adding an event callback after instantiation

[mrkos67]

I've created an instance of a TimelineMax, and now I want to add an onUpdate callback after it's been created. The only thing I can find to set up event callbacks show it is during the instantiation. Is there a way to do this?

Hi mrkos67 

 

pls check the .eventCallback() method : http://greensock.com/docs/#/HTML5/GSAP/TimelineMax/eventCallback/

So I just found that after I posted, but it doesn't work as intended. I add an "onUpdate", but it only fires when the timeline's play function is called.

Okay, I figured it out. My timeline didn't actually have a duration. I thought by setting a label at a specific time in the timeline, it would give that timeline a duration. So I had to put in an empty function to actually give it a duration. All is good. Thanks for your help!
