[Bf-committers] BGE 2.49 external python modules...

[Campbell Barton]

Heres a video of how to use modules, though it looks like you got this far,
http://blenderartists.org/forum/showthread.php?t=156672

In 2.49 the blendfiles path is always added to the sys.path,

The module feature is not limited to...
 module.func
You can do this too...
  module.submodule.func
Or...
  package.module.func
Its not limited, if you wanted you could do this and it would not be
any slower to run...
  a.b.c.d.f.someFunc

The way the directories are setup for YoFrankie currently use python
packages, blender doesn't need to know about how packages work, python
does this automatic.

----- explained on the forum
@Sim88, Originally I made blender look in "./scripts" a bit like how
many games have "./textures"
where the blendfile was in...
/home/me/game/someGame.blend
/home/me/game/scripts/someScript.py
However this is a bit arbitrary.

A nicer way to manage this is with python packages
/home/me/game/someGame.blend
/home/me/game/MyScript/__init__.py
/home/me/game/MyScript/someScript.py

This way you can import the directory as if its a module, Look up py
docs on how to write a package, but basically __init__.py just needs
to import 'someScript.py'

Then the py-controller module can use the string
"MyScript.someScript.main"

Even though this seems a bit complicated Id assume youd only do this
in bigger projects where 10+ scripts are going to clutter your
directory.
In these cases setting up a python package is no bug deal, I tested
this for YoFrankie and it works well.
