So sounds like you've done everything correctly. I assume you've kept the relative locations in the sys.path such as 'python', 'mods/bd2/python' and 'admin' as these are battlefield specific libraries it will try to load? Failing that, try the 32 bit version - maybe BF2 always runs a 32bit Python regardless of which version the game is running.

I 1. Replace the Battlefield 2 Python library (e.g. ‘bf2/bin/ia-32/libdice_py.so’) with the version of your choice. I just linked to my locally installed version ‘/usr/lib/libpython2.5.so’.
2. Replace the Python library path at runtime to use the new libraries, e.g. edit ‘bf2/python/bf2/__init__.py’ and putting the equivalent of ’sys.path = ['/usr/lib/python2.5/', '/usr/lib/python2.5/lib-dynload/', 'python', 'mods/bf2/python', 'admin']‘ after the ‘import sys’ line.

Is what I did, but I did substitute my version for 2.5. I used locate to find the directories for python. I run the 64 bit version of bf2.exe so I figured 64bit libs would be a proper replacement.

What exactly have you changed? Have you replaced (or linked) the libdice_py.so in the Battlefield directory with your own and editing the __init__.py? If that's all done, there might be an issue with replacing a 32-bit Python with a 64-bit one (which is what your directory names suggest) so that could be the cause.

I tried your method and when the server starts it crashes with "Import Error:" and flashes back to shell. I am using python2.4 and have changed the usr/lib/python2.5 to usr/lib64/python2.4 any clues?

Yes. Thank you.

Originally I wanted to use post methods, but I now think a simple get is more efficent for my level of coding. It also means that I can use the standard python lib that comes with bf2.

I appreciate the help.

Something like this should do the job:

import urllib
webPageHandle = urllib.urlopen('http://blog.garethj.com/')
webPageContents = webpage.read()

Then obviously you'll have to parse webPageContents for the information you need and use the BF2 API to send that into the game. This page looks like a good tutorial if you need more help: http://www.voidspace.org.uk/python/articles/url...

Hope that's useful :)

Yep. Requests for webpages in the existing python return garbage results so far. I'd like to be able to have a python script call a webpage, parse the results, then display the results in game.

I have the alternative version of Python running correctly doing what I need but I'm not sure what you mean by URL calls - is this the kind of thing you're after: http://www.python.org/doc/lib/module-httplib.html?

Well that is great news. Have you been able to get url calls working properly? I don't know much about python, but recoding our in game management system has been a fun experience. Right now, I'd like to use a url call to allow admins to register their keyhash via a php page and get a success or fail notification in game.

Hey Cal. Yes this works fine for me - let me know if I can help at all.

So is this running in a stable manner for you? I have some url calls I would like to make in the game and this would be a welcome help.

Hmm. I'm not really into games, but I'd still fancy a job where they crop as "work"!
