Duplicated text in NVL screen with a viewport.

#1 Post by Zeroized » Tue May 08, 2018 1:18 am

Greetings.
I added a viewport to the NVL screen and I'm using it to display text. The viewport works, I can show long paragraphs and I can scroll them, however, when I scroll I can see the original text behind the viewport, like I have the normal NVL screen displaying the text and over that screen the viewport. I tried to fix it, but nothing works.
Any ideas about how to fix this? I attached the code I use for the NVL screen.
Thanks in advance.

Code: Select all

screen nvl:
    $ number = 0
    on "show" action Show("quick")
    on "hide" action Hide("quick")

    window:
        style "nvl_window"
        
        has viewport:
            scrollbars "vertical"
            mousewheel "change"

        has vbox:
            style "nvl_vbox"

        # Display dialogue.
        for who, what, who_id, what_id, window_id in dialogue:
            window:
                id window_id

                has hbox:
                    spacing 10

                if who is not None:
                    text who id who_id

                text what id what_id

        # Display a menu, if given.
        if items:

            vbox:
                id "menu"
                
                for caption, action, chosen in items:
                    $ number +=1
                    if caption == "Back":
                        if action:
                            key '0' action action
                            button:
                                action action
                                style "nvl_menu_choice_button"
                                text caption style "nvl_menu_choice"
                        else:
                            text caption style "nvl_menu_caption"
                    else:    
                        if action:
                            if(number <= 9 and number != 0):
                                key str(number) action action
                            button:
                                action action
                                style "nvl_menu_choice_button"
                                text caption style "nvl_menu_choice"
                        else:
                            text caption style "nvl_menu_caption"

    add SideImage() xalign 0.0 yalign 1.0

Can you show us screenshot to clarify what you mean?

From what I understand, you've got two versions of the NVL screen being displayed, one with the viewport and one without - but since your window has transparency you can see through the viewport version to the one underneath and you can notice it when you scroll the text.

If that's the case the more likely issue is that two NVL screens are being shown, meaning the problem won't be in the screen code but somewhere else.

I'm only guessing based on my understanding of what you said though.

Not sure what's going on, but the python parts ($ number ~ ) probably don't work anyway. Where did you get this? How are you using it? (i.e., not the screen part, the script part)

Yeah it's a window over a window, you need to check how you show the nvl window to see what's triggered it to show two. I can see the scrollbar in the window beneath, so it's the same screen duplicated.

I don't think it's related to the nvl window.
I've been doing some tests, the screen duplicates only when a menu with two or more options appears.
If I display a menu with only one option, there are no duplicates on the screen. Maybe the vbox there is making weird stuff happen?

How weird, can you show us the code to the nvl dialogues?

May need someone more cleverer than me to figure this out, I can't see where the problem is in the screen code, so unless Renpy does something weird when it loads NVL screens with multiple menu options, but I don't see why it would o.O

        #    jump background_done
I only uncomment the 2nd option on the menu and the text gets duplicated.

I'm afraid I'm really not sure what it could be from that. Out of curiousity, have you used define menu = nvl_menu?

Can you also show us the code after the menu jumps? I can't tell from your description whether the the overlapping happens immediately or after the menu choice happens.

If, by some strange reason, it's because nvl_mode and viewport don't mix well, then it's a bug that you need to report. But maybe someone more experienced can figure out what's really going on.

All I can tell from the screenshot is that you've got two screens (both with viewports) on top of each other. I don't have the actual text as reference to see whether the screen underneath is identical to the one above - so I can't eliminate that possibly either. Perhaps you should start a new project, just copy over a bare minimum of the code you used to create the viewport screens, and try and recreate the problem - then share the entire code with us, then we can get hands on to have a look?

I apologize for the doubleposting.
I can't replicate the bug on a new project, but as a solution I created a new screen called "nvl_choice" to display the menu.
The problem is that the new menu is displayed as an ADV style menu, the whole text on the screen disappears and the menu gets displayed in the middle.
How can I display it as a NVL style menu? As in, displaying the choices under the screen text.

Can you not recreate it with your original game's code? How did you do it in your original game code?

I copied the screen code to a new created project, and it works without issues. The problem lies on the main game.
In fact, using the displayable inspector I can see that everything works properly until a menu with more than one option gets displayed. Then, a whole new NVL screen appears, showing the same text and the menu options.
Now, after digging on the documentation, I created a new menu screen called "nvl_choice", but now, when I display a menu, the NVL screen that should be displaying the text disappears.
I want to check if the text gets duplicated if I use the "nvl_choice" screen and if it does, I'll just use ADV menus and call it a day.
