I dont whether i can post this question here or there is any other Forum for ActionScript , if so sorry for that .
Now to the question , I know some what ActionScript like Events , custom UI Components , and classes as required for simple FLEX development .
To what extent we need to learn ActionScript to develop Flash Games ??
Can anybody suggest me as where to start with , what is the correct approach and is there any IDE avialable for that .
Please share your ideas on this
Depends on what sort of games you want to write, firstly you will definitely need to become familiar with actionscript, most gaming and 3d engines for flash games are done in pure actionscript. You can developer your games in flex even if you don't uses mxml basically the real power of games is in the code which means actionscript.
