Clojure in Unity

Arcadia

The integration of the Clojure Programming Language with the Unity 3D game engine.

Status

Arcadia is alpha-quality software, and shouldn't be used for anything important yet.

Primary work is done on the rapidly evolving develop branch. Use that for bleeding edge features.

Usage

The contents of the repository should be copied to a folder named Arcadia in any Unity project's Assets folder to enable Clojure. In the future, this will be available from the Asset Store. Once copied, you have access to the REPL and the Clojure compiler.

There's a screencast on getting set up here.

Download Zip File

1. Create a subfolder of your Assets folder named Arcadia
2. Download our zip file and extract its contents into Arcadia

Git Clone

cd path/to/unity/project/Assets
git clone https://github.com/arcadia-unity/Arcadia.git

Prerequisites

Before doing anything, Arcadia requires that Unity be set to run in the background and use the full .NET API

Run in Background

Click Edit > Project Settings > Player, then in the Inspector under Resolution and Presentation make sure Run In Background is checked.

.NET API

Click Edit > Project Settings > Player, then in the Inspector under Other Settings make sure Api Compatibility Level is set to .NET 2.0 and not .NET 2.0 Subset.

REPL

Arcadia ships with a simple networked REPL that is started automatically or from Clojure > REPL > Start. You can connect to this REPL using Clojure/Editor/repl-client.rb. This script is also the basis of our Sublime Text support (via SublimeREPL) and our Emacs support (via Inferior Lisp).

Clojure Components

You can write components in pure Clojure using our defcomponent form. To be recognized by Unity these must be saved in Clojure files, not just defined in the REPL.

Mailing List

The mailing list is here.

IRC

The IRC channel for Arcadia is #arcadiaunity on freenode, if we're online we're usually on the channel.

Name

This project was originally named "clojure-unity", but was changed to "Arcadia" to avoid infinging on Clojure's trademarks. It was suggested to us by @ztellman at a bar during StrangeLoop 2014, and we are eternally grateful.
