Custom easing: inOutBack

#1

Hey,

In my eyes the inOutBack-easing is a little too “expressive”. I’d like that the objects don’t strike out that much. Is this somehow achievable?

Thanks so much in advance,

Phil

unfortunately you can’t get at the “s” value used to determine the amount of overshoot.  corona’s implementation seems to follow the 10% overshoot amount you typically find.

you can however write your own easing function.  start by borrowing any one of the ten thousand implementations of Penner’s equations (nine thousand of which, give or take :D, will be easily discoverable on the web),  make sure it works as intended within Corona, where such functions need to be in the form ease(t,tmax,start,delta), then tweak “s” as desired.

fwiw, just blogged about it (with code) here

Wow, this is great!

Thank you so much for this post!!
