I’m so excited for my first real experiment with Arduino and Actionscript 3.0 using external hardware to communicate and control my Flash applications, and viceversa.

Request: How to set a global component style in Flash / AS3?
Solution: Use StyleManager class and setComponentStyle method to set global styles

Reading RSS feeds from Flex or Flash often generate some security issues when the origin domain doesn’t contain a crossdomain.xml file to manage the policy settings.
A little workaround is create a PHP proxy to read the feeds and pass the content to the Flex script.

As often happens, i got the expiration to write this little post after an user request from an actionscript.it forum.
In few words, user asked how integrate a Google Search inside its Flex application to display the result always inside the flash app.
So I started to surf around the web to find a valid solution, and after founding many PHP solutions I found a cool AS3 library, developed by Boulevart.
This API provides a lot of classes to connect Flex (and Flash too) to Google services (Google Search, Translation, News, and so …

In this post I’ll show you how to create a form with a file attachment using Flash CS3/4, ActionScript 3.0 and PHP. The trick is use the FileReference class to upload a file from your own hard disk and at the same time send the input- field values.

I’m really happy to see that in Flash Builder 4, the next release of Flex out in spring 2010, a complete video player component will be finally available with a lot of integrated features: play/pause, progress bar, time and fullScreen button too.

See it in action (click on buttons to play videos)

In this sample, full-commented, we’ll use the FlashPlayer 10 3D features to display a list of Video Thumbnails enabling the Mouse Click Event to enlarge them changing their z and rotationY properties.
We’ll use Caurina Tween to perform 3d animations, so download them and copy the caurina package in your project folder before test this sample (they are not included inside the source files)

In this post I’ll provide you just a quick way to change a TextField font family at runtime using ActionScript 3.0 and Flash Cs3/4 getting your embedded fonts from the Library .

When Actionscript 3.0 was a dream and all Flash developers worked with AS2 the _global property was a smart and fast way to share variables between swf files.
A classic scenario is the following:
1) In the main swf file there is the language selection and users can make their choice selecting the site language
2) This swf probably will have a menu to load different pages, each one with their content and galleries to load.
3) Every loaded page will need to know the selected language value to load the right content (for example …

Two of the most popular questions when loading SWF files in Flash CSx / AS3 are:

how to call a method in the loaded swf from the Main document class
how to reference at the main document class to call a method from the the loaded swf.

In this post I’ll provide you a quick and easy sample to cover both situations.
This is not the best way to accomplish this task but it’s very easy to understand and use.

So what we’ll do?
1) We’ll load the file Page.swf inside Main.swf clicking on …
