A bot which provides a Trivia game for [Discord](https://discordapp.com/).

### Adding to a server
You can either self-host trivia-bot, or use the hosted version.

To invite the bot to your server use [this invite link](https://discordapp.com/oauth2/authorize?client_id=199657080083316737&scope=bot).
It requires no special permissions at this time (only read/write to channels).


### Installation
[Releases](https://github.com/jackb-p/trivia-bot/releases) are available for tagged versions. These are compiled on Ubuntu by Travis CI. To run on other systems you will need to compile yourself - a CMake configuration is included. Windows releases will happen one day.

If you want to install a version for which a release does not exist, you will also have to compile manually. Compilation instructions are available for Linux below.


### Running
To run simply execute the program: `./TriviaBot`

If you do not want to be prompted for your token every launch, provide it as an argument: `./TriviaBot {TOKEN}`

### Trivia Questions
Questions are obtained from [trivia-db on Sourceforge](https://sourceforge.net/projects/triviadb/).

To parse the `.txt` question files, place them in `/data_management/questions/` then run `LoadDB.cpp`. 
You need to create the database first. Use the included schema and create the database as `/bot/db/trivia.db`.

LoadDB.cpp takes some time to execute.


### Commands
`` `trivia`` is the base command.

| Argument | Description |
| --- | --- |
| `questions` `interval` | Where `questions` and `interval` are integers. Makes the game last `questions` number of questions, optionally sets the time interval between hints to `interval` seconds. | 
| stop | Stops the trivia game currently in the channel the message is sent from, if there is one. |
| help | Prints a help list, similar to this table. |
