[SOLVED] Confused about interpolation using !i or !ti

[goldo]

Hi guys,

So I'm looking at this part of the documentation: https://www.renpy.org/doc/html/text.htm ... ating-data

But I cannot get this simple code to work:

Code: Select all

label test_interpolation():

        $ text1 = "Hello, [MC.name]."

        girl "[text1!ti]" # text1!i doesn't work either

        return

And then nothing happens (see attachment). Am I misunderstanding how interpolation works?

Of course I could replace the text with something like:

Code: Select all

"Hello, %s." % MC.name

or

Code: Select all

"Hello, " + MC.name + "."

But I would really like to make the first code work, it's just a lot easier to read and write, and the documentation makes it sound like it should work.

Any insight would be welcome. Thanks!

Hi, goldo,

I tried your code, it works fine for me. I guess MC is an instance of some class. Maybe the code of this class will help to understand why it doesn't work.

[goldo]

Well, MC is a complex class but its 'name' property has nothing special to it, it's just a regular variable that gets assigned a string upon starting the game.

Code: Select all

label start:
	MC_name = "Nero"
        MC = Main()    

init python:
    class Main(object):

        """This class is for the main character."""

        def __init__(self):

            self.name = MC_name
            
            [...]
            
            

The game runs on 7.3.5.606, so unless things changed recently, it should be working.

The only thing I can think of is that the game was created on an earlier version of Ren'py, back when '!i' didn't exist, and I ported it to 7.3.5 but maintained the old UI system (using themes).

The say screen thus looks like this:

Code: Select all

## Say screen ##################################################################
##
## The say screen is used to display dialogue to the player. It takes two
## parameters, who and what, which are the name of the speaking character and
## the text to be displayed, respectively. (The who parameter can be None if no
## name is given.)
##
## This screen must create a text displayable with id "what", as Ren'Py uses
## this to manage text display. It can also create displayables with id "who"
## and id "window" to apply style properties.
##
## https://www.renpy.org/doc/html/screen_special.html#say

screen say(who, what, side_image=False):
    style_prefix "say"

    # The one window variant.
    window yalign 1.0 ysize int(config.screen_height*0.2) xpadding 20 ypadding 10:
        id "window"

        has vbox:
            style "say_vbox"

        if who:
            text who id "who"

        text what id "what"

    # If there's a side image, display it above the text.

    if side_image:
        fixed xsize 150 ysize 150 xalign 0.0 yalign 1.0:
            add side_image xalign 0.5 yalign 0.0
    else:
        add SideImage() xalign 0.0 yalign 1.0

    # Use the quick menu.
    use quick_menu

style window is default

style window:
    xalign 0.5
    xfill True
    yalign gui.textbox_yalign
    ysize gui.textbox_height

    background Image("gui/textbox.png", xalign=0.5, yalign=1.0)

I don't think I really changed anything to it.

I believe !i is 7.4 and newer.

You should also default your variables. If MC_name does not change after you create it (doing it your way) there is no guarantee that Ren'Py will add it to the store (whereas with default there is a guarantee).
Creating variables in labels is not a good idea in modern Ren'Py. Either define them (not stored, just for values that never change) or default them.

Thank you, this is useful information.

Unfortunately I don't think this relates to my problem: MC.name is a string, and is used everywhere without problems. This works fine, for instance:

Code: Select all

girl "Hello, [MC.name]"

The game was originally created on Renpy 6.18.3 and updated with newer versions since.

Just to keep you guys updated; I couldn't get the double interpolation to work, but this works as intended:

Code: Select all

label test_interpolation():

        $ text1 = "Hello, [MC.name]."

        $ girl(text1)

        return

Good enough for my purposes. Thank you for your help!
