unit uGears;
(*
 * This unit defines the behavior of gears.
 *
 * Gears are "things"/"objects" that may be visible to the player or not,
 * but always have an effect on the course of the game.
 *
 * E.g.: weapons, hedgehogs, etc.
 *
 * Note: The visual appearance of gears is defined in the unit "uGearsRender".
 *
 * Note: Gears that do not have an effect on the game but are just visual
 *       effects are called "Visual Gears" and defined in the respective unit!
