Problem with setVehicleEngineState

[Liquidz]

Hello Community!

I have a little problem with my Vehiclesystem...

I am setting the vehicleEngine Client-side with a bindKey-function.

Now i created this function server-side to do some other stuff but he always return true?

function vehicleTimer() 
    for i,v in ipairs(getElementsByType("vehicle")) do 
        local speed = (function(velX, velY, velZ) return ((velX^2 + velY^2 + velZ^2)^(0.5)) * 180 end)(getElementVelocity(v)) 
         
        local state = getVehicleEngineState(v) 
        if state then  
            -- state is always true 
        end 
    end 
end 

Although my vehicle engine is turned off he always return true...

Can somebody help me please?

tried using:

return false 

?

Could it be that the client-side setVehicleEngineState(vehicle) only set the Engine client-side

and that server-side the same vehicle has the engine running?

Client side will work for only one player/ped that executed the function, use server side for all of this.

Edit: If you create a vehicle via Client-side, it won't work, it will be as display only

ah ok thanks^^

bindKey("m", "down", 
    function(key, keyState) 
        if key ~= "m" or keyState ~= "down" then return end 
        if not isPedInVehicle(localPlayer) then return end 
        local vehicle = getPedOccupiedVehicle(localPlayer) 
        if localPlayer ~= getVehicleOccupant(vehicle, 0) then return end 
        if engineStarting then return end 
        if getVehicleEngineState(vehicle) then 
            setVehicleEngineState(vehicle, false) 
        else 
            if getElementData(vehicle, "tank") > 0.0 then 
                playSound('engine.wav') 
                engineStarting = true 
                setTimer(startEngine, 1500, 1, vehicle) 
            else 
                playSound('engineNoFuel.wav') 
            end      
        end 
    end 
) 

When i make this server-side now?

How is the easiest way to play the sounds?

[manve1]

use triggering from server side to client side (( if needed from server side to client and back ))
