  actionscipt to after effects

  Posted by Chompy on September 10, 2007 at 9:40 am

  Hi Folks,
  I’m aware of the new functionality involving combining flash and after effects, but I’m still obsessed with the idea of translating some actionscript code for use in after effects.

  I’m not even really sure what I’m asking I’m afraid – maybe just a reference to the different syntax? But It’s just that I know some sh8t hot flash coders and wondered if their skills could be applied to after effects. There are so many examples of code driven animation out there for flash and I’m desperate to see if there’s any crossover. I’m sure there must be some really exciting techniques to be discovered!

  Any suggesions???
  cheers

  Well, both languages are based on JavaScript, but there are some fundamental differences that make translation of all but the simplest Flash animations to AE tricky.

  The big one is that expressions start fresh at each frame, with no history of what has happened before (i.e. there are no persistent variables). In Flash, you do have persistent variables, so you can update your animation at each frame by, for example, just incrementing an element’s position. With an expression, you can’t even get at the current value – only the pre-expression value is accessible. This difference alone really complicates things.
