For my own education in Ren'Py, I'm coding a prototype that's supposed to advance one at a time through pages of images. (Currently, the images are represented by a placeholder called "squarey.png.") Like a gallery, but all the gallery tutorials I've seen use a list of different pages you can go to, rather than allowing the player to advance a page at a time.

The first screen below, callPageMain, appears as an icon during gameplay. You press the icon and it takes you to the "gallery" itself. This is working as intended.

The "gallery" consists of the screen pageMain for navigation ("Return," "Next" [next page], "Previous" [previous page]) and uses several screens (sheetOne, sheetTwo, sheetThree) in turn to display each page of images. Here's where the code doesn't work. The first page of images displays fine when the screen opens, but the button to advance doesn't work.

Also, mysteriously, the button to advance highlights properly when hovered-- but the button to dismiss the screen ("Return") does not highlight when hovered... though it still functions when pressed.

Code below. (Actual code contains proper indentations, which I don't know how to render on here.) If anyone can help me stop bashing my head against the wall, it'd be much appreciated.


image overlayBeige = Solid("F5F5DC")

screen callPageMain():
zorder 90

imagebutton:
hover "butty_hover.png"
idle "butty_idle.png"
xalign 1.0
yalign 0
action [Show("pageMain", transition=Dissolve(.2)), ToggleVariable("quick_menu", False)]

screen sheetOne():
tag menu
zorder 95
modal False
grid 2 2 at truecenter:
spacing 20
xspacing 100

image "squarey.png"
image "squarey.png"

image "squarey.png"
image "squarey.png"

screen sheetTwo():
tag menu
zorder 95
modal False
grid 2 2 at truecenter:
spacing 20

image "squarey.png"
image "squarey.png"

image "squarey.png"
image "squarey.png"

screen sheetThree():
tag menu
zorder 95
modal False
grid 2 2 at truecenter:
spacing 20

image "squarey.png"
image "squarey.png"

image "squarey.png"
text Null()

screen pageMain(passedPage="pageone"):
modal True
$currentPage = passedPage
zorder 100
add "overlayBeige"
sensitive True
if currentPage=="pageone":
use sheetOne
if currentPage=="pagetwo":
use sheetTwo
if currentPage=="pagethree":
use sheetThree
textbutton "Return":
align (.5,.9)
action [ToggleScreen("pageMain", transition=None), ToggleVariable("quick_menu", True)]
if currentPage=="pageone" or currentPage=="pagetwo":
textbutton "Next":
align (.75, .9)
if currentPage=="pageone":
action SetLocalVariable("currentPage","pagetwo")
if currentPage=="pagetwo":
action SetLocalVariable("currentPage","pagethree")
if currentPage=="pagetwo" or currentPage=="pagethree":
textbutton "Previous":
align (.25,.9)
if currentPage=="pagetwo":
action SetLocalVariable("currentPage","pageone")
if currentPage=="pagethree":
action SetLocalVariable("currentPage","pagetwo")

I could present the code indented and easier to read, but I still don't know how to get it to properly format on here and the FAQ doesn't tell me.

Thanks for the replies! I changed "$currentPage = passedPage," but I'm still having the exact same problem: the "Return" button works but doesn't highlight when hovered, whereas the "Next" button highlights but does nothing when clicked.

I'm not concerned over how to make a gallery. I just want to know why this code doesn't work which, to my eyes, should.

screen rotate():
    default numb=1

    if numb==1:
        text "one"
    elif numb==2:
        text "two"
    elif numb==3:
        text "three"

    if numb<3:
        textbutton "Next" ypos 30:
            action SetLocalVariable("numb", numb+1)
    if numb>1:
        textbutton "Previous" ypos 50:       
            action SetLocalVariable("numb", numb-1)
            
 

screen rotate():
    default numb2=1

    text str(numb2) 

     textbutton "numb2" ypos 30:
        if numb2==1:
            action SetLocalVariable("numb2", 2)
        if numb2==2:
            action SetLocalVariable("numb2", 3)
        if numb2==1:
            action SetLocalVariable("numb2", 4)
