我有一个关于从 CodeLyon 学到的音乐机器人的问题。他制作这个音乐机器人的视频在这里：https://www.youtube.com/watch?v=riyHsgI2IDs&list=PLbbLC0BLaGjpyzN1rg-gK4dUqbn8eJQq4&index=20
如果你很懒，不想看整个视频，这里有一个总结：
我有一个命令处理程序，名为 command_handler.js。我认为此文件用于过滤命令，但我不确定。它只是一个命令处理程序。如果你真的想要它（虽然我不知道为什么），代码在这里：
const fs = require('fs');
module.exports = (client, Discord) =>{
const command_files = fs.readdirSync('./commands/').filter(file => file.endsWith('.js'))
for(const file of command_files){
const command = require(`../commands/${file}`);
if(command.name){
client.commands.set(command.name, command);
} else {
continue;
}
}
}
一个稍微重要的文件是 message.js 文件。这个运行所有命令。这是代码，但是，就像 command_handler.js 一样，我不知道您为什么需要它。
require('dotenv').config();
//create cooldowns map
const cooldowns = new Map();
module.exports = (Discord, client, message) => {
const prefix = process.env.PREFIX;
if (!message.content.startsWith(prefix) || message.author.bot) return;
const args = message.content.slice(prefix.length).split(/ +/)
const cmd = args.shift().toLowerCase();
const command = client.commands.get(cmd) || client.commands.find(a => a.aliases && a.aliases.includes(cmd));
//If cooldowns map doesn't have a command.name key then create one.
if(!cooldowns.has(command.name)){
cooldowns.set(command.name, new Discord.Collection());
}
const current_time = Date.now();
const time_stamps = cooldowns.get(command.name);
const cooldown_amount = (command.cooldown) * 1000;
//If time_stamps has a key with the author's id then check the expiration time to send a message to a user.
if(time_stamps.has(message.author.id)){
const expiration_time = time_stamps.get(message.author.id) + cooldown_amount;
if(current_time < expiration_time){
const time_left = (expiration_time - current_time) / 1000;
return message.reply(`Please wait ${time_left.toFixed(1)} more seconds before using ${command.name}`);
}
}
//If the author's id is not in time_stamps then add them with the current time.
time_stamps.set(message.author.id, current_time);
//Delete the user's id once the cooldown is over.
setTimeout(() => time_stamps.delete(message.author.id), cooldown_amount);
try{
command.execute(client, message, args, cmd, Discord);
} catch (err){
message.reply("There was an error trying to execute this command!");
console.log(err);
}
}
现在是最重要的文件：播放歌曲的文件。它是用 play 关键字激活的，或者别名跳过和停止。该文件名为 play.js。代码如下：
const ytdl = require('ytdl-core');
const ytSearch = require('yt-search');
//Global queue for your bot. Every server will have a key and value pair in this map. { guild.id, queue_constructor{} }
const queue = new Map();
module.exports = {
name: 'play',
aliases: ['skip', 'stop'], //We are using aliases to run the skip and stop command follow this tutorial if lost: https://www.youtube.com/watch?v=QBUJ3cdofqc
cooldown: 0,
description: 'Advanced music bot',
async execute(client, message,args, cmd, Discord){
//Checking for the voicechannel and permissions (you can add more permissions if you like).
const voice_channel = message.member.voice.channel;
if (!voice_channel) return message.channel.send('You need to be in a channel to execute this command!');
const permissions = voice_channel.permissionsFor(message.client.user);
if (!permissions.has('CONNECT')) return message.channel.send('You dont have the correct permissions');
if (!permissions.has('SPEAK')) return message.channel.send('You dont have the correct permissions');
//This is our server queue. We are getting this server queue from the global queue.
const server_queue = queue.get(message.guild.id);
//If the user has used the play command
if (cmd === 'play'){
if (!args.length) return message.channel.send('You need to send the second argument!');
let song = {};
//If the first argument is a link. Set the song object to have two keys. Title and URl.
if (ytdl.validateURL(args[0])) {
const song_info = await ytdl.getInfo(args[0]);
song = { title: song_info.videoDetails.title, url: song_info.videoDetails.video_url }
} else {
//If there was no link, we use keywords to search for a video. Set the song object to have two keys. Title and URl.
const video_finder = async (query) =>{
const video_result = await ytSearch(query);
return (video_result.videos.length > 1) ? video_result.videos[0] : null;
}
const video = await video_finder(args.join(' '));
if (video){
song = { title: video.title, url: video.url }
} else {
message.channel.send('Error finding video.');
}
}
//If the server queue does not exist (which doesn't for the first video queued) then create a constructor to be added to our global queue.
if (!server_queue){
const queue_constructor = {
voice_channel: voice_channel,
text_channel: message.channel,
connection: null,
songs: []
}
//Add our key and value pair into the global queue. We then use this to get our server queue.
queue.set(message.guild.id, queue_constructor);
queue_constructor.songs.push(song);
//Establish a connection and play the song with the vide_player function.
try {
const connection = await voice_channel.join();
queue_constructor.connection = connection;
video_player(message.guild, queue_constructor.songs[0]);
} catch (err) {
queue.delete(message.guild.id);
message.channel.send('There was an error connecting!');
throw err;
}
} else{
server_queue.songs.push(song);
return message.channel.send(`? **${song.title}** added to queue!`);
}
}
else if(cmd === 'skip') skip_song(message, server_queue);
else if(cmd === 'stop') stop_song(message, server_queue);
}
}
const video_player = async (guild, song) => {
const song_queue = queue.get(guild.id);
//If no song is left in the server queue. Leave the voice channel and delete the key and value pair from the global queue.
if (!song) {
song_queue.voice_channel.leave();
queue.delete(guild.id);
return;
}
const stream = ytdl(song.url, { filter: 'audioonly' });
song_queue.connection.play(stream, { seek: 0, volume: 0.5 })
.on('finish', () => {
song_queue.songs.shift();
video_player(guild, song_queue.songs[0]);
});
await song_queue.text_channel.send(`? Now playing **${song.title}**`)
}
const skip_song = (message, server_queue) => {
if (!message.member.voice.channel) return message.channel.send('You need to be in a channel to execute this command!');
if(!server_queue){
return message.channel.send(`There are no songs in queue ?`);
}
server_queue.connection.dispatcher.end();
}
const stop_song = (message, server_queue) => {
if (!message.member.voice.channel) return message.channel.send('You need to be in a channel to execute this command!');
server_queue.songs = [];
server_queue.connection.dispatcher.end();
}
某些字符串中有一些表情符号。如果你看不到它们，我很抱歉，但它们不是很重要。
你看，我的前缀是>>。问题是，当我在 Discord 聊天中输入>>播放，然后输入任何歌曲时，无论是什么歌曲，机器人都会弹出语音通道约五分之一秒，然后再次弹出。我什至不能听这首歌。只是为了让你知道，我在语音频道。有解决办法吗？如果没有，是否有解决方法？
我希望我已经描述了足够多的问题。如果你需要我在这里添加一些东西，你能在评论中告诉我吗？如果我需要以某种方式重启我的机器人，或者对我的 Discord 服务器做一些事情，或者更改一些设置，或者下载一些软件包，请告诉我。我需要绝对准确的答案。非常感谢帮助！

答案 0 :(得分：-2)
我只知道问题出在哪里，我真的帮不上忙，但我也在努力解决这个问题！
