Forum:Level dimentions?

I am considering making a new level for NetHack to supplement Vlad's tower. Does anyone know the dimentions of a level or if there is an interface for planning out a new level online?

Thanks!

The maximum size of a NetHack level is 79 by 21. Most levels that the game actually uses (e.g. Gehennom mazes) are 77 by 19; I'm not sure if there's some reason for this or if it's simply a case of miscounting.
Look at the .des files in the dat/ folder for level definitions. You can use tools called "lev_comp" and "dgn_comp" (which ship with the game) to replace and/or add new level definitions in the game's data. Also look in the doc/ directory for some instructions on how they work. Ais523 (talk) 04:19, 6 April 2015 (UTC)
