I'm trying to tween a Raphael set:


var atomH1_1 = paper.set();

var atom_Circle1 = paper.circle(10, 10, 25).attr({id: 'circle1','gradient':'70-#00CC00-#00FF00','stroke-width': '0'}).data('id', 'circle1');

var atom_Circle2 = paper.circle(20, 20, 25).attr({id: 'circle2','gradient':'70-#0000CC-#0000FF','stroke-width': '0'}).data('id', 'circle2');




tween1 = TweenMax.to(atomH1_1, 0.3, {raphael:{'tx':100,'ty':100,'scaleX':0.5,'scaleY':0.5},ease:Power1.easeInOut, onComplete:nextStep});


But it seems it triggers an error in GreenSock ():

TypeError: c is undefined


Line 13


When I use the Raphael animate, it works fine, (but that's not what I'm looking for):

atomH1_1.animate({transform: "t100,100"}, 1000);


Is it not possible to tween Raphael sets? Or what am I doing wrong?



EDIT : I sort of solved the problem by using multiple targets in GreenSock:


var mySet = [atom_Circle1,atom_Char1];

TweenMax.to(mySet, 2, {raphael:{'tx':100,'ty':100},ease:Power1.easeInOut});

Yep, GSAP's RaphaelPlugin doesn't support Raphael "sets" like that but you found the exact solution I'd recommend :) Good job.


For the record, the error was because the "set" doesn't have a "matrix" value (since there are multiple objects in the set, all with their own matrix). Thus when the RaphaelPlugin tried to figure out how to do the transform(s) on the object, the null matrix tripped it up.
