Hi, one thing I'm investigating in parallel among other things is about how to make animations easy in Royale. We have already some infrastructure in the Effects.swc, but this library has the great point to be very oriented to Royale with beads and although I didn't tried in SWF, I suppose is working for Royale JS and SWF.
In the other hand there's other great JS frameworks out there that brings many options to this field, but the problem will be just that: only JS. For me the better option would be to create a new library to be used with UI sets, that brings the power of some programatic JS lib out there, and concentrate in the JS part in the short term but left open to SWF for others that want to bring that part to it. I think many things nowadays can be done in CSS, or JS or combination of both. And I like the idea of having most of this in CSS if possible. I think Web Animations API has both options animations via JS API and via CSS I was interested in Framer [1]. I always liked it. But seems Framer has turn towards React. Today I could have a call with Framer people to ask for possibilities to make some Royale lib (as we did for MDL) for Framer , since although the older version is OS, the newer is still not, although they want to make it OS. The problems is Framer is very React oriented, so I think is not a real option. Then Framer people kindly point me to Popmotion Pure [2], that seems the point from where Framer was created. I still need to dig a bit into this, but seems a good option (for what I see). So, one option could be: a) Use Web Animations API: I used this already in Jewel Wizard, and maybe this is the real option of future b) Use Popmotion c) Use GreenShock [3] (I think others here like Harbs pointed to this. I still didn't look at it, but I think is a payed lib, so maybe not the better to use) What do you think about it? I'd like what others think about all of this [1] http://framer.com [2] https://popmotion.io/pure/ [3] https://greensock.com -- Carlos Rovira http://about.me/carlosrovira
