discord bot 用户反应

Question

So I am trying to make my personal "splashbot" for my discord server. This is one of the commands that it should do. The problem is that I don't know how to check if the player choose one of the reactions. I tried some things out and here is the code:

@client.command(aliases=['paidsplash'])
async def splash(ctx):
    message = await ctx.send('Are you sure you want to do a paid splash?')
    emoji1 = '✅'
    await message.add_reaction(emoji1)
    emoji2 = '❌'
    await message.add_reaction(emoji2)
    await ctx.message.delete()
    client.wait_for("reaction.users()=='✅'",  timeout=10.0) #reaction.users()?
    await ctx.send('yes')

Basically the player types '*splash', the bots removes that and asks the question + adds those 2 reactions on it. Then the player must pick a reaction. They will be added to a queue if ✅ but I haven't come to that part... Preferable just copy and edit to code in your answer, so I can see what is wrong, I learn the fastest that way

Answer 1

The client.wait_for code is incorrect. You're supposed to define a check function first, then pass that through to the wait_for function so that it can check for a reaction.

This is some sample code from the discord.py documentation ( https://discordpy.readthedocs.io/en/latest/api.html#discord.Client.wait_for ) edited to work for your situation. Essentially, it's just the same thing as the example code but waits for a reaction not done by the bot (or the author of the message in the code)

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

        try:
            reaction, user = await client.wait_for('reaction_add', timeout=60.0, check=check)
        except asyncio.TimeoutError:
            await channel.send('👎')
        else:
            await channel.send('👍')
