CG Gallery: span_buttons and unlocked_advance not working together

Hi guys,
I'm trying to make a CG gallery using the Gallery object:
https://www.renpy.org/doc/html/rooms.html
I want every picture displayed in the gallery as buttons, and the slideshow to advance between buttons. So I'm using:
span_buttons
If true, the gallery will advance between buttons.
I also want the slideshow to advance only through unlocked pictures. So I use:
unlocked_advance
If true, the gallery will only advance through unlocked images.
However, both attributes do not seem to play nice together. The slideshow advances between button as expected, but completely ignores unlocked_advance and shows every picture.
Do you guys know a way around this?

I think, but not quite sure, that depend on the Next() and Previous() actions "unlocked" properties you find in actual navigation screen in common/00gallery.rpy (i can't check it right now, give a try)

Both properties seem to be handled within the show method in
common/00gallery.rpy:
Code: Select all
def show(self, button=0, image=0):
"""
Starts showing gallery images.
`button`
The index of the button to start showing.
"""
# A list of (button, image) index pairs for all of the images we know
# about.
all_images = [ ]
# A list of (button, image) index pairs for all of the unlocked
# images.
unlocked_images = [ ]
for bi, b in enumerate(self.button_list):
all_unlocked = True
for ii, i in enumerate(b.images):
all_images.append((bi, ii))
unlocked = i.check_unlock(all_unlocked)
if unlocked:
unlocked_images.append((bi, ii))
else:
all_unlocked = False
if self.unlocked_advance and (button == bi) and (image == ii):
image += 1
self.slideshow = False
# Loop, displaying the images.
while True:
if button >= len(self.button_list):
break
b = self.button_list[button]
if image >= len(b.images):
break
i = b.images[image]
result = i.show((button, image) not in unlocked_images, image, len(b.images))
# Default action for click.
if result is True:
result = "next"
if result == 'return':
break
# At this point, result is either 'next', "next_unlocked", "previous", or "previous_unlocked"
# Go through the common advance code.
if self.unlocked_advance:
images = unlocked_images
else:
images = all_images
if (button, image) in images:
index = images.index((button, image))
else:
index = -1
if result.startswith('previous'):
index -= 1
else:
index += 1
if index < 0 or index >= len(images):
break
new_button, new_image = images[index]
if not self.span_buttons:
if new_button != button:
break
button = new_button
image = new_image
renpy.transition(self.transition)
I don't understand the code enough to tinker with it though, ideas would be welcome.
Also, how should I go about overriding this specific method for the Gallery object without having to redo all of
common/00gallery.rpy in my script?
