[Solved] Game background scaling smaller background images(without cutting them off)

So maybe I'm just blind but I can't find anything on scaling the background images set through "scene bg ...". As I expected I didn't find any screens or styles linking to it. After not finding anything in scripts I tried the following
Code: Select all
image bg test = Image("bg/bg bg10.png", xfill=True)
scene bg test
image bg test = Image("bg/bg bg10.png", xsize=1066)
scene bg test
#cuts off parts
scene bg bg10:
zoom 2.0 (1.2-2.0 tested)
#causes error
scene bg bg10:
xfill True
#causes error
scene bg bgimg3:
xsize 1066
Is there some way to stretch the width? Preferably without having to write it out every command. Any help would be appreciated
My background images are 800 by 600 while the renpy window is 1066 by 600(smallest recommended size). For reasons I'd rather not get into, I don't don't want to post-process them. One platform that doesn't support renpy, I wrote a simple interpreter engine thing and I just scale the image up to I think it was 1.2 on the fly. (one of the reasons I don't want to change image sizes, is because it'll be on different platforms at different sizes).

You can have different amounts of resizing in the x and y direction using xzoom and yzoom.

I think you'd want 1.3325 scale factor to get from 800 to 1066
A consideration would be a displayable prefix, for example:
Code: Select all
init -10 python:
def scale_background(s):
return Transform(s, xzoom=1.3325)
config.displayable_prefix["scale"] = scale_background
# you could change scale to anything, like just 's' to use shorter 's:img' syntax
image bg one = "images/hex2.png"
# we *could* add the scale here during definition
image bg two = "scale:images/hex2.png"
label start:
scene bg two # already scaled during definition
scene expression "scale:bg one"
# using 'expression' and the scale: syntax inline
!! Realistically though, the best advice is just to set your game resolution to 800x600 !! (ignore anyone who says 1066x600 should be minimum)
