Services

Services are dynamically loaded singletons. The service loader assigns each service its name, parents it to the data model, and gives it BaseClass = "Singleton".

Get a service

local RunService = game:GetService("RunService")
local Players = game:GetService("Players")
local TweenService = game:GetService("TweenService")

The data model also proxies service names, but explicit GetService() calls are clearer and make plugin security checks obvious.

Plugin intents and capabilities

Some services declare plugin intents/capability requirements. In a plugin execution context, GetService() can deny access when the plugin has not requested the needed intent. Treat direct access to graphics, threading, filesystem, networking, and other engine-facing capabilities as privileged surfaces.

Service lifetime

Do not create service objects manually. Retrieve the singleton owned by game.
