I'd object to the idea that development is easier in Python/whatever than
C++ - and once you take away that, why write slow code when for the same
effort or less, you can have fast code? I know a lot of Python/whatever
enthusiasts are going to object to that view - but for me personally, it's
I'd also object to the idea that games that get developed for Linux aren't
too complex...if we give into that idea then it will become a self-fulfilling
prophesy. Games I'm working on certainly *do* use all the resources of a
modern PC. I *want* to write the most complex game I can within the mental,
temporal and physical resources at my disposal.
Yes, you can write yet-another-Tetris without concerns for performance - but
you CAN'T write a game like TuxKart, FlightGear, etc in a scripting language
without the script being little more than a loop that calls compiled code
that does 99% of the work and probably contains 99% of the sourcecode.
The reason (IMHO) for using a scripting language for AI and things like
high level scenario management is that it makes the kind of parallelism
that I described earlier much simpler. This makes it much easier to think
about how the mental state of 50 computer-controlled characters might work.
It's hard to program with a state-machine approach - and running 50 parallel
pthreads isn't going to play well with a realtime game. If there was a
reasonable way to get extremely lightweight threading into
a compiled language - I probably wouldn't be interested in scripting.
There are (as far as I know) no large commercial games that are written
in a scripting languages. Many use scripting for AI and Scenario setup
There is a reason for that. Those guys aren't stupid.
