Advanced: The embarrassment of learning As2.0 and AS3.0

From the Macromedia to the As1.0 reform to AS2.0, this process looks a bit longer, from FLASHMX to flash mx2004 to Flash 7.2 to Flash8. Their core ActionScript is as2.0. In Flash8 just released not long time, Macromedia and tight shelomith drum of the launch of the FLASH9 preview version, we all know the Adobe release of the preview version can be compiled AS3.0, and As3.0 tested its speed can be said than The previous as2.0 is 10 times times faster. Holding the as3.0 compared with As2.0, although some things look familiar, but it looks like a rewrite of a new language. And then there's the Adobe Flex 2.0 builder. Flex SDK. Let a lot of people at a loss, facing the as3.0 and Flex 2 so strong attraction how to choose.

Of course, there may be a different situation here, take me, I have learned that As3.0 no matter in any respect to go beyond As2.0, also want to spend time to study to learn As3.0, But also face daily As2.0 and As1.0 mixed work, is deep as2.0 or learn new as3.0? It's like knowing what FLASH8 can achieve. But it is not possible to use it, because the customer does not agree to output flash8. This looks like a pretty awkward and depressing thing. I'm sure there are many people who feel the same way. Make a personal point about this:

Personal Opinion:

1. If you have just begun to learn as. Then it is recommended that you learn from the basics of As3.0 variables, loops, and so on. No need to think as2.0,as1.0 any more.

2. For the old designer. If you're used to programming on the timeline, then I think it's enough to be proficient with as2.0, because no matter how the flash version changes, it will be backwards compatible. Although as3.0 can also be programmed in timelines, you may find that you have previously used gotoAndPlay (). Loadmovie () and so on are no longer valid, If you have as3.0 developers inside your company, you'll need to understand As3.0 's general programming to work with as3.0 developers.

3. If you are a pure, fanatical flash developer, then all you need to do is change quickly and move quickly from as2.0 to as3.0. If you want to learn more about Flex 2. Then you might want to learn java. asp.net wbservice and so on. Oh, look very tired ah.

PS: "Greener", who want to learn the most advanced, most useful. What time is it? A principle, with the least amount of time to learn from the most available.
