So I’ve decided to retire the Action Script section of my website. I don’t really work with Flash all that much anymore and to be honest, I’m getting quite rusty at it. The posts will still be available but I won’t be adding anymore moving forward.
I have been creating a code base for a Screen Manager system that I am using for an iOS app I am building in AS3. I wanted to create a dynamic way to reference and instantiate classes that represent each of the Screens in the app so I can reuse this for other applications in the future and to make it a lot less code intensive.
I setup a series of static variables that held string names to represent each of the Screens in the application. Then when I want to create the screen and add it to the stage I use the getDefinitionByName() method and pass the string name of the class. Continue reading “getDefinitionByName”
Garbage collection can be a big deal when writing complex programs in Actionscript. Not removing EventListeners is probably one of the biggest sources of AS holding onto memory it doesn’t need.
There is a very easy way to allow GC to handle your event listener clean-up for you when creating a new event listener – the useWeakReference argument.
Here is some standard code we’ve all done million times when creating a button:
var button:MovieClip = new MovieClip();
The two arguments are pretty straight forward the first is the event we’re listing for and the second is the function that is called once the event is fired, but there are actually 5 arguments that can be passed to addEventListener() here is the method definition:
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
the 5th argument (useWeakReference) is false by default but by setting to true, this eventListener will be automatically removed and freed for Garbage Collection when required.
Here is the new eventListener code updated to make use of useWeakReference.
This is the official website for Les Stroud’s newest television series: Les Stroud Beyond Survival.
The artwork was created by Luke Despatie & The Design Firm and I provided all the development for the project which included the creation of a Flash-based custom video player.
As the resident “web guy” for Les Stroud Productions, I was tasked with maintaining and improving upon the flagship website for Les Stroud.
Built on WordPress this site has seen many changes since I started working on it and is a great example of a “working” site. Many website are built and then left alone but this site is constantly evolving.
Whether it be the addition of jquery scrollbars and lightboxes, HTML 5 video fallback for iOS or Flash video on the homepage (with graceful fallback of course) this site is always looking to provide it’s visitors with a great user experience.

1180: Call to a possibly undefined method assignListeners.
1046: Type was not found or was not a compile-time constant: URLRequest;
Functions (aka methods) are the bread and butter of any application. Without them you can’t do much of anything. So I thought I would show you how to write one.
I am loving the stupid names I’ve been using for these posts. Pretty soon you’ll have no idea what I am talking about.
In my last post, I showed you have to create a new class and the topic of access modifiers was mentioned. I would like to expand on that topic and use it to introduce a new one for class creation.
Opening a URL in Action Script 3
Navigating to a URL in AS 2 was pretty straight forward.
As with most things in AS3 that has changed a fair amount. It is no longer one line of code. I’ll show you everything and then walk you through it Continue reading “Going Somewhere?”
