vars property "onReverse"

[Romanus]

Hello! I need the vars property "onReverse". But in the documentation I only found "onReverseComplete"

I want to call a function when reverse starts. Is it possible?

Typically an onReverse isn't needed because all you need to do is put your function call wherever you call reverse() in your own code, but we do have a helper function in the docs for exactly what you're asking: 

https://greensock.com/docs/v3/HelperFunctions#onReverse

 

Does that help?

I can not. onUpdate returns undefined to the console. What am I doing wrong?

Hi,

 

It won't work if you don't actually use it. Take a look at the link Jack provided in order to see how the helper function is implemented.

 

Here is a fork of your codepen:

Hopefully this helps.

Happy Tweening!
