<function name="UniqueID" parent="Player" type="classfunc"> <description> <deprecated><br/> **This function has collisions,** where more than one player can have the same UniqueID. It is **highly** recommended to use <page>Player:SteamID64</page> or <page>Player:SteamID</page> instead, which are guaranteed to be unique to each player.</deprecated> 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. <note>In Singleplayer, this function will always return 1.</note> </description> <realm>Shared</realm> <rets> <ret name="" type="number">The player's Unique ID</ret> </rets> </function> <example> <description>Gets the Unique ID of a player.</description> <code>Entity( 1 ):UniqueID()</code> <output>Something like 1592073762</output> ⤶ </example>⤶ ⤶ ⤶ <example>⤶ <description>Functional equivalent of this function.</description>⤶ <code>⤶ local ply = Entity( 1 )⤶ local uniqueid = util.CRC( "gm_" .. ply:SteamID() ..
