working example of "onInterrupt" callback

[isladjan]

Hi to all, 

 

I'm trying to learn gsap 3.x, but i have a problem with overwrite.

 

Can anyone show me working example of new "onInterrupt" callback?

 

Or there is some other way in GSAP 3.x to identify when (or if) overwrite between tweens is happen?

 

Thanks,

isladjan

Hey isladjan, welcome to the GreenSock forums!

 

This is a good question. Sorry, we're still in the process of updating our docs (it's a long process to document all of the changes and new things!) so onInterrupt is not in there yet. 

 

The GSAP 3 Release Notes say

Quote

onOverwrite was removed in favor of a new onInterrupt callback that fires if/when the tween is killed before it completes. This could happen because its kill() method is called or due to overwriting.

This means that onInterrupt only fires if the tween is effectively killed, meaning something like .kill() is used on it or another tween affecting the same target has overwrite: true. 

 

It might be worth observing how the different overwrite values affect your animation:

Are you trying to achieve something specifically? Maybe some context can help you figure out the setup that you need.

thanks Zach  for clarifying this to me and for quick response.

I have a problem with property: repeatRefresh, i can't make it work. I'm trying to make a demo in which the svg paths will go in random directions using the new GSAP 3.x Utility Methods. I thought first the problem is with overwrite, but it's not.

Cool animation! I like it.

 

Very good question. repeatRefresh currently only works when the tween itself is what has the repeat property on it. Since you're repeating an entire timeline, the individual repeatRefresh isn't applied. 

 

To work around that, you could create a new set of tweens for those that you want to repeat with different values after the timeline has completed. I also set the progress to 0 of your CodePen timeline and invalidated it because it ends up in a different place (the ornaments timeline ends up in the same place as it starts so you don't need to do that).

Side note: you can use the delay or repeatDelay properties instead of empty tweens if you'd like.

Perhaps GSAP 3.x documentation is yet not perfect, but gsap forum is.

 

Thanks again Zach, that's exactly what i was looking for. You saved me a lot of time. I will accept your syntax and advice.

As of GSAP 3.1, you can now use repeatRefresh on the timeline itself instead of having to create a new timeline each repeat!

Thanks Zach,

 

I update the code, and repeatRefresh works now perfectly on Timeline.

 

just keep up the good work :)
