I will look into this on my end.






Hi Rumuald,
Is it possible there is a difference in the amount of change as effected by
the ease equation being used? I'm not sure which equations either package
uses.
In your hydroTween you are changing brightness from 0 to 2 to 0. In the
tweener its 0 to 1 to 0. That could make something appear to jump. I'd be
interested to see if there is a more technical reason or something as simple
as pulse rate.

Hi Guys,

 

I made a small test (file included). I've already posted it but nobody
answered, I renew my test with the last version of Tweener, Go and
Hydrotween.

 

I'm working on a project and it will use a tweener for the animations, I
won't get stuck with a package, the users will be able to register the
tweener they want to use, probably TweenLite, Tweener and Go+Hydrotween.

 

To be honest, after seeing the benchmarks and the features, I would like to
mainly use Go, but here's my problem.

 

I made a test to compare the reactivity of the different package. Using
Hydrotween and Tweener I animate a simple plane and a picture with rollover
and rollout, I change the properties brightness, scale and rotate.

 

Test it by opening the index.html, if you rollover the sprites, both will
work as expected, but if you rollover and rollout very quickly several times
to test the "reactivity of the engine", I can see that the Tweener one is a
lot smoother.

 

Here are the questions:

 

1 - Am I doing something wrong in my test?

2 - Can you see what I mean when I say Tweener is smoother?

3 - Is the problem coming from my test?

4 - Is the problem coming from Go?

5 - Is the problem coming from Hydrotween?

6 - Is the problem coming from the easing equation?

7 - is Hydrotween or Go parsing a big array or something that might make it
less smooth when the engine start again the tween?

8 - Can I (or we) solve it?

 

I don't want to shadow Go+Hydrotween at all, I'd like even to use it full
time but I've got to get a good result. Can you please tell me what you
think of that and if there's a solution or if you're going to have a look?

 

Thanks for your time.
