RE: [Flashcoders] Try... catch......
One thing to note, is that try,catch(e:Error) is expensive for the AVM because
it has to Throw an error.
Maybe not for this example or whatever you're creating, but it's something to
keep in mind for later.
I see a lot of code we receive riddled with that as a way of hiding run-time
errors AVM1 style.
Just something to note,

I regret my one word answer because while it answers the question, there's a
question of good practice to consider.
Putting "return ball;" as the last line doesn't really help the casual code
reader, because I need to really look hard at the code to realise that if
ball is not explicitly set elsewhere the return value will be null.
However,
catch (e:TypeError ){ return null; }
explicitly shows that if the exception occurs the function will return null.
There's even a good argument for having "return null" at the end of the code
too, since only one exception will explicitly return null...
It's always better to have explicit code rather than try and save a
statement or two. We've all been down the "smart" code route though. Guilty
as charged.

Re: [Flashcoders] Try... catch......
I might be wrong, but I think hanlding an exception / error is not the
expensive part.
The expensive part is throwing, as you said.
But, if you have:
var container:Sprite = null;
container.addChild(child);
The error will be thrown, whether you have a handler for it or not. The
"cost" here is that the player has to unwind the stack looking for a
suitable catch block to handle the error, jump to that block and then get
back to where it was.
In fact, I think handling the error right away should be less expensive than
not catching it or catching it further down the stack.

[Flashcoders] Creating MXP with Flex Builder?
I'm development a library of interactive sound effects in Action Script 3 using Flex Builder. I've got loads of experience with audio coding on various platforms in various languages (especially C++). However, I'm relatively new to Flash development, so I have some (perhaps naive) questions about how to package the library. Perhaps some of you can help. Until now, I've been thinking of packaging the library as a SWC, but after some investigation, it seems that flash components are normally packaged & sold as MXP files, e.g. on sites like flashloaded.com. As far as I can tell, Flex Builder doesn't provide any way to directly create an MXP. Is there some extra plugin for Flex Builder for creating an MXP? Or is there some separate tool that can create an MXP from a SWC? I've seen the Adobe Extension Manager mentioned in the context of MXPs... but from what I've read so far, it sounds like it manages loading of MXPs, rather than their creation. I've seen some docs on MXI files, which appear to simply be XML files for defining what goes into an MXP... but I still haven't figured out what tool will read in an MXI and files to which it refers to generate an MXP... any tips would be most welcome! I'm developing on a Mac, btw, but can easily switch to using Windows if the tools available on Windows are better. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
