所以我这里有一个功能齐全的 java 轮盘游戏，在 eclipse 上运行。我想通过允许用户指定他们想要在同一个游戏中加入多少玩家，而不是两个硬编码的玩家来改进它。目前我为玩家 1 和 2 设置了一个单独的名字，这样我和一个朋友就可以玩了，但我觉得这会让它更加通用。目标是获取我现在拥有的代码并学习如何获取指定的数字，将其放入循环中以生成玩家对象（每个都有自己的名称）并使程序仍然可以运行。
我有三个类，Player 类拥有我的构造函数和支付方法，还有 getName() getMoney() 方法。Roulette 类女巫是程序的主要方法，应添加此循环以添加玩家对象。以及保持随机生成的球位置的Wheel类等等。
这是第一堂课：
import java.util.Scanner;
//************************************************************************
// Class Player represents one roulette player.
//************************************************************************
public class Player
{
private int bet, money, betType, number, betNet;
@SuppressWarnings("unused")
private static int houseWins;
private String name;
private Scanner scan = new Scanner(System.in);
//=====================================================================
// The Player constructor sets up name and initial available money.
//=====================================================================
public Player (String playerName, int initialMoney)
{
name = playerName;
money = initialMoney;
} // constructor Player
//=====================================================================
// Returns this player's name.
//=====================================================================
public String getName()
{
return name;
} // method getName
//=====================================================================
// Returns this player's current available money.
//=====================================================================
public int getMoney()
{
return money;
} // method getMoney
//=====================================================================
// returns the net bets for that player
//=====================================================================
public int getNet()
{
return betNet;
}
//=====================================================================
// Prompts the user and reads betting information.
//=====================================================================
@SuppressWarnings("static-access")
public void makeBet(Wheel Wheel)
{
Scanner scan = new Scanner(System.in);
System.out.print("How much do you want to bet " + name + "? : ");
bet = scan.nextInt();
if(bet>=money)
{
System.out.println("im going all in!");
bet= money;
money = money-bet;
}
else
{
money = money-bet;
}
Wheel.betOptions();
System.out.println("Choose your bet type: ");
betType = scan.nextInt();
if(betType == 3){
System.out.println("your'e betting on: a number");
while(true){
System.out.println("Please enter the number you "
+ "wish to bet on from 1 to 36: ");
number = scan.nextInt();
if(number <1 || number > 36)
{
System.out.println("This Number is not in "
+ "the desired range.");
}
else
{
break;
}
}
}
}
// method makeBet
//=====================================================================
// Determines if the player wants to play again.
//=====================================================================
public boolean playAgain(Scanner scan)
{
String answer;
System.out.println (name + " Play again [Y/N]? ");
answer = scan.nextLine();
return (answer.equals("y") || answer.equals("Y"));
}
// method playAgain
public void payment(Wheel Wheel2)
{
int winnings = Wheel2.payoff(bet, betType, number);
money += winnings;
if(winnings > 0)
{
betNet += (winnings-bet);
Roulette.setHouseWins(-(winnings-bet));
}
else
{
betNet -= bet;
Roulette.setHouseWins((bet));
}
// =========================================================
// if player runs out of money.
// =========================================================
if(money < 1)
{
Scanner scan = new Scanner(System.in);
System.out.println(name + ", you're out of money. "
+ "Do you want to bet more? [Y/N] ");
String answer= scan.nextLine();
if(answer.equals("y") || answer.equals("Y"))
{
if (betNet>-200)
{
System.out.println("You bought back in for 100");
money +=100;
}
else {
System.out.println("Sorry buddy, your cutt off from the credit line.");
money = 0;
}
}
}
//setHouseWins(betNet);
System.out.println(" Testing to see how much is "
+ "betNet keeping track of: " + betNet);
}
}
然后是 Wheel 类：
//************************************************************************
// Class Wheel represents a roulette wheel and its operations. Its
// data and methods are static because there is only one wheel.
