If you want to, my suggestion is to follow Davio's advice. The tutorials will teach you everything you need to know and offer great introductions to all of Construct's features. A good place to start would actually be Deadeye's Platform School Tutorial:viewtopic.php?f=8&t=8913
He gives a great overview on setting up conditional animations. Yea, the tutorials are for 2D sidescrolling platformers, but the principles really are the same as far as animations in Construct go. You'll want to get used to the event sheet system and variables and such, as they are what give you control over what animations are being displayed at any given time on whatever sprites are picked.
I really really recommend listening to Davio if you want to get anywhere with Construct. Go through the tutorials and become intimate with the program. They explain far better and through examples. I can tell you from experience as I myself am working on a top down action RPG and would not have gotten anywhere with it if I hadn't gone through the tutorials.
