_preferences.volumes['music'] generates "KeyError" [solved]

[korova]

OK, I'm doomed tonight.

Several codes that used to work perfectly now randomly generate errors.

I need to get the value of mixer volumes.
I use the variable _preferences.volumes['music'] and _preferences.volumes['sfx'], and later pass them to a screen.

This worked like a charm, and suddenly generates errors when I build distributions.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 97, in script
    define quick_boutons = [
  File "game/script.rpy", line 101, in <module>
    "action":Show("ecran_pause",music=_preferences.volumes['music'],son=_preferences.volumes['sfx']),
KeyError: 'music'

If I try to print the variable _preferences.volumes, it seems that it does have a "music" index.

I had the error once under linux, and now under windows (XP), no problem on Mac OS (I develop either on linux or Mac)

I don't understand the problem, can someone help me ?

You probably want _preferences.get_volume('music').

[korova]

Done.

Just for my knowledge, does this function touches the mixers or the channels ? (I always have trouble to make distinction between channels and mixers)

[PyTom]

The mixer.

Basically, there are a small number of mixers, which are shared by a large number of channels.

Thanks. Things are clearer now.
