public class RandomTerrain

extends Terrain

Implements a terrain object that chooses randomly from a set of tiles when placed in a map.

Often a map will have large areas of terrain sampled randomly from a small set. For instance, a "grass" area that has three or four different grass tiles appearing randomly for variety.

Map files can be stored much more compactly if the terrain is all the same archetype over a large area, so this class lets maps use the random-terrain distribution compactly. The only difference is that the actual appearance will differ from game session to session, but the overall effect is the same.
