Error that I just have no clue about.

Hi
I'm developing a small game with renpy
Recently some people have reported that they can't seem to be able to open they're old save games.

Code: Select all

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "renpy/common/00keymap.rpy", line 456, in 
  File "renpy/common/00keymap.rpy", line 466, in _execute_python_hide
AttributeError: 'renpy.display.matrix.Matrix2D' object has no attribute 'state'

-- Full Traceback ------------------------------------------------------------

Full traceback:

AttributeError: 'renpy.display.matrix.Matrix2D' object has no attribute 'state'

This is the error they've reported.
Can't seem to be able to replicate it on my own machine, and I honestly just have no clue.

Does anyone here know anything.
Thanks in advance.

This is just a guess, but have you changed versions of Ren'py since those saves were made?

This has the look of a situation where an instance of a class was saved (Matrix2D in this case) and when it's restored, something is different about the way the class is implemented in the version of Ren'py that's doing the restoring. The class that's being complained about is obviously one of PyTom's, so I'm wondering if the save was made with a different version of Ren'py that used a slightly different definition of Matrix2D.

If so, you might have to get someone to send you one of the offending saves and dump its contents to figure out what the offending saved variable is, and then see if you can hack your way around it.

Yes. I have changed versions.

Thanks.
