Speedlimiter Problem

[Karuzo]

Hey Guys,

i have a small problem with my Speed-Limiter Script.

curMaxSpeed = false 
  
function limit_func ( cmd, amount ) 
  
    local amount = tonumber ( amount ) 
    if amount then 
        local amount = math.abs ( amount ) 
        curMaxSpeed = amount 
        --curMaxSpeed = curMaxSpeed*0.00464 
        if not isTimer ( curMaxSpeedTimer ) then 
            curMaxSpeedTimer = setTimer ( fixSpeed, 50, -1 ) 
        end 
        outputChatBox ( "Maximale Geschwindigkeit auf "..amount.." Km/h gesetzt. Verwende /stoplimit, um den Tempomat zu entfernen.", 150, 150, 0 ) 
    else 
        outputChatBox ( "Bitte gib eine gültige Km/h Zahl an!", 125, 0, 0 ) 
    end 
end 
addCommandHandler ( "limit", limit_func ) 
  
function stoplimit_func () 
  
    if not curMaxSpeed then 
        outputChatBox ( "Du hast momentan den Tempomat nicht aktiviert. Verwende /limit [Km/h], um ihn zu aktivieren!", 150, 0, 0 ) 
    else 
        curMaxSpeed = false 
        killTimer ( curMaxSpeedTimer ) 
        outputChatBox ( "Tempomat wurde entfernt!", 0, 150, 0 ) 
    end 
end 
addCommandHandler ( "stoplimit", stoplimit_func ) 
  
function fixSpeed () 
  
    local veh = getPedOccupiedVehicle(lp) 
    if veh then 
        if isVehicleOnGround ( veh ) and getPedOccupiedVehicleSeat ( lp ) == 0 then 
            local vx, vy, vz = getElementVelocity(veh) 
            local speed = math.sqrt(vx^2 + vy^2 + vz^2) 
            local kmh = speed * 180 
            if kmh > curMaxSpeed then 
                setElementVelocity ( veh, vx*0.97, vy*0.97, vz*0.97 ) 
            end 
        end 
    end 
end 

It outputs the message that the limit was set, but the caar doesn't really limit at that speed.

No errors.

Where is fixSpeed called?

I suggest you using getElementSpeed and setElementSpeed, thats easier too handle.

line 11,

gonna check it out thx.

Ah, I see, but why do you use -1?

Idk,

i saw it somewhere
