Random vaults (not to be confused with [[Vault]]s) are a part of the level generation formula introduced in [[UnNetHack]].  
+
'''Random vaults''' are a part of the level generation formula used in [[UnNetHack]]. Despite the name, these are entirely unrelated to the hidden [[vault]]s filled with gold, and are used to create unique rooms that connect normally to the rest of the dungeon.
  
−
Despite the name, "random vaults" connect to the rest of the dungeon normally.  
+
In the UnNetHack source code, the random vaults are defined in <code>dat/vaults.des</code>. The upcoming release of [[NetHack 3.7.0]] will have a similar feature, called [[themed room]]s.
−
{{todo|This is still confusing - as evidenced by the [[Talk:Random vault (UnNetHack)|talk page]]...}}
 
  
−
All rooms in the main branch of the dungeon that are not gold vaults or part of special levels are selected from the list of random vaults.
+
==Description==
 +
Every room that is not a vault or part of a special level and not a vault is selected from the list of random vaults. The "normal random room" has a {{frac|40|41}} chance of being selected; all the others have a {{frac|2050}} chance of being selected. Some of these rooms can be further transformed into [[special room]]s.
  
−
When selecting what random vault to place, each random vault has about a 1/2000 chance of being selected. If none are chosen, the vault selected is "Normal Random Room" - which is simply a normal room as you would often find in vanilla. In addition, some of these vaults (including "Normal Random Room") can be further transformed into [[Special room]]s. When this is possible, it is stated in the description of the individual vault, and follows the normal probabilities for generating special rooms.

Latest revision as of 02:07, 17 February 2024

Random vaults are a part of the level generation formula used in UnNetHack. Despite the name, these are entirely unrelated to the hidden vaults filled with gold, and are used to create unique rooms that connect normally to the rest of the dungeon.

In the UnNetHack source code, the random vaults are defined in dat/vaults.des. The upcoming release of NetHack 3.7.0 will have a similar feature, called themed rooms.

Description

Every room that is not a vault or part of a special level and not a vault is selected from the list of random vaults. The "normal random room" has a 40⁄41 chance of being selected; all the others have a 1⁄2050 chance of being selected. Some of these rooms can be further transformed into special rooms.

Possible vaults

Name Can be special Size Map Notes
Normal random room Yes
  • The regular rooms found in vanilla NetHack
  • The only one with a unique chance of being generated, (40/41 compared to 1/2050)
Fake Delphi Subroom only 11x9
  • A big room with a small room in the center, similar to Delphi
  • Both the room and the subroom are guaranteed to be lit
  • There is a door to the subroom, with a 25% chance of a second door.
  • Both doors have a chance of being locked and/or trapped and/or secret.
room with a subroom Subroom only
  • A random room with a random subroom
big room, 1 No 30x10
  • Has a 75% chance of having a random normal room as a subroom
    • This subroom will have a randomly placed door with a 50% chance of a second door
    • Both doors have a chance of being locked and/or trapped and/or secret.
lava/ice/pool/tree/fountain room No 3x3
  • The center square of the room has an equal chance of being lava, ice, pool, tree, or fountain.
  • Each other square has a 10% chance of being the same as the center square.
big room, 2 (max. vertical height) No 10x17
  • 2d3 random hostile monsters
thin, long, horizontal room No 17x3
  • 2d3 random hostile monsters

  • Otherwise: subroom also has a random M, D, O, Z, T, or H and the monster will now be caged in iron bars
room with dangerous monster and loot No
  • Up to 3 monsters from the classes M, D, O, Z, T, or H
    • 100% chance of the first random hostile monster
    • 50% chance of a second hostile monster
    • 25% chance of a third monster (not guaranteed to be hostile)
    • These percentages are calculated independently, so there is still a 25% chance, even if the 50% chance fails.
  • Random object
    • 100% chance of the first object
    • 75% chance of a second object
    • 50% chance of a third object
    • 25% chance of a fourth object (this one will be cursed)
