I just started scripting and every time I make something I keep thinking is there a way to make this shorter or more efficient and because I don't have much knowledge about it I can't answer it, Here's a script I made for a basic dropper and furnace.

Leaderstats:

game.Players.PlayerAdded:Connect(function(Player)
		
	local leaderstats = Instance.new("Folder",Player)
	leaderstats.Name = "leaderstats"
	
	local Money = Instance.new("IntValue",leaderstats)
	Money.Name = "Money"
	
	local HasTycoon = Instance.new("BoolValue",Player)
	HasTycoon.Name = "HasTycoon"
	
end)

Gate:

local Door = script.Parent

Door.Touched:Connect(function(Hit)
	
	if Hit.Parent:FindFirstChild("Humanoid") then
		local Player = game.Players:GetPlayerFromCharacter(Hit.Parent)
		if not Player.HasTycoon.Value then
			local Owner = Instance.new("StringValue",game.Workspace.Tycoon)
			Owner.Name = "Owner"
			Owner.Value = Player.Name
			Door.Transparency = 1
			Door.CanCollide = false
			Player.HasTycoon.Value = true
			Door.Parent.BillboardGui.TextLabel.Text = ("Owner: "..Player.Name)
		end
	end
	
end)

Dropper

local Button = script.Parent
local ClickDetector = Button.ClickDetector
local Owner = game.Workspace.Tycoon:WaitForChild("Owner")
local Debounce = false

ClickDetector.MouseClick:Connect(function(Player)
	
	if not Debounce then
		if Owner.Value == Player.Name then
			Debounce = true
			Button.BrickColor = BrickColor.new("Camo")
			local Ore = Instance.new("Part",game.Workspace.Tycoon.StarterMine.StarterMineOres)
			Ore.Name = "Ore"
			Ore.BrickColor = BrickColor.new("Fossil")
			Ore.Material = "DiamondPlate"
			Ore.Size = Vector3.new(2,2,2)
			Ore.Position = Vector3.new(Button.Parent.Dropper.Position.X,Button.Parent.Dropper.Position.Y - 2,Button.Parent.Dropper.Position.Z)
			wait(0.3)
			Debounce = false
			Button.BrickColor = BrickColor.new("Lime green")
		end
	end
	
end)

Conveyor Belt:

local ConveyorSpeed = game.Workspace.Tycoon.Purchases.ConveyorSpeed
local ConveyorBelt = script.Parent

while wait() do
	ConveyorBelt.Velocity = ConveyorBelt.CFrame.lookVector * ConveyorSpeed.Value
end

Furnace:

local Lava = script.Parent
local Owner = game.Workspace.Tycoon:WaitForChild("Owner")

Lava.Touched:Connect(function(Ore)

	if Ore.Parent == game.Workspace.Tycoon.StarterMine.StarterMineOres then
		Ore:Destroy()
		game.Players[Owner.Value].leaderstats.Money.Value = game.Players[Owner.Value].leaderstats.Money.Value + 1
	end
	
end)
