Question

在我的游戏中，玩家的手牌通常约为5张牌（以及单独的ArrayList），但在游戏中可以通过很多“抽奖牌”选项快速获得大量牌。在显示卡片的其他任何地方，我将它们放在JLabel中更新以显示图像，当点击时，图像移动到播放器丢弃堆并且卡被添加到丢弃ArrayList，就像这样：

private void mainDeckMouseClicked(java.awt.event.MouseEvent evt) {                                      
        ImageIcon mainDeckEmpty = new ImageIcon("C:\\DC Card Game\\src\\DCCardGame\\resources\\Other Cards\\Empty Main Deck.png");

        if (DrawCards.cards.isEmpty())
            mainDeck.setIcon(mainDeckEmpty);

        if (slot1Card == noCard)
        {
            if (!DrawCards.cards.isEmpty())
            {
                slot1Card = DrawCards.drawFromMainDeck();
                lineupSlot1.setIcon(new ImageIcon(slot1Card.getImage()));
                lineupSlot1.setToolTipText(slot1Card.getCardText());
                if (DrawCards.cards.isEmpty())
                mainDeck.setIcon(mainDeckEmpty);
            }
        }
}

这是一个代码片段，从单击主甲板时开始，它将卡片添加到阵容中。这很好用。

我遇到的问题是，对于playerHand ArrayList，我无法弄清楚如何动态添加JLabel（必要时），指定基于绘制的卡将图像映射到它，然后将实际的卡对象分配给可以操作的变量。在上面的例子中，我将它分配给预定义的变量slot1Card，所以当我无法在运行时定义卡时，如何将卡分配给变量或者是否有办法分配所有变量上面显示的值（丢弃图像，播放器手形图像，工具提示文本，卡片对象等）而不使用变量？另外，我在GridLayout内使用JScrollPane在面板中显示玩家手牌。

提前致谢！

编辑：更多SSCCE - 这是我刚刚编写的代码，因此在鼠标点击它会将卡片从卡片添加到玩家手中。我相信这需要修改为向jpanel添加标签的内容。

private void playerDeckMouseClicked(java.awt.event.MouseEvent evt) {                                        
    ImageIcon playerDeckEmpty = new ImageIcon("C:\\DC Card       Game\\src\\DCCardGame\\resources\\Other Cards\\Empty Player Deck.png");

    if (DrawCards.player_1_deck.isEmpty())
        playerDeck.setIcon(playerDeckEmpty);

    if (!DrawCards.cards.isEmpty())
        {
            playerHandSlot1Card = DrawCards.drawFromPlayerDeck();
            playerHandSlot1.setIcon(new ImageIcon(playerHandSlot1Card.getImage()));
            playerHandSlot1.setToolTipText(playerHandSlot1Card.getCardText());

            playerHandSlot2Card = DrawCards.drawFromPlayerDeck();
            playerHandSlot2.setIcon(new ImageIcon(playerHandSlot2Card.getImage()));
            playerHandSlot2.setToolTipText(playerHandSlot2Card.getCardText());

            playerHandSlot3Card = DrawCards.drawFromPlayerDeck();
            playerHandSlot3.setIcon(new ImageIcon(playerHandSlot3Card.getImage()));
            playerHandSlot3.setToolTipText(playerHandSlot3Card.getCardText());

            playerHandSlot4Card = DrawCards.drawFromPlayerDeck();
            playerHandSlot4.setIcon(new ImageIcon(playerHandSlot4Card.getImage())); 
            playerHandSlot4.setToolTipText(playerHandSlot4Card.getCardText());

            playerHandSlot5Card = DrawCards.drawFromPlayerDeck();
            playerHandSlot5.setIcon(new ImageIcon(playerHandSlot5Card.getImage()));
            playerHandSlot5.setToolTipText(playerHandSlot5Card.getCardText());
        }
    if (DrawCards.player_1_deck.isEmpty())
        playerDeck.setIcon(playerDeckEmpty);
}

不是为每个玩家的牌创建单独的变量，而是使用List，例如ArrayList。您可以根据需要创建列表的每个元素，如下所示：

private void playerDeckMouseClicked(java.awt.event.MouseEvent evt) {                                        
    ImageIcon playerDeckEmpty = new ImageIcon("C:\\DC Card       Game\\src\\DCCardGame\\resources\\Other Cards\\Empty Player Deck.png");

    if (DrawCards.player_1_deck.isEmpty())
        playerDeck.setIcon(playerDeckEmpty);

    for (int i = 0; i < 5 && !DrawCards.cards.isEmpty(); i++)
    {
            playerHandSlotCard = DrawCards.drawFromPlayerDeck();
            playerHandSlot.setIcon(new ImageIcon(playerHandSlot1Card.getImage()));
            playerHandSlot.setToolTipText(playerHandSlot1Card.getCardText());
            playerHandList.add(platerHandSlot);
    }
    if (DrawCards.player_1_deck.isEmpty())
        playerDeck.setIcon(playerDeckEmpty);
}

要显示玩家手中包含的许多标签，您可以将其动态添加到容器中。不是使用JLabel来显示玩家的手，而是使用JPanel和CardLayout。每当玩家抽一张牌时，请拨打panel.add(playerHandSlot)。如果这种情况发生在playerDeckMouseClicked方法之外，您可以使用for循环来访问playerHandList

的元素

for(JLabel playerHandSlot : playerHandList) {
    panel.add(playerHandSlot);
}

制作纸牌游戏时，需要根据玩家手中的牌数在运行时将JLabel添加到JPanel
