[SOLVED] Handling an error

[Galo223344]

My script changed, so now sometimes players will get the exception: "Couldn't find a place to stop rolling back. Perhaps the script changed in an incompatible way?" when loading a save file, I would like to handle this error by telling them that their save fils is incompatible and sending them to the main menu instead of showing an error screen and then hard-crashing. Is there any way for me to do this? I tried using after_load but the exception occurs before after_load takes place oddly enough.

Any help is appreciated!

Click the "force recompile" button on the RenPy Launcher screen, and see if it helps.

Oh, I don't want to fix the "Couldn't find a place to stop rolling back" (Unless it's posible) since the script did in fact change between versions. I just want to tell something else to the player besides a big exception screen.

Also, you can compare your saves' version to the current config.version or list of incompatible versions and identify yourself whether that save is compatible or not.

Code: Select all

define config.version = "2.0"
define incompatible_versions = ["1.0"]

screen file_slot(...):
    ...
    if FileJson(slot)["_version"] in incompatible_versions:
        text "Incompatible"

That's exactly what I was looking for, thank you very much!
