getElementSpeed not working

[hackermagus]

Hi

I made a script

local vehicle = createVehicle(596, 2392.09009, -1729.73193, 13.38281, 0, 0, 90)
local ped = createPed(281, 2400, -1735, 13.38281)

local ownSpeed = getElementSpeed(vehicle, 1)

setVehicleSirensOn(vehicle, true)

warpPedIntoVehicle(ped, vehicle)


setPedControlState(ped, "accelerate", true)

if (ownSpeed > 29) then
    setPedControlState(ped, "brake_reverse", true)
end

And when I start the game in debugscript 3 it says "attempt to call global 'getElementSpeed' (a nil value)'"

Because getElementSpeed is an 'useful' function.

You need to paste the function's source into your code.

addEventHandler("onClientResourceStart", root,
function ()
    local ownSpeed = getElementSpeed(vehicle, 1)
end)

Like this? This not work to

Nope.

Okay, I don't get any error message but the vehicle is currently go faster then 30 km/h.

I try

setPedControlState(ped, "accelerate", false)

But it's not help.

Because you are getting the vehicle's speed at the resource startup. You'll have to use a timer to check more than once.

Like a for loop?

Not completely.

Your code runs once when you start the resource.

But, every ~0.5-1th seconds you should check how fast the car.
