How Wonderfl

I’ve been playing around a little with the online Flash building tool, Wonderfl. If you haven’t seen it already, I urge you to create an account and have a go. You can browse the weird things that people have created, fork other users’ code, or write you own from scratch and see the results compiled online in realtime. It’s a great way to learn graphics coding in AS3 I reckon.

Audio visualiser

I finally got around to making a simple audio visualiser, something I’ve been meaning to do for a while. If you have a microphone, simply click ‘allow’ below and put some music on. You may need to play with your micrphone gain though, just right-clic, go to ‘settings’ then click the micrphone tab and drag the ‘record volume’ slider up/down.

Migrate to AS3 now!

Much as it pains me, I still develop in AS2 when it’s absolutely necessary – usually because a legacy application needs maintenance. But I was never a big fan of AS2; its quirks, the weird workarounds and its ‘almost but not quite’ OOP nature always annoyed me.

For those still clinging to AS2 like a comfort blanket, daunted by new-fangled syntax and the loss of some of AS2’s most trusted old arcane method, fear not! Help is at hand in the form of this handy AS2 to AS3 migration guide.

In many ways, AS3 is actually simpler than AS2, because it retains less of the AS1 legacy that plagues AS2’s structure and behaviour. We should all be developing in AS3 now and drop AS2 like a bad habit. That’s not because I’m some kind of code fascist; I find that the development and maintenance of projects built in AS3 just seem to go smoother – but the enforced use of the proprietary, often clumsy frameworks I encounter in some of my contract placements is another story altogether.

Flash 10 Matrix3D demo

I quickly cobbled together this little demo using the new native 3D transforms in Flash 10. Alongside the regular transform.matrix property, DisplayObjects now have a transform.matrix3D property, which controls its appearance in 3-D space. It’s pretty easy to play with in Flash CS4, without any coding knowledge – I can’t wait to see a version of GTA built using this 🙂

Webcam controlled motion

I started playing around a little more with my Webcam and extended my previous motion detection example – this time to control the camera of a virtual 3-D space from motion detected in the user’s Webcam. It detects motion area and general direction, albeit with dubious accuracy, but you get the idea.

Due to popular demand, I’ve posted the source code for you lot to play with. It contains the FlashDevelop project file (it’s compiled with the Flex 3 SDK) and my cut-down 3-D engine, Pants3D 🙂
