This is a little project prototype I whipped up using the new Skeleton API for LEAP. The new API is a huge improvement with lots of examples.
The first thing I did was hook up some mechanim animations so I could smash bad guys. (Of course the bad guys will eventually have rat tails and actually be animals). I'm using Mixamo animated content with mechanim for the state machine. I did use some scripting to control switching between states to for explict control of the states.
Monsters begin with a smoke cloud where they are instantiated in a laying down position which switches to a sitting upright to standing animation. Once standing they begin walking with a walking animation towards the camera. If they get near the camera the screen shakes. Otherwise the bad guys have a trigger when hit randomly plays 5 different falling to death animations. At which point an explosion or blood splatter particle effect plays. The monster lays down dead and eventually disappears.
I found some useful particle effects for explosion, smoke, and blood in the Unity Asset Store.
And here's a little Prototype: "Rat Smash".
And then I saw the recent newsletter where I'll need to add picking up and throwing too.
