openLegoLoco

Early Development — This is a one-man hobby project and is far from complete. Expect missing features, rough edges, and frequent breaking changes. Contributions and feedback are welcome, but please keep expectations in check.

An open-source recreation of LEGO Loco (1998), the LEGO train-building sandbox game, built with C++ and raylib.

Roadmap

The project is structured around 8 main milestones toward a first playable version.

Milestone	Status
1. Core Engine — grid, tiles, camera, world save/load	Done
2. User Interface — main menu, toy box, game states	In progress
3. Buildings & Objects — placement, houses, stations, scenery	Partially done
4. Track System — switches, pathfinding, junctions	Partially done
5. Trains — movement, carriages, speed control	Not started
6. Minifigures — spawning, walking AI, train boarding	Not started
7. Simulation Loop — tick rate, pause/speed controls	Not started
8. Polish — audio, particles, undo/redo, settings	Not started

Further out: multiplayer (LAN), postcard system, seasons/weather, train customization, and easter eggs from the original game.
