Customizable camera movement based on MouseXY movement (desktop only)

Hi
Fairly common request I'm sure but I need a customizable camera movement script for a desktop application. I need to be able to control both

1) the amount of camera movement relative to mouse xy movement
and
2) the amount of camera movement inertia

Is anyone aware of a C# based script that accomplishes the above?

 

I believe the fps character controller in the standard assets has all the code you need for that.

 

Thanks. Yes there is the MouseLook script but it lacks inertia
