what do the keyvalues do and how do I make the NPCs patrtol?

I wonder the same thing tbh

I think KeyValues are things like setting if an Antlion guard will spawn as an Antlion Guardian from Half-Life 2: EPISODE 2. Example: {cavernbreed = 1, incavern = 1}: That makes it so the antlion guard will deal Toxic damage and have the Green Glow. though it won't look LIKE the guardian.

EDIT: Discovered More Keyvalues, { citizentype = CT_REFUGEE or CT_DOWNTRODDEN or CT_REBEL or CT_UNIQUE
