Issue setting image directory with variable

[Spallidshorse]

Hello.

I've got a character status screen that shows stats and then an image of the character.

What I'm currently attempting to do is use a dict (posed) and variable (displayed_character) to generate sub-images by pointing renpy to a specific sub-directories within the image directory depending on the character or values in the dict. The sub-images are then passed to LiveComposite as layers of the final image. The sub-images are all the same dimension to avoid having to fiddle with a bunch of position values if we need to change one sort of sub-images (ie, if we need to change all the eyes).

Whenever image tries to find the directory variable, however, I get this error:

Exception: In DynamicImage u'[directory]/base.png': Could not find substitution 'directory'.

My guess is that this has something to do with how/when images are created, but I can't figure it out.

Any solutions? Is this just a no-go?

Code: Select all

init - 1 python:
	$define posed = {
	"position": "foo",
	"eyes": "bar"
	}
	
	$displayed_character = "baz"
	$position = posed["position"]
	$directory = "[position]/[displayed_character]"
	$eyes = posed["eyes"]

image base = "[directory]/base.png"
image eyes = Animation("[directory]/[eyes].png", 2.0, "[directory]/eyes shut.png", 0.2)

image status_screen_character_display = LiveComposite(
    (800, 600),
    (0,0), "base",
    (0,0), "eyes"
    )
    
   screen status():
   
   	add "status_screen_character_display"

lose the $ signs inside the python block... you only ever need them for simple one liners in Ren'py blocks...

Code: Select all

init -1 python:
    posed = {
	"position": "foo",
	"eyes": "bar"
	}
	
    displayed_character = "baz"
    position = posed["position"]
    directory = "[position]/[displayed_character]"
    eyes = posed["eyes"]

That does appear to define a lot of variable values outside of where you really need them though. It could well be easier passing them as parameters into a screen and having internal logic within the screen build the references

Untested code - maybe just add a few text "[directory]/[eyes].png" bits too to help debug

Code: Select all

screen show_char( position="foo", eyes="bar", char="baz" ):
    $ directory = "/".join( [ position, char ] )
    fixed:
        add LiveComposite(
            (800, 600),
            (0,0), "[directory]/base.png",
            (0,0), Animation("[directory]/[eyes].png", 2.0, "[directory]/eyes shut.png", 0.2) )

Whoops! I was fiddling with it right before posting and forgot I'd stuck the variables in a python block. Thanks/sorry!

This is closer to what I was thinking of doing. I'm just doing the most rudimentary step before I start messing with the screen and seeing what I can stick in functions/classes.

That said, removing the $ signs didn't fix the issue. I think the problem I'm running into is that Image() doesn't permit interpolating variables in the image location string, and implementing it as image bar = "[bar]" makes renpy think I'm trying to call DynamicImage which means "[bar]" is no longer read as pointing to a file but, I think, another image (if I'm understanding the purpose and function of DynamicImage).

I think I may just have to figure out ConditionSwitch

Can't you do a simple call, like this:

Code: Select all

    add LiveComposite(
            (800, 600),
            (0,0), ""+str(directory)+"/base.png",
            (0,0), Animation(""+str(directory)+"/"+str(eyes)+".png", 2.0, ""+str(directory)+"/eyes shut.png", 0.2) )

Not entirely sure you need the str() wrapper, I've just found that it sometimes helps when Renpy balks at whatever I try to concat.

concatenate the variables to fix it. quotes and + like this: ... see the variable? they're not within quotes.

Code: Select all

screen test3():
    for stuff1, stuff2 in thisobject:
       imagebutton:
         idle "1/2/" + stuff1 + "_" + stuff2 + "_idle.png"
         hover "1/2/" + stuff1 + "_" + stuff2 + "_hover.png"

(i know the post is old, but it came up in google, just wanted the solution to be there)
