Including AR Foundation in Unity

Introduction

Packages in Unity are collections of assets, scripts, and other resources that can be easily imported and used in our projects. They can include various features, such as UI controls, physics engines, and audio systems.

Packages are essential in Unity because they provide an easy and convenient way to add new functionality to our project without writing all the code ourselves. Using packages, we can save time and effort and benefit from the work of the Unity community and other developers.

There are two types of packages in Unity. They have been given below:

• Built-in packages: These are packages that come preinstalled with Unity and are available for all projects. They include essential features, such as physics, animation, and audio systems.

• Custom packages: External developers or organizations create these, and we can download them from the Unity Asset Store or other sources. They can provide additional functionality and features to our projects, such as improved AI, new UI controls, and more.

To use packages in Unity, we can import them into our project by using the “Package Manager” window in the Unity Editor. From there, we can easily manage and update packages and remove or add new ones as needed.

Here is a step-by-step process for using packages in Unity:

• Open the Unity Editor.

• Click the “Window” tab in the top menu bar and select “Package Manager” from the drop-down list. This action will open the “Package Manager” window.
