我制作了一个争夺游戏命令，但由于某种原因，大写字母会使机器人崩溃

Question

我做了一个小命令，这样，如果有人，例如，输入&scramble apple，bot就会发送"这个词是：paple；。它按预期工作，但当前的问题是；苹果；而不是"；苹果"；，机器人崩溃了，说它无法获取未定义的作者

module.exports = {
name: 'scramble',
execute(message, args) {
const Discord = require('discord.js')
let givenword = args.slice(0).join(" ");

function scramble(givenword) {
var word = givenword.split("")
n = word.length
for(var i = n - 1; i > 0; i--) {
var j = Math.floor(Math.random() * (i+1));
var tmp = word[i];
word[i] = word[j]
word[j] = tmp;
}
return word.join("")
}
scrambledword = scramble(givenword)
const embed = new Discord.MessageEmbed()
.setTitle('Scramble time!')
.setColor("RANDOM")
.setDescription("The word is: " + scrambledword)
.setFooter('You have 30 seconds to try and guess it, the first person to answer correctly ')
message.channel.send({embed});
message.delete()

const filter = m => m.content.includes(givenword);
const collector = message.channel.createMessageCollector(filter, { time: 30000 });

collector.on('collect', m => {
console.log(`Collected ${m.content}`);
});

collector.on('end', collected => {
message.channel.send(`${collected.first().author} got the correct answer first! The answer was ${givenword}`);
console.log(`Collected ${collected.size} items`);
});


}
}

有人能帮我一下吗？

Answer 1

有两个错误：

1. 您需要处理案例不匹配。我建议，在对单词进行加扰之前，将其小写，并在评估它们之前将响应小写

var word= givenword.toLowercase().split("")

const filter = m => m.content.toLowercase().includes(give word)

2. 您需要处理没有做出正确猜测的情况。collected.first()未定义，因为没有赢家。我建议在打印获胜者之前先检查一下获胜者

if (collected.length <= 0) {
// send no winner message
} else {
// send the winner message
}
