SetElementPosition: Difference between revisions

Revision as of 23:39, 5 January 2017

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

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  )

Example 2

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

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

Example 3

This example enables a player to type /warpto <playername> to warp to them. If the player being warped to is in a vehicle with a free passenger seat, it will warp into the vehicle.

function consoleWarpTo ( sourcePlayer, commandName, player2nick )
	-- Make sure required parameters are set
	if ( not sourcePlayer or not player2nick ) then return end
	-- Setup the variables we will be using for teleportation
	local x, y, z, r, d = 0, 0, 0, 0, 2.5
	-- Grab the element identifier of the player we are trying to warp to
	local player2 = getPlayerFromNick ( player2nick )
	-- Make sure it exists!
	if ( player2 ) then
		-- Is the player we're warping to in a vehicle?
		if ( isPlayerInVehicle ( player2 ) ) then
			-- Indeed they are, let's get the vehicle information such as the vehicle element itself, and the seats it's got.
			local player2vehicle = getPlayerOccupiedVehicle ( player2 )
			local numseats = getVehicleMaxPassengers ( player2vehicle )
			local i = 0
			-- Loop over the seats to see if there's a free one
			while ( i < numseats ) do
				if ( getVehicleOccupant ( player2vehicle, i ) ) then
					-- This seat isn't free, go ahead and check the next one
					i = i + 1
				else
					-- This seat is free, get out of the loop
					break
				end
			end
			-- Check if 'i' is lower than the number of seats. If it is, it means it's the number of a free seat
			if ( i < numseats ) then
				-- Teleport the player into the seat
				warpPlayerIntoVehicle ( sourcePlayer, player2vehicle, i )
			else
				-- There are no free seats, tell the player that.
				outputChatBox ( "Sorry, the player's vehicle is full (" .. getVehicleName ( player2vehicle ) .. " " .. i .. "/" .. numseats .. ")", sourcePlayer )
			end
		else
			-- The player isn't in a vehicle, let's get the player's position and warp to them.
			x, y, z = getElementPosition ( player2 )
			r = getPlayerRotation ( player2 )
			-- Make sure we get interior data, they might be inside one!
			interior = getElementInterior ( player2 )
			dimension = getElementDimension ( player2 )
			-- Do some funky math to make sure that we dont teleport inside of them (get us both stuck inside each other)
			x = x - ( ( math.cos ( math.rad ( r + 90 ) ) ) * d )
			y = y - ( ( math.sin ( math.rad ( r + 90 ) ) ) * d )
			-- Set a few timers for setting interiors, dimensions and positions
			setTimer ( setElementInterior, 800, 1, sourcePlayer, interior )
			setTimer ( setElementDimension, 900, 1, sourcePlayer, dimension )
			setTimer ( setElementPosition, 1000, 1, sourcePlayer, x, y, z )
			setTimer ( setPlayerRotation, 1000, 1, sourcePlayer, r )
			-- Fade the camera to make it look nicer
			fadeCamera ( sourcePlayer, false, 1, 0, 0, 0 )
			-- Fade it back once it's all complete!
			setTimer ( fadeCamera, 1000, 1, sourcePlayer, true, 1 )
		end
	else
		-- No player by the specified name was found, tell the warper this.
		outputChatBox ( "No such player.", sourcePlayer )
	end
end
addCommandHandler ( "warpto", consoleWarpTo )
