The Conveyor

Lesson 3 of 22 in Coddy's Roblox Game: Factory Tycoon course.

Ore piling up under the dropper earns nothing. It has to travel to the collector, and a conveyor takes it there.

In Roblox a conveyor is an anchored part with a velocity. Setting AssemblyLinearVelocity on an anchored part moves nothing by itself, but whatever rests on it is carried along at that speed, players included:

tycoon.Conveyor.AssemblyLinearVelocity = Vector3.new(12, 0, 0)

The vector says which way and how fast: 12 studs a second along X. Your game's speed lives in Settings.BeltSpeed.

Challenge

Easy

Run the conveyor so it carries the ore to the collector.

Under the dropper code, set tycoon.Conveyor.AssemblyLinearVelocity.
Make it Vector3.new(Settings.BeltSpeed, 0, 0): BeltSpeed studs a second along X.

Press Play: the ore rides the belt to the green block, and so do you if you hop on. Then Check.

Try it yourself

local Players = game:GetService("Players")
local Settings = require(game.ReplicatedStorage.Settings)

local tycoon = workspace.Tycoon

print("Ore is worth " .. Settings.OreValue .. " Cash")

-- Every player gets Cash on the leaderboard
Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player

	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Parent = leaderstats
end)

-- Ore: a small part worth Cash, dropped under a dropper
local function dropOre(dropper)
	local ore = Instance.new("Part")
	ore.Name = "Ore"
	ore.Size = Vector3.new(1, 1, 1)
	ore.Color = Color3.fromRGB(150, 150, 160)
	ore.Position = dropper.Position - Vector3.new(0, 2.5, 0)
	ore:SetAttribute("Value", Settings.OreValue)
	ore.Parent = workspace
end

local function startDropper(dropper)
	task.spawn(function()
		while dropper:IsDescendantOf(workspace) do
			dropOre(dropper)
			task.wait(Settings.DropInterval)
		end
	end)
end

startDropper(tycoon.Dropper)
