Help and Feedback Scripting Support
#1

Hey devs, I’m looking to figure out how to make it that a script will automatically stop a car when a player exits the car. This is my script for far:

local seat = script.Parent
wheel1 = script.Parent.Parent.Parent.WheelBL.Wheel.Hub 
wheel2 = script.Parent.Parent.Parent.WheelBR.Wheel.Hub
seat:GetPropertyChangedSignal("Occupant"):Connect(function()
	if seat.Occupant then
		print("Driver in car")
	else
		print("No driver")
		while true do
			wait (0.1)
			local wlsp = (wheel2.RotVelocity)
			print(wlsp)
			if wlsp <= 0.005 then
				seat.Throttle = -1
			end
	end
	end
end)

When I run the game, it gives me the error “Workspace.Car.Base.VehicleSeat.BrakeOnExit:13: attempt to compare Vector3 <= number”. Anyone know what is happening and how to fix it?

You could make use of the MaxSpeed property to achieve this. Unless the speed of the vehicle is handled in some other way.

wlsp is a Vector3 value (RotVelocity), and you can’t compare Vector3 values with numbers. In other words, the computer doesn’t understand “wlsp <= 0.005”.

All Vector3 values have a magnitude, though, which is basically the overall size, length, or strength of the value. To access this, you can write Vector3Value.Magnitude. In your case, this would be:

local wlsp = wheel2.RotVelocity.Magnitude
