我正在用 Java 创建一个 BlackJack 游戏,并在创建它时尝试使用 MVC 设计。到目前为止,我已经创建了以下类: - Card:保存创建一张牌 - Deck:创建一个装满所有 52 张牌的牌组 - Hand:持有一张牌的“手” - Player:创建一个供游戏使用的 Player - BlackJackTest:在这里我正在测试游戏的所有功能,试图让某些东西正常工作!

我目前已经到了可以展示所有 52 张牌的程度,并且还可以将 2 张牌发给一手牌并展示这手牌。但是我在接下来的步骤中遇到了很多麻烦。理想情况下,在“BlackJackTest”类中​​,我希望将其用作游戏引擎,在其中输入 X 数量的玩家及其姓名,它会创建玩家,并循环通过系统来玩游戏。

我的问题是我完全坚持下一步应该做什么,或者我做错了什么。我的下一个任务应该是实现一个功能,以便我可以让最多 3 名人类玩家对抗庄家,但我不确定如何做到这一点……我还应该实现我不确定的击中/站立功能我应该在哪里或如何编码这些。

任何帮助表示赞赏!

这是我的代码:

import java.util.Scanner;

public class BlackJackTest {

    public static void main(String[] args) {

        /*System.out.println(deck.getCard(0).toString());
        System.out.println(deck.getCard(0).getSuit());
        System.out.println(deck.getCard(0).getSuitCode());
        System.out.println(deck.getCard(0).getValue());
        System.out.println(deck.getCard(0).getValueCode());
        System.out.println();
        System.out.println(deck.cardsLeft());
        hand.addCard( deck.dealCard() );
        hand.addCard( deck.dealCard() );
        hand.showHand();
        System.out.println(deck.cardsLeft());
        System.out.println(hand.getHandSize());
        System.out.println(hand.getCard(0));
        System.out.println(hand.getCard(1));
        System.out.println(hand.getBlackJackValue());
        System.out.println();
        */

        Deck deck = new Deck();

        Hand p1hand = new Hand();
        Player player = new Player();

        System.out.println("Enter your name: ");
        player.setName(sc.nextLine());

        player.setHand(p1hand);

        p1hand.addCard( deck.dealCard() );
        p1hand.addCard( deck.dealCard() );

        System.out.println(player.getName() + ": ");
        p1hand.showHand();

您的模型类有一个良好的开端,我将开始处理项目的视图和控制器部分。虽然您当然可以修改 main() 以合并多个玩家(只需实例化多个玩家对象,将它们存储在列表中,然后循环发牌),但如果/当您决定移动时,您将不得不丢弃很多它到非控制台视图和控制器。

您的控制器设计将与您如何接收和响应用户输入(即击中/站立)有很大关系。它的工作是将来自视图(当前通过console.in)的输入中继到模型。因此,您的视图将显示一个提示,询问用户他们想要做什么,阅读他们的响应,并通知控制器。控制器会将此输入映射到模型类中的适当对象/方法。

希望这会有所帮助!
