Re: [pygame] setting + modifying a variable for use across the entire application

[Christopher Night <cosmologicon@xxxxxxxxx>]

Huh, that's really weird. I use this technique all the time, and I never worry about import order or having app-level values pre-set, and it always works perfectly as expected for me.

$ cat settings.py

sound_volume = 1000

$ cat module.py

import settings
def printvolume():

    print settings.sound_volume

$ cat main.py

import module, settings
module.printvolume()

settings.sound_volume = 3
module.printvolume()

$ python main.py 
1000

3

Not sure what you're doing different from me, but it might be worth looking into. There could be some other issue. Can you post a working example (like I did) where it behaves different than you expect?

I also don't understand why you're testing android == True in your code. That should never be the case. If the import is successful, android refers to some module, not the value True.

BTW guys, this is working for me. I'm using a module as an
application-level variable store. In my top-level main.py, I'm setting
variables that are referenced by modules down the line.

I had to do a couple things to make it work. One, the app-level
variables can't be already defined when imported, they have to be new
values which are set after the import by main.py. Two, any subsequent
modules which are imported have to import AFTER I'm done creating my
"app variables".

So it looks like this:

-----
main.py:

import acolyte_settings
try:
   import android
except ImportError:
   android = False
if android == True:
   acolyte_settings.ANDROID = True
   acolyte_settings.ASSETS_DIR = './assets'

import gameloop

def (main):
   gameloop.gameloop()

Now gameloop can use the acolyte_settings module to find out the
application settings. I don't have to write to an external file, or
constantly pass 'android=True' to all my classes. It's not all that
practical for multiple changes to the app-level variables, but for my
purposers, I like it!

Thanks for your help on this guys.
