Something I worked on a couple of months ago, a prototype of a simple collision-based melee system just using basic shapes & Unity's mechanim system
Being collision-based makes some aspects of this easier - for example, less fiddling with events during animation, just using 2 events to turn collision on and off, and re-usable code for parries when using a block-animation or simply swinging into the enemies sword during their attack. It does introduce some interesting problems, though I rather like the effect of it
Also includes slow-motion, and tasteful dynamic arterial blood spray! What more could you ask for!
