Java Rock Paper游戏循环太多次 [英] Java Rock Paper Game Loops Too Many Times

问题描述

我不得不做一个剪刀石头布游戏，在那儿你要在电脑前玩.1,2,3用于石头，纸张，剪刀.它循环播放5次，并显示计算机获胜和玩家获胜的数量.除了循环之外，我已完成所有工作.当您输入大于3的数字时，假设您说无效"并循环播放，直到您玩了5个有效游戏为止.但是，如果您输入的错误答案数量奇异，那么您就可以玩6场游戏，而如果您输入的错误答案数量偶数则可以使您玩5场游戏.我需要它使您能够玩5场比赛，无论赔率是奇数还是偶数.请帮忙.

I had to make a rock paper scissors game, where you play against the computer. 1,2,3 are used for rock, paper, scissors.It loops 5 times, and shows the amount of computer wins and player wins. I got everything to work, except for the looping. When you put a number higher than 3, it's suppose to say "Invalid" and loop until you play 5 valid games. However if you you put an odd amount of wrong answers, it makes you play 6 games, and if you put an even amount of wrong answers, it makes you play 5 games. I need it to make you play 5 games regardless of odd and even amounts wrong. Please help.

public static void main(String[] args) {
    Scanner reader = new Scanner(System.in);
    int player = 0, computer = 0;
    int computerScore = 0, playerScore = 0;
    int loops = 0;

    int rock = 1;
    int paper = 2;
    int scissors = 3;

    for (int i = 1; i < 6; i++) {


        computer = (int) (Math.random() * 3) + 1;
        System.out.println("Enter 1 for Rock, 2 for Paper, 3 for Scissors");
        player = reader.nextInt();


        if (player > scissors) {
            System.out.println("Not a valid response");
            System.out.println("Enter 1 for Rock, 2 for Paper, 3 for Scissors");
            player = reader.nextInt();
            i--;

        }


        if (player == computer) {
            System.out.println("Tie");
        } else if (player == rock) {

            if (computer == paper) {
                System.out.println("Player picked Rock, Computer picked Paper, Computer wins");
                computerScore++;
            } else if (computer == scissors) {
                System.out.println("Player picked Rock, Computer picked Scissors, Player wins");
                playerScore++;
            }
        } else if (player == paper) {

            if (computer == rock) {
                System.out.println("Player picked Paper, Computer picked Rock , Player wins");
                playerScore++;
            } else if (computer == scissors) {
                System.out.println("Player picked Paper, Computer picked Scissors, Computer wins");
                computerScore++;
            }
        } else if (player == scissors) {
            if (computer == rock) {
                System.out.println("Player picked Scissors, Computer picked Rock , Computer wins");
                computerScore++;
            } else if (computer == paper) {
                System.out.println("Player picked Scissors, Computer picked Paper, Player wins");
                playerScore++;
            }

        }

    }
    System.out.println("");
    System.out.println("Computer Wins " + computerScore);
    System.out.println("Player Wins " + playerScore);

}

推荐答案

为了简化操作，我建议使用while循环.

To make things easier, I suggest using a while loop.

E.G:

Scanner reader = new Scanner (System.in);
int computerScore = 0, playerScore = 0;

int rock = 1;
int paper = 2;
int scissors = 3;
int numberOfPlayerTurns = 0;

final int MAX_PLAYER_TURNS = 5;
while (numberOfPlayerTurns < MAX_PLAYER_TURNS)
{
    int computer = (int) (Math.random() * 3) + 1;
    int player = reader.nextInt();
    System.out.println("Enter 1 for Rock, 2 for Paper, 3 for Scissors");

    // invalid
    if (player > scissors || player <= 0)
    {
        System.out.println("Not a valid response");
    }
    else
    {
        numberOfPlayerTurns++;

        if (player == computer) 
        {
            System.out.println("Tie");
        }
        else if (player == rock ) 
        {
            if(computer == paper)
            {
                System.out.println ("Player picked Rock, Computer picked Paper, Computer wins");
                computerScore++;
            }    
            else
            {
                System.out.println ("Player picked Rock, Computer picked Scissors, Player wins");
                playerScore++;
            }
        }
        else if (player == paper) 
        {
            if(computer == rock)
            {
                System.out.println ("Player picked Paper, Computer picked Rock , Player wins");
                playerScore++;
            }
            else
            {
                System.out.println ("Player picked Paper, Computer picked Scissors, Computer wins");
                 computerScore++;
            }
        }
        // scissors
        else
        {
            if(computer == rock)
            {
                System.out.println ("Player picked Scissors, Computer picked Rock , Computer wins");
                computerScore++;
            }    
            else
            {
                System.out.println ("Player picked Scissors, Computer picked Paper, Player wins");
                playerScore++;
            }
        }
    }
}
System.out.println("");
System.out.println("Computer Wins " + computerScore);
System.out.println("Player Wins " + playerScore);
