如何让我的 Discord 机器人看起来像是在打字？

Question

我有一个运行 discord.py 的 Discord 机器人，当我使用帮助功能时，消息之间有时会有几秒钟的小延迟。当一个活生生的用户在 Discord 上打字时，它通常会显示 3 个交替阴影的小点，同时说 Example 正在打字。我怎样才能用我的机器人显示这个？ 我有一个现在不起作用的功能，即 和

async def balabala (ctx):
    async with ctx.typing():
        await message.channel.send(prefix + "random [Value 1] [Value 2]  -  Gives a random number between Value 1 and Value 2, inclusive")
    await ctx.send(prefix + "choose [Value 1] (Value 2) (Value 3) etc.  -  Chooses a random value from the list of values you provide") # what you want to do after typing    
@client.event
async def on_message(message):
    if message.content.lower() == prefix + "help":
        await message.channel.send("The prefix for this bot is " + prefix)
        await message.channel.send("Note: Do not actually enter [](required) or ()(Not required)")
        await message.channel.send(prefix + "help  -  Shows this message" )
        await message.channel.send("Hello  -  Gives a hello back, because you are so nice")
        await message.channel.send(prefix + "invite - Gives an invite to the bot, and Canary versions")
        
        await balabala()

出现的错误是

您将能够打开 Messageable 对象（例如 TextChannel、DMChannel）的上下文管理器并在其中执行您的任务。

我以asyncio.sleep() 为例延迟：

@bot.command()
async def hello(ctx):
    async with ctx.typing():
        await asyncio.sleep(2) # some tasks go here, the sleep is just for a delay
    await ctx.send(f"Hello, {ctx.author.mention}!") # what you want to do after typing

• Messageable.typing()
• asyncio.sleep()
• abc.Messageable
• commands.Context - async with typing() 在这里工作，因为它“实现了 Messageable ABC。”
