Prologot is a GDExtension that integrates SWI-Prolog into Godot 4, enabling logic programming in your games. Use Prolog for AI decision-making, dialogue systems, rule engines, pathfinding, and more.
- SWI-Prolog integration via GDExtension.
- Interactive Prolog console in the Godot editor.
- Query execution with variable bindings.
- Dynamic fact assertion and retraction.
- Consult Prolog files or code strings.
- Knowledge base management.
- Type conversion between Prolog terms and Godot Variants.
You can see Use Cases for basic examples and quick start guide.
- Getting Started: Follow the Installation Guide to set everything up. The quick way to compile:
# Install dependencies (Linux example)
sudo apt-get install swi-prolog swi-prolog-nox pkg-config
pip install scons
# Clone and build
git clone https://github.com/yourusername/Prologot.git
cd Prologot
make GODOT_CPP=4.5 all- Try the Demo: Once built, run the Interactive Demo to see Prologot in action:
make run-demo-
Experiment in the Editor: After playing with the demos, fire up the Editor Console in Godot. It's like having a Prolog REPL right in your editor - perfect for tinkering and testing ideas. Once you've convinced yourself that Prolog is actually useful (we know, it's a hard sell), grab the hello_world_prologot.gd template and start building. Don't forget to check the API Reference when you need the details.

For Prolog Veterans: If you're already fluent in Prolog and wondering why we renamed everything, check out the Mapping between Prologot and traditional Prolog names. We promise it's not just to confuse you.
