Many people in the big corporations thinks now it’s time to move to AS 3 their oldies (I heard of people still using AS 1 code). But seems they are only interested in quick transcodings (concept which isn’t possible, at all, unless we are talking about 10 lines of code).
In Pescados Software we use AS only as a tool, so we moved to AS 3 when we needed it, but allways for new projects. Re-usable AS 2 code was finally thrown, as most of times we found it wasn’t so “re-usable” at all. I think AS 3 is a good starting point to make new “solid” stuff. Although I’m not specially satisfied with the performance and “features” of the newer versions of Flash Player, I think AS 3 is a pretty decent language which many people coming from other programming languages (such as Java or PHP) adopted easilly, and others like us (more in the “design side of Flash”) can adapt-to, coming from the background usages of AS 1 and 2.
Still, from the end-user point of view, I don’t see many advances (watching silly HD videos in Youtube is no more than watching silly videos at all, only to mention one of the best new features of the latest FP versions, quite unrelated to AS 3 at all). If we spend the new power of AS 3 creating special effects (which aren’t so special at all), I will feel like a monkey with a gun. We must evolve and create the web 2.0, before the web 3.0 arrives so soon.
