Hi Matthew.


Hope things are well with you.


hmm, I'm not exactly sure what the desired result is supposed to look like but I noticed 2 things.


1: the timeline's that you were trying to restart had no duration.


 console.log("on app start fireTimeline duration = ", fireTimeline.duration())
 console.log("on app start resetTimeline duration = ", resetTimeline.duration())

both of those logs gave me 0.


The reason for this is that you were adding functions to your timelines NOT the timelines that those functions created.


These 2 lines were to blame



in order to call the slingFire function and get its returned timeline you need to invoke it with () like:


same for

I also noticed that some overwriting was occurring. This means that 2 animations were running at the same time fighting to control the same properties of the same target at the same time. When this happens the first tween gets overwritten (killed) which can cause problems if you try to play that animation again.
I put in some logs to help you find the troublesome animations
TweenLite.onOverwrite = function(overwriting, overwritten, target) {
  console.log("overwriting tween", overwriting)
  console.log("overwritten tween", overwritten)
  console.log("overwritten target", target)

You can read more about onOverwrite here: http://greensock.com/docs/#/HTML5/GSAP/TweenLite/onOverwrite/


Here is a fork of my demo with some updates
