This thread on the Google Maps API for Flash Group Forum caught my attention yesterday:

• Pure AS3 setup of Google map via Flash Develop

The author outlines the steps required to get FlashDevelop up and running with the Google Maps API for Flash. FlashDevelop is a free and open source IDE with code completion for ActionScript, MXML, XML, and HTML.

It provides a compelling alternative to FlexBuilder and is worth a look. Please donate to the project if you use it!

I followed the steps outlined in the thread and everything worked as described. Here are a few extra details that might be useful:

• The FlashDevelop home page is www.flashdevelop.org
• I had to download and install the Java Runtime Environment before installing FlashDevelop.
• When installing the Flex SDK, place it in C:\Program Files\FlashDevelop\Tools\flexsdk for automatic configuration
• If you don’t already have the Flash Debug Player, download and install the latest version from Adobe

Hope this helps!
