This feature adds the capability to pass an extra parameter
lgento the NLEseed()function for the purposes of having a deterministic dungeon layout, while allowing the in-game play to be randomly guided (e.g. combat etc.)It works by creating a new Random Number Generator using this seed value when the environment
reset()function is called. This RNG is swapped with the NetHackcoreRNG during the level generation (seemaklev.c:1003), where random numbers are sampled from the known RNG. It is then swapped back once the level is created (seemaklev.c:1041), and subsequent random numbers will be sampled fromcore.The RNGs are swapped again each time a new level is generated as the hero descends through the dungeon, ensuring that level generation random number sampling is kept separate from the in-game random number samples.
