This function sets the ID of an element to a string. This can be anything from an identifying number, to a name. You can only change the ID of an element clientside if that element has been created clientside as well.

Syntax

bool setElementID ( element theElement, string name )

OOP Syntax Help! I don't understand this!

Method: element:setID(...)
Variable: .id
Counterpart: getElementID


Required Arguments

  • theElement: The element you want to set the ID of.
  • name: The new ID for theElement.

Returns

This returns true if successful. It will return false if theElement is invalid, or does not exist, or if name is invalid, or is not a string.

Example

local players = getElementsByType( "player" )
 
for i=1,#players do
   setElementID( players[i], "player" .. i )	-- Change element IDs to 'player1', 'players2', 'players3'...
   outputDebugString( "Player[" .. i .. "] = " .. getElementID( players[i] ) ) -- Output all the new element IDs
end


-- Could also be --

for i=1,#players do
   setElementID( players[i], getPlayerName( players[i] ) )	-- Change the element ID to the players name.
   outputDebugString( "Player[" .. i .. "] = " .. getElementID( players[i] ) )
end
