Unique Datum Identifiers 
A replacement for plain \refs. Ensures the reference still points to the exact same datum/client, but doesn't prevent GC like tags do. An unintended side effect of how UIDs are formatted: locate() ignores the number and attempts to locate the reference. This is considered a feature — backwards compatibility. Before: var/my_ref = "\ref[my_datum]" var/datum/thing = locate(my_ref) After: var/my_UID = my_datum.UID() var/datum/thing = locateUID(my_UID) | |
| /proc/UID_of | Input is not a typed variable, which allows you to use it anywhere, especially if you don't want to track datum/non-datum typing. |
|---|---|
| /proc/locateUID | Locates a datum based off of the UID |
| /proc/is_type_in_UID_list | If the list UID_list contains a datum UID who's type matches thing's type, returns the UID of that datum in the list. Otherwise returns null. |
| /datum/admin_verb/uid_log | Opens a lof of UIDs |
