如何循环石头剪刀布游戏并让它在获胜条件下保持得分？

我尝试创建一个“游戏”功能，循环 RPS 轮次，直到玩家或计算机达到 5 分。但是，我无法让分数保持不变，游戏也不会循环。

playerSelection = prompt( ' Enter Rock, Paper, or Scissors');
let winner = 0;
let humanScore = 0;
let computerScore = 0;

function computerPlay() {
    let number = Math.floor(Math.random() * (3 + 1));
    if(number == 1)
        return 'Rock';
    else if(number == 2)
        return 'Paper';
    else return 'Scissors';
}

let computerSelection = computerPlay();
playerSelection = playerSelection.toUpperCase();
computerSelection = computerSelection.toUpperCase();



function game() {
    while( humanScore <= 5 || computerScore <= 5) {
        playRound();

    }
}


function playRound(playerSelection, computerSelection) {
    if( playerSelection === 'ROCK' && computerSelection === 'SCISSORS') {
        humanScore +=1;
        return playerSelection + ' wins vs ' + computerSelection + '. Congratulations!';
    } else if( playerSelection === 'ROCK' && computerSelection === 'PAPER') {
        computerScore +=2;
        return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
    } else if( playerSelection === 'ROCK' && computerSelection === 'ROCK') {
        return playerSelection + ' ties with ' + computerSelection + '. Try again!';
    } else if( playerSelection === 'PAPER' && computerSelection === 'ROCK') {
        humanScore +=1;
        return playerSelection + ' wins vs ' + computerSelection + '. Congratulations!';
    } else if( playerSelection === 'PAPER' && computerSelection === 'PAPER') {
        return playerSelection + ' ties with ' + computerSelection + '. Try again!';
    } else if( playerSelection === 'PAPER' && computerSelection === 'SCISSORS') {
        computerScore +=2;
        return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
    } else if( playerSelection === 'SCISSORS' && computerSelection === 'SCISSORS') {
        return playerSelection + ' ties with ' + computerSelection + '. Try again!';
    } else if( playerSelection === 'SCISSORS' && computerSelection === 'PAPER') {
        humanScore += 1;
        return playerSelection + ' wins vs ' +computerSelection + '. Congratulations!';
    } else if( playerSelection === 'SCISSORS' && computerSelection === 'ROCK') {
        computerScore +=2;
        return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
    } else return 'Enter a valid move! Refresh the damn page!';

    win_condition();
}

function win_condition() {
    if( humanScore === 5 ) {
        return 'Player Wins!';
    }
    if( computerScore === 5 ) {
        return 'Computer wins!';
    }
}

该程序执行一次并有效，但不会像我期望的那样重复。

Answer 1

您的代码中存在一些问题，如评论部分中突出显示的那样:

1. 函数 win_condition和game从来没有被调用过。
2. 函数 win_condition和playGround返回处理后的值，但被接受。
3. if( humanScore === 5 )或if( computerScore === 5 )总是假的。处理条件为humanScore <= 5 || computerScore <= 5
4. if(humanScore <= 5 || computerScore <= 5)即使玩家得分超过 5，此操作也会失败。

let winner = 0;
let humanScore = 0;
let computerScore = 0;

function initializeGame() {
  let playerSelection = prompt(' Enter Rock, Paper, or Scissors');
  let computerSelection = computerPlay();

  let msg = playRound(playerSelection, computerSelection);
  console.log(msg);
  if (humanScore <= 5 && computerScore <= 5) {
    console.log('Current score: Human: ', humanScore, ' Computer: ', computerScore)
    setTimeout(initializeGame, 0);
  } else {
    console.log(win_condition());
  }
}

function computerPlay() {
  let number = Math.floor(Math.random() * (3 + 1));
  if (number == 1)
    return 'Rock';
  else if (number == 2)
    return 'Paper';
  else return 'Scissors';
}

function playRound(playerSelection, computerSelection) {
  playerSelection = playerSelection.toUpperCase();
  computerSelection = computerSelection.toUpperCase();
  if (playerSelection === 'ROCK' && computerSelection === 'SCISSORS') {
    humanScore += 1;
    return playerSelection + ' wins vs ' + computerSelection + '. Congratulations!';
  } else if (playerSelection === 'ROCK' && computerSelection === 'PAPER') {
    computerScore += 2;
    return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
  } else if (playerSelection === 'ROCK' && computerSelection === 'ROCK') {
    return playerSelection + ' ties with ' + computerSelection + '. Try again!';
  } else if (playerSelection === 'PAPER' && computerSelection === 'ROCK') {
    humanScore += 1;
    return playerSelection + ' wins vs ' + computerSelection + '. Congratulations!';
  } else if (playerSelection === 'PAPER' && computerSelection === 'PAPER') {
    return playerSelection + ' ties with ' + computerSelection + '. Try again!';
  } else if (playerSelection === 'PAPER' && computerSelection === 'SCISSORS') {
    computerScore += 2;
    return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
  } else if (playerSelection === 'SCISSORS' && computerSelection === 'SCISSORS') {
    return playerSelection + ' ties with ' + computerSelection + '. Try again!';
  } else if (playerSelection === 'SCISSORS' && computerSelection === 'PAPER') {
    humanScore += 1;
    return playerSelection + ' wins vs ' + computerSelection + '. Congratulations!';
  } else if (playerSelection === 'SCISSORS' && computerSelection === 'ROCK') {
    computerScore += 2;
    return playerSelection + ' loses vs ' + computerSelection + '. Try again!';
  } else return 'Enter a valid move! Refresh the damn page!';
}

function win_condition() {
  if (humanScore > 5) {
    return 'Player Wins!';
  }
  if (computerScore > 5) {
    return 'Computer wins!';
  }
}

initializeGame();
