# Indigo

Indigo is a game engine written in Scala for functional programmers. It allows game developers to build games using a set of purely functional APIs that are focused on productivity and testing.

Indigo is built entirely on Scala.js + WebGL, but it's sbt and Mill plugins will export games for web, desktop (via Electron), and mobile (via Cordova). Hypothetically consoles could also be supported.

Documentation can be found on [indigoengine.io](https://indigoengine.io).

## Thank you, to our sponsors! 💜

Thank you to all our wonderful sponsors, and particularly to [dedipresta](https://www.dedipresta.com/) for their generous support.

If you'd like to help advance our work, we are ever grateful for all forms of contribution, either by volunteering time or [financial backing](https://github.com/sponsors/PurpleKingdomGames?o=esb). 

## Full local build and test instructions

### Using Nix

The root of the project contains a very very simple `flake.nix` file that, if you have nix installed and flakes enabled, will give you all the tools you need to build Indigo by running `nix develop` in the root directory.

### Build requirements

You will need:

- Mill
- SBT
- JDK (Update: 8 works, 17 is used in Indigo's development)

### Running the build

On Mac / Linux, from the repo root to do a full build and test:

```bash
bash build.sh
```

On Windows, open up powershell and run:

```powershell
& build.ps1
```

There is also another script which is a bit faster since it doesn't build the examples or demos.

```bash
bash localpublish.sh
```

## Software requirements for running games

The list above covers the software needed to build Indigo itself, but to run a game you may also need:

- NPM and/or Yarn
- NodeJS
- Electron
- An http server that will serve static from a directory (suggestions: `http-server` via npm, or Python's `SimpleHTTPServer`)
- A frontend packaging tool such as Parcel.js
