use of call with parameters [Sloved]

#1 Post by pyPat »

Hello, I have many thumbnail display, via screen, to do during a game. So I had the idea to group the necessary commands in a label called by call. After multiple tests i arrived at this code

Code: Select all

define j = Character("Jhon", color="#c8ffc8")

label play_screen(imageName):
    j "[imageName]"
    pause 1
    screen thumbnail:
        add imageName xalign 0.5 yalign -0.1
        modal False
    show screen thumbnail with dissolve
    return

label start:
    j "Hello!"
    call play_screen(imageName="thumbnail 01.png")

    j "first thumbnail "

    hide screen thumbnail with dissolve
    call play_screen(imageName="thumbnail 02.png")
    
    j "End"
    return
I have the following error message:

Thanks for your help
Maybe try to call the screen without its keyword(s). It's not some sort of kwargs based on how you defined it.

Code: Select all

call play_screen("thumbnail 02.png")

Re: use of call with parameters

Eureka !!! with this code is ok
if i understand correctly ren py does not have variable it is necessary to declare a variable via python and after using it in ren py is that it?
but why in this way j "[imageName]" displays the name of the image well ???

Code: Select all

define j = Character("Jhon", color="#c8ffc8")

label play_screen(imageName):
    j "[imageName]"
    pause 1
    $ nameThumbnail = imageName
    screen thumbnail:
        # add imageName xalign 0.5 yalign -0.1  : don't work
        add nameThumbnail xalign 0.5 yalign -0.1
        modal False
    show screen thumbnail with dissolve
    return

label start:
    j "Hello!"
    call play_screen("thumbnail 01.png")

    j "first thumbnail "

    hide screen thumbnail with dissolve
    call play_screen("thumbnail 02.png")

    j "End"

Re: use of call with parameters

you should pass the variable to the screen to use it in the screen. the variables passed as arguments are local to the labels or screens and can't be used outside of them unless they are passed around.

Code: Select all

define j = Character("Jhon", color="#c8ffc8")

screen thumbnail(imageName):
    add imageName xalign 0.5 yalign .5
    modal False

label play_screen(imageName):
    j "[imageName]"
    pause 1
    show screen thumbnail(imageName) with dissolve
    return

label start:
    j "Hello!"
    call play_screen(imageName="thumbnail 01.png")

    j "first thumbnail "

    hide screen thumbnail with dissolve
    call play_screen(imageName="thumbnail 02.png")
    
    j "End"
    return

Ok, I understand now
or I declare a python variable will be global
or I pass the local variable of a block to another.

Of course I should have thought. Thank you
