With python 3.10, the games uses RenPy 8.0.0

It fails at script.rpyc, attached a zip with the file that fails.

script.zip

Here's my class_factory

class_factory = magic.FakeClassFactory(
    (
        frozenset,
        PyExpr,
        PyCode,
        RevertableList,
        RevertableDict,
        RevertableSet,
        Sentinel,
        set,
    ),
    magic.FakeStrict,
)

Update, changed renpy.python to renpy.revertable Now it fails at load_setitems

Having everything as renpy.python seems to get further before crashing (my added prints print 2000 lines vs 9000 lines)

Same error message with game using Python 3.9. Game: VIS 2.0 Script: script.rpyc (other as well but this one is little) file game available under https://dikgames.com/vis/ (season 2 so not too big)

script.rpyc.zip

Other game with 2.7 python base: Helping hotites (https://dikgames.com/helping-the-hotties hh.zip

Might test with solution on post: https://github.com/CensoredUsername/unrpyc/issues/156#issue-1416743346

Works with python 2.7

1. This should be in a way a duplicate of #146
2. In the opener post of user @Bexa2 the tool complains two times about File "G:\decompilers\rpa_decompiler\decompiler\magic.py", line 718, in safe_loads).load(). In line 718! The magic.py of the last version 1.1.8 has however only 674 lines.

Whatsoever version of unrpyc used was, makes every try of others to understand the code a waste of time.

Actually, #156 did fix my errors (on the games I tested), #146 was not enough.

As for the number of lines, black formatted on save, so my file has more lines.

Thanks for clearing this. It was confusing. Formaters can be a gift and hell at the same time. 😜

Did you use the whole of the changes form #156? @sigio uses in his pull request the change magic.py line 112 replace "if args or kwargs:" with "if (args or kwargs) and args != ([],) and kwargs != {}:" not, so i'am unsure if its needed. I noticed no problems only with the other corrections.

Yeah, I have a comment on that pull requests, those changes made it so it worked on one game and stopped working on another.

I think the change in magic.py is what made it work in both games.

Interesting. Ok, thanks. I will test this and see. 👋🏻

I just tried OnthePrairie-0.3.0-pc and it gave me the error

Just by changing

class RevertableDict(magic.FakeStrict, dict):
    __module__ = "renpy.revertable"

to

class RevertableDict(magic.FakeStrict, dict):
    __module__ = "renpy.python"

fixed it (Of course some other game will need the renpy.revertable in the future so I'll have to manually switch between the two), so it'd be nice to be able to use both, for new and old games.

Ahem... just a thought.. Which version has the game you used here? And if we're on it, which v. have the others you tested, where you changed back to renpy.python?

renpy.revertable should only be needed and actually working with Ren'py 7.5.x and 8.x. Just making sure nothing is accidentally overlooked.

btw.: The code change in magic.py is indeed also needed from the look of it. The pull request for the changes has it missing, but needs it to be complete.

This is also fixed. Problems arises not from Ren'Py v8 but from the revertable issue.

This is working on dev right now.

Should be fixed on master and releases as well now, so closing 🎉
