I recently joined and have read some very helpful posts and have got an audio file playing in synchronization with a timeline. What I need specifically is audio with a scrub bar being synchronized with a series of animations which have their own scrub bar.


In the code I have put together I have the audio playing and the animations running for the duration of the sound file and I have a scrub bar for the audio and animation which are synchronized together.


The problem I have is that the animations are not moving smoothly but are shaking back and forth. I think this is to do with the rate at which they are being updated and I believe things can be improved by using the TweenLite.ticker or the TweenMax.ticker but I am not sure of the best way to implement them.


Can you help me to smooth out the movement of these animations. The codepen is here: 


Many Thanks

I have implemented the ticker which has now smoothed out the animation but now it is finishing a little early. Not sure on why that is happening. Can you help?

Hi Pebble,


Welcome to the forums! 


That's a really nice start and setup. The codePen really helps, thanks for that.


You actually got it all going. Your only slip was overdoing it a tad.


You created a timeline, added the test animation and hooked it up correctly. But then, you added half of the timeline inside another variable and tweened that with the tick. All you had to do was to tween the whole timeline with your Update function.

. I think this is what you were looking for.
