non-permanently changing side image alignment?

[PMscenarios]

I have been trying for hours now to get the side image for one of my two characters to align to the right instead of the left, and no matter what I do it seems to prefer the side image guideline already defined in screens.rpy

Neither defining the image with side image = Image("side_image.png", xalign=1.0), setting the alignment in the character itself, or writing it out works. (I also tried using the standard image and placing it on the dialogue bar, but besides that requiring me to change the text box and/or layers, it also seems to mean I need to hide the image manually every time it switches to the other character?)
I feel like I've tried every variation suggested in the different threads on side images I found when searching.

I don't want to change the "screens.rpy" statement, because I want the other side image to have the default left alignment.

Can I write an if/else statement for the screens.rpy say screen to toggle the alignment?

I remember having the same issues. What cleared it up was having a transform that changed the place of the image.

So my coding is this

Code: Select all

image side Sophia_side = Image("images/sophia.png", yalign=1.0, xalign=1.0)
define s = Character("Sophia", image="Sophia_side")

define config.side_image_change_transform = change_transform

transform change_transform(old, new):
    contains:
        old
        alpha 1.0
        linear 0.3 alpha 0.0
    contains:
        new
        alpha 0.0
        linear 0.3 alpha 1.0
