Warning: changing the mouse cursor

[thelastsecret]

A warning for those of you who change the mouse cursor in-game:

I had in a previous version of Ren'Py changed the mouse cursor using something like
setattr(config, "mouse", {"1": [("images/1.png", 20, 20)]})
This somehow doesn't work anymore in version 7.5.1 of Ren'Py! There is no error message, but the cursor just doesn't change.
Instead one can use
define config.mouse['1'] = [("images/1.png", 20, 20)]
which works just fine.

... which is literally how you are supposed to do that, this method is described in the original documentation: https://www.renpy.org/doc/html/mouse.html

I do not know how you got to the first version, but it wasn't supposed to work for at least a few years. Any appearances of this to work are just coincidence.
