您如何制作一个机器人，在几秒钟后，在Discord.py中删除了受欢迎的嵌入并删除嵌入的嵌入

Question

这是我的代码，但似乎不起作用。我很抱歉，但我仍然是新手，但是，我非常感谢您的帮助和批评者。

import discord
from discord.ext import commands
client = commands.Bot(command_prefix=prefix,
                      intents=discord.Intents.all())

@client.event
async def on_message_join(member):
    channel = client.get_channel(channelid)
    count = member.guild.member_count
    embed=discord.Embed(title=f"Welcome to {member.guild.name}", description=f"Hello there {member.name}!", footer=count) 
    embed.set_thumbnail(url=member.avatar_url) 

    await channel.send(embed=embed)
    time.sleep(5)
    message.delete(embed)

Answer 1

正确的不符合事件是抓住一个人加入您的不和谐的是：

async def on_member_join(member: discord.Member):

而不是on_message_join

轻松删除您可以首先使其成为字符串的消息：

msg = await channel.send(embed=embed)

然后获取ID：然后获取它：

msg_id = msg.id

然后删除它：

msg_todel = await channel.fetch_message(int(msg_id))

将其删除：

await msg_todel.delete()

Answer 2

只需使用delete_after =秒，这是您想要的

import discord
from discord.ext import commands
client = commands.Bot(command_prefix=prefix,
                      intents=discord.Intents.all())

@client.event
async def on_message_join(member):
    channel = client.get_channel(channelid)
    count = member.guild.member_count
    embed=discord.Embed(title=f"Welcome to {member.guild.name}", description=f"Hello there {member.name}!", footer=count) 
    embed.set_thumbnail(url=member.avatar_url) 

    await channel.send(embed=embed, delete_after=5)

Answer 3

根据，您可以在5秒后编辑消息对象，然后将新的嵌入参数设置为无，这似乎是您在这里追求的。

以下是您可以更改代码执行此操作的方式。

import discord
import asyncio # You will need to import this as well
from discord.ext import commands
client = commands.Bot(command_prefix=prefix,
                      intents=discord.Intents.all())

@client.event
async def on_message_join(member):
    channel = client.get_channel(channelid)
    count = member.guild.member_count
    embed=discord.Embed(title=f"Welcome to {member.guild.name}", description=f"Hello there {member.name}!", footer=count) 
    embed.set_thumbnail(url=member.avatar_url) 

    message_object = await channel.send(embed=embed) # You can save the message sent by attaching it to a variable. You don't need to send more calls to refetch it.
    
    '''
    time.sleep(5) <--- You should not use time.sleep() as it will stop your entire bot from doing anything else during these 5 seconds.

    Use asyncio.sleep() as a better alternative. Does the same thing as time.sleep() but other functions of your bot will still function, this is called a  blocking function.
    '''

    asyncio.sleep(5)
    
    await message_object.edit(embed = None)

除非您要删除整个消息，否则您只需使用delete_after即可获得此消息。

import discord
from discord.ext import commands
client = commands.Bot(command_prefix=prefix,
                      intents=discord.Intents.all())

@client.event
async def on_message_join(member):
    channel = client.get_channel(channelid)
    count = member.guild.member_count
    embed=discord.Embed(title=f"Welcome to {member.guild.name}", description=f"Hello there {member.name}!", footer=count) 
    embed.set_thumbnail(url=member.avatar_url) 

    await channel.send(embed=embed, delete_after = 5) # Just add this parameter at the end.
