This function returns an element from the specified ID. If more than one element with the same ID exists, only the first one in the order it appears in the XML tree will be returned by this function.

[[{{{image}}}|link=|]] Note: The ID in this context is the value of the 'id' data item of the element (the id=".." attribute in the .map file), NOT the model ID, weapon ID or similiar.

Syntax

element getElementByID ( string id, [ int index = 0 ] )  

Required Arguments

  • id: The ID of the element as it appears in the XML file.

Returns

Returns the element with the given ID, or false if no such element exists.

Example

Assuming we have this in the .map file:

<vehicle id="vipVehicle" posX="10" posY="10" posZ="4" model="602" />

Then this example would retrieve the element and output the vehicle name.

function showVipVehicle()
	local vipVehicle = getElementByID("vipVehicle")
	outputChatBox("Vip Vehicle is a: "..getVehicleName(vipVehicle))
end
addCommandHandler("vipVehicle",showVipVehicle)
