Flashtip : Zoom in a clip to a specific point

Januar 27th, 2009 • flash, math, snippet

Imagine you have to zoom in a mc on a specific point.
This math snippet works fine for me (I used TweenLite in my Code):

var tmpEndX : Number = ((spr.width)-(width*scaleFact))/2;
var tmpEndY : Number = ((spr.height)-(spr.height*scaleFact))/2;
 
var tmpXShift : Number = (mouseX-(width/2))*scaleFact;
var tmpYShift : Number = (mouseY-(spr.height/2))*scaleFact;
 
TweenMax.to(this, 0.5,{scaleX : scaleFact});
TweenMax.to(this, 0.5,{scaleY : scaleFact});
TweenMax.to(this, 0.5,{x : tmpEndX - tmpXShift});
TweenMax.to(this, 0.5,{y : tmpEndY - tmpYShift});

I have been trying to adapt this code to zoom into a quarter of an mc that contains a circle graphic but I haven’t had any luck. Lso I tried messing around with your example but no matter what I do the movie always seems to publishes the same results
