Re: [Flashcoders] Best Practices and optimization
I was lucky to addend Grant Skinner on FITC Amsterdam and he spoke about good/fast coding practice with Actionscript or: Quick as Flash. You can find it here: http://www.gskinner.com/talks/quickNL/ Interesting was his PerformanceTestClass. Some pre information about it I wrote on my blog: http://blog.dieanstalt.com/?p=480lang=en - Session 3 *Beatrix Kruemmer-Frau* Dipl. Ing.

There are a couple on the Adobe Web site. ActionScript 2 best
practices are at
http://www.adobe.com/devnet/flash/articles/as_bestpractices.html.
ActionScript 3 best practices are at
http://livedocs.adobe.com/flash/9.0/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Partsfile=1090.html.
If you Google ActionScript best practices you'll find a variety of
blogs and articles.
I can give you a couple that will speed up your code. First, use the
ActionScript classes as much as possible. They are compiled to native
code, and will run anywhere from 10 to 400 times as fast as any code
you can write, simply because the code your write gets compiled to
tokens, or bytecode, which then have to be interpreted at run time.
AS3 has a just-in-time compiler that helps, but there is still nothing
like native code.
In loops, always store the end condition in a register variable. For
example, instead of this:
for (var i:int = 0; imyArray.length; i++)
{
do stuff;
}
do this:
var arrLen:int = myArray.length;
for (var i:int=0; iarrLen; i++)
{
do stuff;
}
I know that runs faster in AS2. I haven't run tests in AS3, but I
would guess the JIT compiler would speed up either way of doing it,
but the second would still be faster.
Cordially,

Yes, I will be doing a lot of this. :)

Perfect. I had been doing it the worng way in some of my files.
I will be making this change immediately. Thanks for the laymen eg.

Every little bit helps. I plan on making a collection of the info I
have found.
Putting up a page on my website to find stuff like this.
Thanks again,
Best,

[Flashcoders] Best Practices and optimization
Hello, Sorry if this is a repeat. I lost all my old emails. Is there a document or website or page on adobe that I can go to that has all the best practices for coding in AS2 and AS3?
