I'm requiring Flash's well-deployed nature for a large-ish project. ActionScript is just ECMAScript, so I figured it shouldn't be rough transitioning from the web browser environment to the Flash environment, except that all tutorials I can find involve animation, and only barely touch on ActionScript.
My project is a MathML editor and renderer, so I just need to track keyboard events and selections, embed a font, parse some XML, and dynamically create textboxes positioned accordingly. I feel as though those things aren't terribly difficult, but when I can't even find where to write ActionScript when I fire up Flash MX, I think I am in trouble.
I've also looked into HaXe, which can compile to SWF, but its website is down for the moment so that will have to wait.
Any ideas for resources that would be more appropriate than laboriously explaining tweening and explaining var x:Int=5+2; in ActionScript?
