Re: [Flightgear-devel] How can I make a flight simulator like FGFS?

[Curtis O. <cur...@gm...>]

FlightGear provides all the source ... shouldn't be too hard to grab a copy
if you go to our main web site ... or do a quick google search.  We are
OpenSceneGraph based.

Glass half empty comment:  One downside to a code base that will turn 30
years old before too long is that it has continuously grown in complexity
over the years.  Diving into the source code from scratch (or if you
haven't poked around in there for a few years) can be quite intimidating.
I do think this is a downside to large, long-term successful projects like
FlightGear.  The code is open-source, but many areas are all but
impenetrable due to complexity and use of a lot of advanced C++ idioms ...
and we encapsulate a lot of advanced engineering concepts as well ... which
is unavoidable ... being a flight sim and all.  So depending on what you
are doing and where you are looking, there can be a huge learning curve to
deal with.  There are lots of people willing to address specific questions
that anyone might want to ask, but you have to be willing to put the enough
effort in on your side to get to the point of being able to ask specific
questions.  If your starting point is "how do you write a flight
simulator", then I don't think any of us have written texts books on how to
do that ... and when they exist, they are very narrowly focused ... like
you might need to learn visual basic or various severely dated technologies
to follow along with much of the information out there.  Anyway, I'm
starting to ramble into things I don't know as much about, so I should stop
here before I say too many things that are too terribly wrong. :-)
