Error trying to load save/load/preferences screen from custom menu

[Tarish]

Hi there.

I'm trying to make a custom game menu with imagebuttons, following that tutorial I found here:
viewtopic.php?f=51&t=22394#p283224

More or less, everything works correctly, but when I try to make the Save/Load/Preferences button go where they should, an error appears:
The code looks like that:

Code: Select all

$ _game_menu_screen = "game_menu"

screen game_menu():
    tag menu
    add "images/background.png" xalign 0 yalign 0
    zorder 102
    
    imagebutton:
        focus_mask True
        idle Transform("images/Preferences.png")
        hover Transform("images/Preferences Hover.png")
        action [ShowMenu("preferences")]
    
    imagebutton:
        focus_mask True
        idle Transform("images/Save.png")
        hover Transform("images/Save Hover.png")
        action [ShowMenu("save")]
    
    imagebutton:
        focus_mask True
        idle Transform("images/Load.png")
        hover Transform("images/Load Hover.png")
        action [ShowMenu("load")]
        

As I say, now pushing the right mouse button, the screen shows every image as it should, and the custom actions ("jump inventory", and that kind of things) work without problem, but when I click any of these three buttons, the next error pops:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Any advice about what can be the cause, and how can I solve it?

Thank you very much.

Edit: Things I've tried and still give error:

Code: Select all

screen game_menu:

(no brackets)

Code: Select all

action ShowMenu("preferences")
action [ShowMenu('preferences')]
action [Show("preferences")]
action [ShowMenu("preferences_screen")]
action [Jump("preferences")]
action [Scene("preferences")]
action [Screen("preferences")]

Yes, some of them, I've actually tried to improvise, seeing that nothing I found worked. Also, I've tried any combination of them (i.e. action Show('preferences'), for example)

I'm not sure but you have the actions inside a list.
Try removing the square brackets and see if it helps.

Code: Select all

action ShowMenu("load")

I've tried it already, but it didn't work, either. I'll edit the post with the things I've already tried.

Well, this is Sparta the GUI system, and you kind of broke it...
Check the original screens.rpy file.
Preferences screen uses game menu screen with some arguments, so game menu must have these arguments (they are placed in bracets)

Code: Select all

screen game_menu(title, scroll=None, yinitial=0.0):

In your code there are no arguments for game menu screen.
So, either add these arguments for the game menu screen or change/delete the line in preferences screen (and other screens)

Code: Select all

use game_menu(_("Preferences"), scroll="viewport"):

That's the actual story of my life

Thank you very much, I'll take a look at it, and see how I can fix everything. I was getting crazy trying to find the cause of the error, your answers have enlightened me.

Thank you!
