SF

Description

Enumerations describing certain spawnflags. Everything except for SF_PHYS* and SF_WEAPON* is serverside only.

Spawnflags are set using Entity:SetKeyValue with "spawnflags" as the key.

SF_CITIZEN_* spawnflags represent spawnflags only usable on npc_citizen.
SF_NPC_* - Usable on all NPCs
SF_PHYSBOX_* - Usable on func_physbox
SF_PHYSPROP_* - Usable on prop_physics entities
SF_WEAPON_* - Usable on Weapons

This is not a full list of available spawnflags, there are a lot more, each unique to each entity, you can find out more on the Valve Developer Community website for the entities in question.
