Arx Fatalis casting system

Unity Engine

I was playing the old classic Arx Fatalis recently and it got me thinking how they implemented the whole “draw the rune symbol” to cast a spell. I’m just curious how you would do this in Unity because it would be a really cool feature for an RPG game (not that I’m making one just curious). I really have no ideas myself…

Here’s a video for those that have never played this game:

It’s a gesture based system. There’s an example here: http://www.unifycommunity.com/wiki/index.php?title=Gesture_Recognizer
