Can't Pickle error upon trying to save [solved]

#1 Post by needchocolatenow » Wed Sep 06, 2017 9:34 pm

Hi, I'm fairly new to coding and I've come across something that's been making me scratch my head. I'm not sure how to fix it or what I've done wrong. The game runs fine, but saving brings up this error. Perhaps someone can explain to me what I've done wrong?

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "renpy/common/00gamemenu.rpy", line 173, in script
    $ ui.interact()
  File "renpy/common/00gamemenu.rpy", line 173, in <module>
    $ ui.interact()
  File "renpy/common/00action_file.rpy", line 357, in __call__
    renpy.save(fn, extra_info=save_name)
PicklingError: Can't pickle <function pickNotebook at 0x1055c8488>: it's not the same object as store.pickNotebook

Yes, I have seen that thread; I haven't imported anything so I'm not sure if my solution would be the same as the OP of that thread. I used define config.use_cpickle = False to get the above tracelog. I tried define config.save_dump = True and I got the following code, which didn't tell me much. Maybe this tracelog is more useful for others?

Code: Select all

I'm sorry, but an uncaught exception occurred.

Code: Select all

IOError: [Errno 13] Permission denied: 'save_dump.txt'
That simply means Windows is refused to create and save a file name 'save_dump.txt' to the drive. I wonder if run Ren'Py again as administrator would help? It could be the same problem why you can't save in Ren'Py game also.

EDIT: Oh, Darwin-14.4... is that Linux dist or a Mac? It's all simply come down to OS refused to create a file because of permission problem still. Wondering how to bypass that on a Mac... sudo and Terminal?

EDIT2: You can try run the game on Windows and see if it still giving the same error when save. If it doesn't, that really point to Mac OS permission issue.

EDIT3: Does create a new project and try to save in there working?

I'm on a Mac and I should have permissions for saving. I created a new project and saved as you said to try, and the new project saved and loaded correctly.

[edit] Tried the game file I was working on in Windows; I get the error in the first post when I tried to save.

It wouldn't be OS permission then... next, I would try to replicate the error by add things in step by step to the new project until the error appears. Then I would know exactly what the last thing I did cause the error in the first place.

How do you define pickNotebook? You could get this error if it's defined in a python block rather than an init python block.

This is how I defined it in the script file.

Code: Select all

init python:
    def pickPencil():
        return pickPencil
    def pickNotebook():
        return pickNotebook

label start:
    default pickPencil = False
    default pickNotebook = False

Functions and variables share a namespace in Python. So when you have them sharing names like this, you're not going to get what you want.

Thank you, Tom! That's what did it. I'll be sure to keep my variables and functions separate from now on.
