Extras are additional vehicle components that can be turned on or off. They are often: police lights, luggage racks, ladders, spoilers, bullbars, different versions of body parts. This allows for greater customization of vehicles without the need for multiple models.

❓ How do extras work in practice?
In the vehicle model files, the author defines so-called extra components, which have their own numbers (e.g. extra_1-9, extra_ten, extra_11, extra_12).
The player can activate/deactivate them using the appropriate script (Mechanic Job, vMenu, Tuning Menu).

❓How do extras work in our vehicles?
In our vehicles, extras function as police lights. We do not force police lights when spawning a vehicle, as not everyone may like it, although we will describe how to force them later in the documentation.

❓How to force extras every time a vehicle is spawned?
There are two best options for this - Forcing by using a script, forcing by configuring the vehicles.meta file (recommended).

➡️First Option:
Forcing extras through a script:

Example code:

RegisterCommand("spawnbuffalo", function()
	local playerPed = PlayerPedId() -- Get the player's ped (character)
	local coords = GetEntityCoords(playerPed) -- Get the player's current coordinates

	local model = `nkbuffalos` -- Set the vehicle model name

	RequestModel(model) -- Request the model to be loaded
	while not HasModelLoaded(model) do -- Wait until the model is fully loaded
    	Wait(100)
	end

	local vehicle = CreateVehicle(model, coords.x + 2, coords.y, coords.z, GetEntityHeading(playerPed), true, false) -- Create the 	vehicle 2 units away from the player
	SetPedIntoVehicle(playerPed, vehicle, -1) -- Put the player into the driver seat

	-- Forcing extras
	SetVehicleModKit(vehicle, 0) -- Required before modifying vehicle extras

	-- false = enabled, true = disabled
	SetVehicleExtra(vehicle, 1, false) -- enabled
	SetVehicleExtra(vehicle, 2, true) -- disabled
	SetVehicleExtra(vehicle, 3, false) -- enabled

	-- You can also disable all extras first, then enable selected ones
	-- for i = 0, 12 do
	--     if DoesExtraExist(vehicle, i) then
	--         SetVehicleExtra(vehicle, i, false)
	--     end
	-- end

	-- Optional cleanup
	SetEntityAsNoLongerNeeded(vehicle)
	SetModelAsNoLongerNeeded(model)
end)

➡️Second Option: - Recommended

Forcing extras through configuring the vehicles.meta file:

✅Step One:

Find the “requiredExtras” category in the vehicles.meta file. This is the category that interests you the most.

✅Step Two:
In the game, choose extras that interest you and you want them to activate every time. In my case it will be EXTRA_1, EXTRA_2, EXTRA_4 and EXTRA_5.

✅Step Three:

Add your extras to the category:

✅Step Four:
Restart your server and check if everything works - Everything should work.
