Slight issue in your code. seat.Occupant has the humanoid of the player, not the character. Character should instead be defined as

local character = seat.Occupant.Parent

Also, the start of the function should check if the occupant actually exists, and the event wasn’t fired by someone leaving the seat.
Something using

if seat.Occupant then
 -- normal code
else
  -- player left the seat code
end

would help ensure it is correct

No, I already know how to detect if the player is sitting in a seat. I want to know how to measure how fast the vehicle is going and put the Value on a GUI.

Using the power of physics, the formula for speed is the distance over time. You can use Heartbeat to track how fast the vehicle is moving by taking
(position1 - position2)/(amount of time you want to wait)

I want a script, not a math problem.

#9

Ok, first of all, you are not entitled to a script. As a matter of fact, we aren’t supposed to give you direct scripts:

Anyway, you’re in luck because not much math is needed… If you want it in studs/s, that is.

You can find the velocity by checking the player’s character model’s AssemblyVelocity. To get it as a scalar, just use AssemblyVelocity.Magnitude

20 studs is 1 meter. Therefore, mps = sps / 20

To convert m/s into mi/hr, you just multiply by 2.237. (From Google)

If you just want the answer, here it is:

-- THIS IS A SCRIPT WITH RunContext SET TO Client

local seat = script.Parent

-- seat.Occupant will be nil at first so you need to check it via GetPropertyChangedSignal,this is just an example
local char = seat.Occupant.Parent
local occupantPlayer = game.Players:GetPlayerFromCharacter(char)

local carGui = occupantPlayer.PlayerGui.YourCarGui
local mphCounter = carGui.MphCounter

local carRoot = ... -- This is the root part of your car or vehicle.

local velStps = carRoot.AssemblyVelocity
local velMps = velStps / 20
local velMiphr = velMps * 2.23

mphCounter.Text = `Mph: {velMiphr}`
print("Tada", velMiphr)

You’ll need to do this in RunService.Heartbeat.

Sorry if I went off the rails at the beginning there.

EDIT: I made changes to this script as my previous example was wrong. Don’t know what was wrong with me

Sorry, I’m a beginner scripter, and I don’t know how to do all that, which is why I was asking for a script because I don’t know how to do it at all, and there’s no tutorials on YouTube or anyway where else.

#11

Ok, but ask nicely next time.

I also apologize for my outburst, I have edited my original comment with an example.

Of course, seat.Occupant is going to be nil when the script first runs, you have to check whenever Occupant changes (This happens whenever a player gets in or out of the seat) via seat:GetPropertyChangedSignal("Occupant"):Connect ... and then set occupant (your variable) to seat.Occupant inside it.

Then, in a seperate block, create a RunService.Heartbeat connection and check if occupant is not nil, in that case you can use the code I provided.

Try to implement that and share the code you got so I can check it for errors. Or, you can run it in Studio and try to check what’s wrong as well.

Once again, I’m sorry if I stressed you out.

*EDIT: If your script isn’t working, I edited my previous comment because I did some things incorrectly, sorry.

Thank you so much for the script! But where do I put the GUI?

#13

No problem!

You could create a gui and put it under the script as some name, e.g. “CarGui”.

BTW, make sure you script runs with “Client” RunContext and make sure that in the seat.Occupant change make it check that the new occupant is LocalPlayer.

You can then copy the CarGui into the player.PlayerGui when the script starts and set its Enabled property to false.

When the occupant changes and it is == to LocalPlayer, set the Enabled property to true. Otherwise set it to false.

Something like this:

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local player = Players.LocalPlayer

local gui = script.CarGui:Clone()
gui.ResetOnRespawn = false
gui.Parent = player.PlayerGui

local seat = script.Parent -- Or wherever it is

function updateDisplay()
    local velMiphr = ... -- The code from before here.
    gui.MphCounter.Text = `Mph: {velMiphr}`
end

local updateConnection
seat:GetPropertyChangedSignal("Occupant"):Connect(function()
    if seat.Occupant == player.Character.Humanoid then
        player.PlayerGui.CarGui.Enabled = true
        updateConnection = RunService.Heartbeat:Connect(updateDisplay)
    else
        player.PlayerGui.CarGui.Enabled = false
        if updateConnection then
            updateConnection:Disconnect()
        end
    end
end)

In this example, I hook the Heartbeat event whenever the player sits in the car, and disconnect it when they jump out. This is different from my previous examples. Sorry for my inconsistency.

Thanks again, but I got this error:

Oh yes well that is the code that I sent before, you know the one to calculate mph?

But, you have to set local carRoot = to the root part of the car. This is very important or it won’t owrk.

#16

I’m sorry but I got a new error again:

I think they just got the wrong property name, I’m pretty sure it should be gui.ResetOnSpawn instead of gui.ResetOnRespawn

Thanks, I got that error but now I got this one:

If it is a LocalScript then you need to wait for its children to load in using WaitForChild()

#20

That error message is saying that the player variable is nil, so player = Players.LocalPlayer is not working as intended.

The LocalPlayer variable is only functional from code running on the client, so what you should do is remake this script as a LocalScript and place it under StarterPlayerScripts or StarterGui (up to you).

You’ll also have to change the local seat = ... to where the seat is.

#21

So basically how would the entire script look like? Is it okay if you could re-write it?

#22

Don’t worry I’ll send you the script to modify (if u want)!

#23

I mean no offense but you should probably learn some scripting yourself before going onto scripting support. That said, you only need to rewrite one line, you just have to rearrange where things are in the game is all.

I’ll be more specific on what you need to do, although I’m afraid I can’t help you more than this:

  1. Create a new LocalScript under StarterPlayer > StarterPlayerScripts
  2. Copy and paste the code you have into the new LocalScript
  3. Move the CarGui from the old script to under the new LocalScript
  4. On line 9, you’ll have to change the directory of the seat (seat isn’t this LocalScript’s parent!)

For example if the seat is named “Seat” under the workspace you would write.

local seat = workspace:WaitForChild("Seat")
