User:Furey/NetHack Combat Internals (3.6.7)

This article is for NetHack 3.6.7.

Several articles such as Double damage, Damage type, and Attack type will benefit from this.

Damage type

Start with mattacku. This dispatches on attack type to about ten different damage functions. Each damage function switches on the damage types that it cares about. A few damage types are in multiple functions notably AD_STON, and they have different effects for different attack types.

For passive damage (AT_NONE), start with uhitm which calls passive. passive has its own codepath for cancellation and magic cancellation. Again AD_STON has significantly different behavior for AT_NONE vs other attack types.

Monster on monster combat arrives at mhitm among other functions. Completely different code path from mhitu. Lots of major differences and innumerable minor differences.
