How can I make a out-game menu that can conditionally show texts and images?

#1 Post by apoto »

I was in the middle of making a crime visual novel, and I need to add a "evidence" menu to show all the evidences the POV has collected.
But when I tried to use the "if" sentence, it generated a traceback file and didn't work
Can somebody please help me?

Code: Select all

screen exhibit():
    tag menu
    use game_menu(_("Codex"), scroll="viewport"):

        style_prefix "codex"

        has vbox:
            spacing 20

        if  testflag2 = True:
             label "a"
             text _("a")

Code: Select all

I'm sorry, but an uncaught exception occurred.

After initialization, but before game start.

The problem is that you are using a single "=", this is used only to set someting, if you are checking for equalty then you should use double, i.e: "=="

Code: Select all

if  testflag2 == True:
However, if you are just checking for True/False, it's a bit simpler to just omit the equal part.

Code: Select all

screen exhibit():
    tag menu
    use game_menu(_("Codex"), scroll="viewport"):

        style_prefix "codex"

        has vbox:
            spacing 20

        if  testflag2:
             label "a"
             text _("a")

Thank you for your generous reply, however after trying this code, the game crashed after clicking the menu button.
related code:

Code: Select all

label start:

$ Testflag = False
$ Testflag2 = False

Code: Select all

screen evidence():
    tag menu
    use game_menu(_("evidence"), scroll="viewport"):

        style_prefix "evidence"

        has vbox:
            spacing 20
              label "a"
        if  Testflag2:
             label "a"
             text _("a")



define gui.evidence = ""


style evidence_label is gui_label
style evidence_label_text is gui_label_text
style evidence_text is gui_text

style evidence_label_text:
    size gui.label_text_size
the crash report

Code: Select all

I'm sorry, but an uncaught exception occurred.

Use

default Testflag2 = True

outside of any label or screen rather than $ Testflag2 = True inside a label
