-This creates a new gear at position x,y (measured from top left) of kind `gearType` (see [GearTypes Gear Types]). The initial velocities are `dx` and `dy`. All arguments are numbers. The function returns the `uid` of the gear created. Gears can have multple states at once: `state` is a bitmask, the flag variables can be found in [States].
+This creates a new gear at position x,y (measured from top left) of kind `gearType` (see [GearTypes Gear Types]).  Gears are dynamic objects or events in the world that affect the gameplay, including hedgehogs, projectiles, weapons, land objects, active utilities and a few more esoteric things.

-This attempts to create a new visual gear at position x,y (measured from top left) of kind `visualGearType` (see [VisualGearTypes Visual Gear Types]).  Visual gears are decorational objects which are usually used for purely decorational graphical effects.  They have no effect on gameplay.

Visual gears are decorational objects which are usually used for purely decorational graphical effects.  They have no effect on gameplay.  Visual gears are not the same as gears, but they share some similarities.
 
 The function returns the `uid` of the visual gear created or `nil` if creation failed.  There is no guarantee that a visual gear will spawn.  *IMPORTANT: Do not rely on visual gears to spawn*. *Always* be prepared for this function to return `nil`.
