2 // C++ Interface: TerrainModObserver
3 //
4 // Description: The purpose of this class is to handle the bulk of the work
5 // involved with using Mercator::TerrainMods. It handles parsing
6 // the Atlas data and storing all the information needed by
7 // TerrainGenerator to add and remove them from the Terrain.
8 //
9 // TerrainGenerator listens for changes in the modifier and
10 // updates or removes the modifiers from the terrain as needed.
