This function returns an element based on it's parent.



Syntax

element getElementChild ( element parent, int index )

Required Arguments

  • parent: the element above the one to be returned in the hierarchy.
  • index: the element's index (0 for the first element, 1 for the second, etc).

Returns

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

Example

To spawn a player at the red team's third spawnpoint: 

<team1 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"/>
    <spawnpoint id="spawnpoint_2" posX="2508.0053710938" posY="2776.2897949219" posZ="10.8203125" rot="270" skin="285"/>
    <spawnpoint id="spawnpoint_3" posX="2510.6899414063" posY="2778.3745117188" posZ="10.8203125" rot="270" skin="285"/>
</team1>

You could use the following code: 

teamRed = getElementByID ( "red" ) -- find the parent element by it's ID and assign it to teamRed variable
teamRedSpawn = getElementChild ( teamRed, 2 ) -- find teamRed's third child element (which happens to be a spawnpoint)
spawnPlayer ( somePlayer, teamRedSpawn ) -- spawn a player at the spawnpoint
