# GameObjects

> Understand GameObjects, which are a fundamental Unity concept that make up the building blocks of your application.

GameObjects are the essential building blocks of any Unity project. Everything you interact with in a Unity scene is a GameObject, from characters and environments, to cameras and lights. GameObjects are simple containers that you add components to, to transform them into the elements of your application.
