Custom Preference in Screen Language [Solved]

[Aleema]

Dumb question time.

The switch to SL seems like it would be perfect for adding whatever we want to game menus, since having a custom preference option wasn't possible with imagemap layouts before.

Thing is, I'm stupid, and I can't figure out how to add a custom preference option to the preferences screen that isn't hard coded in.

What actions should I implement for this to happen, so I could have an option to turn off mini-games, for example?
Is it possible? Because I'm looking at the guts of Ren'Py, and the "preferences constructor" looks pretty hard coded to not accept anything but what's there ...

I did that on PS to change layout and add the "difficulty" setting in the options, but it's no use posting the code here since is a total hack. I'd like to see (whenever pytom has time of course) some tutorials about doing this the "official way". Another option I wanted to use is "delete savegame" option in the load/save, but since I had fear of deleting users wrong files I gave up on this one

Aleema // Well, there's ToggleVariable or SetVariable action and I think you can simply add it to your preference screen.

Code: Select all

init:
    screen preference:
        #....
        has vbox
        text 'Do you want to do Mini-Games?'
        hbox:
            textbutton 'Yes' action SetVariable('minigame', True)
            textbutton 'No' action SetVariable('minigame', False)

#...
     
label minigame:
    if not minigame:
        return
    else:
    # ....

Anyway I didn't test it so I'm not sure it would work with your minigame code.

Oh, the variable has to be in quotes? I saw that action and tried it, got some string error, so I guess that was the original problem. Thanks, it worked.

Next problem: preferences should be persistent so you don't have to set them every time. I replaced a generic variable with this:

Code: Select all

textbutton _("Yes") action SetVariable('persistent.stopjukebox', True)

Got:

Code: Select all

AttributeError: 'module' object has no attribute 'persistent.stopjukebox'

Tell me I'm just being stupid again. >_<

[jack_norton]

That's the problem I had, I used a Class to set my variable (wasn't a persistent one though)

Ah... Try using SetFeild.

Code: Select all

init:
    $ persistent.stopjukebox = '1'
    screen test:
        hbox:
            textbutton "Yes" action SetField(persistent, 'stopjukebox', True)
            textbutton "No" action SetField(persistent, 'stopjukebox', False)
            textbutton "return" action Return()

label start:
    call screen test
    if persistent.stopjukebox:
        #...
    else:
        # ....

It worked!!
Thank you very much! You sure know your way around SL.

I know I'm necro'ing the heck out of this topic, but it's extremely useful for anyone wanting to add their own preferences. I'd volunteer to write a page about this in the Ren'py online documentation from this post if people wanted it.

I'd really appreciate it...
