 For example: The `FlightTime` of a hedgehog (`gtHedgehog`) is the time since they last have stood on solid ground. For most projectile gear types (i.e. `gtShell`), it stores the time after it has been launched.
 
 === <tt>!GetGearElasticity(gearUid) </tt> ===
-Returns the elasticity of the specified gear. Useful for determining if a hog is on a rope or not. If a hog is attached to a rope, or is busy firing one, the elasticity of the rope will be non-zero.
+Returns the elasticity of the specified gear. The elasticity normally determines how strong the gear will bounce after collisions, where higher elasticity is for stronger bounces.

+Returns the friction of the specified gear. The friction normally determines how well the gear will slide on terrain. Higher values are for increased sliding properties.

 Sets the `FlightTime` of the given gear to `flighttime`. The meaning of `FlightTime` is explained in the section `GetFlightTime`.

+Sets the elasticity of the specified gear. For most gears, the elasticity determines how strong the gear will bounce after collisions, where higher elasticity is for stronger bounces. Recommended are values between `0` and `9999`.

 === <tt>!SetAmmo(ammoType, count, probability, delay, numberInCrate)</tt> ===
 This updates the settings for a specified [AmmoTypes Ammo Type] as of count available for players, spawn probability, availability delay in turns, and the number available in crates. This is supposed to be used in the `onAmmoStoreInit()` event handler.
