Luau (programming language)

Luau is a Programming Language based on Lua and developed by Roblox Corporation and used in Roblox Studio to create games on Roblox.

Examples

Instances refers to objects in the game and some of them can be parented and some have a "child".

Part spawns in constant code

Here's an example code for spawning a "Part" (Roblox Block instance, shown here as "brick") every 10 second. Spawning in the position 0, 0, 0. "game" refers to the game itself. "Workspace" is where the player can interact, a 3D environment. "CFrame" is used as the position of "brick".

while wait(10) do
    local brick = instance.new("Part")
    brick.parent = game.Workspace
    brick.position = CFrame.new(0, 0, 0)
end

Function codes

Another example is to use custom functions and instance's "Signal". If the instance has triggered a change, the signal will be fired. In this example, instance "Button" has a "ClickDetector" which fires the signal "MouseClick" whenever "Button" is pressed. "Connect(<Name Of The Function To Run>) is to run the function in the parenthesis whenever the Signal is fired. This time we are going to run a custom function called "onClicked()" and it will change "Button's" colour and material.

Button = script.parent

function onClicked()
button.BrickColor = BrickColor.new("Medium Stone Grey")
button.Material = Enum.Material.DiamondPlate
end

Button.ClickDetector.MouseClick:Connect(onClicked)

Note that "Workspace" is a child of "game". This script is a "Script" instance and it's placed in "ServerScriptService", a parent of "game".
