Answer 1

Discord.py（重写）如何使用 on_message 事件获得冷却时间？我建议您查看这篇文章。

Answer 2

async def create_embed(self, ctx, err):&nbsp; &nbsp; &nbsp; &nbsp; embed = discord.Embed(title=f"Error Caught!",color=discord.Colour.red())&nbsp; &nbsp; &nbsp; &nbsp; embed.add_field(name=f"Info on the error.", value=f"{err}")&nbsp; &nbsp; &nbsp; &nbsp; embed.set_thumbnail(url=self.bot.user.avatar_url_as(static_format="png"))&nbsp; &nbsp; &nbsp; &nbsp; message_cooldown = commands.CooldownMapping.from_cooldown(1.0, 60.0, commands.BucketType.user)&nbsp; &nbsp; &nbsp; &nbsp; bucket = message_cooldown.get_bucket(ctx.message)&nbsp; &nbsp; &nbsp; &nbsp; retry_after = bucket.update_rate_limit()&nbsp; &nbsp; &nbsp; &nbsp; if retry_after:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return&nbsp; &nbsp; &nbsp; &nbsp; else:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; await ctx.send(embed=embed)这是一个很好的例子，它在函数中创建嵌入，使代码更干净，以便捕获错误，并确保它不会被冷却映射垃圾邮件。
