DataModel
The Data Model (commonly known as game after the global variable used to access it) is the root of Roblox's parent-child hierarchy. Its direct children are services, such as Workspace and Lighting, that act as the fundamental components of a Roblox game.
Code Samples
Demonstrates using game, the root instance of DataModel, to get services such as Workspace and Lighting.
local Workspace = game:GetService("Workspace")
local Lighting = game:GetService("Lighting")
-- Examples of modifying properties of these services
Workspace.Gravity = 20
Lighting.ClockTime = 4
