Over the years I've gotten a lot of questions based on flash, like where to get the program, how to animate sprites, how to import items, and even some who desperately ask me to teach them flash. But to be honest I'm not very good at explaining this stuff. Just because I know flash doesn't mean I can teach you guys. I just don't have the time (nor the patience) for that lately. It's not easy for me to explain it through email or messenger.

That's why I recommend visiting the Flash Tutorials Page.
It explains almost everything you need to now like:
-where to get a free trial version of flash.
-An introduction of how flash works
-animation tutorials.
-sprite Tutorials
-Game Tutorials
-Button Tutorials
and much more.

I learned a lot from some of these tutorials and and the rest was pretty much Trial and error for me.
You need to play around with the program to fully understand how it works. I know it may sound frustrating, but flash isn't easy to use the first time around.Believe me.
