Discord.py: Create an 'on_message' Function for Fun Chat Interactions

Sure! Here's an example of an on_message function using discord.py that responds to certain messages with a fun reaction:

import discord
from discord.ext import commands

bot = commands.Bot(command_prefix='!')

@bot.event
async def on_message(message):
    # Ignore messages from the bot itself to avoid infinite loops
    if message.author == bot.user:
        return

    # Check if the message content matches a specific trigger
    if message.content.lower().startswith('hello'):
        await message.channel.send('Hello there!')
    elif message.content.lower().startswith('goodbye'):
        await message.channel.send('Goodbye!')
    elif message.content.lower().startswith('!react'):
        await message.add_reaction('👍')
        await message.add_reaction('👎')

    # Let the bot process commands as well
    await bot.process_commands(message)

# Run the bot
bot.run('YOUR_BOT_TOKEN')

In this example, the bot responds with different messages based on the triggers 'hello' and 'goodbye'. Additionally, if a message starts with !react, the bot will add a thumbs-up and thumbs-down reaction to that message.

Remember to replace 'YOUR_BOT_TOKEN' with your actual bot token.
