I don’t see anything wrong with programming and having the idea of looking ahead of the application.

The import concept for classes is enough and simple
to diagram your application.

I also hear a big buzz on “Flash” dying out cuz
too many developers can’t write and get use to as3.

Is simple, just practice

I took a look at the code, and I like the idea but it’s probably than events since events are native in AS3.

I always felt myself embarrassed working with the custom events in as3, every times looks like it’s a question of workarounds and tricky over the normal syntax.. resulting in bad code.

I worked on a project with c++ and Qt, where slot and signal policy are the normal way to dispatch events, and this kind of “porting” (if we can call it in this way) is exactly what i’m looking for.

Composition against Inheritance looks like an old fight, the point here is not which one is better in theory, but which is better in its implementation, and inheritance implementation of events in as3 wasn’t planned in a good way.

@Max:
I don’t know about Parsley, but there’s been a lot of work around combining Robotlegs with Signals:

cool Eric, let us know how it goes — its always difficult to judge from example code if it scales well to larger real world apps.

I have a massive project I’m about to start with. I think I’ll give this a try and see how it goes. Seems very cool.

I wonder whether this would play nice with frameworks that manage events. I find myself working with Parsley a lot lately and it would be nice if I could combine Parsley messaging and something like AS3 signals. That would remove even more of the event handling hassle.

Hey Peter,

I’ve seen the basic used in many AS3/Flex projects before where you have one custom event class with an Object property to avoid having to create a massive amount of custom event classes. However, that system doens’t have type checking, whereas this one (I suppose) does.

Looks promising and I will give it a try when I find the time…
