Java 课程设计：基于 Swing 的蜘蛛接龙游戏（附源代码） - III，核心代码

启动类构造方法

    public Spider(){
        //改变系统默认字体
        Font font = new Font("Dialog", Font.PLAIN, 12);
        java.util.Enumeration keys = UIManager.getDefaults().keys();
        while (keys.hasMoreElements()) {
            Object key = keys.nextElement();
            Object value = UIManager.get(key);
            if (value instanceof javax.swing.plaf.FontUIResource) {
                UIManager.put(key, font);
            }
        }
        setTitle("蜘蛛牌");
        setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
        //设置框架的大小
        setSize(1024, 742);

        //生成SpiderMenuBar对象，并放置在框架之上
        setJMenuBar(new SpiderMenuBar(this));
        pane = this.getContentPane();
        //设置背景颜色
        pane.setBackground(new Color(0, 112, 26));
        //将布局管理器设置成为null
        pane.setLayout(null);
        clickLabel = new JLabel();
        clickLabel.setBounds(883, 606, 121, 96);
        pane.add(clickLabel);

        clickLabel.addMouseListener(new MouseAdapter(){
            public void mouseReleased(MouseEvent me){
                if (c < 60){
                    Spider.this.deal();
                }
            }
        });

        this.initCards();
        this.randomCards();
        this.setCardsLocation();
        groundLabel = new JLabel[10];

        int x = 20;
        for (int i = 0; i < 10; i++)
        {
            groundLabel[i] = new JLabel();
            groundLabel[i]
                    .setBorder(javax.swing.BorderFactory
                            .createEtchedBorder(javax.swing.border.EtchedBorder.RAISED));
            groundLabel[i].setBounds(x, 25, 71, 96);
            x += 101;
            this.pane.add(groundLabel[i]);
        }

        this.setVisible(true);
        this.deal();

        this.addKeyListener(new KeyAdapter(){
            class Show extends Thread{
                public void run(){
                    Spider.this.showEnableOperator();
                }
            }

            public void keyPressed(KeyEvent e){
                if (finish != 8) if (e.getKeyCode() == KeyEvent.VK_D && c < 60){
                    Spider.this.deal();
                }
                else if (e.getKeyCode() == KeyEvent.VK_M){
                    new Show().start();
                }
            }
        });
    }

纸牌初始化

public void initCards(){
        //如果纸牌已被赋值，即将其从框架的面板中移去
        if (cards[0] != null){
            for (int i = 0; i < 104; i++){
                pane.remove(cards[i]);
            }
        }

        int n = 0;
        //通过难度等级，为n赋值
        if (this.grade == Spider.EASY){
            n = 1;
        }
        else if (this.grade == Spider.NATURAL){
            n = 2;
        }
        else{
            n = 4;
        }
        //为card赋值
        for (int i = 1; i <= 8; i++){
            for (int j = 1; j <= 13; j++){
                cards[(i - 1) * 13 + j - 1] = new PKCard((i % n + 1) + "-" + j,
                        this);
            }
        }

        //随机纸牌初始化
        this.randomCards();
    }

纸牌随机化

    public void randomCards(){
        PKCard temp = null;
        //随机生成牌号
        for (int i = 0; i < 52; i++){
            int a = (int) (Math.random() * 104);
            int b = (int) (Math.random() * 104);
            temp = cards[a];
            cards[a] = cards[b];
            cards[b] = temp;
        }
    }

设置纸牌位置

public void setCardsLocation(){
        table = new Hashtable();
        c = 0;
        finish = 0;
        n = 0;
        a = 0;
        int x = 883;
        int y = 580;
        //初始化待展开的纸牌
        for (int i = 0; i < 6; i++){
            for (int j = 0; j < 10; j++){
                int n = i * 10 + j;
                pane.add(cards[n]);
                //将card转向背面
                cards[n].turnRear();
                //将card放在固定的位置上
                cards[n].moveto(new Point(x, y));
                //将card的位置及相关信息存入
                table.put(new Point(x, y), cards[n]);
            }
            x += 10;
        }

        x = 20;
        y = 45;
        //初始化表面显示的纸牌
        for (int i = 10; i > 5; i--){
            for (int j = 0; j < 10; j++){
                int n = i * 10 + j;
                if (n >= 104) continue;
                pane.add(cards[n]);
                cards[n].turnRear();
                cards[n].moveto(new Point(x, y));
                table.put(new Point(x, y), cards[n]);
                x += 101;
            }
            x = 20;
            y -= 5;
        }
    }
