What it says on the tin.


Why do I get a "is not a function" error when trying to get the total progress of a staggerTo (or From) tween?


Am I being thick here or is this a well known thing?

Hi and welcome to the GreenSock forums,


Thank you for providing the demo. Very helpful.




The reason for the error is that TweenMax.staggerTo() creates and returns an Array of tweens.

try console.log(t2) in your code.



Most people don't realize this until they try to call a method like play() or restart() or progress() on a staggerTo().


If you have a staggered effect that you need to track the totalProgress() use a timeline like

var tl = new TimelineLite();
tl.staggerTo(obj, 1, {x:200}, 0.2);

Let me know if you need more help.

Most exquisite behaviour.


Thank you sir. This place looks like a good gathering of nice people. Very welcoming ;)


BUT! With the information you have just provided...


One could argue that one can reach the totalProgress of a element with:

var t2 = TweenMax.staggerTo([{}], 1, {});
console.log("t2a:", t2[0].totalProgress());

Does not seem to be mandatory to have a timeline.

Yup. if you just need the totalProgress() of one of the tweens then that will work fine.
