different durations and delays for a single line of fromTo yoyo repeat repatDelay

I love the extreme chaining and custom animations you can make in just a single line of code. I was wondering if a repeating animation can be done like so:

 

object starts invisible, alpha:0

 

immediately begin to fade in over 1 second

wait and stay visible for 2 seconds

fade out over 3 seconds

wait 4 seconds for the animation to repeat

 

I used durations of 1, 2, 3, and 4 to make it easy to show that I want each leg of the animation to have its own duration and delays.

 

I imagine something like this below, but I might not even be close, or this might not be possible in a single chained command?

tl.set(object, {autoAlpha:0}).fromTo(object, 1, {autoAlpha:0}, {autoAlpha:1, duration:2, repeat:-1, yoyo:true, repeatDelay:2}).delay(4);

I think I may have answered my own question.

 

new TimelineMax().set(object, {autoAlpha:0}).to(object, 1, {autoAlpha:1}).to(object, 3, {autoAlpha:0, delay:2}).repeatDelay(4).repeat(-1);

 

This appears to work in my example, hitting all those durations and delays of 1, 2, 3, and 4. Do others agree this is correct or can I fix it or optimize it further with just fromTo or something?

Hi @Jimmi Heiserman

 

There are many ways to skin a cat! Using a single, chained statement ... you could execute delays by either using the position parameter, the delay property,  or by tweening to an already set value for the duration = to the desired delay. Here is a CodePen illustrating. Hope it helps!

Will absolutely do it!

 

And I see you meant "truly" one line! I thought you meant one chained event :)

 

I included a yoyo only because I caught a glimpse of it in your original code. With or without, you certainly answered your own question! Nicely done!

 

Here is a pen using your method

Thanks for showing the other way to do it too with pseudo delays and using a non-change animation as a wait timer. I cleaned up your codepen.io in a fork. I figured since we aren't actually tweening anything for those last 2 seconds, I made both the target and the vars an empty object. That's just preference though. But I did consider the yoyo:true you added to be a bug because not only do we not need it, it causes a flicker/overwrite around the second or third repeat because we don't really want to bounce backwards because we used two "to"s.

But again, thanks for that codepen. Seeing how others do something expands our knowledge on this. Tweening is like a chess game, with some many ways to win, and you get better by seeing others moves and strategy you may have missed.
