SimCity Source Code Is Now Open

Tolkien writes "Source code for SimCity has been released under the GPLv3. For legal reasons the open source version was renamed Micropolis, which was apparently the original working title. The OLPC will also be getting a SimCity branded version that has been QA'ed by Electronic Arts. Some very cool changes have been made by Don Hopkins, who updated and ported what is now Micropolis. (Here is an earlier Slashdot discussion kicked off by a submission Don made.) Among other things, it has been revamped from the original C to using C++ with Python. Here is the page linking all the various source code versions. Happy hacking!"

Craptastic Code?

[DingerX]

FTA:

There's still a lot of craptastic code in there, but the heart of the software (the simulator) hasn't changed.

I dunno, from the QA side in 88/89, the results were darn clean. The simulation would crash from time to time, but the interface, never. To all those who point to multi-threaded apps and say it's too hard for coders to do, I'd suggest that really good programmers are hard to come by.

So maybe somebody can point to what's being complained about here. Back in the day, we didn't have the luxury of infinite space for code and variables. But from a quality-of-product point-of-view, very little could match (and can match) SimCity

The plane crash disaster has been removed as a result of 9/11 This is ridiculous. I hope fires have also been removed as a result of California fires, tornadoes as a result of the Indian ocean tsunami and the big monster invasion as a result of Cmdr Taco. Other wise it wouldn't be very respectful for the victims you know.

good news

That's amazing. It would be very nice if the code of other titles were released also. Many old (but good) softwares were forgoten because their sources were not available to maintain it's life.

Your post shows a deep lack of understanding of how and where Python is used, and for what purposes. As an example, Civilzation IV is written partially in Python (the user interface, as I recall), and EVE Online has a significant portion written in Python as well. Considering that a lot of what Python does is I/O bound, and a lot more can be done in outside libraries (e.g. DirectX), using Python in game development can make things a lot easier, and a lot easier to modify down the road.

Put aside your prejudices and you may actually learn something.

It's official, the terrorists have won.

The original SimCity code written in C ran just fine of an 8 bit 1.02 MHz 6510. And I've optimized to run even more efficiently since then. So worrying about Python slowing SimCity down is totally lacking in perspective -- penny wise but pound foolish. SimCity is already many orders of magnitude faster than it needs to be. Anyway, the core simulator is written in C, so Python doesn't slow it down at all. You should learn more about Python programming, developing Python modules in C and C++, and using SWIG for integrating Python and native code, and using Python as an embedded application extension language, before "making such [...] comments".

Using Python drastically speeds up the software development process, which is a great thing when software developer's time is so expensive, and computers are so fast. Python is also is a much easier language for kids to read, learn and program -- and the OLPC is an educational project, not a laptop project.

Re:Opportunity for a more realistic SimCity...

From Designing User Interfaces to Simulation Games, a summary of Will Wright's talk to Terry Winnograd's User Interface Class at Stanford, in 1996.:

Other people wanted to use SimCity for the less noble goal of teaching people what to think, instead of just teaching them to think.

Everyone notices the obvious built-in political bias, whatever that is. But everyone sees it from a different perspective, so nobody agrees what its real political agenda actually is. I don't think it's all that important, since SimCity's political agenda pales in comparison to the political agenda in the eye of the beholder.

Some muckety-muck architecture magazine was interviewing Will Wright about SimCity, and they asked him a question something like "which ontological urban paridigm most influenced your design of the simulator, the Exo-Hamiltonian Pattern Language Movement, or the Intra-Urban Deconstructionist Sub-Culture Hypothesis?" He replied, "I just kind of optimized for game play."
