This function sets the position of an element to the specified coordinates.

Syntax

bool setElementPosition ( element theElement, float x, float y, float z )

Required Arguments

  • theElement: A valid element to be moved.
  • x: The x coordinate of the destination.
  • y: The y coordinate of the destination.
  • z: The z coordinate of the destination.

Returns

Returns true if the function was successful, false otherwise.

Example

Example 1

This example adds a "setpos" command to console, which allows setting of a player's position. 

function consoleSetPlayerPosition ( source, commandName, posX, posY, posZ )
	setElementPosition ( source, posX, posY, posZ )
end
addCommandHandler ( "setpos", consoleSetPlayerPosition  )

<section name="Example 2" class="client" show="false"> This example adds a "setpos" command to console, which allows setting of the local player's position. 

function consoleSetPlayerPosition ( commandName, posX, posY, posZ )
	setElementPosition ( getLocalPlayer(), posX, posY, posZ )
