why not script a own function is_pc(), is_npc or is_mobile()?
if there are changes (e.g. npcs get a ip / acct-prop :p . don't know why) you could easy modify that.
No need for a new constant, in my opinion.
Edit:
oops
Code:
// POLCLASS_* constants - use with obj.isa(POLCLASS_*)
const POLCLASS_UOBJECT := 1;
const POLCLASS_ITEM := 2;
const POLCLASS_MOBILE := 3;
const POLCLASS_NPC := 4;
const POLCLASS_LOCKABLE := 5;
const POLCLASS_CONTAINER := 6;
const POLCLASS_CORPSE := 7;
const POLCLASS_DOOR := 8;
const POLCLASS_SPELLBOOK := 9;
const POLCLASS_MAP := 10;
const POLCLASS_MULTI := 11;
const POLCLASS_BOAT := 12;
const POLCLASS_HOUSE := 13;
const POLCLASS_EQUIPMENT := 14;
const POLCLASS_ARMOR := 15;
const POLCLASS_WEAPON := 16;
already exists in uo.em. how unnecessary
