Using AR Foundation

In this section, we will examine the following AR Foundation concepts:

Creating an AR Foundation project
Using tracking features

Let’s start by discussing how to prepare our project so that it can run AR Foundation apps.

Creating an AR Foundation project

Transitioning to AR development not only changes coding practices but also the game design approach. For instance, in AR, user interaction and camera control are significantly different.

Something to consider when creating AR projects is that we will change not only the way we code our game but also the game design aspect. AR apps have differences, especially in the way the user interacts, and also limitations, such as the user being in control of the camera all the time. We cannot simply port an existing game to AR without changing the very core experience of the game. That’s why, in this chapter, we are going to work on a brand-new project; it would be too difficult...
