I want to start Flash/Flex/ActionScript development and got lost with the technologies, documentation and tools available. Searches pointed me to Adobe FlexBuilder and Adobe Flash (Designer, CS3, CS4).
Then, I found FlashDevelop, learned that Flex SDK and compilers are free. Also, you can make a complete Flash application in FlashDevelop (using "FLA dummy" method).
Question - what traning materials I should start from to understand how to develop Flash applications using FlashDevelop?
I look for training materials, guides, tutorials, screencast, books (amazon kindle) for beginners in Flash using free tools (either FlashDevelop or TextEditor + compiler), but not for beginners in programming (know few languages already).
A lot of help can be found on their wiki - FlashDevelop wiki
If you want to start developing in Flex (which might be a really nice idea if you're coming from desktop development) FlashDevelop will work, but I would suggest to use Flex Builder first, as a lot of examples you will find on the web are built using that, and it's really very straight forward, as it's aimed ad Flex. If you're a student you can get a free license from Adobe here, if you're not than there is a 30 day free trial.
