[HELP] Count vehicle acceleration from 0 to 100km/h

[JAY.ANN]

Is there a way to count vehicle acceleration from 0 to 100 km/h using vehicle handling data?

With enough testing and tweaking I'm sure it is possible, however you can cheat. You can create every vehicle with a ped in it, give them a forwards control state and measure the time it takes them to accelerate to 100 km/h. This is a way easier solution. Do it with 20 peds in 20 vehicles in the same time and it should be quick enough to do it every now and then.

local screenWidth, screenHeight = guiGetScreenSize ( ) 

function getAccelerationTime(vehicle)
	local acc = 0
	local maxVelocity = getVehicleHandling(vehicle).maxVelocity
	local gearRatio = getVehicleHandling(vehicle).driveType == 'f' and getVehicleHandling(vehicle).engineAcceleration or getVehicleHandling(vehicle).engineAcceleration*getVehicleHandling(vehicle).numberOfGears
	acc = 100/maxVelocity*gearRatio
	return acc
end

function showAccelerationTime()
	if not isPedInVehicle(localPlayer) then return false end
	local vehicle = getPedOccupiedVehicle(localPlayer)
	if not vehicle or getVehicleEngineState(vehicle) == false then return false end
	local acc = getAccelerationTime(vehicle)
	dxDrawText(string.format("%0.2f", acc).." sec", 0, 0, screenWidth, screenHeight, tocolor(255, 255, 255), 1, "pricedown", "center", "center")
end
addEventHandler("onClientRender", root, showAccelerationTime)

I thought about this way, but it seems too complicated

Thank you, I gonna test it and answer about the results!

It doesn't work correctly. It outputs 26.67 sec at the Admiral but my stopwatch says that it's 6.35 sec. I guess it may be because of Drag Multiplier and Interia values

Just type /check

function checkVehicleSpeed()
    local vehicle = getPedOccupiedVehicle(getLocalPlayer())
    local accel = getVehicleHandling(vehicle).engineAcceleration
    local seconds = 100/accel
    outputChatBox("Your vehicle takes " .. seconds .. " seconds to get from 0 to 100km/h")
end
addCommandHandler("check", checkVehicleSpeed)

This one works fine, thank you so much!
