reone

reone is a free and open source game engine, capable of running Star Wars: Knights of the Old Republic and its sequel, The Sith Lords. We aim to provide an engine that is flexible and modern, and can be used to:

• Play KotOR and TSL from beginning to end
• Create mods that drastically change the gameplay or improve the visuals

Currently, the most fundamental engine subsystems are already implemented. Actual gameplay, however, is very limited. See project gallery and roadmap in the Wiki.

Installation

Those wishing to test reone, can either download a prebuilt executable from the releases page, or build it from source. Building it requires a modern C++ compiler and a set of free and open source libraries. See detailed instructions for your operating system here.

To run a game using reone, you must legally own it – we do not endorse piracy. Nowadays both games can be downloaded from Steam or GOG.com. Keep in mind that reone is tested against vanilla versions of the games – mod support is not guaranteed.

Install Visual C++ Redistributable to run prebuilt Windows executables.

Usage

Specify a game path to run the game, e.g. reone --game C:\swkotor

Controls:

• Use WASD keys to move around
• Click on doors to open them

Configuration

reone can be configured from either a command line or a configuration file. Configuration file, named "reone.cfg", must be located in the current directory. See complete list of options here.

Contribution

reone is open to potential contributors. Contact me at vkremianskii@gmail.com if you're interested in taking a particular task from the roadmap. For an overview of the project architecture, take a look at the development page in the Wiki.

Similar Projects

reone is not the only project aiming to reimplement the Odyssey engine – there are at least four alternatives:

• xoreos – a more ambitious and a more established project, which I had contributed to and use alot as a reference. It is, however, not very active anymore, and I find it to be too complex and unoptimized for my taste.
• KotOR.js – a fascinating JavaScript-based remake.
• KotOR-Unity – a Unity-based reimplementation.
• The Northern Lights by Lachlan O'Neill – another Unity-based reimplementation and a level editor.
