First, familiarize yourself with the Discord Developer Portal. You'll need to create an application for your bot and set it up. There are plenty of tutorials online on how to accomplish this, so I won't get in to it here.
This bot requires python3, at least version 3.9, but I recommend the latest.
After you have a bot set up, download the files in this repository. This bot relies a lot on third-party libraries, so you'll need to install those first. The requirements file lists all the python modules you'll need, and I recommend reviewing it so you don't install anything you don't want. You can use pip to install this list automagically using pip -r requirements.txt.
Once you have all the requirements installed, you need to specify at least the Discord token for your application in the .env file. Replace [Your Discord Token Here] with your actual token from the Discord Developer Portal.
Note that there are various other tokens required to get the full functionality of the bot. Refer to the .env file to see what you need. However, to get the bot started, you only need the Discord token, and the modules that require the others will stay un-loaded.
Finally, check the onebot_config.py file for configuration options. You can leave them set to the defaults, and the bot will work fine. But I really suggest reviewing them to customize your bot experience!
You are now ready to start your bot. Use your python interpreter to start the bot by running the onebot.py file. The bot is designed to be run in the background as a service, so you can start it headless and check the /log directory for output. Your bot should be up and running!
/info - show a simple information display for the bot, which includes useful links.
/google - an "I'm Feeling Lucky" search for the specified keywords. Works great for YouTube too! Try /google yt keyboard cat.
/image - a Google image search (SafeSearch enabled!). You can also use this without keywords for completely random images.
/gif - a random GIF search. Retrieves a random gif with the specified keyword, or, if no keyword is specified, a totally random GIF!
/ud - search Urban Dictionary for the most popular definition of the specified keyword. Supports Word of the Day.
/define - search Wiktionary for a definition. Supports any language -- use the language parameter to specify.
Related: /etym
/etym - Display the full etymology of a word from Wiktionary. Supports the language parameter to specify any language.
/quote - Retrieve your favorite quotes from the server. Retrieve them later using their ID, or just use the command by itself for a random quote.
/quoteadd - Add a new quote to your quote database!
/quoteremove - Remove a quote from the quote database. Requires Manage Server permissions to use.
/quotestats - Show stats from your /quote database. See the top 10 and bottom 10 quotes, or use the quote ID parameter to see detailed stats for a specific quote.
/weather - Retrieves the weather for a specific location. Allows you to set your default location for quicker future use by using the setdefault parameter.
/moon - Tells you if the moon is waxing or waning.
/joke - Retrieves a random dad joke. Supports searching by keyword.
/emote - display a large, upscaled emote for the custom server emoji that you specify.
It's really easy. First, decide on a name for your module. This isn't important and doesn't have to match the name of the slash command you want to make. Create a folder in the modules folder with the name of your module, then create a python file inside that folder with the same name.
For example, if I wanted to make a module called Foo, I'd make a modules/foo folder and inside that folder is foo.py.
Finally, I would add the module foo to the file onebot_config.py under the ONEBOT_MODULES setting to tell onebot to load my new foo module.
Below is a template for a simple module that sends a message to the channel.
Example foo.py:
import nextcord
from nextcord.ext import commands
class FooCog(commands.Cog):
def __init__(self, bot):
self.bot = bot
@nextcord.slash_command(
name="foo",
description='Sends the message "foo foo foo!" as a response.',
)
async def foo(self, interaction: nextcord.Interaction):
await interaction.send("foo foo foo!")
def setup(bot):
bot.add_cog(FooCog(bot))This can be considered a module skeleton, and nearly all modules will follow this format.
Onebot uses the nextcord library, so to do anything more complicated I recommend checking our their excellent documentation.
Onebot contains utility modules that handle storing and retrieving data from a database, and a few other tasks.
You can access the database utility functions by using self.bot.db_utils in your module. db_utils contains the following functions:
list_db()
Returns a list of database files available to onebot.
create_db(server_id)
Creates a new database for the specified server id. NOTE: This happens automatically if a db doesn't exist, so you shouldn't have to call this function manually.
delete_db(server_id)
Deletes the database for the specified server id.
get_db_connection(server_id)
Returns an sqlite3 Connection object.
get_server_pref(server_id, preference)
Returns the stored value for the specified String preference for the specified server. Can be used to read server-wide preferences that are set by a server user.
set_server_pref(server_id, preference, value)
Stores a value for the specified String preference for the specified server. Used to store server-wide preferences that a set using a slash command.
clear_server_pref(server_id, preference)
Clears the specified String preference for the specified server by removing it from the database.
get_member_pref(server_id, member_id, preference)
Retrieves the user-specific stored value for the specified String preference for the specified server. Used to read member-specific preferences (for example, a user's default weather location that they saved earlier).
set_member_pref(server_id, member_id, preference, value)
Stores the user-specific value for the specified String preference for the specified server. Used to store member-specific preferences (like the aforementioned default weather location).
You can use these db_utils to read/write from an sqlite3 database easily.
Similarly, self.bot.utils contains more utility features, and these are non-database related. self.bot.utils contains the following functions:
get_random_word(bot)
Returns a String random word. Used to retrieve random gifs and images for /gif and /image. You can use this in your own modules by passing the bot context object to this function.
Below is an example ReadWrite module that demonstrates how to use the built-in database functions to store and retrieve a user string.
Example readwrite.py:
import nextcord
from nextcord.ext import commands
class ReadWriteCog(commands.Cog):
def __init__(self, bot):
self.bot = bot
@nextcord.slash_command(
name="read",
description='Sends the stored user string.',
)
async def read(self, interaction: nextcord.Interaction):
stored_data = self.bot.db_utils.get_member_pref(interaction.guild_id, interaction.user.id, 'readwritecog.data')
await interaction.send(stored_data)
@nextcord.slash_command(
name="write",
description='Stores the string that the user specifies.',
)
async def write(self, interaction: nextcord.Interaction, data_to_store: str = SlashOption(
name="data to store",
description="Type what you want to store in the database",
required=True,
),):
self.bot.db_utils.set_member_pref(interaction.guild_id, interaction.user.id, 'readwritecog.data', data_to_store)
await interaction.send("Stored your data in the database! Use /read to retrieve it.")
def setup(bot):
bot.add_cog(ReadWriteCog(bot))If you need functionality that extends beyond one-row storage and retrieval, you can use bot.db_utils.get_db_connection(server_id) to get your own sqlite3 Connection object, and do anything you want!
