This function sets the velocity (movement speeds) along each axis, for an element.

This is not compatible with all elements. Only the following element types are compatible:

Syntax

bool setElementVelocity ( element theElement, float speedX, float speedY, float speedZ )

OOP Syntax Help! I don't understand this!

Method: element:setVelocity(...)
Variable: .velocity
Counterpart: getElementVelocity


Required Arguments

  • theElement: The element you wish to set the velocity of.
  • speedX: A floating point value determining the speed along the X axis.
  • speedY: A floating point value determining the speed along the Y axis.
  • speedZ: A floating point value determining the speed along the Z axis.

Returns

Returns true if the speed was set successfully, false if a bad element was specified or other bad arguments.

Server

This example adds a function which copies the speed of a random player to another random player. If there are less than 2 players it returns false. 

function equalTwoRandomPlayersVelocity()
    if getPlayerCount() < 2 then -- If there's only one player (or no players) this doesn't make sense
        return false
    end
    local randomPlayer1, randomPlayer2 = getRandomPlayer(), getRandomPlayer() -- Get two random players
    while randomPlayer1 == randomPlayer2 do -- Make sure the two players are different
        randomPlayer2 = getRandomPlayer()
    end
    local speedx, speedy, speedz = getElementVelocity (randomPlayer1) -- Get the velocity of the first random player
    setElementVelocity(randomPlayer2, speedx, speedy, speedz) -- Copy that velocity to the second random player
    outputChatBox("Now " .. getPlayerName(randomPlayer2) .. " runs as fast as " .. getPlayerName(randomPlayer1) .. "!", root, 255, 128, 0)
    return true
end

Client

This example lets players jump their vehicle into the air (if they are the driver). 

function initBind()
	bindKey("lshift", "down", jumpKey)
end
addEventHandler("onClientResourceStart", resourceRoot, initBind)

function jumpKey()
	if not isPedInVehicle(localPlayer) then return end

	local vehicle = getPedOccupiedVehicle(localPlayer)
	if vehicle and getVehicleController(vehicle) == localPlayer then
		local vehType = getVehicleType(vehicle)
		if vehType == "Plane" or vehType == "Helicopter" then return end
		local sx, sy, sz = getElementVelocity(vehicle)
		setElementVelocity(vehicle, sx, sy, sz + 0.33) -- The jump effect is achieved by raising the Z axis (height) coordinate
	end
end
