Need help with a car gui

[Leoristix]

So, recently i’ve made a car, and figured out how to control it through a gui, but now I don’t really know how can I make a speedometer on the same gui. Maybe a remote function would work? Thanks for help and sorry for my english.

A couple of questions to begin:

• Is this a custom vehicle? (You made it, it’s not a pre-made chassis)
• What type of GUI are we trying to create? Something that would display when the player is driving the vehicle?

1. Yes it’s a custom made vehicle.
2. We’re trying to do a custom speedometer when the player is driving a vehicle.

To get you started on a basic speedometer, here is a quick showcase:

local Speedometer = script.Parent -- Location of speedometer
local CarName = "MyCarName" -- The name of the vehicle in the workspace (You probably already defined this)
local Car = workspace:FindFirstChild(CarName) -- Gets the vehicle from the workspace

local TS = game:GetService("TweenService")
local Info = TweenInfo.new(.05, Enum.EasingSyle.Sine, Enum.EasingDirection.InOut) -- Change however you would like to customize

local Units= {	
	{
		units = "MPH",
		scaling = (10/12) * (60/88), -- 1 stud : 10 inches | ft/s to MPH - Converts SPS to MPH
	},
	
	{
		units			= "KMH",
		scaling			= (10/12) * 1.09728, -- 1 stud : 10 inches | ft/s to KP/H - Converts SPS to KPH
	},
}

local CurrentUnit = 1

game:GetService("RunService").Heartbeat:Connect(function()
	TS:Create(Speedometer, Info, {Rotation = 255 * math.min(1, Units[CurrentUnit].scaling*Car.DriveSeat.Velocity.Magnitude/Car.DriveSeat.MaxSpeed)) 
-- Change the 255 at the start to how far the speedometer rotates when at full speed
end)

Let me know if you have any other questions

What if there are multiple cars in the workspace?

[Fittergem1000 (Fittergem)]

If there are multiple cars in the workspace with the same name you could put this script inside the DriveSeat:

-- Regular Script

local DriveSeat = script.Parent

DriveSeat.ChildAdded:connect(function(Child)
    if Child.Name == "SeatWeld" and Child:IsA("Weld") and game.Players:GetPlayerFromCharacter(Child.Part1.Parent) ~= nil then
        local Player = game.Players:GetPlayerFromCharacter(Child.Part1.Parent)
        DriveSeat.Parent.Name = Player.UserId
    end
end)

Then, inside your speedometer script, you can change the location of your car to this:

-- Local Script

local Player = game.Players.LocalPlayer

repeat wait(.1) until workspace:FindFirstChild(Player.UserId) ~= nil

local Car = workspace:FindFirstChild(Player.UserId)

Let me know if this works or not.

After some modifications it works perfectly! Thank you!

Hello, the script doesn’t work for me I am using a local script and a frame for the speed needle, and it does not rotate at all.

[Fittergem1000 (Fittergem)]

Are you sure that the DriveSeat and the Frame are defined correctly? Also, are you getting any errors?

EDIT: Inside of the script I forgot to make the Tween play. At the end of the line that begins with TS:Create() insert :Play() afterward. This should fix your issue

It worked thank you for the help!
