[Solved] How do I add a custom value range on bar value Preference("font scale") ?

How do I add a custom range on bar value Preference("font scale")?

This is how the font size is normally changed from 00accessibility.rpy

Code: Select all

        bar value Preference("font size")
        textbutton _("Reset"):
             action Preference("font size", 1.0)

I'm trying to make a bar that changes the font size, but I want the bar value range to be between .8 and 1.1

Here is my code so far, but the function never fires. Maybe there is a better way to do it?

Code: Select all

```
screen test():
    #bar value FieldValue(_preferences, 'font size', .3, offset=.8): #doesn't work
    #bar value FieldValue(_preferences, 'font_size', .3, offset=.8): #doesn't work
    #bar value FieldValue(Preference, 'font size', .3, offset=.8): #doesn't work
    #bar value FieldValue(Preference, 'font_size', .3, offset=.8): #doesn't work
    bar value FieldValue(persistent, 'text_size_overall', .3, offset=.8):
       changed fts  

init python:
    
    # this function never fires when the slider is dragged.
    def fts(value):
        renpy.run(Preference('font size', value))
```

action
If not None, an action to call when the field has changed.

There's an action parameter to it.
