[SOLVED] Exception: Not a displayable: None

[MisterHarold]

I tried making a gallery for my Visual Novel but I encounter an error whenever I use an imagebutton instead of just a thumbnail.

Code: Select all

screen gallery:
    tag menu

    add "pink2.png"
    
    $start = gallery_page * maxperpage
    $end = min(start + maxperpage - 1, len(gallery_items) - 1)

    #grid for images
    grid maxnumx maxnumy:
        xfill True
        yfill True

        for i in range(start, end + 1):
            $gallery_items[i].refresh_lock()
            if gallery_items[i].is_locked:
                add gallery_items[i].locked:
                    xalign 0.5
                    yalign 0.5
            else:
                imagebutton idle gallery_items[i].thumb:
                    action Show("gallery_closeup", gallery_items[i].images)
                    xalign 0.5
                    yalign 0.5

        for i in range(end - start + 1,  maxperpage):
            null

    #grid for info
    grid maxnumx maxnumy:
        xfill True
        yfill True

        for i in range(start, end + 1):
            hbox:
                spacing maxthumbx - 70
                xalign 0.5
                yalign 0.1
                $total = gallery_items[i].num_images()
                $partial = gallery_items[i].num_unlocked
                text gallery_items[i].name
                text "[partial]/[total]"

        for i in range(end - start + 1, maxperpage):
            null


    #previous/next buttons
    if gallery_page > 0:
        textbutton "Previous":
            action SetVariable("gallery_page", gallery_page - 1)
            xalign 0.1
            yalign 0.98
    if (gallery_page + 1) * maxperpage < len(gallery_items):
        textbutton "Next":
            action SetVariable("gallery_page", gallery_page + 1)
            xalign 0.9
            yalign 0.98

    #return button
    textbutton "Back to Main Menu":
        action Return()
        xalign 0.5
        yalign 0.98

screen gallery_closeup(images):

    add images[closeup_page] at truecenter

    if closeup_page > 0:
        textbutton "Previous":
            action SetVariable("closeup_page", closeup_page - 1)
            xalign 0.1
            yalign 0.98
            background "black.png"
    if closeup_page < len(images) - 1:
        textbutton "Next":
            action SetVariable("closeup_page", closeup_page + 1)
            xalign 0.9
            yalign 0.98
            background "black.png"

    textbutton "Return":
        action [SetVariable("closeup_page", 0), Hide("gallery_closeup", dissolve)]
        xalign 0.5
        yalign 0.98
        background "black.png"

The code I think that's responsible:

Code: Select all

                imagebutton idle gallery_items[i].thumb:
                    action Show("gallery_closeup", gallery_items[i].images)

The error:

Code: Select all

I'm sorry, but an uncaught exception occurred.

I want my gallery to show imagebuttons instead of thumbs so when I click it, it would show the full CG. Any kind of help would be greatly appreciated.

Code: Select all

                imagebutton idle gallery_items[i].thumb:
                    action Show("gallery_closeup", gallery_items[i].images)
                    xalign 0.5
                    yalign 0.5

Shouldn't that be

Code: Select all

                imagebutton:
                    idle gallery_items[i].thumb
                    action Show("gallery_closeup", gallery_items[i].images)
                    xalign 0.5
                    yalign 0.5

Where you append your images to gallery_items list,

Code: Select all

gallery_items.append(GalleryItem("Image 1", ["lostkei"], "thumb1"))
gallery_items.append(GalleryItem("Image 2", ["girlshadow"], "thumb2"))
gallery_items.append(GalleryItem("Image 3", ["gathering"], "thumb3"))
gallery_items.append(GalleryItem("Image 4", ["stars"], "thumb4"))
gallery_items.append(GalleryItem("Image 5", ["shake"], "thumb5"))

Shouldn't it be

Code: Select all

gallery_items.append(GalleryItem("Image 1", [ lostkei ], thumb1))
gallery_items.append(GalleryItem("Image 2", [ girlshadow ], thumb2))
gallery_items.append(GalleryItem("Image 3", [ gathering ], thumb3))
gallery_items.append(GalleryItem("Image 4", [ stars ], thumb4))
gallery_items.append(GalleryItem("Image 5", [ shake ], thumb5))
