One SimCity Per Child

SimHacker writes "Electronic Arts has donated the original 'classic' version of Will Wright's popular SimCity game to the One Laptop Per Child project. SimCity is the epitome of constructionist educational games, and has been widely used by educators to unlock and speed-up the transformational skills associated with creative thinking. It's also been used in the Future City Competition by seventh- and eighth-grade students to foster engineering skills and inspire students to explore futuristic concepts and careers in engineering. OLPC SimCity is based on the X11 TCL/Tk version of SimCity for Unix developed and adapted to the OLPC by Don Hopkins, and the GPL open source code will soon be released under the name "Micropolis", which was SimCity's original working title. SJ Klein, director of content for the OLPC, called on game developers to create 'frameworks and scripting environments — tools with which children themselves could create their own content.' The long term agenda of the OLPC SimCity project is to convert SimCity into a scriptable Python module, integrate it with the OLPC's Sugar user interface and Cairo rendering library. Eventually they hope to apply Seymour Papert's and Alan Kay's ideas about constructionist education and teaching kids to program."

    That version of SimCity is the original SimCity Classic code written in C, packaged as an ActiveX control. It's not written in Java or JavaScript (or PHP for that matter).

    The version of the code we're releasing initially uses the TCL/Tk scripting language and user interface toolkit. But the simulation code itself is written in C. It's plugged into the scripting language, which can call it, but only integrated to a limited extent (just what the user interface required, not exposing all the workings of the simulator).

    Next we will repackage the original simulator as a Python module. The first step is to recast the original C code into a C++ class, so all the global variables and global arrays are local instance variables of a SimCity object, so you can have any number of simulations active at one time and they will not interfere with each other.

    After SimCity is recast as a C++ object, we will plug it into Python and other scripting languages by using SWIG, which is a nice way to integrate C and C++ code into a whole bunch of different scripting languages.

    Then we'll rewrite the user interface in Python, based on the other efficient modules that are integrated into Python but written in C or C++, including the GTK user interface toolkit for X11, the Cairo graphics library (like PostScript graphics but much better and hardware accelerated), the Pango text layout engine (draws with Cairo, supports internationalized text, so SimCity can support Unicode text and be translated into languages with non-English-like layout such as Chinese, Hebrew, Arabic, etc.), a C++ tile engine I wrote for Python that draws with Cairo, pie menus I wrote in Python that draw with Cairo, and many other useful modules.

    The idea is to open up the simulator so it can be easily and deeply scripted in Python. It was designed for the C64, so it can run extremely fast (on the order of a year a second) on the OLPC, and there is plenty of left over CPU power to call back into an interpreted scripting language like Python, and still be quite playable. It will still run very fast, because the core number crunching will still be written in C, but it will be able to call out to Python hooks and plug-ins, and Python will be able to reach in, tweak the simulation, change the parameters, edit the model, etc, so you'll be able to program your own disasters, monsters, tornados, editing tools, zones, artificial intelligence, robots, agents, etc. And also implement network sharing features, muti-player features, journaling and storytelling features, tivo-like fast forward and rewind features, etc. The goal is to inspire kids to learn Python programming and develop their own games, by reimplementing SimCity's user interface in terms of reusable components.

So we can make improvements to the TCL/Tk version of Micropolis (based on the GPL source code), and submit them to EA for review and QA, which if they approve, will be used as the officially branded version of SimCity for the OLPC. It will be the same code, but the only difference is the name, which EA understandably wants to protect, be ensuring the quality and integrity of OLPC SimCity.

    That said, I strongly encourage you to improve the TCL/Tk version of Micropolis, please! I think it would be great to keep the TCL/Tk development line of the code alive and strong, and modernize and improve it! It will be a fair amount of work to upgrade it, but that will be a lot less work and time than recasting SimCity in Python will require. Of course both projects can go on in parallel, learning from each other. Since the Python version won't be ready for a long time, we can submit an upgraded version of TCL/Tk Micropolis as the official version of OLPC SimCity, based on the latest TCL/Tk, including further OLPC/Sugar integration \(like making sound work better, supporting the gamepad, etc).

    TCL/Tk is a very cleanly written language and well designed user interface toolkit, which has grown and improved a lot since I took a snapshot of the code from around 1993 to use for SimCity. I have found memories of meeting Professor Ousterhout in his office on the UC Berkeley campus, and showing him the TCL/Tk version of SimCity, and thanking him for the great work he'd done and shared for free.

    The reason I want to convert the TCL/Tk version of SimCity to Python is because it's the "official" programming language for OLPC Sugar applications. In the short term, the OLPC will include applications like SimCity that uses TCL/Tk, eToys that uses Smalltalk/Squeak, etc. But in the long term, new software developed for the OLPC should be written in Python, to save memory by sharing modules, and to use great modules like Cairo for scalable stencil/paint graphics, Pango for rendering internationalized text, and all the Sugar modules written in Python.

    Despite not being written in Python, eToys and SimCity are included with the OLPC. The point is to educate and inspire people to develop new and better software, to bootstrap the software of the future. I'm compelled to move forward and develop a new visual programming language, better and easier to use than Python or TCL, that kids can use to reprogram the behavior and create extensions to SimCity, and even write their own games and who knows what else.

    Alan Kay wrote this on the OLPC Sugar mailing list, about implementing visual programming languages like eToys in Python:

    Guido knows that I've been advocating that the Python folks should do Etoys or a very Etoys like environment in Python (and that the rest of the OLPC be given an objectification and media and scripting integration that is Etoys like).

    However, there are simply zillions of things left to be done everywhere for OLPC so the first round of SW on the XO will be more of a gathering of "suggestive" features and abilities (of which Etoys is just one). That seems fine to me.

    Viewpoints Research (our little non-profit) doesn't have any "ego or identity" staked around whether the children's authoring environment is Python based or Squeak based. I have said many times that, if the general integrative base of XO is to be Python, then the Etoys-like authoring should be based in Python also.

    However, I will personally fight to the death to make sure that there is a children's authoring environment that allows even young children to do simulation style programming with very ri
