Aim bone/ torso to a direction?

Hi, im making a 3rd person shooter game, and im making my animations in blender. My question is, how do i aim my torso around / keep it aiming at the center of the screen AND being able to aim it around even when other animations are playing ( eg: walking, running, jumping animation cycles ) ? I also found this thread link

but i cant really understand the answer, as I am quite a beginner at scripting. Anyone explain to me in detail how to make this happen? Thanks!

You need HeadLookController script. Download this example: http://unity3d.com/support/resources/unity-extensions/head-look-controller and play around with it and see it helps you.
