Hi

Viva is a small framework to define animation developed by igor Stasenko.
It is used by Roassal2 for its animation.
Now Viva is published in its own repository

and published in the configuration repository for Pharo 40.

Looks good, pretty much what I had in mind for a basic animation framework.

How about making the animated value more generic and independent of a timer, more

like a "binding"

source -> property binding -> target

and an (timer-)animated binding

timer as source -> property binding -> target

As I was thinking about an animation framework I got the idea of some more generic

components. The components I had in mind:
Clock

EventQueue

Task

Binding or PropertyWrapper

Range (as a source for interpolators)

Interpolators

Transition/Animation ( connection of a source(timer) and property bind, together with a range interpolator).

scaling/easing function (linear/quad/quadIn/quadOut)

Clock, EventQueue and Task classes (maybe we have some of them already)
may be usable for other things and are used here as building blocks for the (transition/animation) framework.

(The idea is, to not invent a TimerFrameWorkClock/ TimerFrameWorkEvent / TimerFrameWorkXXX....)

Do you know this Squeak (Morphic) Animation Framework

(https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki/animations) ?

I like how it wraps different property animation in different animation classes (AlphaBlendAnimation/ColorAnimation ...).

(I wonder why it is nowhere used)

And there is GLMAnimation, but I don't like how it is implemented.
