code/datums/ai/basic_mobs/targetting_datums/basic_targetting_datum.dm

/datum/targetting_datumDatum for basic mobs to define what they can attack.
/datum/targetting_datum/basic/allow_itemsSubtype more forgiving for items. Careful, this can go wrong and keep a mob hyper-focused on an item it can't lose aggro on
/datum/targetting_datum/basic/ignore_factionSubtype which doesn't care about faction Mobs which retaliate but don't otherwise target seek should just attack anything which annoys them
