我正在建造石头，剪刀的任务。在我的代码只工作1轮的那一刻。我不知道我如何才能保持这个分数，同时重复5轮。我的印象是，我需要一个for循环，至少在各个回合中是这样的，大致如下：

for(i=0; i<5;i++);

但我不知道该把它插到我的代码里。我在网上环顾了一下，我找不到足够简单的资源，不需要使用开关方法或任何其他更高级的代码来构建游戏。任何帮助都将不胜感激。谢谢。

function computerPlay() {
  let random = Math.random();
  if (random <= 0.3333) {
    return "paper";
  } else if (random >= 0.6666) {
    return "rock";
  } else {
    return "scissors";
  }
}


function playRound(playerSelection, computerSelection) {
  if (playerSelection.toLowerCase() === "rock") {
    if (computerSelection === "paper") {
      computerScore++;
      return lose;
    } else if (computerSelection === "rock") {
      return tie;
    } else {
      userScore++;
      return win;
    }
  }

  if (playerSelection.toLowerCase() === "scissors") {
    if (computerSelection === "paper") {
      userScore++;
      return win;
    } else if (computerSelection === "rock") {
      computerScore++;
      return lose;
    } else {
      return tie;
    }
  }

  if (playerSelection.toLowerCase() === "paper") {
    if (computerSelection === "paper") {
      return tie;
    } else if (computerSelection === "rock") {
      userScore++;
      return win;
    } else {
      computerScore++;
      return lose;
    }
  }
}


let userScore = parseInt(0);
let computerScore = parseInt(0);
let win = "You win"
let lose = "You lose"
let tie = "It is a tie"
let playerSelection = prompt("Pick a move");
const computerSelection = computerPlay()
console.log(playRound(playerSelection, computerSelection))
console.log("your score = " + userScore);
console.log("Computer's score = " + computerScore);

loops

recursion

我编辑了您的代码片段，希望它能满足您的需要:)

只需将下面的代码放入for循环

让playerSelection =提示符(“选择一个移动”)； const computerSelection = computerPlay() console.log(playRound(playerSelection，computerSelection)) Console.log(“您的分数=”+ userScore)； Console.log(“计算机分数=”+ computerScore)；

function computerPlay() {
  let random = Math.random();
  if (random <= 0.3333) {
    return "paper";
  } else if (random >= 0.6666) {
    return "rock";
  } else {
    return "scissors";
  }
}


function playRound(playerSelection, computerSelection) {
  if (playerSelection.toLowerCase() === "rock") {
    if (computerSelection === "paper") {
      computerScore++;
      return lose;
    } else if (computerSelection === "rock") {
      return tie;
    } else {
      userScore++;
      return win;
    }
  }

  if (playerSelection.toLowerCase() === "scissors") {
    if (computerSelection === "paper") {
      userScore++;
      return win;
    } else if (computerSelection === "rock") {
      computerScore++;
      return lose;
    } else {
      return tie;
    }
  }

  if (playerSelection.toLowerCase() === "paper") {
    if (computerSelection === "paper") {
      return tie;
    } else if (computerSelection === "rock") {
      userScore++;
      return win;
    } else {
      computerScore++;
      return lose;
    }
  }
}


let userScore = parseInt(0);
let computerScore = parseInt(0);
let win = "You win"
let lose = "You lose"
let tie = "It is a tie"

for(var i=0;i<5;i++){
  let playerSelection = prompt("Pick a move");
  const computerSelection = computerPlay()
  console.log(playRound(playerSelection, computerSelection))
  console.log("your score = " + userScore);
  console.log("Computer's score = " + computerScore);
}

试试下面的代码：

循环不是一个好方法，请在这里阅读：

它允许用户玩5次。

使用递归

function computerPlay() {
    let random = Math.random();
    if (random <= 0.3333) {
        return "paper";
    } else if (random >= 0.6666) {
        return "rock";
    } else {
        return "scissors";
    }
}


function playRound(playerSelection, computerSelection) {
    if (playerSelection.toLowerCase() === "rock") {
        if (computerSelection === "paper") {
            computerScore++;
            return lose;
        } else if (computerSelection === "rock") {
            return tie;
        } else {
            userScore++;
            return win;
        }
    }

    if (playerSelection.toLowerCase() === "scissors") {
        if (computerSelection === "paper") {
            userScore++;
            return win;
        } else if (computerSelection === "rock") {
            computerScore++;
            return lose;
        } else {
            return tie;
        }
    }

    if (playerSelection.toLowerCase() === "paper") {
        if (computerSelection === "paper") {
            return tie;
        } else if (computerSelection === "rock") {
            userScore++;
            return win;
        } else {
            computerScore++;
            return lose;
        }
    }
}


let userScore = parseInt(0);
let computerScore = parseInt(0);
let win = "You win"
let lose = "You lose"
let tie = "It is a tie"

var i = 0;
const play = () => {
    let playerSelection = prompt("Pick a move");
    const computerSelection = computerPlay()
    console.log(playRound(playerSelection, computerSelection))
    console.log("your score = " + userScore);
    console.log("Computer's score = " + computerScore);
    i++;
    if (i !== 5) {
        play();
    } else {
        alert("Game Over=> User("+userScore+") vs Computer("+computerScore+")");
    }
}

play();
