Not magic, just a different kind of science.
Virtual. It's a language feature that I've decided I have understood incorrectly for awhile-- but it's not completely my fault... See, a large part of my professional career has been in Java Land where the virtual mechanism is a quiet little assumption sitting off by itself in the corner. All methods are virtual by default […]
MoreAS3 is certainly not strictly classical (there's a Class::prototype object for Pete's sake!), but it's got a lot of the classical garb. Anyway, today I was rummaging around in a class in our codebase called FunctionUtils and I decided, whilst fixing a few things, why not add a couple of the fun functional constructs?! Function::schönfinkeling […]
MoreYou know how Cocoa classes generally have static methods that serve as factories? return [NSArray arrayWithObjects:obj1, obj2, nil];return [NSArray arrayWithObjects:obj1, obj2, nil]; That's a dumb example, especially now that you can do @[obj1, obj2], but why not do the same in AS3? For instance: return TransactionResponse.FailedResponse();return TransactionResponse.FailedResponse(); This would replace something like: var response:TransactionResponse = […]
MorePerhaps the least helpful MXMLC error message yet: public function log(level:int, message:String, ... rest):void { trace(format(level, message, ...rest)); }public function log(level:int, message:String, ... rest):void { trace(format(level, message, ...rest)); } Apparently calling a function with ...rest on accident will present this compiler error...

MoreE4X in AS3 is flippin sweet. In fact, when I work in Flash I generally use XML over JSON or any other serialization or data storage solution because I can use E4X queries. I know several developers that embed Flash objects in web pages just so they can parse XML with it and pass it […]
MoreI've been fooling around with the Away3d 4.0-beta lately (for FP11!). I wrote a quick demo--it's using Box2D on the XZ plane, and I'm faking the Y physics. Try it out! Arrow Keys move. Spacebar shoots. Enter jumps. If you time it right, you can jump over the wall! Link here.
MoreVery recently, I needed an object to shoot into the air and fall realistically, but I didn't want to import a tweening library or a physics engine. What I needed was some sort of parametric equation that would act like gravity... What would this mysterious equation be... Oh, that's right, Newton's equation of motion for constant […]
MoreWhether or not you agree that JavaScript is (or can be) a functional language, we can all agree that spelling functional with a 'k' makes it look German. And downright funky. But enough with stupid comments. Apparently this thing called HTML5 is a flash killer. So in the interest of science (and job security), I […]
