The Conveyor

Lesson 3 of 18 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:

conveyor.AssemblyLinearVelocity = Vector3.new(8, 0, 0)

The vector says which way and how fast: 8 studs a second along X. The speed lives in Settings.BeltSpeed.

Challenge

Easy

Set tycoon.Conveyor.AssemblyLinearVelocity to Settings.BeltSpeed studs a second along X.

Press Play and watch the ore ride (and hop on the belt yourself). 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)
