaint();            gameOver = false;         }    }    public void mouseReleased(MouseEvent e)    {            }    public void mouseEntered(MouseEvent e)    {            }    public void mouseExited(MouseEvent e)    {            }}
