Discord.py Extract user from reaction

I am writing a feature in my bot which allows 2 users to duel each other, and the way it works is that the bot sends a message telling everyone to get ready and then after a random number of seconds pass the bot reactions with a certain emoji on the message and the first person in the duel reacts to the message wins. It a simple I idea but I can't figure out how to see if a certain user has reacted to the message. My question is - is this possible or do I have to figure out another approach to this?

This is definitely possible with wait_for which is documented here. The wait_for function waits for any specified event listed in the event reference.

It takes in three parameters Event, Check (optional) and timeout(optional)

there are examples in the documentation but for you it would be something like:

bot = commands.Bot(command_prefix='.', case_insensitive=True)

@bot.command()
async def game(ctx):
    # Whatever you want here
    msg = await ctx.send("React first to win")
    await msg.add_reaction('👍')

    def check(reaction, user):
        return str(reaction.emoji) == '👍' and user != bot.user

    try:
        # Timeout parameter is optional but sometimes can be useful
        reaction, user = await bot.wait_for('reaction_add', timeout=30, check=check)
        
        # Will wait until a user reacts with the specified checks then continue on with the code
        await ctx.send(f"Congratulations {user.name} you won!")
    except asyncio.TimeoutError:

        # when wait_for reaches specified timeout duration (in this example it is 30 seconds)
        await ctx.send("You ran out of time!")

The Timeout=30 parameter is 100% optional you can remove it so it would wait forever (or until you turn your bot off). The check parameter is also optional.

P.S. I am assuming you are using python 3 or more hence the F-strings

Yes, that's possible for sure, there are multiple ways for doing this, I never tried it before since I didn't create any bots with reaction things but that should work.

using on_reaction_add

@client.event
async def on_reaction_add(reaction, user):
    channel = client.get_channel('123')
    if reaction.message.channel.id != channel.id:
        return
    else:
        if reaction.emoji == "✅":
            #Do something
            print(user.name)
            print(user.discriminator)
            await channel.send(f"{user} has won the game")

Make sure to take a look at the on_reaction_add documentation and the reaction one
