我如何检测反应？

Question

我正在尝试发出一个报价命令，在该命令中，机器人会检测提到的用户是否对 check 或 x 做出反应。

@bot.command()
@commands.has_any_role("Franchise Owner", "General Manager", "Head Coach")
async def offer(ctx, member:discord.Member, reaction):
    embed = discord.Embed()
    embed.add_field(name="<a:Loading:768095883664424971> Incoming Offer", value=f"The <:DallasCowboys:788796627161710592> have offered {member.mention}.")
    offer_sent = await ctx.send(embed=embed)
    await offer_sent.add_reaction("<a:CheckMark:768095274949935146>")
    await offer_sent.add_reaction("<a:XMark:768095331555606528>")
    await member.send("You have been offered to the <:DallasCowboys:788796627161710592>. You have 30 minutes to accept/decline.")
    await asyncio.sleep(1800) # Replace "30" with 1800, because 1800 in seconds is 30 min.
    await offer_sent.delete()
    def on_reaction(reaction, member:discord.Member):
        channel = member.channel

        def check(reaction, user):
            return user == member and str(reaction.emoji) == '<a:CheckMark:768095274949935146>'
      
        try:
            reaction, user = await bot.wait_for('reaction_add', timeout=60.0, check=check)
        except asyncio.TimeoutError:
            await channel.send(f"{member.mention} hasn't reacted in time.")
        else:
            await channel.send(f"{member.mention} has accepted <:DallasCowboys:788796627161710592> offer.")

Answer 1

我从 offer 函数中删除了反应，因为我不知道它做了什么，因为它没有在代码中使用。然后我删除了 on_reaction 函数，但将代码从内部移到了 asyncio.sleep(1800).

之前

@bot.command()
@commands.has_any_role("Franchise Owner", "General Manager", "Head Coach")
async def offer(ctx, member:discord.Member):
    embed = discord.Embed()
    embed.add_field(name="<a:Loading:768095883664424971> Incoming Offer", value=f"The <:DallasCowboys:788796627161710592> have offered {member.mention}.")
    offer_sent = await ctx.send(embed=embed)
    await offer_sent.add_reaction("<a:CheckMark:768095274949935146>")
    await offer_sent.add_reaction("<a:XMark:768095331555606528>")
    await member.send("You have been offered to the <:DallasCowboys:788796627161710592>. You have 30 minutes to accept/decline.")
    channel = ctx.channel

    def check(reaction, user):
        return user == member and str(reaction.emoji) == '<a:CheckMark:768095274949935146>'

    try:
        reaction, user = await bot.wait_for('reaction_add', timeout=60.0, check=check)
    except asyncio.TimeoutError:
        await channel.send(f"{member.mention} hasn't reacted in time.")
    else:
        await channel.send(f"{member.mention} has accepted <:DallasCowboys:788796627161710592> offer.")
    await asyncio.sleep(1800) # Replace "30" with 1800, because 1800 in seconds is 30 min.
    await offer_sent.delete()

我如何检测反应？

How can I detect reactions?

python
