Elevator Saga

The elevator programming game

Play it now!

Or Run the unit tests

For developers/contributors: This project is not actively maintained. The repo is used to serve github pages so I would like to keep it as is. Feel free to fork and host your own versions of Elevator Saga! But I would like to keep the domain name with the original version of the game.

Python NiceGUI visualization

The Python-first interface visualizes both Python and Java strategies. It records simulation snapshots and replays elevators and passengers in the browser with Python-controlled NiceGUI elements.

python3 -m venv .venv
.venv/bin/pip install -r requirements-nicegui.txt
.venv/bin/python nicegui_app.py --port 8082

Open http://127.0.0.1:8082/. Python is the default language; Java visualization requires JDK 11 or newer. The interface includes challenge and language selection, strategy editing, play/pause, replay speed, progress, and live replay statistics.

Local multi-language mode

The local development server uses Python as the default strategy language and provides a language selector:

• Python is selected by default and runs headlessly through the Python port.
• JavaScript remains available with the original browser visualization.
• Java runs headlessly through the Java port and requires JDK 11 or newer.

Start the server from the repository root:

python3 multilang_server.py --port 8001

Then open http://127.0.0.1:8001/index.html. Python and Java strategies are arbitrary local programs and run with your user permissions; only execute code you trust.
