Actions on hovering - why won't my code work?

[lykoia]

Hey all, newbie here,

I wanted to change a variable on hover but unfortunately it doesn't work.
Here's the code:

Code: Select all

imagebutton:
        focus_mask True
        idle "1stfloor-button-idle"
        hover "1stfloor-button-hover"
        hovered SetVariable("schoolfloor", "0")
        xalign 1.0
        action NullAction()

Why won't it work?

Thanks in advance.

it because you have nothing in the action renpy is reading your code right by ignoring that button cause you have nullaction

hovered SetVariable("schoolfloor", "0") won't do anything not in less it has something in the action try putting setvariable in action

I changed it so it's now:

imagebutton:
focus_mask True
idle "1stfloor-button-idle"
hover "1stfloor-button-hover"
hovered SetVariable("schoolfloor", "0")
xalign 1.0
action SetVariable("schoolfloor", "0")

And it still doesn't work.
Did I do something wrong?

are you using define or default

Code: Select all

define schoolfloor = 0 (doesn't change)
default schoolfloor = 0 (changes)

action SetVariable("schoolfloor", 1)

define schoolfloor = 0 (doesn't change)
default schoolfloor = 0 (changes)

action SetVariable("schoolfloor", 1)

I'm using default

ok I did notice the you are putting "" around the number hovered SetVariable("schoolfloor", "0") when it should be hovered SetVariable("schoolfloor", 0)

I changed it but nothing changed.

Here's the entire code:

Code: Select all

screen mapweek00():
    default schoolfloor = 0
    imagebutton:
        if schoolfloor == 0:
            idle "school-map-00"
        elif schoolfloor == 1:
            idle "school-map-01"
        elif schoolfloor == 2:
            idle "school-map-02"
        xalign 0.5
        yalign 0.5
        action NullAction()
    imagebutton:
        idle "1stfloor-button-idle"
        hover "1stfloor-button-hover"
        hovered SetVariable("schoolfloor", 0)
        xalign 1.0
        action SetVariable("schoolfloor", 0)
       imagebutton:
        focus_mask True
        idle "2ndfloor-button-idle"
        hover "2ndfloor-button-hover"
        hovered SetVariable("schoolfloor", 1)
        xalign 1.0
        yalign 0.5
        action SetVariable("schoolfloor", 1)
    imagebutton:
        focus_mask True
        idle "3rdfloor-button-idle"
        hover "3rdfloor-button-hover"
        hovered SetVariable("schoolfloor", 2)
        xalign 1.0
        action SetVariable("schoolfloor", 2)

Maybe I did something wrong here?

Use SetLocalVariable or SetScreenVariable

Your actions/hovered (btw hovered will work with a NullAction on the action) are not altering the screen variable, just a global variable.
In most cases it makes more sense to just use global variables though (easier to keep track of)

Code: Select all

default var = 0 # GLOBAL

screen update_var():
    default svar = 10 # SCREEN
    vbox:
        text "Global: [var!q]"
        text "Screen: [svar!q]"
        textbutton "Add":
            hovered [
                # Increment GLOBAL variable
                SetVariable("var", var+1),
                # Decrement SCREEN variable
                SetScreenVariable("svar", svar-1) ]
            action NullAction()

label start:

    show screen update_var

    pause

It works! I've been looking for a solution for this problem for so long! Thank you so much!
