discord.py重写|如何等待作者留言? [英] discord.py rewrite | How to wait for author message?

问题描述

我正在执行一条命令，等待用户回复该漫游器，但我希望该漫游器仅接受作者的回复.

I am making a command which waits for a user to reply to the bot, but I would like the bot to only accept the author's reply.

@client.command(name='numgame',
            brief='Guess a number between 1 and 100',
            pass_context=True)
async def numgame(context):
number = random.randint(1,100)
guess = 4
while guess != 0:
    await context.send('Pick a number between 1 and 100')
    msg = await client.wait_for('message', check=check, timeout=30)
    attempt = int(msg.content)
    if attempt > number:
        await context.send(str(guess) + ' guesses left...')
        await asyncio.sleep(1)
        await context.send('Try going lower')
        await asyncio.sleep(1)
        guess -= 1
    elif attempt < number:
        await context.send(str(guess) + ' guesses left...')
        await asyncio.sleep(1)
        await context.send('Try going higher')
        await asyncio.sleep(1)
        guess -=1
    elif attempt == number:
        await context.send('You guessed it! Good job!')
        break

我的问题是，任何人都可以响应选择号码"，而我只希望启动命令的人能够响应.

My issue is that anyone can respond to "Pick a number," whereas I would only like the person who started the command to be able to respond.

我不太确定尝试什么，但是我认为这可能与参数有关.不过，我不知道从哪里开始，因此不胜感激！多谢.

I am not too sure what to try, but I think it may have something to do with arguments. I have no idea where to begin, though, so a solution would be appreciated! Thanks a ton.

推荐答案

您需要重写您的 check ，以便它知道作者是谁.一种方法是使用闭包.假设您已有支票

You need rewrite your check so that it knows who the author is. One way of doing this is to use a closure. Let's say you have an existing check

def check(message):
    return message.content == "Hello"

您可以将其替换为一个函数，该函数会与您要检查注入的作者生成等效的检查函数

You can replace this with a function that generates equivalent check functions with the author you want to check for injected into them

def check(author):
    def inner_check(message):
        return message.author == author and message.content == "Hello"
    return inner_check

然后，您可以通过使用适当的参数调用外部支票来将内部支票传递给 wait_for :

Then you would pass the inner check to wait_for by calling the outer check with the appropriate argument:

msg = await client.wait_for('message', check=check(context.author), timeout=30)

请检查

def check(author):
    def inner_check(message): 
        if message.author != author:
            return False
        try: 
            int(message.content) 
            return True 
        except ValueError: 
            return False
    return inner_check
