Detailed Description

Hitting is temporary Quad that is displayed at the place wall (Box) has been hit by the wall.

Hitti is an object that is animated to blur until disapearance. To make it smooth, mDeltaOpacity is calculcated based on frame rate and changed before it is drawn. In environment in which scene is not drawn based on frame rate this techique would have to be altered to remember time and calcuclate blur delta based on time delta.
