Current Status

Unravel Engine is currently under active development and is not yet production-ready. Contributions, feature requests, and feedback are highly encouraged to shape its evolution.

Getting Started

Download and install Mono from Mono Project On linux it is recommended to install the full mono-complete package if you want full experience with the IDE

Editor

You can download binaries for Windows and Linux from Releases

There is also a DemoProject available with the binaries.

The Editor uses Visual Studio Code or any of its forks like (Cursor, etc) for code editing.

You can double click on a script from the editor and it will open it with the detected vscode.

When opening a file it should prompt yout to install the necessary extensions. Do NOT skip them.

Building

The project uses CMake as a build system so it is recommended to use that workflow in your IDE.

git clone https://github.com/unravel-dev/UnravelEngine.git
cd UnravelEngine
git submodule update --init --recursive

mkdir build
cd build
cmake ..

For Linux you can see the workflow file for the necessary packages Linux
