[SOLVED] How to show a Notify screen when player points at some words in a textbox?

#1 Post by Aureus »

Hello there! I already have some semi-complex mechanics related to hovering things and showing Notify screen with a variable-based text, but I would like to find out if there is an option to introduce something like this:
player sees dialogue textbox with some text, something like
"blah blah blah Random Words blah blah blah"
and if the player points their mouse at "Random Words" that belong to this text, the notify screen will appear with a customized text. Ideally, variable based.
My programming skills are quite limited, so do you know a way to do this without rewriting the entire engine?

You can (ab)use a tag for that:

Create a new project, then do the following:

First, change default style in screens.rpy:

Code: Select all

style default:
    properties gui.text_properties()
    language gui.language
    hyperlink_functions (lambda x: style.hyperlink_text, None, notifier)
(If anyone knows the names of default first two functions for hyperlink_functions, let me know)
It will disable ability to click on embedded links, so, if you need that, let me know, and I will think of the solution.

Then, replace script.rpy content with this:

Code: Select all

init python:
    def notifier(arg):
        data = arg.split(':')
        if data[0] == 'notify':
            renpy.show_screen('notify', data[1])
            renpy.restart_interaction()

label start:
    "You've created a new {a=notify:Ren'Py is a cool VN creation engine!}Ren'Py{/a} game."
    "Once you add a story, pictures, and music, you can release it to the world!"
    return
Test it.

Uh... I have a problem. : )

It still kind of works, but if I use notify for some other thing, and then try to use the solution from above, the game crashes.
I made a gif showing how does it look like.

Any ideas? : (

I'm sorry, but an uncaught exception occurred.

Change notifier function:

Code: Select all

# . . .
def notifier(arg):
    if arg is None:
        return
    data = arg.split(':')
    # . . .

Thank you, Ocelot, it's almost there! Currently, the part where the game was crashing out is replaced with highlighting and underlining the word and showing no Notify screen at all. The game doesn't crash and I can show the Notify message during the next attempt (even on the same word), but I was wondering if you have a solution how to make it more fluent. (In other words - how to avoid this "nothing happens" pause.)

Notify screen was not created to handle stuff like that. Maybe problem is in that, maybe something with how you display it for your name. It is hard to say exactly. Can you make an SSCCE?

I never heard about it, but I think I can do this - tomorrow or the day after tomorrow, my hands are currently completely full. Nevertheless, thank you very much for your help.

So... Here is the build with the bug description. The most important parts of the code:

Code: Select all

from Script:
define au = Character("Aure")
define aur = Character("Aureus") # to see that it works for more than one name
default npcs.speaker = None # npcs.speaker is taken from "say screen" with: "if who is not None: / on 'show' action SetField(npcs, 'speaker', who)"
default npcdescription = 0 # the button activating the Notify screen is activated only if npcdescription != 0

init python:
    def notifier(arg): #from the style default: "hyperlink_functions (lambda x: style.hyperlink_text, None, notifier)". it replaces the basic links 
        if arg is None:
            return
        data = arg.split(':')
        if data[0] == 'notify':
            renpy.show_screen('notify', data[1])
            renpy.restart_interaction() 

label start:
    show screen button_hover_example # the screen that shows hovering

$ npcdescription = 0
$ npcs.speaker = None
$ npcs = {"Aure" : "Hovering works fine!", "Aureus" : "Even with a different name!"} # we attach shown names to their descriptions

scene bg room
# first we have an empty message, so the game can start without crying that "npc.speaker" is unknown
au "Hi there! So here is my bug description, at first everything works fine:"
$ npcdescription = 1
au "1) Please point your mouse at my namebox. As you can see, it's showing the Notify screen whenever you hover it!"

au "2) Now, please point your mouse at {a=notify:Link also works fine!}this link{/a}. It does nothing when clicked, but it also shows a new Notify screen! Cool!"
# {a=notify:message}name{/a}
aur "3) Also, if you hover {a=notify:Link is still cool!}this link{/a} first and the namebox second, it all works as intended!"
# the bug starts here
au "4) However... if you first point on my namebox and then {a=notify:See the bug? : (}this link{/a}, at first it highlights the text and doesn't show Notify screen at all. You need to re-hover it to show the Notify screen." 
    
aur "I can live with that, but it is really annoying and will confuse my players. : ( Can you help me?"
$ npcdescription = 0    
au "Thank you so much for your time!"

return

Remove unhovered Hide('notify') function. Notify screen hides itself. I think, it happens because for some reason your button start taking whole screen and button unhovered even fired after link hovered event. Strange.
