Instant CG and BG gallery

[leon]

To but a background behind, just list 2 displayables:

Code: Select all

g_cg.image("#000", gal_item)

To center/position the CG you can use im.Composite:

Code: Select all

g_cg.image(im.Composite((1280, 720), (0,0), "black.jpg", (200,200), ImageReference(gal_item)))

Thank you!

With the first solution, I have a background that appears.
Contrariwise, the second made ​​me the following error:

Code: Select all

I'm sorry, but an uncaught exception occurred.

While executing init code:
  File "game/gallery.rpy", line 7, in script
  File "game/gallery.rpy", line 41, in python
Exception: Expected an image, but got a general displayable.

Have you added an image called black.jpg to your game folder? Check the documentation for im.Composite or try it with LiveComposite if that doesn't work.

Code: Select all

g_cg.image(LiveComposite((1280, 720), (0,0), "#000", (200,200), gal_item))

Super ! It works perfectly !
Again thank you for your advice

[FrostGem]

Hi!

Thank you very much for the code it works really well .

This may be an odd request but is it possible to reset the gallery, like re-lock the images. You see I'd need to demonstrate that it works when I have to show this at college so I need to re-lock the image to show it unlocks at the right time.

Click on "delete persistent" in Ren'Py launcher.

Is there a way to make this work with automatically defined images, at all? I can't seem to get it to, it just throws up the Expected image, got general displayable error.

[leon]

It should work fine with automatically defined images. Try putting the part where you define the images in init -1.

[kirbysuperstar]

You mean the #Gallery Settings section? I only ask because as I'm having Renpy define everything for me, there is no image definition section.

[leon]

You could try using this code and add -1 to the init clause.

[kirbysuperstar]

Heeeey that worked beautifully, thanks a bunch!

Omg. At first, I tried to use this a couple of times and I couldn't figure out how to use it. But, I read the comments from others and found out! Yey! I was stuck with the image error thingy the whole time and couldn't figure it out until I found out that there was this tiny typo in the part where I define the images. GAH.

Thank you so much, though! It definitely helped me out a lot!

[chickenhearted]

I've been struggling with my lack of coding knowledge to get a CG gallery working, but this actually worked easily!

Celebratory dancing is in order~ :DD

Much thanks!

*sigh*

You've heard this problem many a time, yet it's just not fixing for me.

I'm unsure whether it's because I have to define images in the screens or in the 'script' but here we go.

Code: Select all

I'm sorry, but an uncaught exception occurred.

Help please...

As a quick fix you can just replace this:

Code: Select all

init +1 python:
    #Here we create the thumbnails. We create a grayscale thumbnail image for BGs, but we use a special "locked" image for CGs to prevent spoilers.
    for gal_item in gallery_cg_items:
        renpy.image (gal_item + " butt", im.Scale(ImageReference(gal_item), thumbnail_x, thumbnail_y))

with this:

Code: Select all

init +1 python:
    renpy.image ("apartment butt", im.Scale("apartment.jpg", thumbnail_x, thumbnail_y))
    renpy.image ("arcade butt", im.Scale("arcade.jpg", thumbnail_x, thumbnail_y))