//************************************************************************
public class Wheel
{
// public name constants -- accessible to others
public final static int BLACK = 0; // even numbers
public final static int RED = 1; // odd numbers
public final static int GREEN = 2; // 00 OR 0
public final static int NUMBER = 3; // number bet
public final static int MIN_NUM = 1; // smallest number to bet
public final static int MAX_NUM = 36; // largest number to bet
// private name constants -- internal use only
private final static int MAX_POSITIONS = 38; // number of positions on wheel
private final static int NUMBER_PAYOFF = 35; // payoff for number bet
private final static int COLOR_PAYOFF = 2; // payoff for color bet
// private variables -- internal use only
private static int ballPosition; // 00, 0, 1 .. 36
private static int color; // GREEN, RED, OR BLACK
//=====================================================================
// Presents welcome message
//=====================================================================
public static void welcomeMessage()
{
System.out.println("Welcome to a simple version of roulette game.");
System.out.println("You can place a bet on black, red, or a number.");
System.out.println("A color bet is paid " + COLOR_PAYOFF + " the bet amount.");
System.out.println("A number bet is paid " + NUMBER_PAYOFF + " the bet amount.");
System.out.println("Have fun and good luck!\n");
}
//=====================================================================
// Presents betting options
//=====================================================================
public static void betOptions()
{
System.out.println("Betting Options:");
System.out.println(" 1. Bet on black");
System.out.println(" 2. Bet on red");
System.out.println(" 3. Bet on a number between " + MIN_NUM +
" and " + MAX_NUM);
System.out.println();
}
//=====================================================================
// method spins the wheel
//=====================================================================
public int spin()
{
ballPosition= (int)(Math.random() * MAX_POSITIONS + 1);;
if(ballPosition < 37)
{
if(ballPosition % 2 == 0)
{
color = BLACK;
}
else
{
color = RED;
}
}
else
{
color = GREEN;
}
System.out.print("the Result is: "+ ballPosition
+ " and color is: ");
if (color == BLACK)
{
System.out.println("BLACK.");
}
else if (color == RED)
{
System.out.println("RED.");
}
else
{
System.out.println("GREEN.");
}
return ballPosition;
}
//=====================================================================
// calculates the payoff
//=====================================================================
public int payoff( int bet, int betType, int number)
{
if (color == GREEN)
{
return 0;
}
else if (betType == 1 && color == BLACK)
{
return bet * COLOR_PAYOFF;
}
else if (betType == 2 && color == RED)
{
return bet * COLOR_PAYOFF;
}
else if (betType == 3 && number == ballPosition)
{
return bet * NUMBER_PAYOFF;
} else return 0;
}
}
最后是主要方法轮盘赌类：
import java.util.*;
//************************************************************************
// Class Roulette contains the main driver for a roulette betting game.
//************************************************************************
public class Roulette
{
private static int houseMoney=0;
//=====================================================================
// Contains the main processing loop for the roulette game.
//=====================================================================
public static void main (String[] args)
{
Scanner scan = new Scanner(System.in);
String name1 = "jane"; String name2 = "don";
Wheel wl1 = new Wheel();
System.out.println("please enter a name for player 1: ");
name1 = scan.nextLine();
System.out.println("please enter a name for player 2: ");
name2 = scan.nextLine();
Player player1 = new Player (name1, 100); // $100 to start for Jane
Player player2 = new Player (name2, 100); // $100 to start for Dave
boolean bl1 = true;
boolean bl2 = true;
Wheel.welcomeMessage();
while (bl1 || bl2)
{
System.out.println ("Money available for " + player1.getName()
+ ": " + player1.getMoney());
if(bl1)player1.makeBet(wl1);
System.out.println ("Money available for " + player2.getName()
+ ": " + player2.getMoney());
if(bl2)player2.makeBet(wl1);
wl1.spin();
if(bl1 == true)
{
//initiate the payment
player1.payment(wl1);
System.out.println ("Money available for " + player1.getName() + ": "
+ player1.getMoney());
// check weather play the game again
if(!player1.playAgain(scan))
{
bl1 = false;
System.out.println(player1.getName()+" total wins/losses: "
+ player1.getNet());
}
}
// check the boolean value
if(bl2 == true)
{
//initiate the payment
player2.payment(wl1);
System.out.println ("Money available for " +
player2.getName() + ": " + player2.getMoney());
// check weather play the game again
if(!player2.playAgain(scan))
{
bl2 = false;
System.out.println(player2.getName()+ " total wins/losses: "
+ player2.getNet());
}
}
}
System.out.println();
System.out.printf("House %s: $%d", houseMoney > 0 ? "Wins" : "Losses", houseMoney);
System.out.println();
System.out.println ("Game over! Thanks for playing.");
}
public static void setHouseWins(int Winnings)
{
houseMoney += Winnings;
}
}
我尝试了几种不同的方法来生成播放器对象，但我认为真正的问题是为每个想要退出以停止播放的播放器提供一个布尔对象。请帮助一个人！（Ps：请随意使用此程序作为您自己的轮盘游戏的基础，因为它的功能非常好。）
