Countdown

Lesson 3 of 18 in Coddy's Roblox Game: Disaster Survival course.

Before every round the board counts down: Intermission: 5, 4, 3, 2, 1. Two tools make that.

A function gives a job a name. Every message in this game goes through one:

local function setStatus(text)
	status.Text = text
end

setStatus("Hello")

A numeric for loop can count down: its third number is the step, and -1 goes down one at a time. task.wait(1) pauses the script for a second, so the loop takes one second per number:

for seconds = 3, 1, -1 do
	print(seconds)
	task.wait(1)
end
print("Go!")

This prints 3, 2 and 1 a second apart, then Go! The countdown's length comes from Settings.Intermission, so changing the setting changes the game.

Challenge

Easy

At the bottom of the script:

Write local function setStatus(text) that sets the Status label's Text.
Count down from Settings.Intermission to 1, a second apart, showing Intermission: 5, Intermission: 4 and so on.
After the countdown, show Get ready!

Press Play and watch the board, then Check.

Try it yourself

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

print("Rounds last " .. Settings.RoundLength .. " seconds")

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

	local wins = Instance.new("IntValue")
	wins.Name = "Wins"
	wins.Parent = leaderstats
end)

-- The status board in the lobby
local gui = Instance.new("SurfaceGui")
gui.Parent = workspace.StatusBoard

local status = Instance.new("TextLabel")
status.Name = "Status"
status.Size = UDim2.fromScale(1, 1)
status.BackgroundColor3 = Color3.fromRGB(25, 25, 35)
status.TextColor3 = Color3.fromRGB(255, 255, 255)
status.TextScaled = true
status.Text = "Welcome to Disaster Survival!"
status.Parent = gui
