Interactive Generative Art Series – 05 – wild anchor

Posted on February 10, 2011August 29, 2014 by Evan Mullins

While in the previous step (Generative Art 04 Using a target other than the mouse) in this generative actionscript art tutorial series it was cool to see everything move on it’s very own, it seemed a bit slow or fake, or maybe just plain uninteresting. Tinkering with the color, I thought if we set a minimum and maximum value for each red green and blur we could control the colors a bit more and still let them be generative. Plus I wanted the anchor to move a bit more and thus paint the curves and lines in a more interesting fashion. To do this we ramp up the range of the change rate of the anchor velocity. I really enjoy this example because it is faster, so we get more of those sweeping arcs, but also when the anchor slows down we get some very delicate curves and twists. With just a couple changes from the last example (which frankly seemed a bit chaotic), now I’m starting to see for the first time how to set some controls in the code which will lead to a visually appealing and still randomly generative result.

For some reason I find it gratifying that the final swf is still a mere 2kb and change. Perhaps all this current focus on HD and 3D gives us the sense that to be good it needs to have a large footprint. Sometimes the magic or value is in how much you can accomplish with less (less is more)

Interactive Generative Art Series – 04 – anchor

Posted on February 7, 2011August 29, 2014 by Evan Mullins

Thanks for keeping up with this random generative art series. I know I’m having a ball just playing with code one step at a time. To watch each iteration, I was getting tired of drawing with my mouse to see the generative art, and as others had pointed out, in order for it to truly be generative, it shouldn’t depend on me moving my mouse. So instead of using the mouse position as my target anchor, I created a new node named anchor. This anchor I’m animating with simple random brownian motion which I’ve blogged about before. It just meanders along the stage as it pleases and the other ball will “chase” it just like it chased your mouse in the previous examples. The part that gets exciting is that my anchor wraps from one side of the stage to the other, while the ball does not. One second it’s target is far right and the next it switches to far left, this makes for some really interesting paths and lines. Experiment with the velocity of the anchor in lines 47 + 48 to see interesting effects. One thing I’m beginning to notice however is the performance of the little app gets a bit slower the longer you let it run, perhaps I didn’t realize it before since I didn’t have the attention to keep moving my mouse and watching it follow, now that it truly is generative (and less interactive btw), I watch it longer (seems kind of backwards to what I’d expect).

Note: in this example I have the anchor ball visible, as well as the other ball, but for an actual production, I’d have them both hidden and the lines just appearing. I prefer it that way but though you’d better see what was actually happening with them visible, even though it kills some of the magic. It’s like watching a magic trick when you already know how it’s done.

Interactive Generative Art Series – 03 – Gradient Colors

Posted on February 4, 2011August 29, 2014 by Evan Mullins

With the full range of colors randomly available to me, I wanted to get a more fluid randomly created color. I see the hard line breaking one color from the next in the generative art 02 random color experiment. I wanted to have the lines drawn between my 2 points to be a gradient of two colors rather than solid color followed by solid color. In this attempt at a smoother color transition, I needed to better understand the gradientBoxMatrix and createGradientBox. I knew visually what I wanted to accomplish but had to brush up on the docs and then experiment a bit to get the math right. The hard line color change still shows in places, but it’s only when one line is short enough and then is overwritten by the beginning of the next line, so technically it’s doing what I intended, but visually it’s still not as gradual as I was wanting. I could toy a bit more with the rate of color change, but I feel pretty accomplished after having figured out that trigonometry and arc-tangent.

Interactive Generative Art Series – 02 – Random Color

Posted on February 1, 2011August 29, 2014 by Evan Mullins

With this example we’re taking a look at having randomly changing color. I liked the limits to the color in the last post, but couldn’t help myself and wanted to see it with the full range of colors to command. Also, I wasn’t a huge fan when the color would “wrap” and jump from one color to the next so fast. I wanted to use the same velocity (rate of change) principle from the line width experiment but apply it to color, and have it meander aimlessly among all colors. I created a color object to store a value for each of the RGB color values, and then had each element of the color change independently. I didn’t want to complicate my loop function so I made a new function that is called from loop that steps along to a color which should be pretty close to the previous color. I enjoy the range, but as I expected it was a bit much, or too many colors at once, also the step is a bit too fast at times it seems.

Interactive Generative Art Series – 01 – Color

Posted on January 31, 2011August 29, 2014 by Evan Mullins

After updating the line width to be still random, but more of a gradual step in variation (in the first experiment in this series), the second most obvious edit to the original in this generative art series is the color of the line. While it would be pretty simple to update the code to use any one solid color in place of the black, I wanted the color to vary over time. The simplest way I know to achieve this is to create a variable to hold the color value (as a number) and then change it over time. So here, I have a color chosen at random and just increment it every time the loop function executes by 1024. I chose this amount because it would loop through and eventually get back to where it started while restricting the color scheme. I think it brings a lot to the design to have color – and I especially like how it randomly creates a color scheme and sticks to it. Totally random colors may look a bit much, while problematically it’s not too difficult to get, it may be difficult to look at once it’s created. Above are a few screen shots of the random colors generated:

You’ll see if you’re following along that this only add 2 lines of code from the last version. We simply create and instantiate (with a random value) the color variable and then apply it in place of the black to the lineStyle and simultaneously increment it.

Interactive Generative Flash Art Series – 00 – Line Width

Posted on January 28, 2011August 29, 2014 by Evan Mullins

After seeing the source code in the original experiment, I found myself wanting to play with the code. I saw many elements of the lines and actions that could be interesting to explore. This is the first in a series, of experiments I’ll post starting from this code and pushing different things each time. They’ll start slow and simple, like this one. All I’m doing is adding a few lines of code. The first thing I wanted to see from the original was a more gradual step in the width of the line. Here are a few screenshots from this iteration:

Method Explained

If you need a little walk through on my method to achieve this, all I did was create a variable to hold my line width, and the line width velocity (or rate of change). Every frame the line velocity grows or shrinks randomly and is applied to the line width variable. I apply a dampen to the velocity so it doesn’t get too out of hand and then set some limits to the line width. Pretty simple and it applies the same method of applying velocity to an object to make it move, but this velocity is being applied to a property of the object (width) that may not be as obvious as position. This still gives an effect of random width to the lines, but they are randomly widening and thinning, rather than just having random widths. It gives it a more fluid appearance. Any other ways you would use to achieve the same effect?

Interactive Generative Flash Art Series Intro

Posted on January 27, 2011August 29, 2014 by Evan Mullins

The world has been excited by html5/css3 recently and has been pushing limits and experimenting. It’s been exciting and funny at the same time – most of the things that are amazing people in html5 experiments have been done 5 years ago in flash. I’ve enjoyed it so much though because it has brought me back to what made me fall for flash initially: sites like levitated.net and yugop.com. People that wrote books about programming actionscript like Keith Peters, Jim Bumgardener Colin Moock, Robert Penner etc… and then art by people like Erik Natzke. I’m a geek and these guys are some of my heros (and don’t think that list is exhausted, I’ve got plenty of unmentioned flash heros), but not just because they could/can do what they do, but because they selflessly (open source-ly) taught me how to do some of it. The magic of creating something so engaging, responsive, animated, unique, random. Little experiments that feel like they contain so much life and are so lightweight -easily less than 10,240 bytes (read 10kb). I knew in high school trig and calculus that those formulas had power, but seeing it unfold and interact with it really is magical to me.

A little inspiration

So, I’ve been toying with a lot of the things that actually taught me (or at least pushed me to learn) the basics of programming. With the years experience under my belt now I’m understanding it on a totally different level and all I want to do is find more things to make balls and lines bounce, move and swirl. And I also want to share it. Well, I recently stumbled upon a flash sneak peak video by Erik Natzke about some of his technique and then his open source files and really had some fun. Anyways I wanted to share some of the experiments that came from it. Let me know your thoughts and download the code and play with it. Let me know what else you come up with and share what you learn. I’ll start this series with a post of the original experiment from Erik on his blog here, Flash Code 101.

Well, I’ll be playing with this code and others and posting the experiments with some screenshots of what I create get’s created.

Video Player 4 introduces interactive playlists, social sharing and more

Posted on December 22, 2010August 29, 2014 by Evan Mullins

I’ve been busy hardening and improving my video player lately and had so many updates for it I decided to upload it to activeden as a new file altogether. After some final bug fixes and testing it’s been approved for sale. I think it’s a huge improvement over the last video player. The video playing part is mainly the same (with a few small adjustments for better usability), but I’ve added tons to this update. It’s online at activeden for live preview and purchase.

An extensively customizable yet simple video player. Create and manage play lists for you video delivery as well as allow viewers to share and socially bookmark the video. Integrate the video into your user experience with javascript integration as well as Google Analytics tracking on the video interaction! Control functionality, layout and colors of the player easily! Plus don’t sweat the embed codes – an embed code generator included!

Check out the legend graphic for some views of the player and the different panes. There is the full video view, the playlist, share and detail panes. You can also view them all in fullscreen mode.

This new player has the following updates:

Includes an embed script generator built specifically for this video player! Embed script generator with a Live Preview!
Use an external xml playlist or set playlist values in flashvars settings. (No need for xml if you don’t want it)
Social Bookmarking with facebook, twitter, delicious, google buzz & linkedin
Send emails through the player to share the video with friends
Google Analytics Integration (event tracking) – Uses your analytics account on a per video setting in flashvars.
All colors fully customizable in flashvars or xml
Display video title and description – html content (may contain links) in the detail pane.
Video controls also in context menu (right-click menu)
Loop the video once, twice however many times you wish and even infinitely!
Disable tooltips completely if you wish
Keyboard shortcut integration! Press the space bar to pause/play the video just like in most video playback programs.
Volume setting cached across sessions for a better user experience
Double click video for fullscreen

As well as all that made version 3 video player great as well:

Supports flv, f4v and any container format using H.264: mp4, m4a, mov, mp4v, 3GP, 3G2.
All images and video loaded externally

Access the html page URL and swf path from flash with as3

Posted on December 16, 2010August 29, 2014 by Evan Mullins

To get the url of the html page that contains the flash/swf file we need a little help from the browser. I’ve written about the following methods before, but they were in as2 with “Get current url to Flash swf using an External Interface call” and “Get Current URL and Query String Parameters to Flash in as2“. In as3, we’ll still need access to javascript in the form of ExternalInterface, so if you want to do this on a site that doesn’t allow javascript you’ll have to keep searching (or jump to the bottom for an alternative method). We don’t need to do anything with the javascript or have access to the pages source code, javascript just has to be enabled, and it works in every browser I have access to. All we do is call a javascript line from within the swf which gets the url in the browser, namely:
window.location.href
That is the javascript we need to call. But we do it from an externalInterface call like so:
ExternalInterface.call("window.location.href.toString")
or to make sure all browsers play nicely we can wrap it in a function in case the browser doesn’t want to execute that as a line, this seems to work more solidly:
ExternalInterface.call("function(){ return window.location.href.toString();}")
also note that we’re specifically applying the toString method, this is needed so the javascript actually executes something and can return it.

Other things you may want to do related to this is getting the query string variables form the url, which also uses externalInterface. You can also use this same method to get the domain, path, protocol, and even referrer. You could use some nice regex or substrings to find these from the full url, but it is already accessible. I can see a potential need for the speed to get the full url and then use internal code to cut it however I need it. But, I’m not convinced that using an external interface call takes that much time (but it’d be an interesting experiment to say the least).

You may want to find the url to the actual swf, and this doesn’t require javascript at all, the swf does know where it is even if it doesn’t know where it is embedded. We can use the loderInfo object and the url property. This returns the url to the swf file regardless of what page or even domain it is embedded on:
this.loaderInfo.url

For ExternalInterface to work in IE you need valid classid and id attributes in the
