I had said I’d post the AS3 version of localToLocal and here it is! I’ll be adding some modifications for Flex2 stuff as I get more familiar with it, but this works as it did with AS2. I’ve tested with Flex2 and basic AS3 apps and works very well.
I included the entire class here, use it as you will – Rock on \m/

I added an origin:Point argument to pass through incase you were converting mouse coordinates

Hey John
Is this any use to you. It’s a hacky version of your localToLocal with a method for 3D added (local3DToLocal3D) – I needed one myself. I took out the origin Point because it wasn’t relevant to my needs – but I hope it will be of some use to you. Thank you very much for your original and very useful work on localToLocal, it got me out of the crap a few times.
You’ve probably already done this, so sorry if it’s old news:

Thanks, this function helped solve my confused coordinates.
