Micropolis Unity Version

Micropolis is a ground up C# rewrite of the MicropolisCore system using the Unity engine to create a full blown Micropolis native game that runs on Windows, Mac, and Unix. It includes a fully working city simulation game true to the original along with several new features and improvements.



You’ll be able to install a copy of Micropolis once we have an installer (using Squirrel). In the meantime you can download or clone this repository and run it from within Unity (it’s not recommended to fork the repo at this time as there a lot of changes going on and the current codebase isn’t stable yet).


Please see our wiki for everything you wanted to know about Micropolis, but were afraid to ask.

Thursday, January 10, 2008 was the day Don Hopkins released Micropolis, an open source release of the original City Simulator, SimCity. I’ve been involved with Micropolis ever since the day Don told me about the release of the code. I immediately got into it, helped promote it, fixed up things in the code, and wrote a series of (unfinished) blog posts about it.

After all, this was based on the original SimCity source code right? How could I not do something with it.

The setup of the original code was hard. It required a ton of tools (SWIG, Tcl, Python, etc.) and resulted in a slow and klunky system that, when a crash occured, it was hard to tell if it was the graphics, the interpreter, the original code, or any one of the dozen or so subsystems in between.

Skip ahead a few years and, well, things haven’t gone too far. A few people have ran with the code but it never became the massive thing that the original SimCity ever was (and I didn’t think it would have). Instead there are a few ports of it to different platform (JavaScript, C#, etc.) but nothing to write home about.

So here we are with yet-another-port. I guess.

This Project

This rewrite of Micropolis represents a culmination of sources from the original Micropolis source code release which was made up of modified TCL/Tk C code (based on the original X11 Multiplayer Unix release of SimCity, but with the Multiplayer bits removed) and the C++/Python rewrite done by Don Hopkins.

Using both of these codebases as a reference, this project builds a C# 2D game using the Unity engine for graphics and UI. The result is a game that runs on modern hardware as a single stand-alone executable with the ability to port and run on other platforms (iOS, Android, etc.). No special tools are required to run it except a computer. The installation is a single click download (with built-in automatic updates so you always have the latest version).

Going beyond the origina, the plan is to continue to evolve this desktop version with new features that brings the old school gameplay of city building and new ideas together in a modern package.
