 *     - Making Navi fly over to certain actors of interest (can be lock-on actors, but may also not be)
 *     - Displaying an arrow over an actor that can be locked onto
 *     - Displaying a reticle over the current lock-on actor
 *     - Playing enemy background music if a hostile actor is nearby
 *
 * This system does not handle the actual lock-on implementation.
