Subject Re: Starling + Flex
Date Sun, 21 Oct 2012 17:34:38 GMT
The current Flex Framework is a very large code base that contains 50% code
written for AS2 and then ported to AS3 and 50% code written with extra
overhead to support Flash Catalyst.

All of the code is written to work against the Sprite/DisplayList API.

A straight up port will bring all of that baggage with us, and, because of
the interdependencies in the code that is a vestige of what was required to
get AS2 performance, it will be hard to do such a port in phases.

I've been saying from the beginning of Apache Flex that it is time for a
next-generation framework designed to be ported/transcoded/whatever to
different targets, which could include AVMNext/AS4 if it proves worthwhile,
but again, AVMNext doesn't have a good story around accessibility, so while
you could write some simple UI to get someone to pay for your game, I'm not
clear it upscales to true internet applications.

What will that look like?  I have some ideas, but I'm not totally sure yet,
I hope to have some discussions on this at 360Min before bringing the ideas
to the list.
