Discord.py 检测反应

Question

我正在制作一个使用 DM 的 Discord.py 机器人。我有一个命令，机器人会向您发送消息，要求您对您尝试执行的操作做出反应。问题是当用户添加它不起作用的反应时。

这是我目前所拥有的

@client.command()
async def suggest(ctx):
        embed = discord.Embed(
            title = 'What kind of suggestion are you making?',
            description = '<:Yes:755187983585509517> Car Suggestion\n<:Maybe:755187983623258123> Job Suggestion\n<:No:755187984067854367> Other Suggestion Type',
            colour = discord.Colour.green()
        )

        await ctx.message.delete()
        await ctx.send(f'{ctx.message.author.mention} Please check your DMs to continue!')

        embed.set_footer(text='Pembroke Pines Bot - Made By: parker02311')

        msg = await ctx.author.send(embed=embed)
        await msg.add_reaction('<:Yes:755187983585509517>')
        await msg.add_reaction('<:Maybe:755187983623258123>')
        await msg.add_reaction('<:No:755187984067854367>')

        def check(reaction, user):
            return user == msg.author and str(reaction.emoji) == '<:Yes:755187983585509517>'

        try:
            reaction, user = await client.wait_for('reaction_add', timeout=60.0, check=check)
        except asyncio.TimeoutError:
            await ctx.author.send("Timed out")
        else:
            embed = discord.Embed(
                title = 'Car Suggestion',
                description = 'What is your username?',
                colour = discord.Colour.green()
            )

            embed.set_footer(text='Pembroke Pines Bot - Made By: parker02311')
            await ctx.author.send(embed=embed)
            
            def check(m):
                return m.content
            msg = await client.wait_for('message', check=check)
            await ctx.author.send(f'Okay, your username is: **{msg}**')

            embed = discord.Embed(
                title = 'Car Suggestion',
                description = 'What is the car model?',
                colour = discord.Colour.green()
            )

            embed.set_footer(text='Pembroke Pines Bot - Made By: parker02311')
            await ctx.author.send(embed=embed)
            msg = await client.wait_for('message', check=check)
            await ctx.author.send(f'Okay, the model is: **{msg}**')

        #channel = client.get_channel(734882692537253900)
        embed = discord.Embed(
            description = f'{ctx.message.author.mention} **made a suggestion\nChannel:** {ctx.message.channel}\n**Message Content:** {ctx.message.content}',
            colour = discord.Colour.red()
        )
        embed.set_footer(text='Pembroke Pines Bot - Made By: parker02311')
        embed.set_author(name=ctx.message.author)
        await logschannel.send(embed=embed)

Answer 1

原来如此

return user == msg.author and str(reaction.emoji) == '<:Yes:755187983585509517>'

我正在检查 BOT 添加的反应而不是用户，希望这可以节省其他人的时间。

这是我想出的一个建议命令：

@client.command()
async def suggest(ctx, *, suggestion):
    author = ctx.message.author
    file = open("suggestions.txt", "a+")
    file.write(str(author) + " : " + suggestion + "\n")
    embed = discord.Embed(title='Suggestion',
                          description="This Was Suggested By",
                          color=0xE0B802)

    embed.set_footer(text=f"Made By {ctx.author.mention}")
    embed.set_author(name=f"{author}")
    embed.add_field(name=author, value=suggestion)
    await ctx.send("Suggestion Submitted")
    msg = await channel.send(embed=embed)
    await msg.add_reaction('?')
    await msg.add_reaction('?')
    await ctx.send(f"{ctx.author.mention} suggested {suggestion}!")

它将发送包含建议的嵌入并添加反应以及在其页脚中创建建议的作者。

你可以试试wait_for。例如here

@client.event
async def on_message(message):
    if message.content.startswith('$thumb'):
        channel = message.channel
        await channel.send('Send me that ? reaction, mate')

        def check(reaction, user):
            return user == message.author and str(reaction.emoji) == '?'

        try:
            reaction, user = await client.wait_for('reaction_add', timeout=60.0, check=check)
        except asyncio.TimeoutError:
            await channel.send('?')
        else:
            await channel.send('?')
