Question

我正在尝试仅对执行！pages命令的特定用户更改bot反应，我尝试了message.author和reaction.message.author == message.author，但没有成功！

问题在于，当某人使用此命令时，它也将对其他人有用，这不是我期望的。

这是代码

from discord.ext import commands

bot = commands.Bot(command_prefix='!')

left = '⏪'
right = '⏩'

messages = ("1", "2", "3")

def predicate(message, l, r):
    def check(reaction, user):
        if reaction.message.id != message.id or user == bot.user:
            return False
        if l and reaction.emoji == left and reaction.message.author == message.author:
            print('Left')
            return True
        if r and reaction.emoji == right and reaction.message.author == message.author:
            print('Right')
            return True
        return False

    return check


@bot.command(pass_context=True)
async def pages(ctx):
    index = 0
    msg = None
    action = ctx.send
    while True:
        res = await action(content=messages[index])
        if res is not None:
            msg = res
        l = index != 0
        r = index != len(messages) - 1

        if l:
            await msg.add_reaction(left)
        if r:
            await msg.add_reaction(right)
        react, user = await bot.wait_for('reaction_add', check=predicate(msg, l, r))
        if react.emoji == left and user == ctx.author:
            index -= 0
            await msg.delete()
            print(f'Left {index}')
            action = ctx.send
        elif react.emoji == right and user == ctx.author:
            index += 1
            await msg.delete()
            print(f'Right {index}')
            action = ctx.send
bot.run('token')

您可能需要对照user检查ctx.author（reaction.message.author将是您的漫游器）。这意味着我们在创建支票时需要通过作者：

def predicate(message, l, r, author):
    def check(reaction, user):
        if author.id != user.id:
            return False
        if reaction.message.id != message.id or user == bot.user:
            return False
        if l and reaction.emoji == left:
            return True
        if r and reaction.emoji == right:
            return True
        return False

    return check

react, user = await bot.wait_for('reaction_add', check=predicate(msg, l, r, ctx.author))

检查响应用户是否不适用于特定用户？
