[[{{{image}}}|link=|]] Important Note: If you wish to retrieve more than one element at a time, it is more efficient to use getElementsByType instead.

This function returns an element of the specified type with the specified index.

Syntax

element getElementByIndex ( string theType, int index )

OOP Syntax Help! I don't understand this!

Note: This function is a static function inside the Element class.
Method: Element.getByIndex(...)


Required Arguments

  • theType: the type of the element to be returned. Examples include "player", "vehicle", or a custom type.
  • index: the element's index (0 for the first element, 1 for the second, etc).

Returns

Returns the requested element, or false if it doesn't exist.

Example

This example generates the name of the specified player that is on the server. For example: 'player 0' would return the name of the first player on the server. 

function showPlayer(command, index)
	local thePlayer = getElementByIndex("player", tonumber(index))
	if thePlayer then
		outputChatBox("Player " .. index .. " is a: " .. getPlayerName(thePlayer))
	else
		outputChatBox("Player not found.")
	end
end
addCommandHandler("player", showPlayer)
