Car script questions

Help and Feedback Scripting Support
#1

As i have looked into scripting a car,would it be easier to script a car from scratch or use the script above using DriverSeat the only thing i dont like about DriverSeat is thisimage

local car = script.Parent
local stats = car.Configurations
local Raycast = require(script.RaycastModule)

local mass = 0

for i, v in pairs(car:GetChildren()) do
	if v:IsA("BasePart") then
		mass = mass + (v:GetMass() * 196.2)
	end
end

local bodyPosition = car.Chassis.BodyPosition
local bodyGyro = car.Chassis.BodyGyro

--local bodyPosition = Instance.new("BodyPosition", car.Chassis)
--bodyPosition.MaxForce = Vector3.new()
--local bodyGyro = Instance.new("BodyGyro", car.Chassis)
--bodyGyro.MaxTorque = Vector3.new()

local function UpdateThruster(thruster)
	-- Raycasting
	local hit, position = Raycast.new(thruster.Position, thruster.CFrame:vectorToWorldSpace(Vector3.new(0, -1, 0)) * stats.Height.Value) --game.Workspace:FindPartOnRay(ray, car)
	local thrusterHeight = (position - thruster.Position).magnitude
	
	-- Wheel
	local wheelWeld = thruster:FindFirstChild("WheelWeld")
	wheelWeld.C0 = CFrame.new(0, -math.min(thrusterHeight, stats.Height.Value * 0.8) + (wheelWeld.Part1.Size.Y / 2), 0)
	-- Wheel turning
	local offset = car.Chassis.CFrame:inverse() * thruster.CFrame
	local speed = car.Chassis.CFrame:vectorToObjectSpace(car.Chassis.Velocity)
	if offset.Z < 0 then
		local direction = 1
		if speed.Z > 0 then
			direction = -1
		end
		wheelWeld.C0 = wheelWeld.C0 * CFrame.Angles(0, (car.Chassis.RotVelocity.Y / 2) * direction, 0)
	end
	
	-- Particles
	if hit and thruster.Velocity.magnitude >= 5 then
		wheelWeld.Part1.ParticleEmitter.Enabled = true
	else
		wheelWeld.Part1.ParticleEmitter.Enabled = false
	end
end

car.DriveSeat.Changed:connect(function(property)
	if property == "Occupant" then
		if car.DriveSeat.Occupant then
			car.EngineBlock.Running.Pitch = 1
			car.EngineBlock.Running:Play()
			local player = game.Players:GetPlayerFromCharacter(car.DriveSeat.Occupant.Parent)
			if player then
				car.DriveSeat:SetNetworkOwner(player)
				local localCarScript = script.LocalCarScript:Clone()
				localCarScript.Parent = player.PlayerGui
				localCarScript.Car.Value = car
				localCarScript.Disabled = false
			end
		else
			car.EngineBlock.Running:Stop()
		end
	end
end)

--spawn(function()
	while true do
		game:GetService("RunService").Stepped:wait()
		for i, part in pairs(car:GetChildren()) do
			if part.Name == "Thruster" then
				UpdateThruster(part)
			end
		end
		if car.DriveSeat.Occupant then
			local ratio = car.DriveSeat.Velocity.magnitude / stats.Speed.Value
			car.EngineBlock.Running.Pitch = 1 + ratio / 4
			bodyPosition.MaxForce = Vector3.new()
			bodyGyro.MaxTorque = Vector3.new()
		else
			local hit, position, normal = Raycast.new(car.Chassis.Position, car.Chassis.CFrame:vectorToWorldSpace(Vector3.new(0, -1, 0)) * stats.Height.Value)
			if hit and hit.CanCollide then
				bodyPosition.MaxForce = Vector3.new(mass / 5, math.huge, mass / 5)
				bodyPosition.Position = (CFrame.new(position, position + normal) * CFrame.new(0, 0, -stats.Height.Value + 0.5)).p
				bodyGyro.MaxTorque = Vector3.new(math.huge, 0, math.huge)
				bodyGyro.CFrame = CFrame.new(position, position + normal) * CFrame.Angles(-math.pi/2, 0, 0)
			else
				bodyPosition.MaxForce = Vector3.new()
				bodyGyro.MaxTorque = Vector3.new()
			end
		end
	end

The bar? If the bar is what you don’t like you can turn it off in properties.

Ok this is my first year scripting my most lines of code is around 100,adn the car script is a lil diffcult,if anybody could explain to me how the script works

I’d recommend hooking this to GetPropertyChangedSignal(“Occupant”), simply checks to see if a player sits down in the seat, if it does start the engine with noise and give the client a local script (can’t really go into much detail about the local script). If no player is found then kill the engine.

this is getting the distance from the ground to the thruster position, in order to handle “suspension” of the wheel, giving it a proper position.

Uses the distance (from the thruster to the ground) along with half the size of the wheel, to determine the positioning of the wheel itself.

the direction to rotate the wheel, based on currentrotation * rotation * direction.

Uses the function you created above, to update all the thrusters, and their corresponding wheels.

if the seat has an occupant
ratio is the current speed / whatever the stats.Speed.Value,
changes the pitch of the car engine sound to increase based on said speed.
sets the maxforce, and torque to blank Vectors.
if there isn’t an occupant
it checks to see if it is on a part, if it is then it appears to lock the car in place, if it isn’t then it sets those properties to blank vectors, and it seems like it’d just fall to it’s inevitable doom.
