Custom Viewport Screen Transition With Use

[orian34]

I've been using a custom screen menu to handle extras in the game, but I figured there was no transitions so I tried adding dissolve, but I can't make it work anywhere.
After looking more, I could use action ShowMenu() but I can't use actions in a viewport and use doesn't take parameters for transitions.

I feel like I lost brain cells because I can't figure out how to make it work.

glossary, gallery, glossary_desc, and library are 4 simple screens with a vbox and textbuttons.

Code: Select all

screen extras():
    tag menu

    use game_menu(_("Extras")):
        vbox:
            spacing 25
            hbox:
                style_prefix "radio"
                spacing 45
                xpos .2
                textbutton _("Glossary") action SetVariable('extras_mode', 0)
                textbutton _("Gallery") action SetVariable('extras_mode', 1)
                textbutton _("Library") action SetVariable('extras_mode', 2)
            viewport:
                scrollbars "vertical"
                vscrollbar_unscrollable "hide"
                mousewheel True
                draggable True
                xmaximum 1.0
                xpos .2

                if extras_mode == 0:
                    xpos .0
                    use glossary
                elif extras_mode == 1:
                    xpos .3
                    ypos .3
                    use gallery
                elif extras_mode == 2:
                    use library
        if extras_mode == 0:
            viewport:
                scrollbars "vertical"
                vscrollbar_unscrollable "hide"
                mousewheel True
                draggable True
                xmaximum 1.0
                ymaximum .85
                xpos .2
                ypos .15
                use glossary_desc

I managed to make it work, albeit with a fairly cursed solution, but it works.
I'm just making the action for the textbuttons refresh the menu through ShowMenu so it forces the transition.
Yay.

Code: Select all

		textbutton _("Glossary"):
                    action [SetVariable('extras_mode', 0),ShowMenu("extras")]
                    if not extras_mode == 0:
                        selected False
                textbutton _("Gallery"):
                    action [SetVariable('extras_mode', 1),ShowMenu("extras")]
                    if not extras_mode == 1:
                        selected False
                textbutton _("Library"):
                    action [SetVariable('extras_mode', 2),ShowMenu("extras")]
                    if not extras_mode == 2:
                        selected False

If you don't need the variable "extras_mode" outside of the screen, you could just make it an argument instead.

Code: Select all

screen extras(mode):
    ...
    textbutton _("Glossary") action ShowMenu('extras', mode=0)
    ...
    if mode == 0:
       ...

Thanks! Didn't know arguments were a thing.

After trying, I don't think it works for what I need anyway. It being an external variable means it saves even if you change menus and come back, so it's nice qol to have. Also I can't remove the if not condition because showmenu even with an argument will count all the buttons as selected since extras menu is already displayed.
