Objects and components

Before we get to the heart of building our project, let's take a few minutes to talk about objects and components. I wish I had understood some of these ideas much earlier on; it would have sped up my overall understanding of Unity. We will only lightly touch on these subjects for now. We will go into greater detail in later chapters.

Objects

Objects or GameObjects are what make up nearly everything in Unity. The characters, camera, 3D text, and lights are all a very basic-level GameObjects. Everything you see in a Unity-developed project is either GameObjects, or connected to them.

These objects are created to perform a function, such as to keep game scores or to handle network traffic. The one common element that all GameObjects share is the Transform component:
