当有人对它做出反应时重复一个功能

Question

试图做到这一点，以便当有人使用表情符号对消息做出反应时，它会重复该功能 - 尝试在批处理文件中找到类似于 goto 的内容

例如：我输入$randomcar

Bot 发送：Your chosen car is the bmw! 和 ????反应。当我按下它时，它会再次重复该功能：

Bot 发送 Your chosen car is the audi! 和 ????我可以再次按下以重复该功能的反应

@bot.command()
async def randomcar(ctx):
 while True:
   msg = await ctx.send("Your chosen car is the {}!".format(random.choice(cars)))
   await msg.add_reaction("????")
   async def on_raw_reaction_add(payload: discord.RawReactionActionEvent):
     if msg.reaction=="????" and msg.id:
      continue

我收到错误：

Syntax error: continue not properly in loop

谢谢

这可以使用递归来完成：

@bot.command()
async def randomcar(ctx):
    msg = await ctx.send("Your chosen car is the {}!".format(random.choice(cars)))
    # you may need to check if your bot has the "add reactions" permission
    await msg.add_reaction("?")
    await bot.wait_for(
        "reaction_add",
        check=lambda reaction, user: user == ctx.author and reaction.emoji == "?" and reaction.message == msg,
    )
    await randomcar(ctx)

您还可以添加timeout，之后它将停止重复：

@bot.command()
async def randomcar(ctx):
    msg = await ctx.send("Your chosen car is the {}!".format(random.choice(cars)))
    await msg.add_reaction("?")
    try:
        await bot.wait_for(
            "reaction_add",
            timeout=10.0,  # 10 second timeout
            check=lambda reaction, user: user == ctx.author and reaction.emoji == "?" and reaction.message == msg,
        )
    except asyncio.TimeoutError:
        try:
            await msg.remove_reaction("?", bot.user)
        except discord.NotFound:
            pass
    else:
        await randomcar(ctx)
