如何在 discord 机器人中播放和排队歌曲？
How do I stream and queue up songs in a discord bot?
我想做什么？
- 按名称搜索音乐
- 流式传输音乐而不是下载和播放它
- 如果一首歌曲已经在播放，则将歌曲加入队列
- 输出给作者“播放[url]”
我的代码：
async def play(ctx, url : str):
song_there = os.path.isfile("song.mp3")
try:
if song_there:
os.remove("song.mp3")
except PermissionError:
await ctx.send("Wait for the current playing music to end or use the 'stop' command")
return
channel = ctx.author.voice.channel
'''voiceChannel = discord.utils.get(ctx.guild.voice_channels, name=channel.name)'''
voice_client = discord.utils.get(client.voice_clients, guild=ctx.guild)
if voice_client == None:
await channel.connect()
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'mp3',
'preferredquality': '192',
}],
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download([url])
for file in os.listdir("./"):
if file.endswith(".mp3"):
os.rename(file, "song.mp3")
voice.play(discord.FFmpegPCMAudio("song.mp3"))
这段代码非常基础。它使用 yt-dl，并且仅当您粘贴 YouTube 视频的 url 时才有效。
它下载并播放歌曲，机器人播放音乐需要时间
无法排队歌曲
这是我第一次制作机器人，我在阅读和理解文档方面并没有真正的经验，因为我才刚刚开始制作 python 项目。
这就是我们在 Rage 机器人中制作音乐命令的方式，它非常有用
