discord.py 的 cog 任务

Question

这应该每 15 分钟在频道中发送一条消息。 由于某种原因，它不起作用。它也没有显示任何错误。有人可以帮我解决这个问题吗？

import time

from discord.ext import commands

message = 'choose roles from <#728984187041742888>'
channel_id = 742227160944869437  # the channel id (right click on the channel to get it)
time_spacing = 15*60  # s : 15min


class auto(commands.Cog):
    def __init__(self, bot):
        self.bot = bot


    @commands.Cog.listener()
    async def spamm(self, ctx):
        while True:
            time.sleep(time_spacing)
            await ctx.get_channel(channel_id).send(message)


    @commands.Cog.listener()
    async def on_ready(self):
        print(f'Sp4mm3r {self.bot.user} has connected to Discord!')
        print('Sending message :', message, 'every', time_spacing, 'seconds')


def setup(bot):
    bot.add_cog(auto(bot))

---------修正版------------ 认为问题是我没有开始任务，并且 time.sleep 不应该在那里使用。

from discord.ext import tasks
from discord.ext import commands


time = 30*60


class Automessager(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.message = 'Choose roles from <#728984187041742888>'
        self.channel1 = 725550664561983519
        self.text.start()
  

    @tasks.loop(seconds=time)
    async def text(self):
        try:
            channel = self.bot.get_channel(self.channel1)
            await channel.send(self.message)
        except Exception as e:
            print(e)


    @commands.Cog.listener()
    async def on_ready(self):
        print(f'{self.bot.user} has connected to Discord!')
        print(f'Sending message: {self.message} every {time} seconds')


def setup(bot):
    bot.add_cog(Automessager(bot))

Answer 1

您的代码中有两个错误：

• get_channel() 是 commands.Bot 方法，而不是 discord.Context 方法。
• 如果您使用time.sleep() 等待 15 分钟，它将冻结您的整个 cog。

要制作循环，您可以使用 task.loop()，而不是使用 cog 侦听器：

from discord.ext import task
from discord.ext import commands


class auto(commands.Cog):
    def __init__(self, bot):
        self.bot = bot
        self.message = 'Choose roles from <#728984187041742888>'
        self.channel_id = 742227160944869437
        self.minutes = 15

    @task.loop(minutes=self.minutes)
    async def spamm(self, ctx):
         channel = self.bot.get_channel(self.channel_id)
         await channel.send(self.message)

    @commands.Cog.listener()
    async def on_ready(self):
        print(f'Sp4mm3r {self.bot.user} has connected to Discord!')
        print(f'Sending message: {self.message} every {self.minutes} minutes')


def setup(bot):
    bot.add_cog(auto(bot))

PS：我已将channel_id、message 和minutes 设置为类变量。你也不需要使用time.sleep()。
