Timelines - Tween containers #914

Chaining multiple tweens, so each one starts after the previous one finished is currently quite fiddly - you basically have to start a new tween from the old one's onComplete handler - not very convenient. It's also currently impossible to create a more complex animations/sequences and play them back and forth, change their transition, etc.

My proposition is to introduce a container class for storing tweens (and other containers) - a Timeline class. They have something like that in this Java lib: http://www.aurelienribon.com/blog/projects/universal-tween-engine/

It's really a must have if you plan to do any more complex animations, so I think this would make a great addition to Starling's tweens.

Yeah, but the problem is this is not a part of Starling and Starling's tweening engine is already pretty solid, it just needs timelines.

Thanks for the suggestion! I can totally see the sense in that. Anybody who wants do see this, please vote!

BTW, just for reference: it's by far not as elaborate, but there actually is a way you can chain tweens together in the current API: via Tween.nextTween.

Tween.nextTween() is OK, but it's not as functional as timelines. It's, for instance, much more inconvenient to pause a complex animation created with nextTweens than to pause a timeline-based one.

If you need any more references, I created something like that some time ago (based on your Tweens), but it's still inconvenient to use, if it's not a part of Starling:

Thanks, I will definitely take a look at that! :smile:
