With all the buzz about new improvements in CSS3 I’ve been meaning to write about it, but…
I couldn’t find any excuses when I stumbled on Paul Irish’s new css3please.com: a cross-browser css3 rule generator. Just had to do a quick post to spread the word.
It’s great for cross-browser testing as well as generating the code for many css3 rules:
and more coming soon!
Flashvars and actionscript 3! Flashvar is a way that in your html embed codes (object tags) you can send variables and values into your swf file. These variables can then be grabbed internally and used your programming! Examples of these could be images that you want to use in your swf but don’t want to import or hardcode them into the flash file or paths to xml or flv files to use as well. Actionscript 3 has a different procedure than as2 did as to how you read these flashvars from the actionscript side. The embed codes and html side of things are still the same, but in case your new to actionscript altogether, I’ll give an example of the html as well.
1 2 3 | <object width="200" height="200" type="application/x-shockwave-flash" data="flashvars_as3.swf"> <param name="flashvars" value="colors=0x012345,0x123456,0x234567,0x345678,0x456789,0x567890,0x678901,0x789012&delay=.11&loop=true&random=false"/> </object> |
In actionscript 3 we use the loaderInfo object to access the flashvars. The parameters Object of the loaderInfo will contain all the flashvar variables and values.
1 | this.loaderInfo.parameters |
As an example of something that is visual I’ve created this little app to read some options from flashvars about colors. An app that will read a list of colors and update a box that is on the stage already to those colors with the specified delay. I always have fun with randomness so I threw in the option for random colors as well. This file looks for certain flashvars: color, loop, delay and random. These are the keys or names of the variables and they are followed by the values you want them to hold. Note that flashvars can be set in any order, so you don’t have to start with color and end with random.
In this example I’m looking for 4 flashvars specifically (in any order):
This is much more than is required for this example, but I was having fun playing with random colors and timing and options. I figured it diesn’t hurt to show the effect you can have with a couple different variables on one file. Here is an example using the object tags above:
And here are some more (please don’t have a seizure!)

Interactive Design project for StomperNet’s tease of the announced reveal on 09/09/09 at 09:09:09!
Wanted it to be unexpected, and I think we hit it! Check it out live at stomper999.com!
Details:
For this project I used flash, html, css and javascript. Tweener for the fading effects. Found a nice stock flash from flashDen for the countdown and used jquery and the easing and color plugins.
Here is a preview of a file I’m writing a tutorial for. It’s nothing groundbreaking, but it deals with many normal tasks and will show my process a bit. This tutorial will show how to create a horizontally scrolling image viewer. It will cover xml loading & parsing, loading & resizing external images to fit into a scrollable container, and creating intuitive and responsive scrolling!
Let me know what you think, and if there’s anything you want specifically mentioned/explained in it I’ll do my best! Or if you have any ideas of how this could be improved.
Update: The article/tutorial has now been published follow the link to theTutorial to Create a Responsive Image Scroller in ActionScript 3.0
StomperNet relaunched the popular FormaulFIVE and I was responsible for the design of the landing pages. Here are screenshots from the launch, FormulaFIVE was teased with a couple video trailers and even packaged with some bonus videos called the Cash Booster series.
