Creating a Slider for Text Size in Preferences

[lsf22]

Renpy version 8.1.3

I've been trying to get a working slider option for text size. So far it's set for dialogue of the game but I'm having trouble making it work. The current state of it is that it does not select any other size nor does the slider appear correctly.

Screens.rpy:

Code: Select all

	hbox:
	    style_prefix "slider"
	    box_wrap True
	    vbox:
	    	label _("Text Size")
		bar value gui.preference("size")
		#bar value Preference("size")
		null height (4 * gui.pref_spacing)

GUI.rpy:

Code: Select all

## The size of normal dialogue text.
define gui.text_size = gui.preference("size", 50)
#define gui.text_size = 44

I don't know why you think your preference called "text size" or "size" does anything at all. Where did you read that? Here is the official documentation for preferences: https://www.renpy.org/doc/html/screen_a ... Preference

So to change font size, you have to use:

Code: Select all

bar value Preference("font size")

The above is actually for scaling all fonts. If you want to change default sizes for certain gui elements, use gui.SetPreference and give the user some prebaked sizes to choose from instead. You cannot use this with bars, but buttons and fixed values. Now of course the user could use a bar to change a variable and then you use that variable to set the preference after he clicks or with a timer.
