[Lyedka]

Hello!! sorry! SORRY for my bad english D:

wanted to know if you can create a button to delete persistent data the game in the screen configuration. (delete progress and saved)

Thank you!

From http://lemmasoft.renai.us/forums/viewto ... =8&t=23068:

This is unlikely to work from within the game, as the game will re-write the file as it quits.

Your best bet would be to just set the fields that you've set back to None.

So, write for all your persistent variables in this way:

Code: Select all

persistent.variable_name = None

As for deleting saved games...

Code: Select all

for slot in renpy.list_saved_games(fast=True):
    renpy.unlink_save(slot)
# Code tested!

For explanation, check out: http://renpy.org/doc/html/save_load_rol ... -variables

[nintendotoad]

Code: Select all

    $ persistent._clear(progress=True)

That actually (I believe) completely resets the persistent data. 'progress' is False by default; setting it to true resets Ren'Py's progress data. This is destructive, since the dictionary keys are completely destroyed.

If you'd prefer to leave the properties but still set them to None, you can do something like this:

Code: Select all

    def destroy_persistent():
        for attr in dir(persistent):
            if not callable(attr) and not attr.startswith("_"):
                setattr(persistent, attr, None)
        return

It should be somewhat simple to make a button use one of those functions.

Code: Select all

    textbutton _("Persistent Reset") action Function(destroy_persistent)

not working the Code to remove the saved, or I do not know how to make it work D:

        return

Code: Select all

    textbutton _("Persistent Reset") action Function(destroy_persistent)

when use "textbutton _("Persistent Reset") action Function(destroy_persistent)" this message appears:

I'm sorry, but an uncaught exception occurred.

I'm doing wrong? as I do?

(o^u^)o Thank you! o(^u^o)

You're using old version of Ren'Py, before Function action was introduced (you need to updated Ren'Py).

On a sidenote, "Function" is bloody useless here:

Code: Select all

textbutton _("Persistent Reset") action destroy_persistent

Is what you need assuming that function does whatever it is supposed to.

Thanks, I did no know that! But....

Ren'py doesn't want me!! ): D:

happened what I feared...

this is my code:

Well, you haven't defined 'destroy_persistent' in that code...

[Lyedka]

Little big mistake, as could be defined? I'm bad at this

[xavimat]

Well, nintendotoad gave you the definition:

Code: Select all

init python:
    def destroy_persistent():
        for attr in dir(persistent):
            if not callable(attr) and not attr.startswith("_"):
                setattr(persistent, attr, None)
        return

Put the definition outside the screen.
I don't know if this function works, but please read more carefully the answers people give you
