在我的不和谐机器人(python)上,我试图检测或更确切地说是检查命令中发送的消息:如果有人键入命令 $start,则该命令应在 while 循环中检查 $start 命令之后正在发送哪些消息。如果发送的消息是“加入”,则发送消息的用户应该被添加到列表中。我试图通过 on_message() 函数检测消息并将其保存在变量中,但它似乎不起作用,我认为我的代码没有多大意义,但我不知道如何正确实现它。

import discord
from discord.ext import commands
    
client = commands.Bot(command_prefix = "$")

@client.event
async def on_ready():
    print("started")

sentMsg = ""
users = []

@client.event
async def on_message(msg):
    if msg.author == client.user:
        return
    else:
        sentMsg = msg.content
        print(sentMsg)

@client.command()
async def start(ctx):
    print(sentMsg)
    await ctx.send("starting ...")
    users.append(ctx.author)
    while True:
        if sentMsg == "join":
            ctx.send("Joined!")
            sentMsg = ""

client.run(*token*)

我将 sentMsg 变量放在 VS-Code 的 Watch 部分,它总是说“不可用”,尽管它打印了正确的值。此外,当在 on_message() 中将鼠标悬停在它上面时,它会说:“sentMsg”未被访问 Pylance。任何人都可以改进我的代码,或者有人有更好的想法来实现这个吗?

我会很感激任何人的帮助

您可以使用 client.wait_for 让机器人检测消息,而不是使用 on_message 事件!

例如:

@client.command()
async def start(ctx):
    await ctx.send("starting ...")
        try:
            message = await client.wait_for('message', timeout=10, check=lambda m: m.author == ctx.author and m.channel == ctx.channel and ctx.content == "join") # You can set the timeout to 'None' 
            # if you don't want it to timeout (then you can also remove the 'asyncio.TimeoutError' except case 
            # (remember you have to have at least 1 except after a 'try'))

            # if you want the bot to cancel this if the message content is not 'join',
            # take the last statement from the check and put it here with an if
            
            # what you want to do after "join" message

        except asyncio.TimeoutError:
            await ctx.send('You failed to respond in time!')
            return
