get vehicle speed (km/h)

[dragonofdark]

Hello,

I would like to make an automatic radar wich fade the player's screen for 0.5 secondes if his vehicle's speed is > than 90 km/h.

I took the code wich calculate the vehicle's speed in km/h in the MTA-paradise speedometer but it seem to dont work.

Here is my code :

  
myMarker1 = createMarker(1630.8,154.3,34.1,"cylinder",15,255,255,10,0) 
  
function MarkerHit1 ( hitElement, matchingDimension ) 
    if getElementType( hitElement ) == "vehicle" then 
        vehicle = hitElement 
        controller = getVehicleController ( vehicle ) 
        speed = ( function( x, y, z ) return math.floor( math.sqrt( x*x + y*y + z*z ) * 155 ) end )( getElementVelocity( vehicle ) ) 
         
            function vitesse () 
                if speed then 
                    if speed > 90 then 
                        function flash (controller) 
                            fadeCamera ( controller, false, 1.0, 0, 0, 0, 255 ) 
                            setTimer ( fadeCamera, 500, 0.5, controller, true, 0.5) 
                        end 
                    end 
                end 
            end 
    end 
end 
addEventHandler( "onMarkerHit", myMarker1, MarkerHit1 ) 

My screen don't fade if I pass at 110mk/h on the marker.

Could you help me ?

Thanks.

because your "vitesse" function is never called.

and why are creating yet another function inside that function and never call it either?

you dont need to create a function every line, you know.

myMarker1 = createMarker(1630.8,154.3,34.1,"cylinder",15,255,255,10,0) 
  
function MarkerHit1 ( hitElement, matchingDimension ) 
    if getElementType( hitElement ) == "vehicle" then 
        local vehicle = hitElement 
        local controller = getVehicleController ( vehicle ) 
        local speed = ( function( x, y, z ) return math.floor( math.sqrt( x*x + y*y + z*z ) * 155 ) end )( getElementVelocity( vehicle ) ) 
        if speed and speed > 90 then 
            fadeCamera ( controller, false, 1.0, 0, 0, 0, 255 ) 
            setTimer ( fadeCamera, 500, 0.5, controller, true, 0.5) 
        end 
    end 
end 
addEventHandler( "onMarkerHit", myMarker1, MarkerHit1 )
