[solved] How to use transformations on pre-existing windows.

[texi]

I tried to set what as the window's name but that didn't work. This is using renpy.show(). The window in question is generated by a function. I want to make it move when an option is selected.

When you say windows, do you mean screens? If so, you can set the transform to a variable and change the transform attached to it, the use renpy.restart_interaction()

Simple example:

Code: Select all

init:
    transform number_one:
        xpos 0.5 ypos 0.5 
        linear 1.0 xpos 1.0 ypos 0.5
    transform number_two:
        xpos 1.0 ypos 0.5 
        linear 1.0 xpos 0.5 ypos 0.5

init python:
    changing_transform = "None"

screen example_screen:
    add "example image at changing_transform
label start:
    $ changing_transform = number_one
    show screen example_screen #brings up screen with transform number_one being executed
    $ changing_transform = number_two
    $ renpy.restart_interaction() #refreshes active screens, which will activate the now changed changing_transform and apply it

Please note that because renpy compiles init python's before standard init's you cannot assign a transform to a variable during initialization. You have to do it within the running code.

No, sorry, I meant a window as in the displayable text box. It's not just specific to windows as well, images too.

It isn't easy to understand what you're asking (it seems what you are calling "window" is, in fact, a screen). Anyway, to apply a transform to a menu screen, you just need to define the transform first, as Evildumdum explained. For example:

Code: Select all

    transform rising:
        subpixel True
        alpha 0.0 yoffset 500
        parallel:
            ease 0.6 alpha 1.0
        parallel:
            ease 0.6 yoffset 0
        yoffset 0 alpha 1.0

Then, for example, to show the preferences screen with that transform, you just edit the preferences screen in screens.rpy:

Code: Select all

screen preferences():

    tag menu

    if renpy.mobile:
        $ cols = 2
    else:
        $ cols = 4

    use game_menu(_("Preferences"), scroll="viewport"):

        vbox:
            at rising # here, I changed 'with dissolve' to 'at rising'

I think the question is how to apply transforms to the screen when a button on it is pressed. As in, the screen is already shown and is waiting for input.
