setElementSpeed?

[Cronoss]

I'm trying to make a gearbox system; I was testing "setElementSpeed",I used all the parameters needed, but still don't work for some reason, the console and debugscript2 don't send me any error, I put a "iprint" and it prints in the console, so the function "velocittt" runs... here it's the full code:

function getElementSpeed(theElement, unit)
    assert(isElement(theElement), "Bad argument 1 @ getElementSpeed (element expected, got " .. type(theElement) .. ")")
    local elementType = getElementType(theElement)
    assert(elementType == "player" or elementType == "ped" or elementType == "object" or elementType == "vehicle" or elementType == "projectile", "Invalid element type @ getElementSpeed (player/ped/object/vehicle/projectile expected, got " .. elementType .. ")")
    assert((unit == nil or type(unit) == "string" or type(unit) == "number") and (unit == nil or (tonumber(unit) and (tonumber(unit) == 0 or tonumber(unit) == 1 or tonumber(unit) == 2)) or unit == "m/s" or unit == "km/h" or unit == "mph"), "Bad argument 2 @ getElementSpeed (invalid speed unit)")
    unit = unit == nil and 0 or ((not tonumber(unit)) and unit or tonumber(unit))
    local mult = (unit == 0 or unit == "m/s") and 50 or ((unit == 1 or unit == "km/h") and 180 or 111.84681456)
    return (Vector3(getElementVelocity(theElement)) * mult).length
end


function setElementSpeed(element, unit, speed)
    local unit    = unit or 0
    local speed   = tonumber(speed) or 0
	local acSpeed = getElementSpeed(element, unit)
	if acSpeed and acSpeed~=0 then 
		local diff = speed/acSpeed
		if diff ~= diff then return false end
        	local x, y, z = getElementVelocity(element)
		return setElementVelocity(element, x*diff, y*diff, z*diff)
	end
	return false
end


function velocittt(thePlayer, cmd)
	local veh = getPedOccupiedVehicle(thePlayer)
	local speed1set = setElementSpeed(veh, "km/h", 10) ------Doesn't work
end
addCommandHandler("vel", velocittt)

The speed must be constantly set for this function to work. To do this, use a timer or a render to constantly maintain the speed.

I don 't know for sure if it is possible to replace the shooting effect , but I can offer an option to create an object and count the trajectory of the bullet ( and already apply your shader to the object itself )
