Transform states in python

[Shlizer]

Hey,
I've got a problem with transforms and I was wandering if you can help with it. Currently I'm passing a transform function to change some states of my buttons, but I'd like to add some life to it, so I was wondering if there is possibility to add like in regular ATL block something like idle or hover states with easing animation? I mean, how can I do this:

Code: Select all

transform some_button():
    on idle:
        easein 0.9 xpos 0
    on hover:
        easein 0.5 xpos -60

Into this:

Code: Select all

transform some_button():
    function test_fn()

init python:
    def test_fn(tf,st,at):
         # how to modify tf object?
         return 0

I know I can calculate it manually, but I'm wondering if there is some out-of-the-box solution and how can I get current state of the element (eg. hovered or selected)? Source code says there's a arguments field in Transform class, that should have those states, but for me it's constantly empty.
