Questions about entity exclusion bitflags on mapload

[Dr. Shadowborg]

Okay, starting out what I'm doing now is working on adding deathmatch support to my SP map, and I want to add a deathmatch only flag to stuff like trigger_teleport, func_wall, etc.

Are the "not on skill x / Deathmatch" bitflag exclusions hardcoded into the engine?

Also, does nightmare break this? i.e. If I set a trigger entity / func_wall to not be on easy, normal and hard, will it appear on nightmare?

Yes the exclusions are handled engine side. ('Hardcoded' is such a funny word in a open source engine). Nightmare uses the "hard" bitflag for spawn exclusion.
