Micropolis is the Open Source Release of the original SimCity source code. This is a Java rewrite fork based on MicropolisJ by Jason Long, which was first released in Feburary 2013. MicropolisJ was functionality-wise almost equivalent to the TCL/Tk edition
The original game, SimCity, was developed by Will Wright. Don Hopkins released a GPL open source version named Micropolis as a part of the One Laptop Per Child (OLPC) program.
The forked version is Copyright (C) 2013 Jason Long ([email protected]). Portions Copyright (C) 1989-2007 Electronic Arts Inc.
To install and run this game, you need to install the Java Runtime Environment. You can get Java from https://www.java.com/
For development, please install the Java Development Toolkit. I recommend OpenJDK. You'll find an installation instruction here: https://openjdk.java.net/install/
The release archive comes with start scripts that ease the process of running the game.

The micropolisj.engine package contains the guts of the city simulation. It has no dependencies
on the front-end or any particular graphical system.
The micropolisj.gui package provides the user interface for the game. It renders the city, controls
the speed of the simulation, and responds to event messages from the engine.
A Gradle wrapper is included, so please just run
./gradlew build
to build the software and run the tests.
Unless you are an English speaker, you may like to run Micropolis in your own language. Micropolis is designed to be run in any language, but needs translators to provide the translated text to display.
If you want to translate the game to another language, please first determine the ISO 639-1 language
code of your target language, e.g. for Spanish use es (lower case). A list of language codes can
be found here: https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes
-
Fork the repository on GitHub and clone it locally.
-
Create a copy of each property file in
src/main/resources/stringsand rename the copy according to your language code. This little bash code will help you:
export language_code=es # change this according to your language
find src/main/resources/strings -regex '.*/\([A-Za-z]*\)\.properties' -exec sh -c 'filename={}; cp $filename ${filename%.properties}_$language_code.properties' \;-
Translate the lines within the new resources bundles.
