I wanted to create a flash game, but As a programmer I was very unfamiliar with Action Script 3. The following websites provided and still give great coverage for examples, to explanations of how things work, as well as development resources:
Michael’s Dev Blog – Great for beginners.
AS Gamer – Good Step by Step Walkthroughs.
Dezinerfolio – Great Resource Website.
Flash Game University – Provides Video Walkthroughs.
Flash and Math – Very inspiring work.
Mr Sun Studios – Unique AS3 Examples.
