You can although it is still experimental (use of cel from pure python apps), because there are a couple more or less big problems (it was only possible by using the blpython till not long ago). Note i have a codebase to use twisted with crystalspace (or cel), so lemme know if you want to try that, and i can give you what i have.. This means you can do it, but there is no example because it is somehow still unsupported (the two problems being that you cant use celInitializer, and sometimes you get a second virtual clock out of nowhere -could be both problems are related, im investigating a little bit more these days-). Still, b2cs is using it "officialy", and i also have a celstart written in python which is a good example. > Secondly, if it can be done, realistically, how difficult will > development be?

What about examples? > Right now all cs and cel python docs that i know of are linked from: http://crystalspace3d.org/main/PyCrystal I recognize its not an incredible amount of examples or docs. There are also some other sources of example code, like ecksdee or interstate outlaws, b2cs, pycsel, the shader editor in csextra, apricot, cspop, and soon more and better :-) > I guess the final question would be this: has anyone seriously tried > active development on a python CS application? I been working with cs, cel and python since quite some time. Started a few apps, and seen a few more. My "advice" would be that the python bindings are really powerful, and pretty stable, but, the cs and cel is very big, so sometimes you will hit either a class that is not wrapped, or a method that doesnt work as expected from python, but normally i can make anything work, and for most stuff you can even do yourself.
