ctx.voice_client.pause() 导致机器人离开语音通话而不是暂停音频

Question

我想弄清楚为什么我的机器人会离开语音通道而不是暂停当前播放的音频。这是我的代码以及我尝试过的其他代码：

@commands.command(brief = "Plays a locally hosted song.") 
async def play(self, ctx, *, arg): 
    await ctx.send(f"Joining voice channel: **{ctx.author.voice.channel}**")
    destination = ctx.author.voice.channel
    await destination.connect()
    await ctx.send(f"Joined voice channel: **{ctx.author.voice.channel}**")
    
    voice = discord.utils.get(self.client.voice_clients, guild=ctx.guild)
    voice.play(discord.FFmpegPCMAudio(source=f"./audio/{arg}.flac"))

    while voice.is_playing(): 
        await asyncio.sleep(.1)
    
    await voice.disconnect() 

@commands.command(brief = "Pauses the currently playing song.") 
async def pause(self, ctx): 
    ctx.voice_client.pause()

我也试过了：

@commands.command(brief = "Pauses the currently playing song.") 
async def pause(self, ctx): 
   voice = discord.utils.get(self.client.voice_clients, guild=ctx.guild)

    if voice.is_playing():
        voice.pause()
    else: 
        await ctx.send("There is currently no audio playing.")

但是，这实现了与以前相同的结果。该机器人在断开呼叫时也不会引发任何错误。任何帮助将不胜感激。

我在代码中发现了您的错误。在播放命令中，您检查客户端是否正在播放，如果没有则断开连接。这是唯一的问题。要修复它，您只需要更改您的 while 循环。您可以复制我的代码（包括解释）或直接编辑您的代码。

使用的文档：

Discord.py Documentation

代码：

@commands.command(brief="Plays a locally hosted song.")
    async def play(self, ctx, *, arg):
        await ctx.send(f"Joining voice channel: **{ctx.author.voice.channel}**")

        # Replaced Destination with ctx.voice_client, Added part where it checks if its already connected and needs to move to another channel
        if ctx.voice_client is None:
            await ctx.author.voice.channel.connect()
        else:
            await ctx.voice_client.move(ctx.author.voice.channel)

        await ctx.send(f"Joined voice channel: **{ctx.author.voice.channel}**")

        # Replaced voice with ctx.voice_client
        ctx.voice_client.play(discord.FFmpegPCMAudio(source=f"./audio/{arg}.flac"))

        # Edited Loop because it caused the Bot to disconnect
        # Loop now runs if Bot is connected to channel
        while ctx.voice_client.is_connected():
            # checks if the bot is the only one in the channel
            if len(ctx.voice_client.channel.members) == 1:
                # disconnects
                await ctx.voice_client.disconnect()
                break
            # checks if client is pause
            elif ctx.voice_client.is_paused():
                await asyncio.sleep(1)
            # Checks if client is playing
            elif ctx.voice_client.is_playing():
                await asyncio.sleep(1)
            # if nothing of the above is fulfilled
            else:
                # disconnect
                await ctx.voice_client.disconnect()
                break

    @commands.command(brief="Pauses the currently playing song.")
    async def pause(self, ctx):
        # Checks if music is playing and pauses it, otherwise sends the player a message that nothing is playing
        try:
            ctx.voice_client.pause()
        except:
            await ctx.send(f"{ctx.author.mention} i'm not playing music at the moment!")


    @commands.command(brief="Resumes the paused song.")
    async def resume(self, ctx):
        # Checks if music is paused and resumes it, otherwise sends the player a message that nothing is playing
        try:
            ctx.voice_client.resume()
        except:
            await ctx.send(f"{ctx.author.mention} i'm not playing music at the moment!")
