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

[[|link=|]] Warning: Do not use this function to spawn a player. It will cause problems with other functions like warpPedIntoVehicle. Use spawnPlayer instead.

Syntax

bool setElementPosition ( element theElement, float x, float y, float z [, bool warp = true ] )

OOP Syntax Help! I don't understand this!

Method: element:setPosition(...)
Variable: .position
Counterpart: getElementPosition


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.

Optional Arguments

  • warp: teleports players, resetting any animations they were doing. Setting this to false preserves the current animation.

Returns

Returns true if the function was successful, false otherwise.

Example

Server

This example lets admins teleport 5 random players to themselves 

function randomPlayersToLocation(p)
    if not isPlayerStaff(p) then return end

	local playersOnline = getElementsByType("player")
	local amount = #playersOnline

	if amount == 0 then return end

	for index = 1,(amount > 5 and 5 or amount) do
		local player = playersOnline[index]
		setElementPosition(player, getElementPosition(p))
	end
end
addCommandHandler("randomtp", randomPlayersToLocation)
addCommandHandler("playershere", randomPlayersToLocation)

-- Utility function
local staffACLs = {
    aclGetGroup("Admin"),
    aclGetGroup("Moderator")
}

function isPlayerStaff(p)
	if isElement(p) and getElementType(p) == "player" and not isGuestAccount(getPlayerAccount(p)) then
		local object = getAccountName(getPlayerAccount(p))

		for _, group in ipairs(staffACLs) do
			if isObjectInACLGroup("user." .. object, group) then
				return true
			end
		end
	end
	return false
end

If you want to put a vehicle or player out of the water or simulate the position-resetting behaviour if CJ goes below the ground too far, then you need to retrieve a recommended coordinate on ground to place the element at. Take a look at this MTA forums post for steps in the right direction.
