使用 discord.py,我可以从一段代码运行多个机器人,但我正在寻找一种将 cog 或扩展加载到多个机器人中的方法.对于一个测试用例,我有 bot.py,它处理加载 cog 和启动 bot,以及 cog.py,它是一个简单的 cog,它递增 1 到 a计数器

Using discord.py, I can run multiple bots from one piece of code, but I'm looking for a way to load a cog or extension into multiple bots. For a test case, I have bot.py, which handles loading the cog and starting the bot, and cog.py which is a simple cog that incrementally adds 1 to a counter

bot.py

from discord.ext import commands
import asyncio

client1 = commands.Bot(command_prefix='!')
client2 = commands.Bot(command_prefix='~')

client1.load_extension('cog')
client2.load_extension('cog')

@client1.event
async def on_ready():
    print('client1 ready')

@client1.command()
async def ping():
    await client1.say('Pong')

@client2.event
async def on_ready():
    print('client2 ready')

@client2.command()
async def ping():
    await client2.say('Pong')

loop = asyncio.get_event_loop()
loop.create_task(client1.start('TOKEN1'))
loop.create_task(client2.start('TOKEN2'))
loop.run_forever()

cog.py

from discord.ext import commands

class TestCog:

    def __init__(self, bot):
        self.bot = bot
        self.counter = 0

    @commands.command()
    async def add(self):
        self.counter += 1
        await self.bot.say('Counter is now %d' % self.counter)


def setup(bot):
    bot.add_cog(TestCog(bot))

使用 !ping 将使 client1 响应 Pong,而使用 ~ping 将使 client2 响应Pong,这是预期的行为.

Using !ping will make client1 respond with Pong, while using ~ping will make client2 respond with Pong, which is expected behaviour.

但是,只有一个机器人会同时响应 !add~add,计数器会随着任一命令而增加.这似乎取决于哪个机器人最后加载 cog.

However, only one of the bots will respond to both !add and ~add, with the counter increasing with either command. This seems dependent on which bot loads the cog last.

有没有办法让正确的机器人响应正确的命令,同时通过任一命令增加计数器?我知道我可以将它分成两个齿轮并将结果保存到一个文件中,但是是否可以在不将计数器保存到磁盘的情况下做到这一点?

Is there a way to have the correct bot respond to the correct command while also having the counter increase with either command? I know I can split it into two cogs and save the result to a file for example, but is it possible to do it without saving the counter to disk?

推荐答案

这是因为 @commands.command() 只加载了一次.因此,两个机器人共享相同的 Command 实例.您需要在实例级别添加命令,而不是通过 @commands.command() 装饰器.

This is due to the fact that @commands.command() is only loaded once. Therefore, both of the bots shared the same Command instance. What you need is to add the command on an instance level, and not by the @commands.command() decorator.

class TestCog:
    counter = 0

    def __init__(self, bot):
        self.bot = bot
        self.bot.add_command(commands.Command('add', self.add))

    async def add(self):
        TestCog.counter += 1
        await self.bot.say('Counter is now %d' % TestCog.counter)

或:

class TestCog:
    counter = 0

    def __init__(self, bot):
        self.bot = bot
        self.bot.command()(self.add)

    async def add(self):
        TestCog.counter += 1
        await self.bot.say('Counter is now %d' % TestCog.counter)

为了让两个机器人共享相同的属性.你想要的是类属性,而不是实例的.

In order to make both bots share the same attribute. You want class attribute, not instance's.
