Overview of this book

Augmented reality applications allow people to interact meaningfully with the real world through digitally enhanced content. The book starts by helping you set up for AR development, installing the Unity 3D game engine, required packages, and other tools to develop for Android (ARCore) and/or iOS (ARKit) mobile devices. Then we jump right into the building and running AR scenes, learning about AR Foundation components, other Unity features, C# coding, troubleshooting, and testing. We create a framework for building AR applications that manages user interaction modes, user interface panels, and AR onboarding graphics that you will save as a template for reuse in other projects in this book. Using this framework, you will build multiple projects, starting with a virtual photo gallery that lets you place your favorite framed photos on your real-world walls, and interactively edit these virtual objects. Other projects include an educational image tracking app for exploring the solar system, and a fun selfie app to put masks and accessories on your face. The book provides practical advice and best practices that will have you up and running quickly. By the end of this AR book, you will be able to build your own AR applications, engaging your users in new and innovative ways.

Selecting an image to use

The next thing we want to do is create an image select menu containing image buttons for the user to choose a photo before adding it to the scene. When the Add button is pressed, rather than immediately prompting the user to place a picture on the wall, we'll now present a menu of pictures to select from before hanging the image chosen on the wall. I'll call this SelectImage mode. We'll need to write an ImageButtons script that builds the menu using the Images list you've already added to the project (the Image Data game object). And then we'll insert the SelectImage mode before AddPicture mode, so the selected image is the one placed on the wall. Let's define the SelectImage mode first.

Creating the SelectImage mode

When SelectImage mode is enabled by the user, all we need to do is display the SelectImage UI menu panel with buttons for the user to pick which image to use. Clicking a button will notify the mode script by...
