从无效的反应中获取输入 discord.py

Question

我想为我的机器人制作一个石头剪刀布游戏： The bot creates an embed with instructions and reacts with a "rock", "paper", and "scissor" emoji, which the user has to click to input his/her choice.

但问题是代码没有进一步执行并显示错误。

代码如下：

@client.command(aliases = ["rock_paper_scissors","rps"])
async def _rps(ctx):    #rps is short for rock, paper, scissor
    emojis = ['✊', '????️', '✌️']
    
    embedVar = discord.Embed(title="CHOOSE YOUR WEAPON!",description = "Choose between rock, paper, or scissors, {}." . format(ctx.author.mention), color = 0xff9900)
    embedVar.add_field(name=":fist: ROCK", value="React with :fist: emoji to choose rock.", inline = False)
    embedVar.add_field(name=":hand_splayed: PAPER", value="React with :hand_splayed: emoji to choose paper.", inline = False)
    embedVar.add_field(name=":v: SCISSORS", value="React with :v: emoji to choose scissors.", inline = False)
    emb = await ctx.send(embed = embedVar)

    for emoji in emojis:
        await emb.add_reaction(emoji)

    def chk(reaction):
        return reaction.emb == emb and reaction.channel == ctx.channel
    
    react = await client.wait_for('reaction_add', check=chk)

    if react == '✊':
        await ctx.send("You chose rock!")
    elif react == '????️':
        await ctx.send("You chose paper!")
    elif react == '✌️':
        await ctx.send("You chose scissors!")

我收到此错误：

discord.ext.commands.errors.CommandInvokeError: Command raised an exception: TypeError: chk() takes 1 positional argument but 2 were given

我尝试了许多修复方法，但都是徒劳的。

另外，我希望机器人只接受最初通过命令请求石头剪刀布游戏的用户（换句话说，消息的作者）的输入，但我不确定如何实现，我试过了，但是没有用。

我该如何解决这个问题？

reaction_add 给出了一个反应和用户的元组，因此在chk 函数中，您需要同时拥有反应和用户。您还应该在chk 函数中使用and user == ctx.author 以确保用户相同。

@client.command(aliases = ["rock_paper_scissors","rps"])
async def _rps(ctx):    #rps is short for rock, paper, scissor
    emojis = ['✊', '?️', '✌️']
    
    embedVar = discord.Embed(title="CHOOSE YOUR WEAPON!",description = "Choose between rock, paper, or scissors, {}." . format(ctx.author.mention), color = 0xff9900)
    embedVar.add_field(name=":fist: ROCK", value="React with :fist: emoji to choose rock.", inline = False)
    embedVar.add_field(name=":hand_splayed: PAPER", value="React with :hand_splayed: emoji to choose paper.", inline = False)
    embedVar.add_field(name=":v: SCISSORS", value="React with :v: emoji to choose scissors.", inline = False)
    emb = await ctx.send(embed = embedVar)

    for emoji in emojis:
        await emb.add_reaction(emoji)

    def chk(reaction, user):
        return reaction.emb == emb and reaction.channel == ctx.channel and user == ctx.author
    
    react, user = await client.wait_for('reaction_add', check=chk)

    if react == '✊':
        await ctx.send("You chose rock!")
    elif react == '?️':
        await ctx.send("You chose paper!")
    elif react == '✌️':
        await ctx.send("You chose scissors!")
