Realistic motion, smooth physics, critical hit and a hitmarker!

I want minecraft to have smoother physics like ''Totally Accurat Batle Simulator'' or TABS for short, this will make it possible to miss by a hair or something.

Realistic run, walk, jump, climb and swing motion will work very well with smooth physics.

Hitting a monster or player's head, or getting hit on the head or other weak point will deal extra damage and would work splendidly with smooth physics and realistic motions as well as a hit marker that tells you when you hit an entity of some.

I REALLY would love to have your support for this rather specific suggestion and thank you so much to those who hava already voted for it.

PS: If this gets in the game I hope you guys love it as much as I would!
