How to Create a Simple AR App with Unity AR
In this section, we will show you how to create a simple AR app with Unity AR that displays a 3D object on a detected plane in the real world. You will learn how to set up an AR scene with basic components, how to add a 3D object as a prefab, how to enable plane detection and placement, and how to test your app on your device.
To create a simple AR app with Unity AR, follow these steps:
In the Project window, go to Assets > Scenes and open the SimpleAR scene from the AR Foundation Samples package. This scene contains some basic components for AR development, such as an AR Session, an AR Session Origin, and an AR Camera.
In the Hierarchy window, select the AR Session Origin object and expand it. You will see two child objects: AR Camera and AR Raycast Manager. The AR Camera is the main camera that renders the AR content. The AR Raycast Manager is a component that allows you to perform raycasts against detected planes and features in the real world.
Right-click on the AR Session Origin object and select XR > AR Default Plane. This will add a plane object with a default material that shows a grid pattern on detected planes. You can customize the material and the size of the plane as you wish.
Right-click on the AR Session Origin object again and select XR > AR Plane Manager. This will add a component that enables plane detection and management in your app. You can adjust the settings of the component, such as the plane detection mode, the plane classification, and the plane prefab.
In the Project window, go to Assets > Models and find a 3D object that you want to display in your app. For example, you can use the Andy model from the ARCore XR Plugin package. Drag and drop the model into the scene and make it a child of the AR Session Origin object.
Select the model object and adjust its position, rotation, and scale as you wish. You can also add some components to it, such as a collider, a rigidbody, or an animator.
Right-click on the model object and select Create > Prefab. This will create a prefab of your model that you can instantiate in your app. Drag and drop the prefab into the Assets folder.
In the Hierarchy window, select the AR Raycast Manager object and add a new script component to it. Name it PlaceObjectOnPlane. This script will handle the logic of placing your model on a detected plane when you tap on the screen.
Double-click on the script to open it in your code editor. You can use any editor you prefer, such as Visual Studio or VS Code. In the script, add the following code:
```csharp using UnityEngine; using UnityEngine.XR.ARFoundation; using UnityEngine.XR.ARSubsystems; public class PlaceObjectOnPlane : MonoBehaviour // A reference to the AR Raycast Manager component private ARRaycastManager arRaycastManager; // A reference to the prefab of your model public GameObject objectPrefab; // A list of raycast hits private static List hits = new List(); // A variable to store the instance of your model private GameObject spawnedObject; // A method that runs when the script is attached to an object private void Awake() // Get the AR Raycast Manager component from the same object arRaycastManager = GetComponent(); // A method that runs every frame private void Update() // Check if there is any touch input if (Input.touchCount > 0) // Get the first touch Touch touch = Input.GetTouch(0); // Check if the touch is in the began phase if (touch.phase == TouchPhase.Began) // Perform a raycast from the touch position against detected planes if (arRaycastManager.Raycast(touch.position, hits, TrackableType.PlaneWithinPolygon)) // Get the pose of the first hit Pose pose = hits[0].pose; // Check if there is already an instance of your model in the scene if (spawnedObject == null) // Instantiate a new instance of your model at the hit pose spawnedObject = Instantiate(objectPrefab, pose.position, pose.rotation); else // Move and rotate the existing instance of your model to the hit pose spawnedObject.transform.position = pose.position; spawnedObject.transform.rotation = pose.rotation; ```
Save and return to Unity. In the Inspector window, select the PlaceObjectOnPlane script component and drag and drop your model prefab into the Object Prefab field.
You have completed creating your simple AR app with Unity AR. Now you can test it on your device.
How to Test Your App on Your Device
To test your app on your device, you need to build and run it from Unity. The process of building and running your app on your device may vary depending on the platform and the publishing format you choose. For example, if you want to build an app for iOS devices using ARKit, you need to have Xcode installed on your Mac and a valid Apple developer account. If you want to build an app for Android devices using ARCore, you need to have Android Studio installed on your computer and a valid Google developer account.
For more details on how to build and run your app on different platforms and formats, you can refer to the following resources:
Once you have built and run your app on your device, you can enjoy your simple AR app with Unity AR. You can tap on the screen to place your 3D object on a detected plane and move around to see it from different angles. You can also modify the app as you wish by adding more features, such as UI elements, animations, sounds, or interactions.

FAQs
What is the difference between AR Foundation and XR Interaction Toolkit?
AR Foundation is the core framework that enables cross-platform AR development in Unity. It provides access to the common features of different AR platforms, such as plane detection, image tracking, face tracking, and more. XR Interaction Toolkit is an optional package that provides additional features for creating interactive AR experiences in Unity. It provides components and tools for handling input, gestures, physics, UI, and more.
How can I test my app in the Unity Editor?
You can test your app in the Unity Editor by using the AR Simulation package. This package allows you to simulate AR features in the Editor without having to deploy your app to a device. You can use keyboard and mouse input or a webcam feed to simulate touch input and camera movement. You can also use predefined environments or custom images as backgrounds for your AR scene.
How can I optimize my app for performance and battery life?
You can optimize your app for performance and battery life by following some best practices for AR development in Unity. Some of these best practices are:
Use low-poly models and textures with appropriate compression settings.
Use baked lighting and shadows instead of real-time lighting and shadows.
Use occlusion culling and frustum culling to reduce the number of objects rendered on the screen.
Use LOD (level of detail) groups to reduce the complexity of objects based on their distance from the camera.
Use asset bundles or addressables to load assets asynchronously and reduce memory usage.
Use profiling tools to identify and fix performance bottlenecks and issues.
How can I monetize my app or add ads to it?
You can monetize your app or add ads to it by using the Unity Monetization package. This package allows you to integrate various monetization and advertising solutions in your app, such as Unity Ads, Unity IAP, Unity Analytics, and more. You can use these solutions to generate revenue from your app by displaying ads, offering in-app purchases, collecting user data, and more.
How can I publish my app to the app stores or share it with others?
You can publish your app to the app stores or share it with others by following the guidelines and requirements of each platform and store. You need to prepare your app for distribution by signing it, adding metadata, creating icons and screenshots, and more. You also need to submit your app for review and approval by the store before it can be published. You can use the Unity Distribution Portal (UDP) to simplify and streamline the process of publishing your app to multiple stores. 44f88ac181
