How the hell do you use vehicle seats?

Help and Feedback Scripting Support
#1

This may sound like a stupid question but I’ve scowered the internet and not found a single solution. Every time I have a vehicle seat, it does not move anything at all.
I’ve tried grouping it with a part, welding it and hinges and attachments and so much more but it never did anything.
Is anyone able to help?

The Vehicle Seat its just an object with properties that by default changes when a Player is using the seat and press keys or touch.

You should listen when those properties changes and get the new value of the property. Grab that value and feed a constraint like hinges or BodyMovers to apply movement into the model.

Place a script like this into the Vehicle Seat, sit on it and press keys like WASD, you will get prints in output, just use those numbers to feed your hinges/motors or physics instances

local vehicleSeat = script.Parent

local function onSteerInputChanged(val)
	print("Steer input:", vehicleSeat.Steer)
end

local function onThrottleInputChanged()
	print("Throttle input:", vehicleSeat.Throttle)
end

vehicleSeat:GetPropertyChangedSignal("Steer"):Connect(onSteerInputChanged)
vehicleSeat:GetPropertyChangedSignal("Throttle"):Connect(onThrottleInputChanged)

… I remember a very silly post I made a few years ago when I started in roblox engine… about this topic… I think it was my very first topic in DevForum… its pretty dumb… emm… but yeah… my dumb thing … I even want to delete it cause I feel kinda embarrased about it… hahah…

Where would I input the numbers into my constraint(sorry if this sounds stupid I’ve basically never used vehicle seats)

You are using Hinge constraints? in Motor ActuatorType? Then just multiply the number and use it for the constraint AngularVelocity:

local maxSpeed = 20
local motor1 = car.Hinge1
motor1.AngularVelocity = seat.Throttle * maxSpeed

I dont even know if those constraints still updated and not deprecated… This is for a very basic car system. Read the posts I made in that topic link I sent, explain all details.
Honestly long time since I dont build a car under that approach.

And I would suggest look for a more updated and advanced approach, like BodyMovers and MoverConstraints
