Hide/switch lists of items in journal on button click

#1 Post by wtxart » Wed Jul 11, 2018 3:43 pm

I'm trying to create a journal for a mystery game that records the main character's observations through the course of the story. Other games describe the same functionality as a codex or glossary.

My goal: a screen, accessible from navigation, which displays categories as textbuttons, such as People and Objects. When Objects is clicked, the screen displays a list of objects. When People is clicked, the objects list disappears and is replaced by a people list. The category buttons remain visible.

What I have: a screen, accessible from navigation, which displays categories. The buttons are set to Return as a placeholder.

My question: I don't know if I should be making the lists with multiple screens, vboxes inside a screen, etc., and since I'm not an experienced coder, there's a good chance I'm missing something obvious. How do I make lists that I can conditionally show and hide on button click?

Code: Select all

label journal_start:

screen journal():

    tag menu

    use game_menu(_("Journal"), scroll="viewport"):
        
        frame:
            vbox:
                style_prefix "radio"
                label _("Categories")
                textbutton _("People"):
                    action Return(True)
                textbutton _("Objects"):
                    action Return(True)

There are more questions in that than is easy to handle in one post, however, here is an example on one way you could show different lists by pushing a button. I'm trying to keep it very simple so it should be easier to understand.
When you get the principals you can use that to make something different looking.

Code for script

Code: Select all

image bg purpleBG= "#f0f"

default listC=0

label start:

    $ l1_list=["stuff 1", "stuff 2", "stuff 3"]
    $ l2_list=["other Stuff 1", "other Stuff 2","other Stuff 3","other Stuff 4"]
    $ l3_list=["item 1", "item 2"]

    jump notebook

label listcounter:
    $ listC += 1
    if listC>2:
        $ listC=0
    jump notebook

label notebook:
    show bg purpleBG
    show screen notes

    $ renpy.pause (hard=True)

label someThingElse:
    hide screen notes
    "the End"
    return
    
code for screen

Code: Select all

screen notes:
    textbutton "lists" action Jump ("listcounter") xpos 10  ypos 60
    textbutton "exit" action Jump ("someThingElse") xpos 10 ypos 80


    if listC==0:
        text l1_list[0]:
            xpos 80
            ypos 60
        text l1_list[1]:
            xpos 80
            ypos 80
        text l1_list[2]:
            xpos 80
            ypos 100

    elif listC==1:
        text l2_list[0]:
            xpos 80
            ypos 60
       text l2_list[1]:
            xpos 80
            ypos 80
        text l2_list[2]:
            xpos 80
            ypos 100
        text l2_list[3]:
            xpos 80
            ypos 120

    elif listC==2:
        text l3_list[0]:
            xpos 80
            ypos 60
        text l3_list[1]:
            xpos 80
            ypos 80
The way the lists are written out in the code above is not a very effective way. I did that to make it more clear what is happening. A better way to do it is this.

Code: Select all


     $ yp = 60

     if listC==0:
        for item in l1_list:
            text item:
                xpos 80
                ypos yp
            $ yp += 20

    elif listC==1:
        for item in l2_list:
            text item:
                xpos 80
                ypos yp
            $ yp += 20
            
    elif listC==2:
        for item in l3_list:
            text item:
                xpos 80
                ypos yp
            $ yp += 20

It does the same thing but will work even if the length of the list is changed by adding or removing items.

I hope this is of some help.

Thank you for responding. I tested your code, and it does work, but I believe I've miscommunicated what I was going for. I want to elaborate on the code I've already written, but I don't know how. Sorry for the confusion.
Just now, I tried showing a screen, which I thought might work because I know you can toggle a screen's visibility, but it crashed.

My code:

Code: Select all

label journal_start:

screen journal():

    tag menu

    use game_menu(_("Journal"), scroll="viewport"):
        
        frame:
            vbox:
                label _("Categories")
                textbutton _("People"):
                    action Show(j_people)
                textbutton _("Objects"):
                    action Return(True)

screen j_people():
    
    vbox:
        text "Test."
The error:

Code: Select all

I'm sorry, but an uncaught exception occurred.
