python - discord.py-rewrite wait_for() 取消

Question

我正在制作一个带有重写的不和谐机器人，当命令运行时，事件必须完成，但是如果我想执行另一个命令，我不能因为前一个命令还没有完成，它会发送其他消息，我怎么能停止那？

@client.event
async def on_message(message):
    def check(m):
        return m.channel == message.channel and m.author != client.user

    if message.content.startswith("!order"):
        channel = message.author
        await channel.send("in game name")
        in_game_name = await client.wait_for('message', check=check)

        await channel.send("in game ID")
        in_game_ID = await client.wait_for('message', check=check)

        await channel.send("cargo type")
        cargo_type = await client.wait_for('message', check=check)

        await channel.send("cargo limit")
        cargo_limit = await client.wait_for('message', check=check)

        await channel.send("storage")
        storage = await client.wait_for('message', check=check)

        await channel.send("priority")
        priority = await client.wait_for('message', check=check)

如果它看到某个单词，您可以在检查中引发异常。在这里，如果机器人看到消息CANCEL，它将取消命令：

@client.event
async def on_message(message):
    def check(m):
        if m.channel == message.channel and m.content == "CANCEL":
            raise ValueError("Cancelled command")
        return m.channel == message.channel and m.author != client.user

    if message.content.startswith("!order"):
        channel = message.author
        await channel.send("in game name")
        in_game_name = await client.wait_for('message', check=check)
