Droste / Escher Effect in AGAL

by Devon O.· December 31, 2015· in Actionscript, Shaders· 0 comments tags: agal, effect
One last bonus post for the new year, seeing as how I remembered I had a blog. This is really just a snippet I would ordinarily post on Wonderfl, but Wonderfl seems not to be working for me lately (if anyone wants to check out my Wonderfl profile and let me know if they can view any of my posted codes, I’d appreciate it. But I can’t). [crayon-61743f803c48f682835890/] Happy New Year!

Ending the Year with Dynamic Multi-Pass Shaders in Starling

by Devon O.· December 31, 2015· in Actionscript, Shaders· 6 comments
So, the last day of 2015 and, I believe, just my second post of the year. I think there’s some law which states you have to make at least two blog posts per year to legally say you maintain a blog, so I’m a bit pressed for time. I would love to say the reason for my absence is all the work I’ve been doing on a secret project which has been taking up all my time – and that would actually be at least partially true. But, let’s face it, I’m a bit of a lazy man, and also have to wonder if anyone, besides myself, that is, actually still reads Flash blogs these days. Hopefully someone. A Little Bit About Project X For the past 3 years or so, in my spare time, an hour here, 2 hours there, I’ve been working on a bit of a casual mobile game. While I’m not at the point of releasing or even revealing too much about it, I will say you will eventually get the chance to play a big-nosed bug on a motorcycle (if anyone’s actually able to guess the game title from that little tidbit, I’ll give out […]

Base Mobile Tasks .ane and a Few Tips

by Devon O.· March 29, 2015· in Actionscript· 0 comments
Admittedly (and rather pathetically), it’s been so long since I’ve posted anything on this blog, I’ve nearly forgotten how. I am still around, however, and still, after the innumerable deaths of Flash over the past decade and a half, primarily an Actionscript developer. Being an Actionscript dev these days, though, really means being an AIR developer. And being an AIR developer, really means being a mobile developer. And being an AIR developer who works on mobile apps means at the very least occasionally getting one’s hands ‘dirty’ writing native code packaged as an Adobe Native Extension or .ane. If you’re reading this (for the most part) Flash blog and don’t know what an .ane file is, I’ll just assume you’ve been living under a rock and just move on. Having worked on several (Android only) ane files at work now, I thought I’d share a few tips and tricks I’ve learned along the way. Some of these are Android specific and some generic. Don’t package support files in your ane. If you are writing an ane (just for example) for Google Analytics, by all means include the GA sdk code. But if your ane requires, say, the Android support v4 .jar […]

Some Photographic Shaders

by Devon O.· September 13, 2014· in Actionscript, Shaders· 12 comments
A couple weeks ago I was contacted and asked to write some filters for Starling that could be used in a mobile camera application. To be honest, I’m not sure what’s become of the app as I’ve lost contact with the developer, unfortunately. A part of the deal, however, was that I eventually open source the filters, so I’m going to go ahead and do that now. So, to my Starling Filters repo on Github, I’ve now added seven new photographic effects: AnselFilter is a highly configurable way of making black and white images. BleachFilter will bleach the color out of images in a fairly interesting way. BloomFilter a relatively standard bloom effect with adjustable color. LomoFilter does a bit of toy camera/Lomo/Vintage color adjustment. NoiseFilter will add a custom amount of grain/noise to an image. Animating the seed parameters can produce a nice static effect. TiltShiftFilter will produce a decent tilt shift blur. To be effective, this filter requires multiple passes, though, so probably isn’t that useful in performance critical situations. VignetteFilter creates a standard vignette effect with optional sepia colorizing. I also sat down and created a filter browser demo app thing so that you can easily see how different […]

Animated Particles, Books, and Code – It’s a New Year

by Devon O.· January 01, 2014· in Actionscript, Flash, Life· 3 comments tags: particles, starling
2014 It doesn’t even sound real. Like an unreachable year in an 80’s sci-fi b movie. And yet, for better or worse, here we are. Seems my last post was quite some time ago (I think WordPress has had 16 releases since then) and a bit negative (bug report), so it’s time to start the new year off right. Animated Particles First on the agenda is something I’ve been meaning to do for awhile, but just never got the time until this Christmas/New Year’s holiday. Now, I really love the Starling particle extension. I mean, hell, who doesn’t love particles? But I always thought it would be nice if the particles could be animated (think flocks of flying birds or schools of swimming fish), so I sat down and added the possibility. First, the downside. I was hoping I could simply extend the current Starling particle extension and tweak it a bit. In theory this would be possible. Unfortunately, in practice, the properties and methods that needed tweaking were private class members. So, unfortunately, I had to basically duplicate a good deal of the code. First I just copied ParticleSystem.as into a new class named OpenParticleSystem and set the private […]
