[Solved] Transform fails with SetVariable if the value is not changed

[_ticlock_]

Hi, All,

The_Sauce found the following strange behavior that seems to be a bug:

Action with SetVariable cancels transform effects if old and new values of a variable used in SetVariable are the same:

Code: Select all

default param = 0

transform expand:
    on hover:
        linear 0.12 zoom 2.0
    on idle:
        linear 0.05 zoom 1.0

screen test:
    imagebutton at expand:
        idle Solid('#f00', xysize = (200,200))
        hover Solid('#0f0', xysize = (200,200))
        action  SetVariable("param", 0)

label start:
    call screen test

Transform works if we change to SetVariable("param", 1), so the new value is actually different from the old one.

Firstly I thought that renpy interprets this as action None if value is not changed, but it also cancels transform effect if we add additional action that normally triggers transforms:

Code: Select all

    imagebutton at expand:
        action  [ Return(), SetVariable("param", 0) ] 

PS:

Either set selected (https://www.renpy.org/dev-doc/html/screens.html#button ) to False or add selected_hover, selected_idle to the transform. Also, by default, a button is selected if any action in the list of actions returns as selected, so adding more things doesn't change anything (for what you're trying to do).

I haven't realized it. Thanks a lot.
