Map

From The Cataclysm: Dark Days Ahead Wiki
Jump to: navigation, search

Overmap is the world map, what you see when you hit the m key, it is essentially endless and can be limited only by external means. Character can see five tiles on the overmap in any direction, binoculars double that distance, but some structures still obstruct range of view.

Each overmap tile (e.g. house, crossroad, forest) equates to a single tinymap, or 24x24 player-size tiles. Tinymap is not really used in the code much, but it is available because it is more efficient than a map.

Map is 156x156 player-size tiles and used in normal gameplay; the game has a map m, which is the area which is considered "in-play," inside which monsters, fields, traps, etc. will be processed. Other than their respective sizes, map and tinymap are completely identical.

Both tinymap and map are formed of an array of submaps. A submap is 12x12 player-sized tiles, and also keeps track of any fields, items, traps, and computers in that area. Tinymap is made up of 2x2 submaps; map is made up of 13x13 submaps.

Overmap legend

Wilderness

Wilderness tiles need some distance from a town to spawn. So if certain locations, like the LMOE shelter, or labs don't show up, the world settings have to large cities and to little space between them.

Map tiles usually found outside towns.

C cathedral 5

A large stone structure with numerous stained glass windows. Before the dark days, Cathedrals were a place of worship and community. You will find them in a town or city. There are numerous entrances and exits.

Cathedrals have an above ground worship area that consists of an entry way, a large room with numerous wooden pews. The pews are separated from the altar by metal railings. On the altar you will usually find some braziers. However, you may find that the worship that occurred here may not have been entirely benevolent.

The cathedral basement is a meeting area with two sets of restrooms, two classrooms, and a kitchen. Before the days became truly dark, Cathedrals were used as shelters and you will find a number of beds, and a well-appointed kitchen and dining areas. There is probably a broken console.

The structure take up 4 tiles. If you can clear it and keep it defended, it might make a good home base.

C cathedral basement 5

In the basement of a Cathedral you will find a meeting area with two sets of restrooms, two classrooms, and a kitchen. Before the days became truly dark, Cathedrals were used as shelters and you will find a number of beds, and a well-appointed kitchen and dining areas. There is probably a broken console.

Behind a storage area on the North edge of the basement is a locked wooden door leading to a dank, dark, secret worship altar. There are two lifeless bodies wandering about here that are clearly tortured souls. These bodies will not hurt you, and you need not kill them. On the secret altar is a small relic that might be useful in some NPC quests.

There are four entrances, two from the inside of the cathedral, and two from outside.
