Can AS2 and AS3 be used at the same time?

[C.S. Murphy]

Hey guys,

Haven't posted here in ages. I have a question about AS2 and AS3.... basically, I'm trying to breathe some life into my site but my buttons are created using AS2 and the component I just purchased for my site runs only on AS3. Is it possible for various sections of my site to contain both programming languages?

Is there a reverse compatibility when it comes to programming languages?


Many thanks!

There is reverse compatibility with *some* programming languages, but I don't think AS2 and AS3 are in that category.  For example, any C program written will also run in a C++ environment, but I believe they have changed some syntax between AS2 and 3.

From Adobe's website here:
"A single SWF file cannot combine ActionScript 1.0 or 2.0 code with ActionScript 3.0 code. "

Though, they have added this migration guide for what major things have been removed/changed.
Hope it helps!

I think that actionscript 3 was almost completely re-made. It uses a lot of similar commands, but odds are that you would have to type every line slightly differently to acheive the same effect in both languages.

I appreciate the info guys...


Thank you much!

From memory, AS2 code is actually mapped back to AS1 when it's compiled, however AS3 is a completely new codeset and all of the internals are very different. Unfortunately, it'd be a case of upgrade your AS2 or downgrade your AS3.
