Lovely library.
Although I wanted to let you know, I was thoroughly confused for a couple of hours trying to figure out that using a special property like “_bezier” required:

import caurina.transitions.properties.CurveModifiers;
CurveModifiers.init();

Especially since the “bezierMaker_as3.fla” demo doesn’t make mention of it when printing source.

It makes perfect sense *now*, but it took me awhile to track down a definitive answer to this error message:

## [Tweener] Error: The property ‘_bezier’ doesn’t seem to be a normal object property of [object Test_mc] or a registered special property.

A small detail for such a wonderful package!
Thanks again for all your work.

The additional parameters are defined by the “transitionParams” property. ease*back has an “overshoot” parameter. Here’s an example:

http://hosted.zeh.com.br/tweener/docs/en-us/parameters/transitionParams.html

They follow Robert Penner’s original values. So for overshoot “higher values means greater overshoot (0 produces cubic easing with no overshoot, and the default value of 1.70158 produces an overshoot of 10 percent).”

ease*elastic is used in a similar way, but the parameters are “period” and “amplitude”. I never fully understood the role of each of them though, so it takes a while to get them working in the way you want. Default “period” is 30% of d (d being the difference between the start value and end value), default “amplitude” is 0.

No other transitions take parameters.

Great Work!!l.you inspired me.
Recently i’ve post on my blog a similar aproximation to this problem and i think i’ve found an alternative solution to this problem:

thanks for your idea. I tried to do so:
————————————————————–
import caurina.transitions.Tweener
caurina.transitions.properties.CurveModifiers.init()

var Path:Array = new Array()
// START AT
Path.push({_x:myMc._x, _y:myMc._y})
Path.push({_x:250, _y:150})
Path.push({_x:350, _y:400})
// END AT
Path.push({_x:550, _y:0})

myMc.oldX = Path[0]._x
myMc.oldY = Path[0]._y

function orientToPath(){
var rot = Math.atan2( (this.oldY – this._y), (this.oldX – this._x) ) * ( 180 / Math.PI )
this._rotation = rot
this.oldX = this._x
this.oldY = this._y
}

start = Path.shift()
end = Path.pop()
Tweener.addTween(myMc, {_x:end._x, _y:end._y, _bezier:Path, time:10, onUpdate:orientToPath, transition:”easeInOutQuint”})
————————————————————–

works, but wiggling the MovieClip at start and end of the tweening specifically when easing the tween.

Can’t find a solution for that.

Thanks again
