Space

A space is any location on a NetHack level. Spaces can be occupied by walls, doors, or other dungeon features, a monster, and items. There can be only one monster on a space at one time, including the player, but there can be many items on a space, even if a monster, player or dungeon feature is also there.

Spaces have various terrain types, such as:


 * Solid rock
 * Wall
 * Floor
 * Corridor
 * Cloud
 * Ice
 * Water
 * Lava
 * Air
