How to code a value to increase when moving the mouse

[HereforM]

I'm trying to have a value to increase when the mouse is moved over an image while the mouse button is held down, is it possible to code this in renpy? Additionally, how would i have a value increase or decrease over time. Thanks!

try:

Code: Select all

default my_variable = 0
screen text:
    button:
        text "test"
        action NullAction()
        hover SetVariable("my_variable", my_variable+1)

I didn't run the code so it might contain errors
