Description

Description:
Return a UniqueID of the given unit (player).
Prior to Arma 2: Operation Arrowhead v1.60, the result always consisted of a stringified number (see getPlayerUIDOld), but always had to be considered and processed as a String. Converting it to a Number could cause precision problems, as Number cannot accurately represent integers above 16777216 (224). Moreover, games since Arma 2: Operation Arrowhead v1.61 provide a value that is not all-numeric.
Arma 3
The returned string is the player's steamID64: private _steamProfileUrl = "http://steamcommunity.com/profiles/" + (getPlayerUID player);
Prior to Arma 3 v2.02, in some cases the identity of certain player units could fail to propagate to other clients and the server, which caused isPlayer and getPlayerUID to incorrectly return false and "" respectively, where the affected units were not local. See this bug report (GitHub) for more info. This was supposedly fixed, but you should remain vigilant toward false negatives nonetheless.

String - Can be "_SP_AI_" or "_SP_PLAYER_" in SP, "" or UID in MP
  • The unique ID may be up to 100 characters long and may contain numbers, uppercase letters and underscores
