python - 如何在 Discord 中更新每条新消息的 message.content ？

Question

这个问题措辞很糟糕，但是对于我正在制作的一个不和谐机器人，它会在 message.content 中查找“s!rps”，如果在聊天中发送“s!rps”，它会要求 Rock, Paper ，或剪刀。我希望它更新每条新消息的消息内容，但 message.content 保持为 s!rps 并创建无限循环。如何更新每条新消息的 message.content？

if "s!rps" in message.content:
        MAI = message.author.id
        msg = "Do you pick Rock, Paper, or Scissors?".format(message)
        await client.send_message(message.channel, msg)
        while True:
            cr = random.randint(1,3)
            if message.content.startswith("Rock"):
                if message.author.id == MAI:
                    choice = 1
                    break
            elif message.content.startswith("Paper"):
                if message.author.id == MAI:
                    choice = 2
                    break
            elif message.content.startswith("Scissors"):
                if message.author.id == MAI:
                    choice = 3
                    break
            elif message.content.startswith("rock"):
                if message.author.id == MAI:
                    choice = 1
                    break
            elif message.content.startswith("paper"):
                if message.author.id == MAI:
                    choice = 2
                    break
            elif message.content.startswith("scissors"):
                if message.author.id == MAI:
                    choice = 3
                    break
            else:
                if message.author.id == MAI:
                    if message.content != "s!rps":
                        msg = ("\"%s\" isn't a valid input." % message.content).format(message)
                        await client.send_message(message.channel,msg)    
        if choice == "Rock":
            choiceNum = 1
        if choice == "Paper":
            choiceNum = "2"
        if choice == 3:
            choiceWord = ""
        if cr == 1:
            crWord = "Rock"
        if cr == 2:
            crWord = "Paper"
        if cr == 3:
            crWord = "Scissors"
        if (cr-choice+5)%3 == 1:
            msg = ("You picked %s, I picked %s, you win!" % (choiceWord, crWord)).format(message)
            await client.send_message(message.channel, msg)
        if (cr-choice+5)%3 == 2:
            msg = ("You picked %s, I picked %s, I win!" % (choiceWord, crWord)).format(message)
            await client.send_message(message.channel, msg)
        if cr == choice:
            msg = ("We both picked %s, it's a tie." % choiceWord).format(message)
            await client.send_message(message.channel, msg)

您的消息内容在整个过程中都是固定的，您永远不会更新或等待新消息。此外，该循环可能会完全阻塞您的工作流程!删除 while 循环，改用 Client.wait_for_message(如果要重写，则使用 Client.wait_for)。

我将按如下方式执行此操作，在事件内部定义一个内部函数，可在等待特定消息时用作检查:

def check(m):
    answers = ["rock", "paper", "scissors"]
    if any(answer == m.content.lower() for answer in answers):
        return True
    else:
        client.send_message(m.channel, "{0.content} is not a viable option".format(m))
        return False

然后，摆脱 while 循环，即将代码修改为:

    MAI = message.author.id
    msg = "Do you pick Rock, Paper, or Scissors?".format(message)
    await client.send_message(message.channel, msg)
    answer_msg = await client.wait_for_message(author = MAI, check = check)
    answer = answer_msg.content.lower()

    if answer == "rock":
        choice = 1
    elif answer == "scissors": 
    .....

请注意，wait_for_message 有一个author 参数，确保消息作者确实是您想要的作者，这意味着您的if message.author.id == MAI 将被考虑在内。而且现在不区分大小写。
