Java 中的猪游戏

2024 年 9 月 10 日 | 阅读 7 分钟

“猪游戏”（Pig Game），也称为“猪骰子游戏”（Pig Dice Game）或“传猪”（Pass the Pigs），是一款简单有趣的骰子游戏，可以用Java编程语言实现。游戏涉及掷一对骰子，并根据结果累积分数。游戏的目标是成为第一个达到预定分数总和的玩家，通常是100分。在本文中，我们将探讨“猪游戏”的规则，并演示如何在Java中实现它。

猪游戏规则

游戏通常由两名或两名以上玩家进行。

在每个回合中，玩家掷一对六面骰子。
玩家根据骰子点数之和累积分数。
如果玩家掷出1点（无论哪一个骰子），则他们的回合结束，并且他们在此回合中累积的所有分数作废。
如果玩家掷出两个骰子都为1点，则他们将失去所有分数，并且回合结束。
玩家可以在回合的任何时候选择“hold”（暂停），这将把累积的分数添加到他们的总得分中。
第一个达到或超过预定分数总和（例如100分）的玩家赢得游戏。

Java 实现

要在Java中实现“猪游戏”，我们可以遵循以下步骤：

步骤1： 设置游戏

定义玩家人数和目标分数。
将每个玩家的总得分初始化为零。

步骤2： 实现骰子滚动

生成1到6之间的随机数来模拟掷骰子。
将掷出的点数加到玩家当前回合的分数中。
检查是否掷出1点（无论哪一个骰子），并处理回合结束的条件。

步骤3： 实现玩家回合

提示当前玩家掷骰子或暂停。
调用骰子滚动函数并相应地更新玩家得分。
重复此过程，直到玩家决定暂停或掷出1点。

步骤4： 实现游戏循环

在玩家之间轮流进行回合。
跟踪每个玩家的总得分。
检查是否有玩家达到或超过目标分数。

步骤5： 宣布获胜者

显示获胜者的姓名和总得分。

这是一个实现“猪游戏”的完整Java程序。

PigGame.java

import java.util.Scanner;
public class PigGame {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int targetScore = 100; // Target point total to win the game
        int numPlayers; // Number of players
        int[] playerScores; // Array to store the scores of each player
        int currentPlayer = 0; // Index of the current player
        System.out.print("Enter the number of players: ");
        numPlayers = scanner.nextInt();
        playerScores = new int[numPlayers];
        while (true) {
            System.out.println("\nPlayer " + (currentPlayer + 1) + "'s turn.");
            System.out.println("Current Score: " + playerScores[currentPlayer]);
            // Roll the dice
            int dice1 = rollDice();
            int dice2 = rollDice();
            System.out.println("Dice 1: " + dice1);
            System.out.println("Dice 2: " + dice2);
            if (dice1 == 1 && dice2 == 1) {
                // Rolled two 1's, lose all points
                playerScores[currentPlayer] = 0;
                System.out.println("Oops! You rolled two 1's. Turn score reset to 0.");
                break;
            } else if (dice1 == 1 || dice2 == 1) {
                // Rolled a single 1, end turn
                System.out.println("Oops! You rolled a 1. Turn score reset to 0.");
                break;
            } else {
                // Update the player's score
                playerScores[currentPlayer] += dice1 + dice2;
            }
            System.out.println("Turn score: " + (dice1 + dice2));
            System.out.print("Do you want to roll again (R) or hold (H)? ");
            String choice = scanner.next();
            if (choice.equalsIgnoreCase("H")) {
                // Hold, add turn score to total score
                playerScores[currentPlayer] += dice1 + dice2;
                System.out.println("Current Score: " + playerScores[currentPlayer]);
                break;
            }
        }
        // Switch to the next player's turn
        currentPlayer = (currentPlayer + 1) % numPlayers;
        // Check if any player has reached or exceeded the target score
        for (int i = 0; i < numPlayers; i++) {
            if (playerScores[i] >= targetScore) {
                System.out.println("\nPlayer " + (i + 1) + " wins with a score of " + playerScores[i] + "!");
                return;
            }
        }
    }
    // Method to simulate rolling a six-sided dice
    public static int rollDice() {
        return (int) (Math.random() * 6) + 1;
    }
}
