GameObjects and components

We talked about our project being composed of Assets, and that a Scene (which is a specific type of Asset) is composed of GameObjects; so, how can we create an object? Through a composition of components.

In this section, we will cover the following concepts related to components:

• Understanding components
• Manipulating components

Let's start by discussing what a component is.

Understanding components

A component is one of several pieces a GameObject can be made of; each one is in charge of different features of the object. There are several components that Unity already includes that solve different tasks, such as playing a sound, rendering a mesh, applying physics, and so on; however, even though Unity has a large number of components, we will eventually need to create custom components, sooner or later.

In the next screenshot, you can see what Unity shows us when we select a GameObject.
