A simple quiz bot template. Participants have to answer all questions correctly to succeed.

commands are structured like sphinx.scope.option [...arg]. Replace "sphinx" with the username of the Discord bot account used. All commands require the user to have the ADMINISTRATOR permission, as all implemented commands reset and debug values.

• sphinx.setup Post the quiz message (can be in a locked channel)
• sphinx.reset.cooldown <userid> Reset the cooldown for the supplied user
• sphinx.reset.level <userid> Reset the level for the supplied user
• sphinx.check <userid> Display the user's current colldown, level and next backoff time
• sphinx.reload Reload quiz questions (run after changing ./questions folder content)
• sphinx.debug.backoff Display the Backoff table and function as seen above

If supplied with the key .env key QUIZ_ROLE the application will add the specified role to users successfully taking the quiz and check for it to already be present before allowing the quiz to start. This feature is optional (remove the key from .env to disable).

Questions are supplied as a .toml file (the filename is arbitrary and can be descriptive) to the ./questions folder, following the following format:

# unique ID
id = "1"
# correct choice value (question answer)
correct = "A"

# dropdown choices
choices = [
	{ value = "A", description = "Option A (this is correct)" },
	{ value = "B", description = "Option B" },
	{ value = "C", description = "Option C" }
]

# (optional) description to display above the codeblock
description = """
Pick
A\
"""

# (optional) code to display in a codeblock
code = """
function hello() {
	console.log("Hello World")
}
"""
# (optional) language to use for the codeblock highlight
codelanguage = "js"

Note that the id key value needs to be unique between all questions, else a later entry will overwrite the previous with the same id.

The file constants.ts holds the configurable user-facing messages, responses, constants, symbols, and emojis used in the application.

The default backoff function is

function backoffInMs(level: number): number {
	return (2 ** level / 4) * 60 * 60 * 1_000;
}

and results in the following values:

Lv: 0 | Backoff: 15m
Lv: 1 | Backoff: 30m
Lv: 2 | Backoff: 1h
Lv: 3 | Backoff: 2h
Lv: 4 | Backoff: 4h
Lv: 5 | Backoff: 8h
Lv: 6 | Backoff: 16h
Lv: 7 | Backoff: 1d
Lv: 8 | Backoff: 3d
Lv: 9 | Backoff: 5d

After the first attempt, a user will have to wait for 15 minutes, 30 minutes after the second, etc. (note that the return value, as suggested by the function name, should be wait time in milliseconds). Users gain a level as soon as the quiz starts to prevent aborting without consequence.

Should a user reach MAX_LVL their level is reset (by default 9).

Sphinx can run as a standard node process with

npm run build
npm run start

Alternatively, you can set up a docker 🐋 container with docker-compose up.

Note that in either case restarting the application will reset the level and cooldown of every involved user and reload all questions.
