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!
