This function is used to determine the parent of an element.

Syntax

element getElementParent ( element theElement )

Required Arguments

  • theElement: The child of the parent element you want returned.

Returns

This returns the parent as an element. It returns false if theElement is invalid, or is the root node.

Example

Consider the following map file: 

<spawngroup id="red">
   <spawnpoint id="spawnpoint_0" posX="2507.8715820313" posY="2772.6071777344" posZ="10.8203125" rot="270" skin="285"/>
   <spawnpoint id="spawnpoint_1" posX="2508.060546875" posY="2780.3647460938" posZ="10.8203125" rot="270" skin="285"/>
</spawngroup>
<spawngroup id="blue">
   <spawnpoint id="spawnpoint_5" posX="2733.4184570313" posY="2753.1276855469" posZ="10.8203125" rot="90" skin="124"/>
   <spawnpoint id="spawnpoint_6" posX="2733.5258789063" posY="2748.1110839844" posZ="10.8203125" rot="90" skin="125"/>
</spawngroup>

This function determines a spawnpoint's parent element, and announces it's ID: 

addEventHandler ( "onSpawnpointUse", getRootElement (), "spawnpointUse" )
function spawnpointUse ( player ) -- this function gets called whenever a spawnpoint is used
   theSpawnGroup = getElementParent ( source ) -- get the spawnpoint's parent element
   -- announce the parent's ID and the player who spawned there:
   outputChatBox ( getClientName ( player ) .. " spawned at team " .. getElementID ( theSpawnGroup ) .. "'s spawnpoint." )
   -- Example output: "Joe spawned at team blue's spawnpoint."
end
