问题描述
我正在发出等待用户回复机器人的命令,但我希望机器人只接受作者的回复.
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一个数字",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.
我不太确定该尝试什么,但我认为这可能与争论有关.不过,我不知道从哪里开始,所以一个解决方案将不胜感激!非常感谢.
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
你需要重写你的 check 让它知道作者是谁.一种方法是使用闭包.假设您有一张现有的支票
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"
您可以将其替换为生成等效检查函数的函数,并将您要检查的作者注入其中
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检查,将内部检查传递给 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)
为了您的检查,这将是
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
