如何修复刽子手游戏中的启动功能

Question

我一直在使用 JavaScript 在控制台中开发一个刽子手游戏，但我似乎无法弄清楚如何让它随机选择前两个类别。我知道这一定是一个简单的解决方案，但我似乎无法弄清楚。

这是我的开始游戏功能问题所在

function start () {


player.guessedLetters = []
  player.strikes = 0
  player.maxStrikes = 3
  player.display = []
  player.status = true
  displayIn = []



const game = Math.floor(Math.random() * (categories.length))
  if (game === 0) {
    console.log('The category is Easy Words')
    const selectEasyWords = easyWords[Math.floor(Math.random() * (6))]

player.display = selectEasyWords
for (let i = 0; i < selectEasyWords.length; i++) {
  if (selectEasyWords[i] === ' ') {
    displayIn.push(' ')
  } else {
    displayIn.push('_')
  }
}
    return ${displayIn.join(' ')}
  } else if (game === 1) {
    console.log('The category is Medium Words')
    const selectMediumWords = mediumWords[Math.floor(Math.random() * (6))]

player.display = selectMediumWords
for (let i = 0; i < selectMediumWords.length; i++) {
  if (selectMediumWords[i] === ' ') {
    displayIn.push(' ')
  } else {
    displayIn.push('_')
  }
}
return ${displayIn.join(' ')}


} else if (game === 1) {
    console.log('The category is Hard Words')
    const selectHardWords = hardWords[Math.floor(Math.random() * (6))]

player.display = selectHardWords
for (let i = 0; i < selectHardWords.length; i++) {
  if (selectHardWords[i] === ' ') {
    displayIn.push(' ')
  } else {
    displayIn.push('_')
  }
}
return ${displayIn.join(' ')}


} else if (game === 1) {
    console.log('The category is Extreme Words')
    const selectExtremeWords = extremeWords[Math.floor(Math.random() * (2))]

player.display = selectExtremeWords
for (let i = 0; i < selectExtremeWords.length; i++) {
  if (selectExtremeWords[i] === ' ') {
    displayIn.push(' ')
  } else {
    displayIn.push('_')
  }
}
return ${displayIn.join(' ')}


} else {
    return Where did you go wrong
  }
}

这是我的上下文代码的其余部分。

    console.log('HANGMAN\nTry to solve the puzzle by guessing letters using guess(letter).\nIf you miss a letter you get a strike.\nGet 3 strikes and you lose the game.\nTo select difficulty, type difficulty(difficulty).\nDifficulties:\nEasy\nMedium\nHard\nExtreme\nTo start game type start().')

Answer 1

如果我理解了这个问题，那么这种方法可能会奏效：你需要的是一个数组数组，所以想象一下

var gameModes=[
    ['EasyWords','AnotherEasy'],['MediumWords'],['HardWords']
]

现在选择你可以做的类别：

let game=Math.floor(Math.random() * (gameModes.length))

然后选择一个单词

function SelectWord(wordList)
{ 
 let wordIndex=Math.floor(Math.random() * (wordList.length))
 return wordList[wordIndex];
}

现在你可以把这个函数称为

let word=SelectWord(gameModes[game]);

Answer 2

看起来game是从

分配的

const game = Math.floor(Math.random() * (categories.length))

由于categories.length 为4，您将始终获得0、1、2 或3 的值。之后，您的if...else if 语句评估game === 1，而不是更改为game === 2 或game === 3所以它永远不会找到其他单词类别。另外，我建议 switch 而不是所有的 if 语句。
