如何使用 Discord.py Cogs 制作 Discord 音乐机器人

Question

我当前的项目

我正在尝试将我从 YouTube 视频制作的 Python 音乐机器人转换成齿轮，这样我的主要 Python Discord 机器人文件就不那么混乱了。

我的问题

下面我写的代码不工作。我阅读了有关 cogs 的文档，但我似乎无法找到我做错了什么。

这是我尝试编写的代码，但它

import discord
from discord.ext import commands
from discord.utils import get
import youtube_dl
import os
from time import sleep
 
rpgmusicpath = r"path\to\music.mp3"
 
class Music(commands.Cog):
    def __init__(self, client):
        self.bot = client
 
    @commands.Cog.listener()
    async def on_ready(self):
        print('Music cog successfully loaded.')
       
       
    @commands.command(pass_context=True)
    async def rpgmusic(ctx, self):
        global voice
        channel = ctx.message.author.voice.channel
        voice = get(bot.voice_clients, guild=ctx.guild)
 
        if voice and voice.is_connected():
            await voice.move_to(channel)
 
        else:
            voice = await channel.connect()
            print(f'Bot connected to voice channel {channel}\n')
   
        await ctx.send(f'Playing some RPG music in {channel}.')
        sleep(3)
        voice.play(discord.FFmpegPCMAudio('rpgmusic.mp3'), after=lambda e: print(f'RPG music in {channel} has finished playing.'))
        voice.source = discord.PCMVolumeTransformer(voice.source)
        voice.source.volume = 0.05

            print(f'Bot disconnected from channel {channel}.')
       
        else:
            print('Not able to disconnect to a voice channel because bot wasn\'t in one.')
       
    @commands.command(pass_context=True)
    async def play(ctx, url: str, self):

        voice.source = discord.PCMVolumeTransformer(voice.source)
        voice.source.volume = 0.06
 
        nname = name.rsplit('-', 2)
        await ctx.send(f'Now playing {name}.')
        print('Now playing.\n')

    bot.add_cog(Music(bot))

Answer 1

两个问题：

您没有将 bot 替换为 self.bot。

在 rpgmusic、join、leave 和 play 命令中，更改：

voice = get(bot.voice_clients, guild=ctx.guild)

收件人：

voice = get(self.bot.voice_clients, guild=ctx.guild)

您的第一个参数必须是 self，而不是 ctx:

@commands.command(pass_context=True)
async def rpgmusic(self, ctx)

@commands.command(pass_context=True)
async def join(self, ctx)

@commands.command(pass_context=True)
async def play(self, ctx)

此外，由于您有一个 join 函数，您可以在 rpgmusic 中等待它（您也不需要 global voice）：

@commands.command(pass_context=True)
    async def rpgmusic(ctx, self):
        await self.join(ctx)
        await ctx.send(f'Playing some RPG music in {channel}.')
        sleep(3)
        voice.play(discord.FFmpegPCMAudio('rpgmusic.mp3'), after=lambda e: print(f'RPG music in {channel} has finished playing.'))
        voice.source = discord.PCMVolumeTransformer(voice.source)
        voice.source.volume = 0.05
