This function has collisions, where more than one player has the same UniqueID. It is highly recommended to use Player:AccountID, Player:SteamID or Player:SteamID64 instead, which are guaranteed to be unique to each player.
Returns a 32 bit integer that remains constant for a player across joins/leaves and across different servers. This can be used when a string is inappropriate - e.g. in a database primary key.
In Singleplayer, this function will always return 1.
Gets the Unique ID of a player.
Entity( 1 ):UniqueID()
Functional equivalent of this function.
local ply = Entity( 1 ) local uniqueid = util.CRC( "gm_" .. ply:SteamID() .. "_gm" ) print( uniqueid )
