I've got a tween I'm using:


var dValue = Math.abs(old_value - new_value);
var speed = dValue;
var delay = 1;

this._tween = TweenMax.to(this, speed, {my_value:new_value, delay:delay, overwrite: "all", ease:SteppedEase.config(dValue),onUpdate:this.setTrailGFX,onUpdateScope:this});


Which isn't working in quite the way I'd hoped...


What I'd like to do is only have my onUpdate callback fire when I reach the new integer value, this calls a number of times (depending on the speed/dValue amount.)


I did also look into using roundProps ( for this.my_value) but this also didn't work in quite the way I want.


The problem is that the this.setTrailGFX function is quite expensive, so I only really want to call it when needed.


Any ideas about how to work this (or do it differently) would be appreciated!
