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.

Wiring the menu buttons

When the user presses a main menu button to add an object to the scene, the button will tell PlaceObjectMode which prefab is to be instantiated. Then PlaceObject mode is enabled, which prompts the user to tap to place the object and handles the user input action. Let's set up the menu buttons now using the following steps:

  1. Unfold the Main Menu game object in the Hierarchy by navigating to UI Canvas / Main UI / Main Menu and select the Cube Button object.
  2. In its Inspector, on the Button component, in its OnClick section, press the + button in the bottom right to add an event action.
  3. From the Hierarchy, drag the PlaceObject Mode object onto the OnClick Object slot.
  4. In the Function selection list, choose PlaceObject Mode | SetPlacedPrefab.
  5. In the Project window, locate a cube model prefab to use. For example, navigate to your Assets/ARF-samples/Prefabs/ folder and drag the AR Placed Cube prefab into the Game Object slot for this click...
