Not magic, just a different kind of science.
You 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...
MorePrologue A coworker of mine recently told me that interfaces were for him, a purely academic exercise and that outside of a CS degree, he has never used one. I almost slapped him, railing the age-old battle cry, "favor composition over inheritance!" but all I could do was let out a frail whimper. You see, […]
MoreI'm not a C programmer by trade. Or C++, or Objective-C. However, I've been working with the whole dang family lately. Clearly there's been some inbreeding. Anyway, for my iPhone adventures, I'm using Box2D--the real C++ implementation, which means that I've got to use some 'Objective-C++' at some point. The problem with that is how […]

MoreI've been working on Itsy lately, because, let's be honest, my fire demo was only marginally cool. Now, however, even people who aren't my mom may tell me it looks cool! Check out my new fire: Now that's an improvement. On to the bonus tutorial. [WARNING: Bonus content ahead.] In Scorch3d, I wanted to add […]
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 […]
