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.
- 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.
In contrast, this is what reone offers:
- Written in C++ – potentially faster than Unity (C#) and JavaScript implementations.
- Modern codebase – C++14, OpenGL 3.3, no legacy code (e.g., multiple rendering paths in xoreos).
- KotOR and TSL only, unlike xoreos, which aims to reimplement all of Aurora Engine games.
