For now, while dev, I'm blocked on a save bug giving this log

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "game/script.rpy", line 34, in script call
    call showScreenMain
  File "game/script.rpy", line 49, in script
    python:

    renpy.save(fn, extra_info=save_name)
PicklingError: Can't pickle <type 'module'>: it's not found as __builtin__.module

PicklingError: Can't pickle <type 'module'>: it's not found as __builtin__.module

Windows-8-6.2.9200
Ren'Py 6.99.12.4.2187
BIOT 0.1.0
{size=10}(Lang 00 - Défaut){/size}
I suppose the inportant line is
pickle.dump(o, f, pickle.HIGHEST_PROTOCOL)
saying process can't dump an object but how is it possible to know with object is concerned and what is clearly the problem?

When it comes to this problem, there are two things you can do to make debugging it easier:

Code: Select all

define config.use_cpickle = False
define config.save_dump = True
The first will improve the error message, while the second will create a file named save_dump.txt with everything being saved in it. (If you see a module, that's your problem.)

This generally comes down to code like:

Code: Select all

python:
    import modulename
Imports should only ever happen inside an init python block, since Ren'Py can't save modules.

Thanks, you win :)

As said I tryed a lot of thing I did found on the web like define config.use_cpickle = False but did not know about your second tip, I'll try it.

I did find the problem by using old-school debugging (module by module, line by line, ...) and it was what you said, I used an 'import' in a screen (import time), provoking the crash.
