A.I Movement

As the subject says, how can i enable good AI??

I’m making a kind of double dragon fighting game in flash mx.

And i would need hints or tips for how to create good enemys, that attack and such…

Right now my enemys atttack, though it’s bloody hard to beat them, so I need some help on creating smart random solutions for my enemys attack movements… (hit radius… when to attack and such)

So if somebody has an idé it would probably help!

Thanx in advance!
