Diceless

Diceless is a dice roller with a small toolkit for visualizing the probabilities of rolls. It is what powers diceless.io. It can be used when dice are not readily available, or if you want more feedback about the statistics of a given roll. For a more in-depth toolkit into just the probability distributions, I recommend the excellent tool at anydice.com.

Diceless is designed for speed of use. You can write a dice expression such as '2d6+3d8+4' and press enter. It will immediately roll the dice and add this expression to a quick roll history, so you can repeat that same roll easily.

Features

• Write a dice expression and roll it pressing enter.
• Previous expressions are shown as buttons for quick re-rolling.
• See quick stats about the roll: sum, average, highest, lowest, probability (at most, at least).
• See the detailed distribution graph for exactly this roll, at most and at least.
• Everything happens on the client; there is no backend. Collaborative features might change that in the future.

Install

Requirements

• Node.js (was developed using v8.11.3)

Run in development mode

To get started in development mode, clone this repository and cd into the directory. Then run:

npm install
npm start

This will expose diceless on port 3000. It should automatically open in a new browser tab.

Tests

If you want to run the test, you can do so by running (after running install):

npm test

Docker

There is also a dockerfile included. If you have docker installed, you can run:

npm run build-docker
docker run -it -p 3000:3000 diceless

This will expose diceless on port 3000. Navigate to http://localhost:3000/ to see it.

Possible improvements

• Complex logic (for example, roll 4d6 and discard the lowest)
• Special dice (Fate dice, dice with symbols, repeated sides, etc.)
• Shared session of dice rolling.
• Mobile version.

Roadmap

This is mainly a hobby project, and I have no idea whether it has any appeal to gamers, who generally appreciate the tactile experience of rolling actual dice. I thought it would be interesting to make, especially as I wanted to try out developing React with TypeScript.

If it matures to a state I consider useful enough, I will publish it to a public domain.

I only have the time to keep the development at low intensity. To speed up development and elevate the ambitions of the project, it would require collaborators.

Contributions

I accept pull requests after review, and the review will require that:

• The TS lint configuration is respected.
• Non-components / library classes are unit tested. I haven't quite figured out how to effectively unit test React components.
