Hook

Overview

On each update hook detects the distance between all select-able objects and the controller. It keeps an ordered list of the select-able objects ranked by a scoring system. Based on this the closest objects will gain score while everything else will lose points. By doing this a user can follow a moving object with the controller and differentiate the object that they want to select by its velocity/movement. How this score is calculated is listed below in the method documentation.
