javascript - 石头、纸、剪刀游戏 - 重复 5 轮

问题描述

我正在建造石头剪刀布任务。目前我的代码仅适用于 1 轮。我不确定如何在重复 5 轮的同时保持分数。我的印象是我至少需要一个 for 循环，大致如下：

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

但我不知道在哪里将它插入我的代码。我在网上环顾四周，我找不到一个足够简单的资源来理解不开始使用 switch 方法或任何其他更高级的代码来构建游戏的资源。任何帮助，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);

解决方案

我已经编辑了你的代码片段，希望它能满足你的需要:)

只需将以下代码放入 for 循环

let playerSelection = prompt("选择一个动作");
const computerSelection = computerPlay()
console.log(playRound(playerSelection, computerSelection))
console.log("你的分数 = " + 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);
}
